AB:   Random amplified polymorphic DNA (RAPD) analysis was used to characterize barley germplasm genetic diversity. For the analysis 303 morphologically distinctive accessions were selected from the VIR germplasm collection, St. Petersburg, Russia and the MAFF Genebank, Tsukuba, Japan to represent the principal regions of barley cultivation. A total of 93 polymorphic bands scored from RAPD patterns were used to generate a genetic distance matrix, which was used in both cluster and principal coordinate analysis. Both analysis clearly separated barley cultivars and local populations into three distinctive groups, which evidently reflect different directions in evolution and geographical distribution of barley. The hierarchy of accessions clustering in the first group indicates the westward distribution of barley from West Asia to Europe and New World across Ethiopia and then Mediterranean region. The principal breeding trends based on spike morphology are also observed in this group. The second group is associated with eastward distribution of the crop and represents a unified genetic group, which consists of East Asian and Central Asian accessions. The third distinctive group identified is connected with the evolution and dissemination of hulless forms in Central Asia and the Caucasus region. The conformity of identified genetic groups and clusters with the global centers of crops diversity (gene centers) determined by Vavilov (1926) and modern ecogeographical classification of barley is discussed.

AB:   The following comparisons between crops and their closely related wild relatives provide clues for discriminating between monophyletic and polyphyletic origins under domestication: (i) Presence or absence of patterns indicative of founder effects in the cultivated genepool, compared to the amount of variation present in its wild progenitor. (ii) Uniformity or lack of uniformity (within a crop) in genes governing principal domestication traits (traits that were automatically selected for once the wild progenitor was introduced into cultivation). (iii) Species diversity: The number of closely related (congeneric) wild species with similar potential for domestication, native to the area under consideration; and how many of them entered cultivation. The present paper evaluates the information available on the eight crops that founded Neolithic agriculture in the Near East; and arrives at the conclusion that emmer wheat Triticum turgidum L. subsp. dicoccum Schubler, einkorn wheat T. monococcum L., pea Pisum sativum L., and lentil Lens culinaris Medik. were very likely taken into cultivation only once or-at most-a very few times. Also chickpea Cicer arietinum L., bitter vetch Vicia ervilia (L.) Willd., and flax Linum usitatissimum L. seem to have been domesticated in a similar way, but the evidence concerning them is much scarcer. Only for barley Hordeum vulgare L. are there indications that it has been domesticated more than once--but again only a very few times.

AB:   Differences in physiological characteristics were analysed among accessions/provenances of Aegilops speltoides and between these accessions and the Triticum aestivum cultivar Sparta. The seedlings were cultivated for 21 days in Hoagland 3 nutrient solution. At the end of the experiment, shoot and root dry matter was determined and total plant dry mass and shoot to root ratio were calculated. Daily measurements of the leaf length were used for the calculation of the leaf growth rate and phyllochron intervals. Finally, leaf area of individual leaf blades and the nitrogen content of the whole plant were determined. With few exceptions, no statistically significant differences among accessions of Ae. speltoides were found. Compared to these accessions, T. aestivum cv. Sparta produced considerably more dry matter. This was mainly due to larger leaf blade area, while net assimilation rates were similar. It was concluded that the variability among Aegilops provenances is of minor importance and any of the tested accessions could be used as a representative of Aegilops speltoides for further experiments.

AB:   Hessian fly, Mayetiola destructor (Say), is the major pest of wheat in North Africa. In Morocco, durum wheat (Triticum turgidum L. subsp. durum (Desf). Husn.) losses due to this pest have been estimated at 32%. Genetic resistance is the only economical and practical means of controlling this insect. Field and greenhouse screening of durum wheat genotypes resulted in the identification of one source of resistance to Hessian fly in Morocco. This is the first source of durum wheat Hessian fly-resistance identified in Morocco. This source of resistance expresses a medium level of antibiosis against first-instar Hessian fly larvae; about 25% of the larvae survive on resistant plants. The deployment of varieties that allow for larval survival on resistant plants should reduce selection for biotype development. This source of resistance is being used by CIMMYT/ICARDA and Moroccan breeders to develop resistant durum wheat varieties.

(1997; Plant, Cell and Environment 20, 1439-1450) investigated the correlation of spatial patterns of xyloglucan-endotransglycosylase (XET) activity, XET-related mRNAs, and growth in elongating barley (Hordeum vulgare L.) leaves. Here, methodological difficulties in the kinematic growth analysis are discussed, and it is concluded that the role that XET-related gene activity plays in the control of spatial growth patterns remains undetermined.

AB:   Moisture diffusion during soaking of Kisan maize in water at temperatures ranging from 30 to 90 degrees C was studied. The soaking data were fitted in Becker's model to determine the moisture diffusivity. The moisture diffusivity was found to vary from 3.994x l0(-8) to 40.967x10(-8) m2/h. The energy of activation of maize was found to be 35069.55 kJ/kg mol K. The relationship between moisture diffusivity and reciprocal of absolute temperature followed the Arrhenius equation as D = 0.040107 e-4217.96/Tw. A mathematical model for prediction of moisture content in maize with time, during hot water soaking was developed for known initial moisture content and water temperature as (...).

AB:   Objectives: To assess whether current smokers eat differently than never smokers and the relation of smoking cessation to dietary change. Design: Population-based survey from 1993-1997. Setting: The Bus Sante 2000, epidemiologic observatory of Geneva, Switzerland. Subjects: A representative sample of 2301 men and 2306 women resident of Geneva, Switzerland. Results: In both genders, compared to never smokers, current heavy smokers (greater than or equal to 20 cigarettes/d) consumed daily less total vegetables proteins (P < 0.03), carbohydrates (P < 0.0001), saccharose (P < 0.01), fibers (P < 0.0001), beta-carotene (P < 0.001), fruit (P < 0.0001) and vegetables (P < 0.04), but they drank more alcohol (P < 0.0001) and more coffee (P < 0.005. In addition, female current smokers ate less energy (P < 0.4), complex carbohydrates P < 0.002), cereals (P < 0.003), vegetables (P < 0.0001) and less iron (P < 0.02). The diet of ex-smokers tended to become more similar to that of never smokers. When longer duration of smoking cessation increased, the consumption of total carbohydrates and complex carbohydrates increased (P < 0.01 and P < 0.06), and alcohol decreased (P < 0.07) in both genders. Conclusions: As in other Western countries, the diet of Swiss smokers appears less healthy than that of never smokers in both men and women, while smoking cessation has beneficial aspect on the quality of the diet. Current smoking appears to have an even stronger effect on the diet of women than on the diet of men.

AB:   The filarial parasite Setaria digitata is the causative agent of cerebrospinal nematodiasis in its abnormal hosts such as sheep, goats and horses, and therefore is of significant veterinary importance. Since very little is currently known about the biology of this parasite at molecular level we have cloned and characterised a hsp70 gene, the first gene to be reported from this parasite. The genomic clone isolated contained sequences from two hsp70 genes. One gene hsp70-2, was completely sequenced and found to contain nine introns ranging in size from 78 to 195 bp. The region upstream of the initiation codon contained a putative TATA box, two CAAT box elements and three heat-shock elements. A putative transcription initiation site was also identified. The 5' untranslated region contained a splice acceptor sequence. The gene was typically AT rich, having a GC content of 44.5%. The deduced aa sequence potentially encoded a cytosolic protein of 645 aa, which had three consecutive repeats of a tetrapeptide motif, GGMP, at the carboxyl end. The gene appeared to be constitutively transcribed and was not significantly enhanced in response to heat shock in adult worms. Another hsp70 gene (hsp70-1) was located further upstream, arranged in direct tandem with hsp70-2. Southern blot analysis revealed the presence of two or three additional hsp70-related genes in the S. digitata genome.

AB:   We have developed a PCR-based assay which uses a combination of two classes of repetitive elements found in eukaryotic genomes, namely Ty1-Copia retrotransposons and simple sequence repeats to amplify multiple polymorphic products from total genomic DNA. Usine the technique, seven markers were mapped to four different chromosome arms using a barley doubled haploid mapping population. This technique offers a simple and efficient method of generating both dominant and codominant genetic markers in virtually any eukaryote for mapping and diversity studies.

AB:   Study of bread wheat (Triticum aestivum) may help to resolve several questions related to polyploid evolution. One such question regards the possibility that the component genomes of polyploids may themselves be polyphyletic, resulting from hybridization and introgression among different polyploid species sharing a single genome. We used the B genome of wheat as a model system to test hypotheses that bear on the monophyly or polyphyly of the individual constituent genomes. By using aneuploid wheat stocks, combined with PCR-based cloning strategies, we cloned and sequenced two single-copy-DNA sequences from each of the seven chromosomes of the wheat B genome and the homologous sequences from representatives of the five diploid species in section Sitopsis previously suggested as sister groups to the B genome. Phylogenetic comparisons of sequence data suggested that the B genome of wheat underwent a genetic bottleneck and has diverged from the diploid B genome donor. The extent of genetic diversity among the Sitopsis diploids and the failure of any of the Sitopsis species to group with the wheat B genome indicated that these species have also diverged from the ancestral B genome donor. Our results support monophyly of the wheat B genome.

AB:   Pollination with maize is commonly used to produce fertile doubled haploid plants in durum wheat. However, the genetic basis for the ability of parental lines to produce haploid seedlings is not well documented. A maximum likelihood procedure was used to analyse the response of 15 F(1), from a half diallel design involving six inbred lines, and to document rigorously the existence of heritable variation for haploid embryo production. Cross-effects and "general combining abilities" (GCA) were computed to estimate the ability to produce swollen ovaries and viable embryos. On average, the ovary swelling production was 56% and 11% of emasculated flowers produced a viable embryo. For both variables, cross-effect was significant. Based on GCA estimations, the 6 parental lines could be distributed in 3 different groups. The GCA values explained respectively 69% and 79% of the cross-effect for each variable. On the whole, ovary swelling was a poor predictor of embryo formation. No significant correlation was found between the per se values of the 6 parental lines and their GCA.

In this method, Southern blots of rice YAC DNAs digested with a restriction endonuclease are probed with a rice microsatellite probe, (GGC)5. The probe produces a unique fingerprint profile characteristic of each YAC clone. The profile is then digitized, processed in a computer, and a statistic that represents the degree of overlap between two YACs is calculated. The statistics have been used to detect overlaps among YAC clones, thereby filling a gap between two neighbouring contigs and organizing overlapping rice YAC clones into contiguous fragments. We applied this method to rearranging YACs that had previously been assigned to rice chromosome 6 by anchoring with RFLP markers.

AB:   A total of 7654 DNA fragments were screened for linkage to wheat powdery mildew resistance gene Pm1c employing fluorescently based AFLP analysis and phenotypic pools from F(3) families. F(3) and derived F(4) families were used for segregation analysis. Pool screening revealed several cosegregating and tightly linked (0.9 cM) AFLP markers for the Pm1c resistance gene. The previously reported RFLP locus Xwhs178 was integrated into the AFLP map in the vicinity of Pm1c. One AFLP marker, 18M2, was determined to be highly specific for the Pm1c gene in diverse genetic backgrounds. As Pm1c allele confers an effective resistance to powdery mildew, the marker 18M2 provides a valuable tool for enhancing marker assisted selection and pyramiding of powdery mildew resistance genes in wheat.

AB:   We used PCR to obtain phylogenetically informative sequences from the high molecular weight glutenin genes of wheat. The validity of partial sequence comparisons as a means of studying glutenin phylogenetics was established by constructing neighbour-joining trees from partial alignments of 12 published glutenin allele sequences. PCR was then used to obtain 20 novel glutenin allele sequences from various Triticum and Aegilops species, including a 3000 year old preserved wheat. A neighbour-joining tree derived from all known glutenin allele sequences had eight clades, representing the eight loci from which the allele sequences were derived, and was split into two halves, one comprising alleles from the Glu-1-1 loci and the other comprising Glu-1-2 alleles. The topology was compatible with the postulated relationships between the A, B, D, and G genomes. The Glu gene duplication event was tentatively dated at 7.2-10.0 million years ago (MYA), the origin of the four genomes at 5.0-6.9 MYA, and the split between the B and G genomes at 2.5-3.5 MYA. The Glu-B1-1 alleles in cultivated wheats fell into two subgroups that diverged 1.4-2.0 MYA, suggesting that emmer was domesticated twice. The D allele sequences were relatively diverse, indicating that the hybridization event that resulted in the hexaploid bread wheats might have occurred more than once.

AB:   The genomic origin of alien chromosomes carrying resistance to wheat streak mosaic virus (WSMV) and the wheat curl mite (WCM), Aceria tosichella Keifer, was evaluated in nine wheat-alien addition, substitution, or translocation lines, derived from hybrids of wheat with Thinopyrum ponticum (Podp.) Barkworth & D.R. Dewey (2n = 10x = 70), or with Th. intermedium (Host) Barkworth & D.R. Dewey (2n = 6x = 42). One of the four wheat x Th. ponticum lines was resistant to WSMV and WCM. The other three lines were resistant to WCM, but susceptible to WSMV. Five wheat x Th. intermedium lines were susceptible to WCM, but were highly resistant to WSMV. Genomic in situ hybridization (GISH) using different genomic DNA probes demonstrated that all WSMV- and WCM-resistant lines carried an alien chromosome(s) related to the J(s) genome in Th. ponticum and Th. intermedium. The J(s) alien chromosome(s) displayed a special GISH hybridization pattern with the S genomic DNA probe, in which S genome DNA hybridized strongly in the centromeric regions and occasionally in the terminal regions with no or a weak hybridization signal in the middle of the two arms of the chromosomes. The WCM-resistant wheat x Th. ponticum lines N/5.10.10 and 63-30-2-2-2-8-1 carried the same short arm of chromosome 6J(s) derived from the partial amphiploid Agrotana, while the WSMV-resistant wheat x Th. intermedium lines T-Ai, CI15092, CI17766, A29-13-3-1 and KS93WGRC27 all had the same alien chromosome or chromosome arm of 4J(s) from Th. intermedium. The J(s) genome present in Th. ponticum and Th. intermedium is an important source of WSMV and WCM resistance that can be transferred into wheat.

AB:   Barley metaphase chromosomes (2n = 14) can be identified by fluorescence in situ hybridization (FISH) and digital imaging microscopy using heterologous 18S rDNA and 5S rDNA probe sequences. When these sequences are used together, FISH landmark signals were seen so that all 7 chromosomes were uniquely identified and unambiguously oriented. The chromosomal location of the landmark signals was determined by FISH to a barley trisomic series using the 18S and 5S probes labeled with different fluorophores. The utility of these FISH landmarks for barley physical mapping was also demonstrated when an Amy-2 cDNA clone and a BAC clone were hybridized with the FISH landmark probes.

AB:   The vrs1 (formerly v) locus in the long arm of chromosome 2H controls lateral spikelet development in barley. The vrs1 locus was mapped by backcross-derived lines that consisted of 373 BC(7)F(1) plants and 278 BC(6)F(2) plants. The linkage study indicated that MWG801, CMNA-38/700, cMWG699, vrs1 and MWG865 exist in the order listed, with map distances of 3.1, 0.4, 0.1, and 0.9 centimorgans (cM), respectively. Recombination in female and male meiocytes showed no significant difference within this region. In a neighboring region between MWG865 and MWG503, the recombination frequency was higher in female than male meiocytes in one mapping population. The combined linkage data obtained from this study were compared with published data, and genotype-specific suppression of crossing-over was not evident in the vrs1 region.

AB:   One-hundred and nineteen progeny plants of crosses between one Hordeum lechleri (2n = 6x = 42) accession and the barley varieties 'Wong' and 'Igri' comprised 54 euploids (2n = 28), 8 hyperploids (2n = 29), 46 hypoploids (2n = 22-27), and 11 polyhaploids (2n = 21). Giemsa C-banding showed most interplant chromosome variation to be caused by elimination or, more seldom, duplication of barley chromosomes. The chromosomes of 'Wong' were preferentially lost in the order, 1H-4H-5H-3H-7H-2H-6H (5-4-7-3-1-2-6); those of 'Igri' in the order, 1H-3H or 6H-7H or 5H or 4H-2H (5-3 or 6-1 or 7 or 4-2), indicating different patterns of elimination. Over years chromosome elimination may be continuous. Hypoploid genomes of 'Wong' had the chromosomes arranged in the order, 1H-5H-2H-6H-7H-3H-4H (5-7-2-6-1-3-4), with a discontinuity between chromosomes 1H(5) and 4H(4); whereas in 'Igri' the order was (1H)-5H-2H-4H-7H-6H-3H-(1H) ((5)-7-2-4-1-6-3-(5)) with a discontinuity at 1H(5), indicating varietal differences. The patterns of barley chromosome elimination may be derived from chromosome orders. Elimination starts with a chromosome at the discontinuity, continues with the chromosome at the other end of the order, and proceeds more or less alternately towards the middle. In hybrids including 'Wong', duplication affected the two chromosomes situated at either end of barley chromosome order. A few older hybrids with 2n = 21 had three or four H. lechleri chromosomes substituted for as many barley chromosomes suggesting homoeology. Our observations support the hypothesis of an orderly arrangement of the chromosomes within genomes (Bennett 1981), but they do not agree with the idea of one 'natural.
       karyotype' for each species (Bennett 1984b).

AB:   Although extensive synteny between hexaploid wheat and rice chromosomes has been demonstrated, synteny between the species breaks down in several regions of the wheat genome carrying agronomically important genes. A possible relationship between the wheat Vrn-A1, the vernalization response gene on chromosome 5A, and the rice Hd-6, a QTL controlling heading date by photoperiod response on chromosome 3, was investigated. Rice cDNA clones which had previously been mapped onto the Hd-6 region were screened for comparative genetic mapping of the Vrn-A1 region. Ten markers mapped to Hd-6 were assigned to wheat chromosome 5A by nullisomic-tetrasomic analysis. Of them, four cDNA markers, linked within 2.2 cM in the rice Hd-6 region, were mapped on the flanking region of the wheat Vrn-A1, with a complete correspondence of order, demonstrating a fine-scale genetic collinearity. These results gave evidence that the wheat Vrn-A1 region is in synteny with the rice Hd-6 region.

AB:   Iron in root plaque is usually thought to be Fe(III) because of rhizosphere oxidation. This study was conducted to examine Fe oxidation states on root surfaces of the common reed [Phragmites australis (Cav.) Trin. ex Steudel]. Using an EDTA-BPDS method, Fe(II) and Fe(III) on the surfaces of roots sampled from various environments were stabilized, extracted and determined simultaneously. The proportion of extracted Fe(II) to total Fe ranged from 0.17 to 0.65 for the roots grown in constructed wetlands, fields, and hydroponic culture; and from 0.34 to 0.70 for different sections of wetlands plant roots. The observed results suggested that De plaque is caused not only by rhizosphere oxidation, but also by Fe(II) compound formation on the root surfaces.

AB:   We hypothesized that the four rotation crops: wheat (Triticum aestivum L.), sorghum [Sorghum bicolor (L.) Merr.], lablab [Lablab purpureus (L.) Sweet] and mung bean [Vigna radiata (L.) R. Wilczek] differ in their ability to repair soil structure. The study was conducted on a Typic Haplustert, Queensland, Australia, locally termed a Black Earth and considered a prime cropping soil. Large (0.5-m depth by 0.3-m diam.) soil cores, collected from compacted wheel furrows in an irrigated cotton (Gossypium hirsutum L.) field, were subjected to three, six, or nine wet-dry cycles that simulated local flood irrigation practices. After each cycle, soil profiles were sampled for clod bulk density, image analysis of soil structure, and evapotranspiration. Generally, all crops improved soil structure over the initial field condition but lablab and mung bean gave improvements to greater depths and more rapidly than wheat and sorghum. Mung bean and lablab caused up to a threefold increase in clod porosity in the 0.1- to 0.4-m soil layer after only three wet-dry cycles, whereas sorghum required nine wet-dry cycles to increase clod porosity in only the 0.2- to 0.3-m layer, and wheat gave no improvement even after nine wet-dry cycle. Image analysis of soil structure showed that lablab and mung bean rapidly (by three wet-dry cycles) produced smaller peds with more interconnected pore space than wheat and sorghum. By nine wet-dry cycles, sorghum achieved deep cracking of the soil but the material between the cracks remained large and dense. Evapotranspiration was double under lablab and mung bean compared with wheat and sorghum. Our results indicate greater cycles of wetting and drying under lablab and mung.
       bean than wheat and sorghum that have led to rapid repair of soil compaction.

AB:   Comparisons of bulk density between no-till and chisel management systems have produced conflicting results in different studies. These conflicting results have been due to averaging across large depth increments (up to 30 cm) and by ignoring traffic patterns when sampling. A few studies have measured 2-cm depth increments for soil from tilled plots, but few, if any, have measured 2-cm incremental soil properties from no-till and compared them with similar measurements from tilled management systems. The objective of this study was to compare no-till and chisel management system effects on 2-cm increments of the vertical soil properties both for sites with and without controlled wheel traffic in corn (Zea Mays L.)-soybean [Glycine max (L.) Merr.] rotation. The controlled traffic site coated of Muscatine (Fine-silty, mixed, mesic, Aquic Hapludoll) and Tama (Fine-silty, mixed, mesic Typic Argiudoll) soils, and the site without controlled traffic had Downs soil (Fine-silty, mixed, mesic Mollic Hapludalf). We collected soil samples in 2-cm increments to the 30-cm depth. On controlled traffic plots for the 0- to 2-cm  increment, soil bulk density from no-till plots was less than from chisel plots for half of the cases, but for the 6- to 18-cm depths, soil from no-till was more dense than soil from chisel plots 61% of the time. There was no significant soil bulk density difference between tillage treatments for plots without controlled traffic. Results of tillage on residue, organic C, and crop yield were inconsistent. Chisel management did not result in less dense soil than no-till unless traffic was carefully controlled.

AB:   Nitrogen-mineralization rates are needed to accurately determine N fertilization requirements to meet plant needs while minimizing environmental contamination. A spring wheat (Triticum aestivum L.)-fallow (SW-F) system was compared with a spring wheat-winter wheat-sunflower (Helianthus annus L.) (SW-WW-SF) system on a Temvik-Wilton silt loam (fine-silty, mixed Typic and Pachic Haploborolls) at three N rates (0, 22, and 45 kg ha(-1) foe SW-F and 34, 67, and 101 kg ha(-1) for SW-WW-SF) under conventional, minimum, and no-tillage. After 10 yr, soil samples were incubated to determine N-mineralization rates. Cropping intensity, N rate, and tillage intensity interacted to affect N-mineralization rates. Within the SW-F system N-mineralization rates in 0- to 0.05-m depth were 8.2 +/- 0.8 kg ha(-1) wk(-1) in the fallow phase vs. 5.0 +/- 0.7 kg ha(-1) wk(-1) in the crop phase under conventional tillage and were 6.2 +/- 0.3 kg ha(-1) wk(-1) under minimum and no-tillage in both phases. The N-mineralization rates were 2.3 +/- 0.4 kg ha(-1) wk(-1) in 0.05- to 0.15-m depth soils of the SW-F system. In spring wheat, N-mineralization rates in 0- to 0.05-m depth soil were 9.9 +/- 0.8 kg ha(-1) wk(-1) in the SW-WW-SF system vs. 5.6 +/- 0.4 kg ha(-1) wk(-1) in the SW-F system and in the 0.05- to 0.15-m depth were 3.6 +/- 0.1 kg ha(-1) wk(-1) in the SW-WW-SF system vs. 2.4 +/- 0.2 kg ha(-1) wk(-1) in the SW-F system. Within the SW-WW-SF system, N-mineralization rates in the 0- to 0.05-m soil layer were 6.8 +/- 0.5 kg ha(-1) wk(-1) under winter wheat vs. 9.9 +/- 0.8 kg ha(-1) wk(-1) under spring wheat and 9.2 +/- 0.6 kg ha(-1) wk(-1) under sunflower. In the 0.05- to 0.15-m soil layer, N-mineralization rates were 3.3.
       +/- 1.0 kg ha(-1) wk(-1). More intensive cropping and conservation tillage increased N-mineralization rates in this soil and may ameliorate the decline in N fertility associated with crop-fallow systems.

AB:   Continuous cropping or decreasing the frequency of summer fallow (F) in cereal-based dryland rotations may have benefits other than greater water utilization and erosion control. We hypothesized that rotations with no fallow or minimum fallow frequency can produce more biomass and cover than the traditional winter wheat (Triticum aestivum L.)-summer fallow systems (W-F), and ultimately, greater amounts of soil organic matter (SOM). To this end, we evaluated changes in various pools of SOM at the 0- to 5- and 0- to 15-cm depths on a Weld loam (fine, smectitic, mesic aridic Paleustolls) that were caused by (i) decreasing fallow or increasing cropping intensities, (ii) specific rotations of the same length but with different crop sequencing, and (iii) accumulated residue and roots from reduced- or no-tillage from 1993 to 1997. Total soil organic carbon (SOC) and N for the 0- to 5-cm depth increased by approximately equalt to 20% with continuous cropping rotations compared with W-F rotations. Particulate organic matter-carbon (POM-C) doubled, while POM-N, and soluble organic C (OC) increased by one third for the same comparison. At the 0- to 15-cm depth, SOC, POM-C, and POM-N did not differ among systems with fallow, nor among systems with cropping intensities greater than W-F. Thus, significant differences always existed between W-F and continuous cropping. Generally, fallow had a negative influence on SOC accumulation, and continuous cropping a positive influence on surface SOM. Changes in SOC did not correlate with yields in the five-year comparison of this ongoing study.

AB:   Cycling of N through an agroecosystem can be managed more effectively if effects of N management and cropping sequence on soil N microbial processes are understood. Effects of cropping intensity and N fertilizer rate on net soil N mineralization were studied as well as their correlation with precipitation, air temperature and soil water content. Net soil N mineralization was measured by incubating undisturbed soil cores (15-cm depth) containing anion and cation exchange resins at their bottoms. Cores were incubated during each of five time periods (3-4 wk each) during the fallow phase (mid-April to mid-September) of two no-till cropping systems, wheat (Triticum aestivum L.)-fallow (WF) and wheat-corn (Zea mays L.)- fallow (WCF). Past N fertilizer applications were over four rates with total amounts applied during the previous 6 yr of 0, 95, 190, and 286 kg N ha(-1) in WF and 0, 134, 269, and 403 kg N ha(-1) in WCF. Soils were an Aridic Paleustoll at Sterling and an Aridic Argiustoll at Stratton in eastern Colorado. Total net N mineralization in WCF was half that in WF (22 vs. 43 kg N ha(-1); 2-site average), probably due to greater immobilization as evidenced by nearly three times greater accumulation of crop residue on the soil surface after 6 yr of no-till management. Greater conservation of applied N and soil N can be expected in the more intensive WCF system. Total mineralized N increased with N rate by approximately equal to 0.2kg ha(-1) for each kg ha(-1) of previously applied N. Precipitation in combination with air temperature and their interaction term gave the best prediction of average daily N mineralization at both sites.

AB:   Rice (Oryza sativa L.) genotypes with a high ability to support biological N(2) fixation are of interest because they would enhance N gains in the rice-soil system without changing existing cultural practices. Pot experiments were conducted in a greenhouse during the 1994 wet season to determine the amount of N(2) derived from the atmosphere (Ndfa) by 10 rice genotypes grown in three soils with varying levels of initial soil-NH(4)(+)-N. Enriched (15)N and natural abundance delta(15)N dilution methods were employed. Flooded soils were puddled with and without 99.5 atom (15)N%-labeled urea to minimize spatial variation of the isotope. The integrated (15)N enrichment of plant available N, calculated using a model that accounts for temporal changes in the isotopic composition, was used as a reference to estimate genotypic differences in Ndfa. The (15)N enrichment of soil available N declined exponentially and was half the original level at 122d. The delta(15)N values correlated with atom (15)N% excess of enriched (15)N for the rice genotypes grown in two out of three soils. Percentage Ndfa for the genotypes across three soils ranged from 4.2 to 32.2 when calculated using as a reference plant, and from 10.8 to 35.9 when calculated using (15)N enrichment of soil available N as a reference. Genotypic differences were significant and more pronounced at low soil-NH(4)(+)-N (11 mg kg(-1)) than at higher soil-NH(4)(+)-N (79 and 92 mg kg(-1)); they ranged from 14.9 to 35.9% at low N and from 10.8 to 23.6% at high N. Some genotypes consistently gave either high or low Ndfa. Because of the low levels and narrow range of genetic differences in associative N(2) fixation, the.
       potential for its improvement through breeding appears to be limited.

AB:   Fumonisins are produced by several fungal species that are common contaminants of maize. The most abundant naturally occurring fumonisin, fumonisin B1 (FB1), has been shown to induce several animal disease syndromes. The development of analytical methods is therefore important. A new method is described that integrates extraction and purification of maize samples in one step. It efficiency is compared against well-known methods, and shows similar results for naturally contaminated maize. It is concluded that the proposed method can be applied to fumonisin B1 and fumonisin B2 (FB2) analysis in maize at least within the concentration range found.

AB:   Unusual wet and cool weather conditions during the 1994 growing season in Maryland and Delaware resulted in a severe outbreak of Fusarium graminearum on sweet corn ears ('Moore' variety') prior to harvesting and canning. The number of ears visibly infected with Fusarium spp. ranged from less than 5% to 25% in some fields. Injection typically occurred at the tassel end of the ears. Fusarium graminearum was isolated from surface disinfected kernels, both those which were visibly infected and those kernels which appeared disease-free in an area up to 5 cm from the edge of the visibly moulded areas. Infected ears were cut into four sections and the kernels only were analysed for deoxynivalenol (DON) using liquid chromatography (LC) and mass spectrometry/gas chromatography (GC/MS). Kernels from the visibly mouldy area of the ears contained DON at levels of approximately 446 mg/g DON on average; whereas in the nonvisibly infected portion of the ears adjacent to the mouldy tips, DON levels averaged approximately 10 mg/g. Sections of ears closest to the base contained no detectable DON or less than 1 microgram/g. This is the first reported natural occurrence of the mycotoxin DON in sweet corn prior to harvest and canning.

AB:   The potential use of faecal n-alkanes for estimation of intake and diet composition over periods of 1-2 days was assessed in two experiments. The aim was to determine the accuracy with which intake and diet composition could be estimated by characterizing faecal excretion of n-alkanes following a discrete dose as opposed to steady state kinetics used in previous work. In the first experiment, 16 sheep were fed mixtures of spinach (rich in C31-alkane) and cabbage (rich in C29-alkane) in known proportions and amounts for two days. Artificial n-alkanes (C28- and C32-alkane) were dosed on four occasions during this time. Total intakes were controlled at 0.2, 0.3, 0.4 or 0.5 kg dry matter (DM) per day and nominal amounts of spinach offered (as a proportion of the total diet) were 0.00, 0.15, 0.30 and 0.45. Each sheep received a unique combination of intake and dietary proportions (four intake rates x four proportions). Sheep were fed fresh grass (timothy, Phleum pratense) before and after feeding spinach and cabbage. Sequential rectal grab samples of faeces were collected at regular intervals and total faecal collections were carried out over 144 h from the start of the spinach/cabbage feeding period to obtain samples for n-alkane analysis. In the second experiment, fresh grass was sprayed with two combinations of artificial n-alkanes (C24- and C32- or C28- and C36-alkane) and fed to 16 sheep over a 24 h period. Each sheep received one of four intake rates (0.8, 1.0, 1.2 or 1.4 kg DM/day) and, within intake rates, each sheep received one of four different proportions of the herbage sprayed with the combinations of n-alkanes (0.2, 0.4, 0.6 or 0.8), in a similar fashion.
       to the first experiment. In order to estimate intake, C26- and C34-alkanes were dosed at the start of the feeding period. Faecal sampling procedures were the same as those in the first experiment. Different parameters of faecal excretion curves of dosed and natural n-alkanes were used to estimate dietary proportions and intake. Parameters tested included area under the excretion curve and curve maximum. Dietary proportions were calculated using an iterative minimization procedure employing faecal and herbage n-alkane concentrations. Intakes were estimated using ratios of dosed:natural faecal n-alkanes. The best estimates of dietary proportions were obtained using faecal concentrations at a single point in time in both experiments (> 80% variation explained for regressions of estimated v. actual proportions). Intake estimates required the calculation of the area under the excretion curve to obtain acceptable estimates (70-90% variance explained for regressions of estimated v. actual intakes in Expt 2). The experiments demonstrate that precise estimates of diet composition can be obtained using single faecal samples following consumption of simple herbage mixtures over 24-48 h. Intake may also be estimated using this technique provided that a series of faecal samples are collected over 4-5 days following the period of ingestion.

AB:   Nitrogen (N) inputs and outputs were measured over 3 years in a trial with four farmlets (each with 16 randomly-allocated 0.4 ha paddocks) on permanent white clover/ryegrass pastures which were grazed throughout the year by dairy cows near Hamilton, New Zealand. Three farmlets were stocked at 3.3 cows/ha and received nominal rates of N fertilizer (urea in 8-10 split applications) of 0, 200 or 400 kg N/ha per year. A fourth farmlet with 4.4 cows/ha received 400 kg N/ha per year and was supplemented with maize grain during the first two years. Nitrogen balances were calculated, with sigma N inputs approximately sigma N outputs. Annual inputs from N2 fixation were 99-231 kg N/ha in the 0 N farmlet, but declined to 15-44 kg N/ha in the 400 N farmlets. The main N outputs (in kg N/ha per year) were in milk (72-126), nitrate leaching (20-204), and transfer of N via cow excreta from pastures to lanes and milking shed (54-92). Gaseous losses by denitrification (3-34) and volatilization (15-78) were smaller than the other N outputs but increased significantly with N fertilizer application. In the maize-supplemented farmlet, N outputs in milk were 31% higher than in the corresponding non-supplemented 400 N farmlet, whereas leaching losses averaged 17% lower during the 2 years of supplementation. In the N-fertilized farmlets, estimated N balances were influenced by inclusion of the transitional N processes of immobilization of fertilizer N into the soil organic N pool (estimated using 15N at 42-94 kg N/ha per year) and the contribution from mineralization of residual clover-fixed N in soil not accounted for in the current estimates of N2 fixation (estimated at up to 70% of measured N2.
       fixation or 46 kg N/ha per year). However, these processes were counteracting and together were calculated to have only a small net effect on total N balances. The output of N in products (milk, meat and feed) relative to the total N input averaged 26% in the 400 N farmlets, and is compared to that measured for commercial intensively-managed dairy farms in England and the Netherlands (14-20%). The 0 N farmlet, which was reliant on N2 fixation as the sole N input, was relatively very N-efficient with the milk production being 83% of that in the 400 N farmlet (at 3.3 cows/ha) and the N output in products relative to total N input averaging 52%.

AB:   In order to learn more about the feeding value of stovers and straws, seven diets were compared in one experiment and nine in another. The diets in the first experiment were: the upper and lower parts of lucerne (Medicago sativa) hay, the leaves, upper stem and lower stem of maize (Zea mays) stover and the leaves and stem of sorghum (Sorghum vulgare) stover. The diets in the second experiment were: the upper and lower parts of lucerne hay, the leaves, stem and whole stover of millet (Setaria italica), the straw and chaff of wheat (Triticum aestivum), rice (Oryza sativa) straw and sweet potato (Ipomoea batatas;) haulm. The diets were fed to sheep to record rate of intake, voluntary intake and in vivo digestibility. The diets were analysed for cell wall (as neutral detergent fibre), crude protein and lignin. Organic matter degradation and cell wall degradation were recorded in nylon bags in the rumen of cattle. The highest rates of intake (6.8-9.6 g dry matter/min) and voluntary intake (75-103 g dry matter/kg W0.75/day) were with sweet potato haulm and the upper, leafy part of lucerne hay. The voluntary intake of millet leaves, wheat chaff and the lower, stemmy part of lucerne hay was moderately high (46-70 g dry matter/kg W0.75/day). Voluntary intake of leaves was higher than that of stems in the case of millet, sorghum and to a lesser extent maize. The lowest rates of intake were with millet stem, sorghum stem and rice straw (1.8-2.4 g dry matter/min). In vivo digestibility of organic matter was highest (59-67%) for the upper part of lucerne hay, sweet potato haulm, the lower part of maize stem and millet leaves. The leaves of maize were less digestible than the stem, while the reverse.
       was the case with millet. Cell wall content was particularly high (74-78% of dry matter) in millet stem, wheat straw and chaff, rice straw and sorghum stem. Lignin content was low (3.6-4.2% of dry matter) in millet leaves, maize leaves and the upper part of maize stem. Organic matter degradation after 24 h incubation in the rumen was highest (80%) in sweet potato haulm and lowest (39-44%) in millet stem, wheat straw and chaff and rice straw. Cell wall degradation after 96 h in the rumen was highest (76-81%) with the leaves of maize, sorghum and millet and lowest (40-59%) with lucerne hay, millet stem and stover, wheat straw and chaff and rice straw.

AB:   The potential for using crop wastes as a source of nutrients on the yields of rice grown under submerged conditions was studied in both field and pot experiments at the Experimental Farm of the Agricultural and Food Engineering Department, Indian Institute of Technology, Kharagpur during 1992/93 and 1993/94. The application of groundnut haulm at 3.0 t/ha, maize stover at 5.0 t/ha, mustard stover at 3.0 t/ha and green manure at 1.5 t/ha contributed considerable amounts of nutrients, which improved components of yield, yield and nutrient uptake by rice and also improved the organic carbon (OC) content and available N, P and K in the soil. Yields and soil fertility were both further improved when these organic materials were combined with inorganic fertilizer to supply the recommended amounts of nutrients, except that inorganic fertilizer alone did not cause an increase in the OC content of the soil. In the pot experiment, the production of NH4-N and NO3-N was both larger and more consistent when organic and inorganic nutrient sources were added together than when inorganic sources alone were used.

AB:   A comprehensive study was conducted over a 4-year period (1984-87) to evaluate the water use, growth and yield responses of pearl millet (Pennisetum glaucum (L.) R. Br.) cv. CIVT grown with and without fertilizer (30 kg P2O5 and 45 kg N ha-1) at the ICRISAT Sahelian Centre, Sadore, Niger. Our study showed significant year and fertilizer effects on the growth and yield of millet at the study site. Observed year effects were primarily due to the variations in the amount and distribution of rainfall in relation to the potential demand for water. During 1984, 1985 and 1987, total rainfall was below the long term average, while in 1986 it was above average. While the onset of rains (relative to the average date of onset) was early from 1984 to 1986, in 1987 the sowings were delayed by as much as 33 days. Of all the four years, the separation between the treatments in the cumulative evaporation is most evident for 1984, which was a drought year with below-average rainfall in all the months from June to September. Cumulative evaporation patterns in 1985 and 1986 were similar because of regular rains and high average rainfall per rainy day from June to October. In 1987, sowings were delayed until 15 July and only 6.9 mm of rainfall was received per rainy day in July. Hence cumulative evaporation was initially low and showed a significant increase only after two significant rain events in early August. There was a large response to fertilizer in all the years as small additions of fertilizer phosphate increased the soluble phosphate in the soil. Fertilizer application resulted in a small increase in water use (7-14%) in all years except 1987. Increased yield due to the application of fertilizer.
       was accompanied by an increase in the water-use efficiency (WUE) in all the four years with the largest increase in 1985. The beneficial effect of fertilizers could be attributed to the rapid early growth of leaves which can contribute to reduction of soil evaporative losses and increased WUE. Over the four seasons, average increase in the WUE due to the addition of fertilizer was 84%.

AB:   Soil sampling in autumn gives important information on the soil N dynamic. In the growing seasons 1991/92 to 1995/96, the effects of different crop management systems on soil mineral N (NO3-N plus NH4-N:N(min) were investigated in a factorial field experiment at Hohenschulen Experimental Station near Kiel in NW Germany. The crop rotation was oilseed rape--winter wheat--winter barley, and soil tillage (conservation tillage without ploughing, conventional tillage), application of pig slurry (none, autumn, autumn + spring), mineral N fertilization (0, 120 and 240 kg N ha-1) and fungicide application (none, three applications) were all varied. Each year, the treatments occurred in all three crops of the rotation and were located on the same plots. N(min) was determined on four dates ('After drilling', 'End of autumn growth' before winter, 'Beginning of spring growth' before N fertilizer application, and 'After harvest') to 90 cm in 30 cm horizons. Under all crops, N(min) showed a large year to year variation. Highest values of 132 kg N ha-1 were observed 'After drilling', which decreased until 'End of growth'. The increase of autumn N(min) ('After drilling', 'End of autumn growth') was mainly due to autumn slurry, whereas mineral N fertilizer mainly affected N(min) 'After harvest'. Soil tillage and fungicide application only slightly modified N(min) at all dates. The relationship between N leaching and N(min) measured either 'After drilling' or at the 'End of autumn growth' in 1991/92-1994/95 remained too poor to be used to estimate N leaching. N net mineralization during autumn and winter varied with crops, as estimated by the N(min) changes between 'After drilling' minus.
       'Start of spring growth' plus N uptake by the crop at 'Start of spring growth' plus N leaching during winter. On average over the years, 39 kg N ha-1 were mineralized under oilseed rape and 42 kg N ha-1 under wheat compared with 31 kg N ha-1 under barley. However, a large year-to-year variation occurred. In addition, the ranking of the years differed with the crops. Slurry application led to different amounts of mineralized N. Under barley only 25 kg N ha-1 were calculated for the autumn slurry, but 42 kg N ha-1 for the autumn plus spring slurry treatment. In contrast, under oilseed rape the highest value of 41 kg N ha-1 occurred in the autumn slurry plots. Under wheat, slurry application only slightly affected N mineralization. Increased mineral N fertilization decreased N release under oilseed rape, but significantly increased it under cereals. Application of fungicides did not affect N mineralization during winter.

AB:   A review of applications of finite element techniques in the calculation of stress distributions in grain kernels during moisture desorption and adsorption is given. In the analysis presented in this paper, the rice kernel was assumed to be a linear viscoelastic ellipsoid body. The model simulated the expansion of the rice kernel and evaluated the magnitude of the local strains and stresses. The finite element method was used to obtain a numerical solution to the stress-strain relationship. For determining fissure initiation and propagation, the failure criterion based on local strain energy density of distortion was used. For stress analysis the maximum or ultimate tensile strength criterion was used. Simulations resulting from the model were compared with the experimental results.

AB:   Acidification of cattle slurry with nitric acid to pH 4.5 was studied on experimental dairy farms in the Netherlands as a measure to reduce ammonia losses. This paper presents the results of two field experiments, carried out to assess the utilization of nitrogen (N) from nitric acid treated cattle slurry following surface application to grassland. Three aspects were studied: (i) the utilization of N from nitric acid treated cattle slurry following a single surface application to grassland: (ii) the effects of multiple applications of nitric acid treated cattle slurry on N utilization, residual inorganic N in the soil and sward quality: and (iii) the residual effects of nitric acid treated slurry on DM and N yield. In these experiments undiluted acidified slurry (UAS) and diluted acidified slurry (DAS) were compared with calcium ammonium nitrate (CAN). Apparent N recoveries (ANR) and apparent N efficiencies (ANE) were calculated on the basis of inorganic N in applied fertilizer and slurries. Following single applications of UAS and CAN on the sward on the clay soil, the average ANR values of UAS and CAN were 0.74 and 0.75 kg kg(-1), respectively. The average ANE values of UAS and CAN were 30.3 and 29.5 kg DM per kg N, respectively. Single applications of DAS and CAN on the sandy soil resulted in average ANR values of 0.65 and 0.84 kg kg(-1) and average ANE values of 24.1 and 29.2 kg DM per kg N for DAS and CAN, respectively. On average, the direct ANR values after four successive applications of CAN, UAS or DAS were 0.82, 0.82 and 0.74 kg kg(-1), respectively and the direct ANE values were 28.4, 27.8 and 27.0 kg DM per kg N. On the sandy soil, the amount of residual.
       inorganic N in the soil after the 4th cut increased with increasing rates of inorganic N application, with a slightly higher amount on plots treated with acidified slurry than on plots fertilized with CAN. On the clay soil, the amount of residual inorganic N was not affected by N application rate nor N source. On average, the residual ANR values, in the unfertilized 5th and 6th cuts, of CAN, UAS or DAS were 0.08, 0.10 and 0.09 kg kg(-1), respectively and the residual ANE values were 2.7, 3.3 and 3.0 kg DM per kg N. It was concluded that nitric acid treated cattle slurry is an effective N fertilizer on grassland and that the residual effect of nitric acid treated cattle slurry is only marginally higher than that of CAN. Repeated applications of nitric acid treated cattle slurry did not affect sward composition.

AB:   A field study using 15N was conducted on a Vertisol in semi-arid Morocco to assess the fate and efficiency of fertiliser N split applied to winter wheat (Triticum aestivum L.). Splitting of fertiliser N is highly crucial in semiarid regions, considering the increased moisture stress towards the end of the growing season. A N fertilisation rate of 100 kg N ha(-1) was split according to two schemes: i) 25% at planting, 50% at tillering and 25% at stem elongation; or ii) 50% at tillering and 50% at stem elongation. The application of 100 kg N ha(-1) increased the vegetative dry matter production with more than 2000 kg dry matter ha(-1) in comparison with the control treatment. Nitrogen fertilisation had no significant effect on the grain yield production. Moreover, the 1000 grain weight decreased from 32 to 26 g due to N fertilisation. Total N uptake was about 50 kg N ha(-1) higher for the fertilised plants in comparison with the unfertilised plants, but it was not affected by the splitting pattern of the fertiliser N. Recoveries of 15N-labelled fertiliser by the plant (above-ground plant parts plus roots from the upper 20 cm layer) were low (31% and 24% for the 3-split and 2-split application, respectively). More N in the plant was derived from fertiliser when applied early in the growing season than when applied late in the season. About 13% of the N in the plants was derived from the 50 kg N ha(-1) at tillering, while only 5% was derived from the N application (50 kg N ha(-1) at stem elongation. At harvest, a high residual of fertiliser-derived N was found in the 0-90 cm profile (62% and 72%, for the 3-split and 2-split application, respectively). Less than 10% of the applied N could not.
       be accounted for, the amount being highest for the application at tillering. This N not accounted for was mainly ascribed to denitrification after an important rainfall event. The application of fertiliser N led to an increase of about 20 kg N ha(-1) in soil N uptake by the crop (positive ANI). The results suggested a dominant influence of moisture availability on the fertiliser N uptake by wheat.

AB:   Phosphorus fixation results in low P use efficiency in acid soils. Increase in soil pH through urea hydrolysis may improve P availability and use efficiency. Growth chamber and field experiments were conducted to evaluate effects of urea on triple superphosphate (TSP) transformation and P use efficiency. A Ste. Rosalie clay (Typic Humaquept), an Ormstown silty clay loam (Typic Humaquept) and a Chicot sandy clay loam (Typic Hapludalt) were used in the growth chamber experiment with three rates of N (0, 200 and 400 mg N kg(-1)), two N sources, either urea or NH4 NO3, based on 87 mg P kg(-1) soil. In the field, three rates of urea (0, 60 and 120 kg N ha(-1)) and two rates of TSP (26 and 52 kg P ha(-1) were compared on a Ste. Rosalie clay and an Ormstown silty clay loam. Compacted or blended mixtures of urea-TSP with different ratios of N:P were used in the field experiment. In the growth chamber experiment, soil pH and dissolved organic carbon (DOC) concentration was increased by added urea, and Mehlich (3) and water extractable P thus increased with increased urea. Soil pH, DOC and available P levels were not significantly affected by added NH4 NO3. Phosphorus uptake increased with added N, either urea or NH4 NO3, but P concentration increased only with addition of urea. In the field, soil Mehlich (3)-P at day 20, P uptake and use efficiency, corn yields increased when urea was applied with TSP. Compacted mixtures of urea-TSP increased P uptake and use efficiency, corn yields in comparison with blended mixtures. The beneficial effects of banded urea with TSP on P availability and P use efficiency were primarily attributed to urea hydrolysis, subsequent pH.
       increase and organic matter dissolution as well as synergistic effect of N and P. These results indicate that compaction of urea plus TSP may offer a significant advantage over blended mixtures.

AB:   Methane emissions from flooded rice grown under greenhouse conditions were monitored using a closed chamber technique. The three rice cultivars showed similar diel emission patterns though the amplitudes differed. Variation in emissions maximum emission rate from the different cultivars ranged from 0.164-0.241 mg/pot/h at tillering stage, 0.714-2.334 mg/pot/h at heading stage, 0.399-1.393 mg/pot/h at ripening stage. The methane emissions increased in the morning at accelerating rates, reached a maximum in the early afternoon, then decreased rapidly to constant rates during the night. The diel emission pattern was modeled a Gaussian equation for daytime, and a constant for nocturnal emissions. Applying an Arrhenius equation, more than 90% of the diel variation of methane emissions could be predicted from soil temperature fluctuations. The predictions improved by using a diffusion model based on soil temperature and dissolved methane concentrations in soil solution. Soil temperature and methane concentration in soil solution are the two major factors control line diel methane emissions.

AB:   The recovery of soil mineral nitrogen N by crops, and its subsequent utilisation for dry matter (DM) production may be increased when the application of N is postponed until after crop emergence. The significance of this strategy for silage maize was studied in nine field experiments on Dutch sandy soils from 1983 to 1988. In five experiments the effect of slurry applied before planting at a rate of circa 66 m3 ha(-1), was compared to the effect of a similar rate of which half was applied before planting and half at the 4-6 leaf stage. In the 4-6 leaf stage slurry was either injected or banded. In four other experiments the effect of mineral fertilizer-N splitting was studied. In these experiments, 30 m3 ha(-1) cattle slurry, applied before planting, was supplemented with mineral fertilizer-N at rates ranging from 40 to 160 kg ha(-1), either fully applied before crop emergence or split. When split, 40 kg ha(-1) of the mineral fertilizer-N rate was banded at the 4-6 leaf stage. According to balance sheet calculations, substantial losses of slurry N and mineral fertilizer-N occurred during the growing season. Losses were compensated for, however, by apparent mineralization, ranging from 0.34 to 0.77 kg N ha(-1) day(-1). Split applications of cattle slurry had a significant positive effect on the DM yield in two out of five experiments compared to the conventional non-split application, but only when the post-emergence slurry application was banded which is no longer in accordance with present legislation. Split applications of mineral fertilizer-N had a significant positive effect in one experiment where rainfall was excessive but not in the others. The results provide insufficient.
       evidence to recommend farmers to split applications. Soil mineral N sampling at the 4-6 leaf stage should hence be considered a control on the appropriateness of early N applications after exceptional weather conditions rather than a routine observation on which the post-emergence N dressing is to be based in a deliberate splitting strategy. Our data suggest that the financial return of a 40 kg ha(-1) supplementation with mineral fertilizer-N, was questionable when more than 175 kg N ha(-1) were found in the upper 0.6 m soil layer at the 4-6 leaf stage.

Applied urea was completely hydrolysed in 12.8 and 6 days in unamended, green manure and wheat straw amended soil respectively. By applying 0.5% (w/w of urea) NBPT, complete hydrolysis of urea was delayed up to 16 days in the unamended soil, whereas in wheat straw amended soil urea hydrolysis was completed by the 12th day even when it was treated with 2% NBPT. Applied at 1 or 2% level, NBPT delayed the NH3 volatilization to the 4th day after application of urea in green manure or wheat straw amended soil. Hydrolysis of urea was more effectively retarded by applying NBPT in the unamended soil than in soil amended with green manure or wheat straw. In the unamended soil, 7.1% of the applied urea was lost through NH3 volatilization. The losses were reduced to 1.2 and 0.7% by applying 0.5 and 1% NBPT, respectively. Enhanced NH3 volatilization caused by the green manure or wheat straw was counteracted by applying NBPT.

AB:   Glutathione S-transferases (GSTs) are involved in detoxification of a wide variety of electrophilic compounds including herbicides. Several corn isoforms (GSTs) have been studied for their ability to conjugate these substrates with reduced glutathione (GSH). Three cDNAs, encoding corn GST subunits of 29, 27, and 26 kDa, respectively, were cloned into expression systems in Escherichia coli. N-terminal 6xHis-tagged recombinant GST isoforms I, II, III, and IV were purified with nickel-nitrilotriacetic acid (Ni-NTA) metal-affinity chromatography and were analyzed biochemically. As the corn enzymes, each recombinant GST isoform also consists of two subunits. Using three different GST-substrates, recombinant isoforms showed similar substrate specificities as natural corn GSTs. Some GST isoforms may be involved in the defense response to oxidative stress in plants. Besides standard GST activities, inactivation of endogenous, toxic alpha,beta-unsaturated aldehydes was measured. Furthermore two recombinant GST isoforms (GST II and GST IV) showed high glutathione peroxidase activity using three different organic hydroperoxides as substrates. Apparently, GST isoforms including the 27-kDa subunit show glutathione peroxidase activity.

AB:   The aim of this study was to investigate the mechanism of photosynthetic changes in sugarcane leaves in response to chilling temperature by using three species (Saccharum sinense R. cv. Yomitanzan, Saccharum sp. cv. NiF4 and Saccharum officinarum L. cv. Badira) differing in origin and cold sensitivity. Yomitanzan is native to subtropical areas, Badira is native to tropical areas and NiF4 is a hybrid species containing genes of both tropical and sub-tropical species. At exposure to chilling temperature (10 degrees C), the photosynthetic rate in the leaves at either 10 degrees C or 30 degrees C showed a greater decrease in Badira than in NiF4 and Yomitanzan. After 28 h exposure of plants to the chilling temperature, the extractable activities of pyruvate, orthophosphate dikinase (PPDK) and NADP-malate dehydrogenase (NADP-MDH) increased or were relatively stable in the leaves of NiF4 and Yomitanzan, but decreased substantially in Badira. Correspondingly, there was a substantial accumulation of aspartate, and the level of alanine increased in Badira leaves during the chilling treatment. It is suggested that NADP-MDH and PPDK are key enzymes which may determine the cold sensitivity in photosynthesis of sugarcane.

AB:   High temperatures during reproductive development alter kernel development and reduce yield and quality in wheat (Triticum aestivum L.). Understanding how temperature alters kernel formation will help the development of genetic approaches to enhance heat tolerance in this cereal. A relationship between kernel development and postanthesis cytokinin accumulation is well documented, but the effect of temperature on this relationship is not known. This study quantified the effects of a postanthesis temperature treatment (7 d at 35/25 degrees C day/night) on kernel development and cytokinin accumulation in a soft white winter wheat (c.v. Stephens). Kernels from control plants maintained at 25/15 degrees C accumulated zeatin, dihydrozeatin and their corresponding 9-ribosides from 1 to 4 d postanthesis. Postanthesis kernel cytokinin accumulation was reduced by 50-80% by the temperature treatment. Kernel cytokinin content in control plants declined to baseline by 5 d postanthesis and remained at that level. Kernels from treated plants had a secondary peak of cytokinin accumulation 6-8 d after anthesis. This treatment significantly reduced kernel weight. The magnitude of the effect on kernel number was smaller than on kernel weight, but was statistically significant. Reduced kernel weight was accompanied by reduced cytokinin accumulation. Exogenous cytokinins did not mitigate the temperature effects on kernel weight, but at the highest concentrations, did reduce the effect on kernel number.

AB:   DNA sequences of the chloroplast gene ndhF were used to estimate the phylogeny of the grass tribe Andropogoneae. Previous hypotheses of relationships in the tribe were based on cytological and morphological characters such as the presence/absence of awns, monoecy vs. andromonoecy, or inflorescence characteristics. Classifications were subsequently proposed based on those ideas of relationships, and these are examined in the context of the molecular data. The notion that the base number of the tribe is x=5 is tested using the phylogeny. Diploids with n=5 are not conclusively the earliest diverging members of the group, but are nested high in the tree and the earliest diverging lineages in the tribe have n=10. Subtribal designations are not informative due to the lack of resolution between clades in the strict consensus tree. There are well-supported clades in the tribe, including three Sorghum lineages and a "core" Andropogoneae clade, even though relationships among clades are poorly supported. The topological pattern suggests a rapid radiation for the group. A preliminary assessment of the generic limits of the genus Sorghum show it to be paraphyletic, including the genera Cleistachne, Miscanthus, and a species of Microstegium. Subtribe Sorghinae is represented here by Sorghum, Sorghastrum, Cleistachne, Bothriochloa, Capillipedium, Dichanthium, and Chrysopogon and does not form a monophyletic group.

AB:   A potato and wheat flour blend was processed in a twin-screw extruder at different moisture contents (16-21%) and screw speeds (200-400 rpm). The effect of these extrusion variables on the pasting behaviour of extruded products was studied, using a rapid visco analyser (RVA). The viscosity-related parameters determined include initial peak viscosity, cold paste viscosity and breakdown viscosity. Moisture content of the feed had a dominating effect compared to that of the screw speed of the extruder; an increase in moisture increased the aforesaid viscosity-related parameters. High moisture content of the blend changed the pasting characteristics of the extruded material to a great extent when the screw speed was between 200 and 300 rpm. The net specific mechanical energy was negatively related (p < or = to 0.05) to the viscosity-related parameters.

AB:   Rheochloa scabiflora Filg., P.M. Peterson & Y. Herrera, gen. et sp. nov., is described and illustrated. The new species occurs in humid grasslands of Municipio de Mineiros, Goias, Parque Nacional das Emas in central Brazil. It seems most closely allied with Dinebra but differs by its perennial habit, inflorescences composed of 3-5 subdigitate racemes, short pedicellate spikelets, glabrous lemmas that are ciliolate on the apex, and fusiform caryopses with persistent style bases. Rheochloa is tentatively placed in subtribe Eragrostidinae of tribe Eragrostideae. So far, R. scabriflora is known only from a single population located inside Parque Nacional das Emas (18 degrees 17'55"S-52 degrees 43'79"W).

AB:   Seed yield response of cool-season grasses to spring-applied N is usually limited because of lodging. This study investigated whether chemical dwarfing of these crops improves their seed yield response to spring-applied N. Chewing's fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman; syn. F. rubra var. commutata Gaudin], tall fescue (Festuca arundinacea Schreb.), and orchardgrass (Dactylis glomerata L.) were established in September 1983 near Corvallis, OR. Treatments were all combinations of 90, 120, 150, 180, and 210 kg N ha(-1) applied at the double-ridge stage of development, followed by paclobutrazol [(2RS,3RS)-1-(4-chlorophenyl)-4,4- dimethyl-2-(1H-1,2,4- triazol-1-yl)-pentan-3-ol] at 0, 0.25, 0.5, and 1 kg a.i. ha(-1) applied at floret initiation stage in 1985 and 1986. Averaged across years and N rates, the 1 kg ha(-1) rate reduced Chewing's fescue height by 23% and tall fescue and orchardgrass heights by 30%. In the absence of paclobutrazol, Chewing's fescue and tall fescue seed yields were the greatest at 90 kg N ha(-1). Paclobutrazol did not affect seed yield response of Chewing's fescue to N rates, but tall fescue seed yield in 1986 was the greatest at 150 kg N ha(-1) when only 0.25 kg a.i. paclobutrazol ha(-1) was applied. Averaged across N  rates, the 0.5 kg ha(-1) rate increased Chewing's fescue seed yield by 32% in 1985 and 18% in 1986, and also increased tall fescue seed yield by 32% in 1985 and 23% in 1986. Orchardgrass seed yield was the greatest at 180 kg N ha(-1) in both years. Paclobutrazol did not affect orchardgrass seed yield in 1985, and the 1 kg ha(-1) rate decreased seed yield in 1986. We concluded that in western Oregon paclobutrazol.
       application at floret initiation does not improve seed yield response of these crops to spring-applied N, but it would significantly improve Chewing's fescue and all fescue seed yield, regardless of the N rate applied. Results did not indicate any advantage for applying paclobutrazol on orchardgrass seed crop.

AB:   Understanding effects of spring N rates and application timing on seed yield and yield components of cool-season grass seed crops will help improve N fertilization management. We tested effects of 90, 120, 150, 180, and 210 kg N ha(-1), applied at the double-ridge (DR) stage of development on seed yield and yield components of Chewing's fescue [Festuca rubra L. subsp. fallax (Thuill.) Nyman; syn. F. rubra var. commutata Gaudin], tall fescue (F. arundinacea Schreb.), and orchardgrass (Dactylis glomerata L.) in 1985 and 1986. In a second study, effects of 120 kg N ha(-1), applied either at DR, at spikelet initiation (SI), or equally split between the two stages, were tested. Soil type for both experiments was fine-silty, mixed, mesic Aquultic Argixerolls. Chewing's fescue seed yield was not affected by N rates in 1985 and was the greatest at 90 kg N ha(-1) in 1986. Averaged across years, orchardgrass seed yield was the greatest at 120 kg N ha(-1). Nitrogen rates did not affect seed yield of tall fescue. Seed yield of all species was most closely correlated with the number of seeds produced per unit area. Seed number per unit area was primarily correlated with the number of seeds produced per panicle in all species; in orchardgrass, the number of panicles per unit area also contributed to total number of seeds produced. Seed yields of all three species were the greatest when N was applied at DR. Split application was not better than application of all N at DR or SI. We concluded that in western Oregon spring application of 90 kg N ha(-1) for Chewing's fescue and tall fescue and 120 kg N ha(-1) for orchardgrass should be adequate for seed production. For all species, spring N should be applied in one.

AB:   Seed size has been associated with early seedling vigor (i.e., germination rate, emergence rate, and growth) in grasses. This study was conducted to compare seedling development over a 60-d period in the field as affected by heavy seed (HS) (0.19 to 0.21 g 100 seed(-1)) and light seed (LS) (0.13 to 0.16 g 100 seed(-1)) of 'Blackwell' and 'Trailblazer' switchgrass (Panicum virgatum L.). The experiment was conducted in 1995 and 1996 at Lincoln, NE, on a Kennebec silt loam (fine-silty, mixed, superactive, mesic Cumulic Hapludolls). The experimental design was a randomized complete block with four replicates. Seed was separated into two sizes using a South Dakota seed blower. Seed was planted into rows at a rate of 100 pure live seed per meter of row. Plants were excavated and evaluated for shoot weight, leaf area, and root weight. Shoot and root systems were morphologically staged four times during the summer. Seed size differences in switchgrass appeared to produce only slight differences in morphological development of shoot and root systems, leaf area, shoot weight, and adventitious root weight from seedling emergence to 6 wk of growth. Adventitious roots formed more quickly on seedlings from heavier than lighter seed, but the advantage to seedling establishment was minimal even when soil moisture appeared to be lacking. By 8 to 10 wk after emergence, growth and development of LS seedlings were similar to HS seedlings. Once seedlings formed two or more adventitious roots, seed size no longer affected establishment and growth. Seed size in switchgrass appears to have a minimal long-term effect on growth and development of seedlings.

AB:   A critical evaluation of legumes should consider both the above-and belowground contribution to N(2) fixation. Based on the amount of N in crops and correcting for the changes of soil N as a result of cropping, 15 equations are presented for estimation of the apparent net amount of atmospheric N(2) fixed by legumes grown in short- and long-term cropping systems. In the final equation, all components of a legume-cereal rotation system were considered. In estimating N(2) fixation, including in the equation the non-N(2)-fixing crop that follows the legume in the rotation is an innovation of the method, in addition to the system approach concept. The validity and accuracy of each equation in estimating N(2) fixation by legumes is discussed. An example is provided using data from long-term vetch-barley (Vicia sativa L.-Hordeum vulgare L.) rotation studies in Cyprus. The estimated amount of apparent net N(2) fixation by vetch was 184 kg N ha(-1), a quantity twice that usually estimated using only the aboveground vetch production. This result shows the importance of calculating apparent net N(2) fixation by considering above- and belowground system components.

AB:   Oat (Avena sativa L.) intercropped with berseem clover (Trifolium alexandrinum L.), an annual forage legume, has economic and biological advantages for use as a rotation crop in the north-central USA. To investigate the effects of different oat and berseem clover cultivars on the productivity of the intercrop and its components, and to test for interspecific cultivar interactions, we evaluated binary combinations and monocultures of a sample of oat and berseem clover cultivars in three Iowa environments. Oat cultivars varied for oat traits, effects on clover stands and yield, and total intercrop biomass. Berseem clover cultivars varied for forage yield, stand, maturity, damage due to disease and insects, and effects on intercrop biomass. In one environment, only one of seven berseem clover cultivars survived after the first forage harvest. Adding oat to berseem clover reduced total forage and weed yields, clover stands, and relative maturity of clover, but increased total crop biomass and forage plant health. Adding berseem clover to oat did not reduce oat grain or straw yields, and in one year increased oat test weight. Cultivar rankings of each species differed in monoculture vs. intercrop. Interspecific cultivar interactions were not significant for most traits. Greater genetic improvement in the productivity of the oat-berseem clover intercrop will more likely be achieved by improvement of general agronomic productivity of berseem clover than by trying to enhance specific ecological combining ability of particular oat and berseem clover cultivar combinations.

AB:   In Mediterranean environments, translocation of pre-anthesis assimilates to the grain is an important source of photosynthates. In this work, the effect of forage removal at the beginning of jointing on the amount of dry matter (DM) accumulated before anthesis and remobilized during grain filling was studied in five spring and five winter triticale genotypes (x Triticosecale Wittmack). Field experiments were conducted in 1992 and 1993 in northeastern Spain. Two harvesting treatments were used: (i) grain production only and (ii) cutting the crop for forage at the beginning of jointing and harvesting the grain produced after regrowth. Pre-anthesis storage of carbohydrates was very important to grain filling in triticale, both for grain and for dual-purpose. Contribution of pre-anthesis assimilates to grain yield in the uncut plots was 46% in spring triticale genotypes and 65% in winter genotypes, as the later-maturity winter triticale genotypes were more affected by terminal abiotic stresses. Reductions in DM accumulated at anthesis after forage removal were more pronounced in winter genotypes (39%) than in spring genotypes (20%), where an earlier development allowed for a longer recovery period after cutting; DM reductions were similar to grain yield decreases. The effect of forage removal on translocation depended on the growth habit of the genotype and environmental conditions. Most differences were associated with changes in crop phenology. In spring types, with early jointing, DM translocation and the contribution of pre-anthesis assimilates to grain were not affected by forage removal, whereas both traits were drastically reduced in winter triticale. Most differences in (13)C/(12)C carbon.
       isotope discrimination (delta) in grains were also phenology driven.

AB:   Little is known about the pattern of growth and biomass partitioning of spring and winter triticale (X Triticosecale Wittmack), although such information can aid in interpreting the results of field experiments and is an essential step in the development of crop simulation models. This study was conducted to analyze and compare the growth of five winter and five spring triticale genotypes over two years in northeast Spain. Plants were sampled at the main stages of the Zadoks scale, and biomass, LAI and their components, and stem elongation were determined. The relationships between all the growth traits studied and accumulated growing degree-days from sowing (GDD) were described by the same asymmetric logistic peak curve. Genotypic variability could be mainly associated with plant phenology. On average, winter triticale types needed 165 more GDD than spring types to reach maximum LAI. Also, winter triticale genotypes needed 109 more GDD to complete their main stem elongation, and 109 more GDD to reach their maximum rate of dry weight accumulation in the stems than spring genotypes did. The length of the first tiller was closer to the length of the main stem in winter types than in spring types. Both types of triticale had similar patterns of biomass accumulation. The asymmetric logistic peak curve used in this work fitted asymptotic and peak-type relationships, and can be a useful tool for growth studies.

AB:   Because of their deep roots and high water demand, alfalfa (Medicago sativa L.) hay crops can reduce water available to crops following in the rotation. Recharging the soil water profile after alfalfa is, therefore, a high priority in dryland cropping systems. The objective of this study was to investigate effects of alfalfa crop termination date (late June, early August, and in spring immediately before spring wheat seeding) and method (herbicides, tillage, and herbicides plus tillage) on soil water conservation, and establishment, yield, and water use efficiency (WUE) of a following spring wheat (Triticum aestivum L.) crop. Experiments were conducted over 5 site-years in a subhumid region of western Canada. Herbicide termination resulted in greater total water recharge and a faster rate of water recharge than treatments involving tillage. Greater efficiency of soil water recharge for herbicide termination after the first hay harvest (late June) appeared to cause deep water percolation at one site. Delaying termination until after the second hay harvest (early August) did not reduce soil water availability at spring seeding of the following wheat crop, but increased reliance on overwinter soil water recharge. Delaying herbicide treatment until spring reduced water at seeding and wheat yields in some cases. Compared with treatments involving tillage, herbicide treatments resulted in higher levels of groundcover (i.e., greater soil erosion control), higher WUE, and higher grain yields. Herbicide termination after the second hay harvest produced the most favorable overall outcome; better than the traditional approach of tillage after the first hay harvest.

AB:   Hydroponic and greenhouse studies have shown that grain yields of wheat (Triticum aestivum L.) are maximized when the N supply contains a mixture of NH(4) and NO(3). Tillers per plant is the yield component most commonly increased by mixed N nutrition in greenhouse studies. The objective of this study was to evaluate, under field conditions, the response of 'Butte 86' spring wheat to N sources differing greatly in nitrification rate. Nitrogen was applied at 0 or 112 kg N ha(-1); the N sources were calcium nitrate (CN), urea, urea-dicyandiamide (DCD), 0.1-g urea granules, and 0.1-g urea-DCD granules. Six field trials were performed. Topsoil (0-15 cm) analysis of fertilized plots during tillering indicated a wide range of mineral N contents (19-101 mg N kg(-1) and of NH(4):NO(3) mole ratios (0.04-2.06). Correlation analyses suggested that tillering was sensitive to the total mineral N supply, but quite insensitive to the NH(4); NO(3) ratio in the topsoil. Vegetative growth and N uptake were generally lower for CN than for the other N sources. At some locations, more heads per square meter at harvest were observed with the slower-nitrifying N sources. Grain yields were increased by N fertilization, but significant differences between N sources were not generally observed. For both years of the study, the 0.1-g urea-DCD granules gave the highest N uptake efficiency. However, the dramatic responses in growth, tillering, or grain yield routinely observed with mixed N nutrition in hydroponic or greenhouse studies could not be duplicated in the field.

AB:   Intensive land use in the Rolling Pampa of Argentina appears to be reducing soil quality for crop production. Our objective was to establish the best edaphic and/or plant indicators for assessing soil quality with regard to functioning as a medium for crop production. Nine fields with Typic Argiudoll soils were selected for evaluation based on agriculture history and apparent soil structural stability. Soil chemical and physical properties and maize (Zea mays L.) vegetative and reproductive characteristics were measured. Multivariate statistical analyses were applied to the data to determine potential indicators of soil quality. Soil and crop variables explained more than 70% of the variance in soil quality among agricultural histories. The edaphic indicators that showed the greatest change from pristine conditions were organic C, total N, P, Mg, K, B, Ca, and Zn contents and cation exchange capacity. Using crop variables, leaf length, maximum fraction of intercepted photosynthetically active radiation, grain yield, kernel number, prolificacy, and total dry matter at physiological maturity, served to establish a soil quality gradient. Variation of maize growth was associated with edaphic indicators of soil quality and revealed the importance of soil aggregate stability in determine changes in soil quality for crop production.

AB:   Crop productivity under dryland conditions is largely limited by soil water availability. Soil organic matter (SOM) contents have been found to be a reliable index of crop productivity in semiarid regions because it positively affects soil water-holding capacity. Our objectives were to explain differences in wheat (Triticum aestivum L.) yields in response to SOM levels and related properties and to quantify the contribution of a unit increment of SOM content to soil productivity during 1991, 1992, and 1994 on a total of 134 production fields in the semiarid Argentine Pampas. Wheat yields were related to both soil water retention and total organic C (TOC) contents in the top layers 0-20 cm) in years with low moisture availability (1992 [r =  0.51, P < 0.01] and 1994 [r =  0.59, P < 0.01]), and were related to both total N and available P contents in a year without water deficit stress (1991 [r = 0.58, P < 0.01). Wheat yields over all years were linearly related to TOC (r = 0.68, P < 0.01) when these contents were <17.5 g kg(-1). Dependence of wheat yields on soil water retention and on TOC contents under water deficit was related to the positive effect of these soil components on plant-available water. In the absence of water deficit (1991), nutrient availability was the limiting factor. Losses of 1 Mg SOM ha(-1) were associated with a decrease in wheat yield of approximately 40 kg ha(-1). These results demonstrate the importance of using cultural practices that minimize losses of soil organic C in the semiarid Argentine Pampas.

AB:   Daily crop water uptake was simulated using algorithms from three crop simulation models, CropSyst, CERES, and EPIC (listed in order of decreasing process detail). Simulated results were compared with measurements of sap flow and soil water content for maize (Zea mays L.) growing at Prosser, WA, under a wet and a dry irrigation treatment, and with soil water content measurements for nonirrigated maize at Davis, CA. At Prosser, the dry treatment imposed only a mild stress; at Davis, the stress was severe. Simulation variables such as maximum crop evapotranspiration, root density by soil layer, and green leaf area index were provided as daily input. At Prosser, all algorithms performed similarly when simulating crop water uptake. For the wet treatment, the root mean square error (RMSE) was 0.27 to 0.28 mm d(-1) , and the relative error [RE = 100 (RMSE/Measured average) was 7.0 to 7.2%. For the dry treatment, simulation accuracy decreased (RMSE = 0.33-0.38 mm d(-1); RE = 9.0-10.5%). The time evolution of water uptake simulated by CropSyst better depicted the measured sap flow (water uptake) difference between wet and dry treatments. Simulations of soil water content by layer for the wet treatment, compared with measurements available for 17 d, yielded RMSEs from 0.022 to 0.024 m(3) m(-3) and REs from 8.5 to 9.2%. For the dry treatment (12 d of measurements), the best simulations were obtained with the water uptake algorithms from CropSyst and CERES, with RMSE = 0.015 m(3) m(3) (both models) and RE = 6.4% (CropSyst) and 6.6% (CERES), compared with RMSE=0.019 m(3) m(-3) and RE = 8.1% for EPIC. Under the severe water stress at Davis, CropSyst had the best performance.
       This algorithm simulated changes in soil water content by layer (8 d of measurements available) with RMSE of 0.011 m3 m-3 and RE of 5.0%, while the RMSE and RE values for CERES and EPIC were 0.016 and 0.019 m(3) m(-3) and 7.6 and 9.0%, respectively. The more process-oriented algorithm (CropSyst) showed an increasing advantage as water stress severity increased. The EPIC algorithm had the poorest performance under water stress. This could be improved by modifying the value of the water extraction distribution parameter in EPIC, but with this change the wet treatment simulations at Prosser deteriorated substantially, indicative of limitations in EPIC's simple approach.

AB:   Dynamic crop-growth models are used to project the effects of rising atmospheric CO(2) concentration and associated climate change on crop yields. Such model predictions are largely untested in the field, for lack of experimental data. We tested the CERES -Wheat model, modified to include leaf-level photosynthesis response to elevated CO(2), using field data from 2 yr of Free-Air Carbon Dioxide Enrichment (FACE) experiments with spring wheat (Triticum aestivum L. cv. Yecora Rojo) in Maricopa, AZ. Two irrigation treatments (well-watered, WW; water-deficit stressed, WS) and two atmospheric CO(2) concentrations (ambient, 350 micromole mol(-1); elevated, 550 micromole mol(-1) were simulated. The model was evaluated using measurements of crop phenology, aboveground dry matter (DM) production, grain yield, and evapotranspiration (ET). Model calculations of crop phenology were within 2 to 3 d of observed values under WW, ambient CO(2) conditions in both years. The model did not simulate the accelerated crop phenology (5-8 d at physiological maturity) observed in the WW and elevated CO(2) treatments, indicating the need to include effects of increased stomatal resistance on canopy temperature. Simulations of DM and grain yield were within 10% of measured values, except for a tendency to overcalculate DM response to CO(2) by 10 to 15% in Year 1 for WS treatments. The model undercalculated cumulative ET under WW conditions by 15%; model sensitivity analyses suggest that simulation of potential evapotranspiration (PET) was too low for this arid site. The model reproduced measured dynamics of CO2-water interactions. Simulated reductions in water loss due to elevated CO2.
       were about 4%, in agreement with measurements. The model simulated larger increases in DM production and yield due to elevated CO2 under WS than under WW conditions. In Year 1, simulated crop response to CO2 was 2% larger (measured: 3%) under WS than under WW conditions; in Year 2, it was 11% larger (measured: 9%). The ability to simulate CO2-water interactions, though it needs to be further evaluated with additional experimental datasets, is an important attribute of models used to project crop yields under elevated CO2 and climate change.

AB:   The Ohio Management Systems Evaluation Areas (MSEA) project focused on developing and evaluating improved agricultural management systems and predictive models. The Root Zone Water Quality Model (RZWQM) is an environmental model for simulating water, chemical, and biological response of agricultural management systems. This paper presents calibration and evaluation of the generic plant productions model of RZWQM, as well as some evaluation results for the nitrate and soil water content predictions. Corn (Zea mays L.) and soy bean (Glycine max (L.) Merr.] biomass data collected at the Ohio MSEA from 1991 to 1993 were used for evaluation. Data from 1992 were used in calibrating RZWQM, and data from two other years (1991 and 1993) at the same site were used for validation. Crop growth predictions were compared with observed values of leaf, stem, and seed biomass collected throughout the growing season. Leaf and stem biomass predictions generally fell within 1 SD of the observed values, but for all years there were dates when predictions were outside of the observed range. RZWQM predicted seed biomass or yield adequately for all 3 years with predictions falling within 1 SD of the observed values. Soil water content estimates for corn were higher than observed values late in the season, perhaps because of underestimates if evapotranspiration due to errors in leaf area predictions. The model overpredicted nitrate concentrations for the corn plot late in the season. Nitrate concentrations for the soybean plot were generally underpredicted. These differences may be due to underestimates of the fast humus pool of the nutrient model and of the N(2) fixation rate for.
       soybean. More evaluation is needed to refine the nitrate and soil water content predictions.

AB:   Evaluation of agricultural simulation models against field observations is needed to gauge their usefulness. This study was conducted to assess the ability of the Root Zone Water Quality Model (RZWQM) to simulate dryland and irrigated corn (Zea mays L.) production systems in semiarid eastern Colorado. The model was first parameterized for corn using field data from a single season. Different parameters were identified for irrigated and dry land corn. The parameterized model was run on independent data sets from the following year (irrigated) and different soils and sites (dryland) and model results were compared with field measurements. Differences between modeled and measured components of soil water content, evapotranspiration, grain yield and biomass, and crop N uptake ranged from 1 to 23% in the dryland study and from 1 to 28% in the irrigated study. On a seasonal basis, model estimates of seepage below the root zone were within 3% of measured values, while NO(3)-N leaching was overpredicted by 79%. Note that model parameterization relied solely on single-season data. This could potentially produce bias in parameter values due to the narrowness of the prevailing conditions during that single season. For this reason and for the purpose of using the model to assess the long-term impact of alternative practices, further work on parameterization and evaluation of the model needs to focus on using experimental observations from multiple seasons.

AB:   The Root Zone Water Quality Model (RZWQM) was evaluated for a region that has a long history of irrigated corn (Zea mays L.). Imprecise irrigation and plentiful fertilizer applications have contributed to the buildup of NO(3)-N in ground water, where concentrations often exceed 30 mg L(-1). Experiments were conducted to evaluate the effects of management practices on corn yield, N uptake, plant biomass, leaf area development, soil water content, and soil N. Field-measured results from 1992 were used to calibrate RZWQM. The model was evaluated by simulating three irrigation levels and five fertilizer rates for 1993 and 1994. The model simulated the soil water pattern satisfactorily during most of the growing season; however, the simulated soil profile water content was lower than field conditions in the spring and fall. Transpiration appears to be excessive when the leaf area index (LAI) is small. Simulated yields exceeded measured values, with the largest errors for small fertilizer applications in 1993 and for large fertilizer applications in 1994. The mean error between measured and modeled yields was 2.9 Mg ha(-1), with a root mean square error (RMSE) equal to 46% of the mean yield for all treatments over the 3 years. Estimates of LAI and aboveground biomass were closer to measured values, with mean errors of 5% for leaf area and 1% for biomass. The relative RMSE for LAI and biomass was 26 and 17% respectively. The model underestimated aboveground N uptake, with a mean error of 25 kg N ha(-1) and a relative RMSE of 41% while development of the comprehensive RZWQM has been constructive, improvements are still needed. Excessive depletions in the spring and fall.
       overstate storage of off-season precipitation, and this leads to underestimating annual leaching losses. Combining excessive yield predictions with low N uptake estimates exaggerates the N use efficiency. These discrepancies will have a profound effect on the simulated impact of management practices. Leaching losses and yield effects will be understated, which may lead to development of policies that affect producers more severely than the model implies.

AB:   Before simulation models can be used to evaluate the benefits of alternative management systems, their accuracy needs to be examined. This study evaluated the performance of the Root Zone Water Quality Model (RZWQM Version 3.2) against crop yield and water, nitrate and herbicide fate and transport during four years of a corn-soybean [Zea mays L.-Glycine max (L.) Merr.] rotation. The model was calibrated and initialized using default values supplied with the model and adjusting model parameters to obtain stable organic matter and microorganism pools. The model was further calibrated to match crop yields for the first two years of measurements. For the second two years, predicted soybean yield was within 60 kg ha(-1) (3%) of measured yield but predicted corn yield was underpredicted by 790 kg ha(-1) (10%). Disagreements between modeled and measured yields may be due to factors not included in the model such as disease and insect damage. The model estimated total soil nitrate content well, although nitritication rates during winter were overestimated. Predicted nitrate leaching out of the root zone agreed well with measured losses to tile drainage. Predictions of herbicide residues with the one-parameter lumped dissipation model option were best after reducing the expected half-lives of metribuzin [4-amino-6-(1,1-dimethylethyl)-3- (methylthio)-1,2, 4-triazin-5(4H)-one], or atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3, 5-triazine-2,4-diamine], by a factor of four. The two-parameter lumped half-life model option improved the prediction for atrazine but not for metribuzin. Predictions of herbicide losses in drainage water were overestimated in the second year following herbicide.
       application. Neither nitrate nor herbicide concentrations in the soil profile were modeled satisfactorily. Invoking the macropore option of the model did not consistently improve model prediction of a herbicide leaching. Overall, the model shows promise in predicting the interplay of climate, soil, and management on crop yield and nitrate fate, but evaluation over a wide range of conditions is needed.

AB:   The USDA-ARS Root Zone Water Quality Model (RZWQM) is a comprehensive computer model developed to simulate water, chemical, and biological processes in the root zone of agricultural management systems. The model is capable of evaluating the effects of various cropping and management practices on surface and ground water quality. In this study, the performance of RZWQM Version 3.2 was evaluated for a claypan soil, particularly surface runoff and chemical loss to surface runoff predictions. The model was calibrated and evaluated using data collected from the Missouri Management Systems Evaluation Area (MSEA) and the Kingdom City runoff plots. Soil water predictions of the model compared well with those measured, particularly at the 15-, 60-, 75-, and 90-cm soil depths. In most cases corn (Zea mays L.) and soybean Glycine max (L.) Merr.] yield predictions were within 15% and 20%, respectively, of those measured. Using the macropore option (constant cracking) greatly improved the prediction of chemical losses to seepage. Annual runoff simulated for corn and soybean under conventional and no-till systems was adequately predicted. The model underpredicted large runoff events and overpredicted runoff events  that occurred after long dry periods when soil cracking was a dominant factor. The model overpredicted NO-(-3)-N concentrations in runoff but underpredicted concentrations in near-surface soils. Predicted and measured atrazine [6-chloro-N-ethyl-N'-(1-methylethyl)-1,3,5-triazine-2, 4-diamine] and alachlor [2-chloro-N-(2,6-diethylphenyl)-N-(methoxymethyl) acetamide) concentrations in surface runoff compared well, particularly when the computed runoff was closed to that measured. In this study, the model.
       was run using the option of constant cracking in the soil. To improve the predictions of agrichemical losses to runoff and seepage, RZWQM should include the capability to predict variable soil cracking based on soil moisture.

AB:   Testing of simulation models against field-measured data is an important step that must be taken before a model can be used as a management tool. Field soil water contents, intensively measured by time-domain reflectometry (TDR) on a Zimmerman fine sand soil (Argic Udipsamments) in the Minnesota Management Systems Evaluation Area (MSEA), were used to evaluate the Root Zone Water Quality Model (RZWQM) over two rotated crop growing seasons in 1992 (corn, Zea mays L.) and 1993 [soybean, Glycine max (L.) Merr.]. The model was evaluated based on laboratory-measured soil hydraulic properties. Reasonable agreement exists between the daily TDR measured and RZWQM-predicted water contents for the upper soil depths. However, the model overestimated the lower soil profile, leading to a consistent overestimation of the total water depth (TWD) in the entire root zone (0 to 150 cm) during both the 1992 and 1993 growing seasons. The maximum errors in TWD for the entire root zone were 2.47 and 2.77 cm,  respectively in 1992 and 1993. Predictions of solute transport by RZWQM were examined for three herbicides: atrazine [6-chloro-N-ethy-N'- (1-methylethyl)-1,3,5-triazine-2,4- diamine], alachlor [2-chloro-N-(2,6- diethylphenyl)-N- (methoxymethyl)acetamide], and metribuzin  [4-amino-6-(1,1-dimethylethyl)-3- (methylthio)-1,2,4-triazin-5(4H)-one]. Comparison between measured and predicted soil herbicide concentrations averaged over the top 15-cm layer showed that the model matched the temporal changes of the field measurements reasonably well, although the measurements showed that all pesticides were somewhat more persistent over time than the model predicted.

AB:   Potato fields and cut (ungrazed) grassland in SE Scotland gave greater annual N2O emissions per ha (1.0-3.2 kg N2O-N ha-1) than spring barley or winter wheat fields (0.3-0.8 kg N2O-N ha-1), but in terms of emission per unit of N applied the order was potatoes > barley > grass > wheat. On the arable land, especially the potato fields, a large part of the emissions occurred after harvest. When the grassland data were combined with those for 2 years' earlier work at the same site, the mean emission over 3 years, for fertilization with ammonium nitrate, was 2.24 kg N2O-N ha-1 (0.62% of the N applied). Also, a very strong relationship between N2O emission and soil nitrate content was found for the grassland, provided the water-filled pore space was > 70%. Significant relationships were also found between the emissions from potato fields and the soil mineral N content, with the added feature that the emission per unit of soil mineral N was an order of magnitude larger after harvest than before, possibly due to the effect of labile organic residues on denitrification. Generally the emissions measured were lower, as a function of the N applied, than those used as the basis for the current value adopted by IPCC, possibly because spring/early summer temperatures in SE Scotland are lower than those where the other data were obtained. The role of other factors contributing to emissions, e.g. winter freeze-thaw events and green manure inputs, are discussed, together with the possible implications of future increases in nitrogen fertilizer use in the tropics.

AB:   Hereford X Angus steers were used in a 13-treatment, four-period, incomplete Latin square design to examine the effects of starch and degradable intake protein (DIP) supplements on forage utilization and ruminal function. Steers were given ad libitum access to low-quality hay (4.9% CP) and were not supplemented (NS) or received different amounts of starch (cornstarch grits; 0, .15, and .3% of initial BW) and DIP (Na-caseinate; .03, .06, .09, and .12% of initial BW) administered via ruminal fistulae in a 3 X 4 factorial arrangement of treatments. Supplemented steers consumed more (P < .01) forage OM, total OM, NDF, and digestible OM (DOM) than NS steers. Forage OM, total OM, NDF, and DOM intakes increased linearly (P < .01) as the amount of supplemental DIP increased. The addition of starch to supplements linearly decreased (P < .01) the intake of forage OM, NDF, and DOM. The digestion of DM, OM, and NDF increased linearly (P < .01) with supplemental DIP and decreased linearly (P less than or equal to .06) with supplemental starch. Particulate and liquid passages generally increased with DIP; however, starch level influenced the nature of the response (P = .03 and .06, respectively). Similarly, ruminal acid detergent-insoluble ash content generally decreased as starch increased, but the effect was dependent on DIP level (P < .01). Supplementation increased (P < .01) ruminal NH3 and total VFA and decreased (P < .01) ruminal pH relative to NS. All treatments supported average pH values in a range (6.3 to 6.7) unlikely to inhibit fibrolytic bacteria. Ruminal NH3 concentration increased quadratically (P = .03) with DIP and decreased linearly (P = .02) with starch. As.

AB:   Six Angus steers (260 +/- 4 kg initial BW) fitted with ruminal, duodenal, and ileal cannulas were used in a 6 X 6 Latin square design to evaluate the effect of feeding poultry by-product meal (PBM) on small intestinal flow and disappearance of amino acids. The diets were provided at 2% of BW on a DM basis, formulated to contain 11.5% CP, and consisted of 49% corn silage, 36% cottonseed hulls, and 15% supplement on a DM basis. Supplements were formulated to contain 37% CP with sources of supplemental N being soybean meal (100% SBM) and 0, 25, 50, 75, and 100% PBM, with urea used to balance for N. Duodenal flow of all amino acids increased linearly (P < .07) as PBM increased in the diet and, except for His, increased (P < .09) for 100% PBM compared with 100% SBM. Similar results were observed for duodenal flow of nonbacterial amino acids, which linearly increased (P < .05) with PBM and were greater (P < .05) for 100% PBM than for 100% SBM. Soybean meal increased (P < .09) the duodenal flow of nonbacterial Lys compared with 0% PBM, and 0% PBM increased (P < .04) flow of Val, Ala, and Pro compared with 100% SBM. Duodenal bacterial essential, nonessential, and total amino acid flows were not affected (P > .80) by PBM, however, they were greater (P < .02) for 100% SBM than for 100% PBM. In addition, nonessential and total bacterial amino acid flows were increased (P < .06) for 100% SBM compared with 0% PBM. Small intestinal disappearance of Lys and Pro increased linearly (P < .09) as PBM increased, and 100% PBM increased (P < .07) disappearance of Arg and Ala compared with 100% SBM. Supplemental N source had no effect (P > .31) on apparent small intestinal disappearance of essential, nonessential.
       and total amino acids. These data suggest that when PBM, SBM, and urea were used as sources of supplemental N, the daily disappearance of amino acids from the small intestine of steer calves consuming a corn silage- and cottonseed hull-based diet was similar.

AB:   Multiparous (n = 26) and primiparous (n = 18) Holstein cows were fed prepartum and postpartum total mixed diets that were, or were not, supplemented with a yeast culture (YC) for approximately 23 d prepartum and 56 d postpartum. Multiparous cows supplemented with YC selected a prepartum diet higher in CP than did unsupplemented cows, although prepartum performance of cows of both parities, as assessed by DMI and measures of body status, was not influenced by YC. The extent of the prepartum DMI depression was not influenced by YC supplementation in cows of either parity. An intake behavior study with six multiparous cows suggested that cows supplemented with YC exhibited repeated diurnal feed intake patterns until approximately 7 d prepartum, vs 10 d prepartum for unsupplemented cows. Cows of both parities supplemented with YC had numerically higher DMI and production of milk and milk components, although only DMI for multiparous cows and milk production for primiparous cows approached statistical significance. Intake behavior results suggested that cows supplemented with YC achieved repeated diurnal feed intake patterns by approximately 14 d postpartum, vs 20 d postpartum for unsupplemented cows. Concentrations of ruminal metabolites and pH did not differ between treatments, although ruminal fluid collection occurred while diurnal feed intake patterns were repeated (regular). Overall, our results can be interpreted to support a trend toward a modest postpartum improvement in performance of primiparous and multiparous cows supplemented with this YC for 23 d prepartum and 56 d postpartum. However, primiparous cows seemed to achieve this modest overall improvement primarily through enhanced.
       postpartum DMI, whereas in multiparous cows it was due almost equally to enhanced postpartum DMI and higher energy density of the diet.

AB:   Four ruminally cannulated cows were used to assess the distribution of the concentrations and carbohydrate-degrading enzyme activities of the liquid-associated protozoa (LAP) and solid-associated bacteria (SAB) in the rumen. The cows were fed diets (7 kg of DM/d) of 100% hay (Diet F) or 60% barley plus 40% hay (Diet C) in a 2 X 2 crossover experimental design. Samples of ruminal digesta were collected successively from the dorsal (DS), ventral (VS), and anterior (AS) sacs 1 h before and 3 h after the morning feeding on two sampling days with a 2-d interval. Irrespective of diet and sampling time, the greatest proportion of entodiniomorphs, representing the main population of protozoa, was found in the DS (40% mean; P < .05). Low pH values observed in the DS (P < .05) indicated higher fermentative activity in this site than in the other parts of the rumen. Protozoa may contribute more than previously thought to the high digestive potential present at the top of the rumen that has classically been attributed to bacteria. The specific activity of plant cell wall polysaccharide-degrading enzymes in the LAP was correspondingly greater (P < .05) for DS than for VS or AS. For the two diets and sampling times, specific activity of fibrolytic enzymes in the SAB tended to be less in the upper than in the lower parts of the rumen, and less in the VS than in the AS. This tendency became significant (P < .05) for total fibrolytic enzyme activity. Differences in bacterial colonization of particles among the three sampling sites may explain such differences in fibrolytic activity of the SAB. Data suggest a spatio-temporal complementary action of the bacteria and protozoa in ruminal plant cell wall degradation.

AB:   Efficiency of limit-feeding a whole shelled corn-based diet as an alternate to a conventional forage-based diet for nonlactating dairy cattle was determined. Twelve nonlactating, multiparous Holstein cows (initial BW 642 +/- 50 kg) were used in a randomized complete block design. Nutrient digestibility, excretion of DM, N, and P, performance of cows, and feed costs were measured. Both diets were formulated to provide equal daily intakes of NE1, protein, vitamins, and minerals, according to National Research Council recommendations. Dry matter intake was restricted by 30% for cows fed the high-corn diet compared with the high-forage diet (6.8 vs 9.6 kg/d, respectively); therefore, concentrations of nutrients in the high-corn diet were increased to compensate for decreased DMI. Diets were fed once daily, and cows had unlimited access to fresh water. After a 28-d adaptation period, cows were placed in metabolism stalls for a 6-d total collection of feces and urine. The limit-fed, high-corn diet had a 15% greater DM digestibility than the high-forage diet. A 29% decrease in DMI for the high-corn diet vs the high-forage diet resulted in a 40% decrease in fecal DM excretion. Starch digestibility and digestibility of whole corn kernels were not affected (P greater than or equal to .62) by diet. Despite similar N intakes, total N excretion was 22% greater (P < .01) for cows fed the high-forage diet than for those limit-fed the high-grain diet. Cow weight and condition score change did not differ (P > .10) between diets. Feed costs were reduced by $.38/d with the high-corn diet vs the high-forage diet. Limit-feeding a corn-based diet is an economically and nutritionally viable alternative to forage-based.

AB:   Five ruminally fistulated 3-yr-old mature Holstein steers (average BW 691 +/- 23 kg) were used in a 5 X 5 Latin square experiment with a 2 X 2 + 1 factorial arrangement of treatments. Effects of protein concentration and protein source on nutrient digestibility, excretion of DM and fecal N, ruminal fluid volume and dilution rate, ruminal characteristics, and in situ DM disappearance of whole shelled corn, ground corn, and orchardgrass hay were measured in steers limit-fed high-concentrate diets at 1.5% of BW. A negative control basal diet (NC; 9% CP) was supplemented to achieve either 11 or 14% CP; supplemental CP was either from soybean meal (11 and 14% SBM) or a 50:50 ratio of CP from urea and soybean meal (11 and 14% U). Dry matter and OM digestibilities were 5% greater (P < .07) for steers fed the SBM diets than for those fed the U diets. Starch digestibility did not differ (P > .10) among steers fed any of the diets. Nitrogen source did not affect (P > .10) apparent N digestibility or fecal N excretion; however, steers fed the NC diet had the lowest (P < .10) apparent N digestibility compared with those fed all other diets. Ruminal fluid volume was lower (P < .06) when steers were fed the NC diet compared with all other diets; there were no differences (P > .74) among diets for rununal fluid dilution rate. In general, ruminal ammonia N and VFA molar proportions were not affected by protein source or concentration. Although CP concentration affected (P < .06) in situ DM disappearance of ground corn, CP concentration did not ( P > .48) affect total tract digestion of DM or OM. This indicates that CP concentration may have affected site of digestion, but not extent of digestion. When mature ruminants.
       were limit-fed a corn-based diet to meet primarily a maintenance function, protein source and concentration had little effect on measures of nutrient digestion.

AB:   The inheritance of net photosynthesis and transpiration efficiency in spring wheat under drought were studied in two years in order to determine their heritability. The parents, F(1) and segregating generations (F(2), BC(1), BC(2)) of four crosses between each of two drought-resistant and two drought-susceptible genotypes were evaluated under drought in pots under glasshouse conditions. Measurements of gas exchange were made using a portable gas-analysis system. Generation means and variance component analyses of the data suggested that these traits are simply inherited and controlled mainly by additive genetic variation. Narrow-sense heritability estimates varies between crosses from 61% to 84% for net photosynthesis and from 88% for transpiration efficiency.

AB:   A number of resistance sources for the Russian wheat aphid have been reported in the last few years and were used to develop cultivars from current commercial cultivars in various breeding programmes. It can be difficult to distinguish between the cultivars with and without resistant without actual infestation and so in this study we looked at low molecular weight glutenin subunits (LMW-GS) of the two groups. Distinctly different banding patterns were found for the cultivars tested and their isogenic counterparts. Although the LMW-GS and DN1 and DN5 are coded on different chromosomes, the LMW-GS are highly repeatable and banding profiles of each cultivar can be used for the identification of unknown seed.

AB:   The influence of fiber source on fiber digestion and mean retention time was investigated. Six fibrous feedstuffs with wide differences in chemical composition and particle size were selected: paprika meal, olive leaves, alfalfa hay, soybean hulls, sodium hydroxide-treated barley straw, and sunflower hulls. Six diets were formulated to contain one of these ingredients as the sole source of fiber. To avoid nutrient imbalances, fiber sources were supplemented with different proportions of a concentrate free of fiber based on soy protein isolate, wheat flour, lard, and a vitamin and mineral mix to obtain diets containing at least 18.5% CP and 5% starch. Fecal apparent digestibility of nonstarch polyeaccharides (NSPd) and its monomers, NDF, NDF-ADL, and ADF-ADL, were determined using four New Zealand White X California growing rabbits per diet. Total, ileorectal, and cecal mean retention times (tMRT, i-rMRT, and cMRT, respectively) were determined for diets based on paprika meal, olive leaves, soybean hulls, and sunflower hulls in 16 does (four per diet) fitted with T-cannulas at the terminal ileum. In both trials, DMI was negatively correlated with the proportion of fine particles (FP: < .315 mm) and positively correlated with the proportion of large particles (LP: > 1.25 mm) (P < .01). Stepwise regression analysis showed that FP was the dietary characteristic best related to digestibilities of NSP, uronic acids, glucose and NDF, tMRT, and cMRT (P < .001), showing a positive correlation with these variables. In all these cases, this procedure selected the proportion of large particles as a second variable in the model. Degree of lignification of NDF, considering lignin.
       as the difference between ADL and acid detergent cutin, was only included as the third variable for the model of NDF digestibility. Digestibility of NSP was positively correlated with those of NDF, NDF-ADL, and ADF-ADL (r = .82, .87 and .85, respectively, P < .001); the latter was also highly correlated with the digestibility of the glucose included in the NSP fraction (r = .86; P < .001). Cecal mean retention time accounted for 63% of average tMRT, for most of the variability in tMRT (r = .99; P < .001), and was positively related to NSPd (r = .89; P < .001). From these results, we conclude that particle size is a major factor affecting fiber digestion efficiency, rate of passage, and feed intake in rabbits.

AB:   The assessment of polymorphism exhibited by molecular markers is an arduous but essential task that facilitates the use of molecular tools by breeders and geneticists. For that purpose, the value of a wheat composite population was assessed for characterizing the diversity of restriction fragment length polymorphism (RFLP) markers developed by INRA-Genoble. The polymorphism of 13 genomic probes was measured over a set of 80 inbred lines randomly extracted by single-seed descent from a composite-cross of 16 wheat lines. The 13 probe-enzyme combinations revealed 27 loci with codominant polymorphism. As many bands were so far unmapped, the segregational analysis of the progenies appeared very suitable for complex patterns, both in determining allelic relationships and in revealing linkage between loci. Allelic diversity, band sizes and chromosomal location assessed from nullisomic-tetrasomic lines are given for the 27 loci.

AB:   Chromosome 3A wheat is known to carry earliness per se genes. To determine the number of genes and their arm location, ear emergence time under a controlled environment was investigated using ditelosomic lines and homozygous recombinant substitution lines developed between chromosome 3A homologues from 'Timstein' and 'Chinese Spring' (CS) in a CS genetic background. Because the ear emergence distribution was discontinuous and two separate modes were produced, the 86 recombinant lines could be divided into 21 lines as the early 'Tinstein' 3A type and 65 lines as the late CS type. This agrees with the 1:3 independent segregation of two genes both located on chromosome 3A. Therefore, two hypotheses can be proposed, either CS ('Timstein' 3A) carries two genes and both are necessary to give early ear emergence, or one gene for early emergence is present on 'Timstein' 3A, but a suppressor is on CS 3A. The behavior of ditelosomic 3AL and 3AS lines, with an ear emergence time identical to that of CS, suggested that one gene is located on the long arm and the other is on the short arm.

AB:   1. A 70-d experiment was conducted to determine the response of 26-week-old laying pullets to cereal-free diets based on maize offal, cassava peel and full-fat cashew nut meal (CNM) in comparison with a standard 550 g maize/kg reference diet. The 4 test diets all contained 315 g CNM/kg 232(.)5, 155(.)0, 77(.)5 and 0(.)0 g/kg of maize offal in combination with 77(.)5, 155(.)0, 232(.)5 and 315(.)0 g/kg of cassava peel, respectively. 2. Pullets fed on the 4 CNM-based diets consumed (P<0(.)05) less food than those fed on the reference diet; they also had lower (P<0(.)05) rates of lay, produced less (P<0(.)05) egg mass, had lower (P<0(.)05) food conversion efficiencies and their eggs had a lighter (P<0(.)05) yolk colour. Pullets fed some of the CNM-based diets also gained more (P<0(.)05) weight, the heaviest (P<0(.)05)being birds reared on the diet containing 315 g/kg cassava peel. Egg weight, shell thickness and albumen height from all eggs were similar. Pullets fed on the CNM-based diets had inferior (P<0(.)05) retention of dry matter and protein. 4. It was concluded that feeding full-fat CNM allowed for high dietary inclusion rates of cassava peel and maize offal and the resultant diets, which contained no maize, supported satisfactory performance of laying hens.

AB:   1. Two experiments were carried out to investigate the addition of 1(.)3 kg water per kg air-dry mash diets containing high proportions (600 to 700 g/kg) of ground cereal grains (wheat, barley or oats) on broiler performance and the structure and function of the gastro-intestinal tract. 2. Chicks at the age of 7 d were fed on the wheat-, barley- or oats-based diets in the dry or wet forms for 35 d. Food and water intakes were recorded daily while body weight was measured weekly. Two birds from each treatment were killed each week to measure gut size and the viscosity of gut contents. Tissue samples from various digestive segments were histo-morphologically examined to determine the thickness of tissue layers, size of tissue glands, villa heights, crypt depths and thickness of tunica muscularis. Crypt cell proliferation rate (CCPR) for each segment was also determined using a metaphase arrest technique. 3. The results from both experiments showed that wetting food significantly (P<0(.)05) increased food intake, total water intake and body weight gain of broiler chickens. The body weight gain of birds were proportional to their food intakes so that the efficiency of food utilisation was similar for all treatments. Dry matter retention of food tended to increase in birds given wet food from 7 to 21 d but not thereafter, compared to the dry-fed birds. Although water intake from the water bottle was significantly (P<0(.)05) reduced in birds given wet food, total water intakes from the water bottle plus that from food were significantly (P<0(.)05) higher in the wet-fed birds than in the dry-fed birds. The ratio of total water to dry food intake was, however, similar in both feeding regimens.
       4. The fresh empty weight of the gut was increased by wet-feeding while its relative weight to body weight and the length of gut was not affected by dietary treatments. Significantly greater development of the tissue glands in the proventriculus and gizzard was observed in the birds given wet food; this was associated with the reduced thickness of the muscular layer of these segments. An increase in villus height was also observed in duodenum, small intestine, caeca and colon of birds given wet food, compared to those given dry food. CCPR was significantly (P<0(.)05) reduced by wet-feeding throughout the digestive tract. This was associated with a significant decrease in the mean viscosity of the gut contents and the concentration of volatile fatty acids (VFAs) in the caeca. 5. Wetting diets based on cereal grains caused a significant improvement in the performance of broiler chickens. The mechanism of the beneficial effects of wet feeding could be attributed to the decreased viscosity of gut contents; the greater development of the layer of villi in the digestive segments and the reduced CCPR in the crypts of the epithelium.

AB:   Differential screening cDNA libraries of unfertilized egg cells and in vitro zygotes of maize resulted in the isolation of more than 50 different genes whose expression is up- or down-regulated after in vitro fertilization (IVF). Amoung these genes we identified a cDNA encoding the eukaryotic translation initiation factor eIF-5A. This highly conserved factor is thought to be necessary for selective mRNA stabilization and translation. It is also the only known protein that contains the unusual amino acid hypusine which is required for biological activity. High transcript amounts are stored in the egg cell, which is, in terms of metabolism, relatively inactive. Upon fertilization transcript amounts decrease, in contrast to metabolically inactive embryos in which the transcript cannot be detected and transcript levels increase up on germination. The expression pattern during the first embryonic cell cycle is also different from that observed during the somatic cell cycle: egg cells in the G0 phase contain high transcript levels, while arrested suspension cells contain few transcripts. In the somatic cell cycle, eif-5A is strongly induced during the G1 phase and transcripts are continuously degraded during the S, G2 and M phases until new induction during the G1 phase of the next cycle. eif-5A, a member of a small gene family in maize, is expressed in most maize tissues investigated. Based on our results, we suggest that the unfertilized egg cell of maize, although relatively inactive regarding its metabolism, is prepared for selective mRNA translation that is quickly triggered after fertilization. We also suggest that the regulation of eif-5A in the first embryonic cell cycle is.
       different from the somatic cell cycle.

AB:   Under states of protein deficiency, the dietary limiting amino acid, rather than protein content, can act as the dietary stimulus to control diet selection. If fact, threonine-deficient rats will alter their diet selection patterns solely on the basis of very small changes (0.009 g/100 g) in the dietary threonine concentration. In these studies, we assessed whether lysine-deficient rats will also alter their diet selection patterns on the basis of small changes in dietary Lys concentration. In all experiments, growing rats were adapted to diets in which the protein fraction (purified amino acids or wheat gluten) was limiting in Lys. They were then given a choice between the adaptation diet (AD) diet and a slightly more deficient diet. Rats that were adapted to a Lys-deficient diet (0.25 g Lys/100 g) selected their AD over diets containing as little as 0.01% less Lys (P < 0.01) within 5 d. To determine how deficient rats must be before they alter their selection patterns, rats were adapted to diets containing various levels of Lys, i.e., 2 levels below the requirement for growth and 2 levels above the requirement for growth, but below the requirement for maximal nitrogen retention. Only rats adapted to diets containing Lys below their requirement for growth selected their AD over a diet containing 0.05% less Lys (P < 0.005). Finally, to determine whether rats will alter their selection to whole protein-based diets, rats were adapted to 25% wheat gluten diets supplemented with 0.03-0.21% Lys. Rats selected the AD over a diet containing as little as 0.09% less supplemental Lys by d 4 of the trial (P < 0.05). We conclude that rats are sensitive to changes as small.
       as 0.01% in dietary Lys concentration, but that sensitivity requires prior adaptation to Lys-deficient diets.

AB:   In Exp. 1, 72 Targhee lambs (initial BW 22.1 +/- .3 kg) were used to determine the effects of energy source (alfalfa pasture vs limit-fed, all-concentrate) and ionophore addition on performance, visceral organ mass, and carcass characteristics. There were no differences (P > .10) in ADG or gain/feed due to ionophore supplementation. Lambs that grazed alfalfa had greater (P < .05) liver, omasum, abomasum, small intestine, cecum, and large intestine weights than did lambs fed the concentrate diet. Lambs fed the concentrate diet had greater (P < .01) hot carcass weights, larger (P < .01) loin eye areas, and greater (P < .001) dressing percentages than lambs that grazed alfalfa. In Exp. 2, lambs offered the concentrate diet had greater (P < .001) DM and OM digestibilites than lambs offered alfalfa (89.5 and 91.1 vs 72.4 and 72.2%, respectively) Apparent and true N digestibilities were greater (P < .001) for the concentrate diet than for alfalfa (90.9 and 101.7 vs 77.7 and 91.9% respectively) Likewise, grams of N retained per day were twice as great (P < .001) with the concentrate diet than with alfalfa (14.9 vs 6.0 g/d). The greater visceral organ mass and resulting increases in energy and protein requirements in lambs that grazed alfalfa were probably responsible for the lesser hot carcass weight and dressing percentage compared with lambs fed 100% concentrate.

AB:   A clone encoding a proline-rich protein (ZmPRP) has been obtained from maize root by differential screening of a maturing elongation root cDNA library. The amino acid sequence deduced from the full-length cDNA contains a putative signal peptide and a highly repetitive sequence containing the PEPK motif, indicating that the ZmPRP mRNA may code for a cell wall protein. The PEPK repeat is also found in a previously reported wheat sequence but differs from the repeated sequences found in hydroxyproline-rich glycoproteins (HRGP) and in dicot proline-rich proteins (PRP). In the maize genome, the ZmPRP protein is encoded by a single gene that is expressed in maturing regions of the root, in the hypocotyl and in the pericarp. In these organs, the ZmPRP mRNA accumulates in the xylem and surrounding cells, and in the epidermis. No ZmPRP mRNA was found in the phloem. The pattern of mRNA accumulation is very similar to the one observed for genes coding for proteins involved in lignin biosynthesis and, like most cell wall proteins, ZmPRP synthesis is also induced by wounding. These data support the hypothesis that ZmPRP is a member of a new class of fibrous proteins involved in the secondary cell wall formation in monocot species.

AB:   Although maize endosperm undergoes programmed cell death during its development, it is not known whether this developmental feature is common to cereals or whether it arose inadvertently from the selection process that resulted in the enlarged endosperm of modern maize. Examination of wheat endosperm during its development revealed that this tissue undergoes a programmed cell death that shares features with the maize program but differs in some aspects of its execution. Cell death initiated and progressed stochastically in wheat endosperm in contrast to maize where cell death initiates within the upper central endosperm and expands outward. After a peak of ethylene production during early development, wheat endosperm DNA underwent internucleosomal fragmentation that was detectable from mid to late development. The developmental onset and progression of DNA degradation was regulated by the level of ethylene production and perception. These observations suggest that programmed cell death of the endosperm and regulation of this program by ethylene is not unique to maize but that differences in the execution of the program appear to exist among cereals.

AB:   Expression patterns of chitinase transcripts induced by N-acetylchitooligosaccharide elicitor were analyzed by northern blot hybridization in order to reveal a signal transduction pathway leading to the activation of class I chitinase genes (Cht-1 and Cht-3), which may play an important role in producing N-acetylchitooligosaccharide elicitor. The transcription level of both genes was enhanced in response to N-acetylchitooligosaccharides larger than pentaose at subnanomolar concentrations. These structure and dose dependencies were consistent not only with those for a 75 kDa high-affinity binding protein for N-acetylchitooligosaccharide elicitor in the plasma membrane, but also with other series of cellular responses including phytoalexin production and the expression of elicitor-responsive genes (EL2, EL3). Therefore, the elicitor signal to evoke these cellular responses including the activation of the chitinase genes could be common and transmitted into cells through the 75 kDa protein. However, the signal transduction pathway for the activation of the chitinase genes appeared to diverge from those for the other elicitor-responsive genes shortly after the signal perception. It was shown that the induction of chitinase expression by N-acetylchitooligosaccharide would require protein phosphorylation, but not de novo protein synthesis. The oxidative burst was demonstrated not to be necessary for transcriptional induction of the all four elicitor-responsive genes (Cht, PAL, EL2, FL3) by N-acetylchitooligosaccharide.

AB:   The purpose of this work was to determine the frequency of infection by fungal endophytes in Festuca rubra plants from Mediterranean permanent grasslands (dehesas). Plants infected with the fungal endophyte Epichloe festucae were detected in all twenty-seven populations studied in the province of Salamanca, Spain. Infection frequencies in six selected populations ranged from 44% to 92% (average, 70%) of the plants. Infected plants were almost always symptomless. These results suggest that the association between E. festucae and F. rubra is common and occurs at a high frequency in Mediterranean permanent grasslands.

AB:   The effect of management of maize residues on the population of insects inimical to the establishment of alfalfa, Medicago sativa L., was examined 1 month after sowing. Alfalfa was sown in early and late April, and late May for 3 consecutive years in Centre County, Pennsylvania, USA. The sowings were made by conservation tillage (direct drilled into maize residue with minimal disturbance of soil) into three different maize residues after (1) silage, (2) silage-plus-winter rye cover and (3) grain. A fourth sowing was by conventional tillage (spring ploughing and harrowing maize residue) after grain. A pesticide, carbofuran (granular formulation) was applied at sowing to half of the plots. Methiocarb bait, a molluscicide, was applied as a split application to the same plots, one-half at sowing and the remainder 2 weeks later. Alfalfa plots in the silage-plus-rye maize residues were colonized with fewer insects than the other residue treatments. Excessive growth of rye in early spring that was not successfully suppressed by herbicide treatment produced vigorous rye plants and fewer alfalfa seedlings. Consequently, silage plus rye had the lowest yield of alfalfa in early April sowings in 2 out of 3 years. Insects known to feed on alfalfa, such as tarnished plant bugs, Lygus lineolaris (Palsot de Beauvois), the plant bug, Plagiognathus politus Uhler, pea aphids, Acyrthosiphon pisum (Harris), and meadow spittlebugs, Philaenus leucophthalmus spumarius (L.), were collected by sweep net 1 month after sowing and less often in the silage-plus-rye treatment. These species were present in greater numbers in the other maize residues that had significantly more alfalfa.
       forage. The insidious flower bug, Orius insidious (Say), and a damsel bug, Nabis americoferus Carayon, were collected in significantly greater numbers in the early April sowings, which corresponded with the peak populations of pea aphid. The potato leafhopper, Empoasca fabae (Harris), was most abundant in plots sowed in late April or late May. Pesticide treatment applied at the time of sowing had very little effect on numbers of insects collected by sweep net 1 month later in 1986 and 1988. However, pesticide treatment significantly increased yield by 280 kg ha-1 in 1987, even though sweep net collections of insects were not reduced by the pesticide treatment. Therefore, the beneficial effects of the pesticide could not be explained on the basis of the insects collected. The highest yields of alfalfa were obtained from the early April sowing into maize residues. This coincided with the time when the majority of alfalfa pests were less abundant than in later sowings; fewer pests were found on the sowings into silage-plus-rye residue. Also, when the rye forage yield was combined with the alfalfa yield, this became the most productive system.

AB:   The increased seed size of induced polyploid forms has been an important component of improved seedling vigour of small-seeded pasture species. Nitrous oxide was used to produce an octoploid form of the F3 generation of a cross between the closely related tetraploid cultivars, Uneta and Australian phalaris (Phalaris aquatica L.; 2n = 28). A high degree of recovery of octoploid plants (30%) was attained by nitrous oxide treatment. Increases in seed weight, glume length, stomatal guard cell length and pollen grain diameter of 13-84% were recorded in glasshouse grown plants of the octoploid compared with the tetraploid parent population. In a field experiment the superior establishment of the octoploid compared with the tetraploid was interpreted as evidence of the better establishment capacity of the octoploid from deep placement of the seed. However, there was a greater loss of octoploid seedlings over summer, and a greater reduction in the basal area of the sward under continuous grazing than in the tetraploid. Although the octoploid swards produced significantly less phalaris dry weight than the tetraploid in exclosures, the total herbage dry weight of the two types was not significantly different in three of four cuts taken over 2 years. This result supports the view that the more erect, sparsely tillered growth habit of the octoploid phalaris is conducive to the productivity of other sward components.

AB:   Forage crops in Mediterranean environments are characterized by variable seed and forage production. Knowledge of the effects of agronomic factors on annual clovers grown in pure stand and in association with grasses is essential for their effective exploitation of the available environmental resources. Herbage and seed production were evaluated in southern Italy in an experiment with winter annual forage crops during the years 1992-95. Clovers (Trifolium alexandrinum L., berseem; T. incarnatum L., crimson; T. resupinatum L., Persian; and T. squarrosum L., squarrosum) and graminaceous forage crops (Hordeum vulgare L., barley; and Lolium multiflorum Lam., Italian ryegrass) were used to examine the agronomic effects of irrigation and harvest management. The clovers were evaluated in pure stand and in mixture, whereas the graminaceous species were evaluated only in mixtures. The mixtures were sown in alternating, equally spaced rows. The parameters evaluated were forage dry-matter yield, seed yield and its components. The results showed wide differences in forage production between clovers in pure stands and in binary mixtures. Mean dry-matter production from forage harvest of pure stands of irrigated clovers taken when 10-15% of the stems were flowering yielded 4(.)36 t ha-1, that is 0(.)67 and 0(.)55 of that of irrigated mixtures of clovers with either Italian ryegrass or barley, respectively, harvested when 10-20% of the graminaceous components were at the heading stage. The forage yield of non-irrigated pure stands of clovers was 0(.)60 of that of irrigated plots, whereas non-irrigated mixtures yielded 0(.)82 and 0(.)86 of that the irrigated treatments for Italian ryegrass or barley mixtures. The.
       mean seed yield of non-irrigated pure stands of the clovers was 0(.)51 of that of irrigated stands, which yielded 451 kg ha-1. Persian clover gave the highest seed yields (732 kg ha-1 under irrigation). These higher yields were related to a higher number of fructiferous organs per stem in Persian clover. When a forage harvest had previously been taken on irrigated clover plots, the subsequent mean seed yields were greatly reduced to 0(.)76 for berseem and 0(.)21 for Persian clover and were almost negligible for crimson and squarrosum clover. When irrigated and grown in mixtures with Italian ryegrass, only berseem produced a worthwhile yield of 0(.)36 compared with that of pure clover taken for seed without a forage harvest; mixtures with barley gave yields of 0(.)71, 1(.)07 and 0(.)20 for berseem, crimson and Persian clovers, respectively, compared with seed yield from uncut pure clover.

AB:   The effects of NH4(+)-N, NO3(-)-N or urea-N addition on N uptake by perennial ryegrass (Lolium perenne), 15N recovery and pH of four limed and unlimed soils were determined in a pot experiment over 10 weeks. The best form of N in terms of herbage N uptake and fertilizer recovery differed between the soils. Recovery of applied 15N in herbage was greatest for the soil with the lowest pH and highest organic matter content, and overall recovery in the soil-plant system was influenced more by soil type than by N form. There was always an apparent mineralization of soil N when perennial ryegrass was present. Soil pH changes ranged from +0(.)11 to -0(.)58 units for the unlimed soils and from +0(.)03 to -1(.)06 units for the limed soils. The use of NO3(-)-N rather than NH4(+)-N or urea-N avoided further acidification. Lime increased herbage N only from the soils with the lowest pH values. Although the acidifying effect of NH4(+)-fertilizer was alleviated, Liming may increase nitrification and possibly N loss via denitrification and/or leaching in the field. The major influence of soil type on herbage N uptake, pH response to the treatments and fertilizer recoveries implies that liming and fertilizer N management decisions should consider soil characteristics, such as organic matter, clay contents and pH.

AB:   To represent nitrogen cycling in a low input grass/legume pasture system, a previously developed, weather-driven grass/white clover growth model has been adapted to become the crop growth component of the soil nitrogen dynamics model SOILN. This provides a means of simulating nitrogen uptake by a grass/white clover crop, an important component of the overall nitrogen balance in low-input grassland systems. Crop growth is represented by a photosynthesis equation adapted to take account of competition between the two crops for resources of light, water and nitrogen in the soil. Water shortage is represented by linked simulations with the soil water and heat model SOIL, and nitrogen shortage by links with the SOILN model. Nitrogen fixation has been introduced according to an equation for potential fixation reduced by environmental factors, particularly temperature. Transfer of nitrogen-rich clover plant material to the soil nitrogen pools of SOILN (from where it becomes available as a nutrient for grass) is also represented. The model is tested by comparing simulated cut crop yields and nitrogen content of cut material with measured data from perennial ryegrass/white clover at a test site. Soil nitrogen processes in the model are tested by comparing simulated and measured nitrate in drainflows. Apart from some discrepancies between simulated and measured results attributable to the inherent instability of a mixed crop system, agreement is reasonable by the standards of biological system models, indicating that the combined model gives a realistic representation of carbon and nitrogen processes in grassland with a grass, legume mixed crop.

AB:   The expected reduction in the use of fertilizer nitrogen (N) on grassland in the Netherlands has led to renewed interest in white clover. Therefore, the performance of a newly sown perennial ryegrass/white clover sward on clay soil was assessed during 4 consecutive years. The experiment consisted of all combinations of two defoliation systems, i.e. one or two silage cuts per year (S1, S2), spring N application rate, i.e. 0 or 50 kg ha-1 year-1 (N0, N50), and the management system, i.e. rotational grazing and cutting, or cutting only (RGC, CO). The overall mean white clover cover was 30%. All treatments affected white clover cover, which was 8% higher with S2 than with S1 6% higher with N0 than with N50 and 12% higher with CO than with RGC. The overall mean annual dry-matter (DM) yield (13(.)1 t ha-1 year-1) was significantly affected only by the management system: in two relatively wetter years, the annual DM yield was 1(.)19 t ha-1 higher with RGC than with CO, whereas there was no difference in two relatively drier years. Nitrogen application increased the DM yield in the first cut by 7(.)0 kg kg-1 N applied, but had no significant effect on the annual DM yield. Herbage quality was not affected by the experimental treatments. The average in vitro organic matter digestibility was 0.801, and the average crude protein content was 193 g kg-1 DM. With the expected reduction in the use of fertilizer N, perennial ryegrass/white clover swards should be seriously considered as an altemative option to perennial ryegrass swards on these clay soils.

AB:   The objective of this study was to develop a linear programming model to analyze the production schedule of rice seedlings grown in the nursery. The model can help the managers of rice seedling centers in Taiwan to make better production decisions and maximize profit (all monetary units are expressed in US dollars). To verify the model, a rice seedling center was chosen for analysis of the first rice crop in 1997. The results show that the cost is about $51,856 yielding a profit of about $21,861 to supply 91,385 boxes of seedlings. The maximum number of boxes in the greening field is 4,600. The minimum production in each batch affects the cost significantly. The results show costs of about $41,884 for 4,000 boxes batch(-1), while costs rise to about $56,522 for 6,000 boxes batch(-1). Consequently, using the model to predict the production schedule not only reduces costs but also provides the seedling in the best status for transplanting. The demand quantities of the boxes in each day during the transplanting period can be expressed by a fourth-order polynomial. Here, a demand quantity ranging from 73,928 to 110,892 boxes is generated by the polynomial to analyze the production schedule. The result shows that the production scale could be expanded to about 110,892 boxes with the same hardware. In this status, the profit could be increased to about $26,667, and the cost/profit ratio is 2.35. The relationship between supply quantity scale (x) and greening field size (y) can be calculated by a regression formula (y = 0.4609x + 3.143), where both units are in 10,000 boxes.

AB:   The objectives of this study were: (1) to quantify post-anthesis kernel cytokinin levels in 'Tibet Dwarf', a dwarf wheat (Triticum aestivum L.) that accumulates elevated quantities of leaf cytokinins; and (2) to measure the effects of temperature on kernel cytokinin accumulation and mature kernel mass in this wheat. Post-anthesis kernel cytokinin accumulation was measured in control plants maintained at 25/12 degrees C (day/night) and treated plants which received a 7 d exposure to 35/25 degrees C beginning at anthesis and grown to maturity at 25/15 degrees C. Zeatin (Z), dihydrozeatin (diHZ) and their respective ribosides were the predominant cytokinins detected in control and treated plants. Minimal quantities of isopentenyl adenine-type cytokinins were detected. Kernel cytokinin content peaked within 3 d after anthesis in both groups and returned to baseline levels within 1-2 d. Relative to controls, exposure to high temperature reduced kernel cytokinin content approx. 80% within 1 d after anthesis. Because kernel cytokinin in control Tibet Dwarf plants exceeded that previously measured in other varieties by over 100-fold, the reduced content of treated plants still exceeded that of untreated plants of other varieties. The increased cytokinin content did not enhance thermotolerance. The temperature treatment reduced mature kernel weights approx. 27%, similar to reductions measured in other wheat varieties.

AB:   The effects of soil bulk density and hence strength on two contrasting species of herbaceous annuals, the dicot sunflower (Helianthus annuus L.) and the monocot maize (Zea mays L.), were investigated by comparing the morphology and mechanics of field-grown plants in soil with a low and high bulk density. Soil with a low bulk density had a significantly lower penetration resistance (118 +/- 4(.)4 kPa) than the high bulk density soil (325 +/- 12(.)2 kPa; P < 0(.)0001). Soil strength affected shoot and root systems of both species but had no significant effect on shoot height. In both species roots were thicker closer to the stem base in strong soil compared to those in weaker soil. Sunflower tap-roots growing in strong soil tapered more rapidly than those in weak soil. Only in maize, however, were roots growing in weak soil stiffer than those in strong soil. Despite only small absolute differences in the penetration resistance of the soil both species growing in strong soil had greater anchorage strength than those in weak soil. As a consequence more plants in weak soil lodged compared with those growing in strong soil. This study shows that plants can, to a small extent, respond to changes in soil strength, but that changes do not appear to compensate fully for alterations in soil conditions. Furthermore it may be possible, by manipulating soil strength, to control lodging.

AB:   The purpose of this work was to evaluate the stability of a countercurrent steep system to ensure that variables, including temperature, pump flow rate and steepwater profiles remain stable during long periods of operation. Four runs of a laboratory-scale continuous countercurrent steep system were used to evaluate its thermal and mechanical stability. One run was started with fresh steepwater while the other three were inoculated with light steepwater obtained from a wet-milling plant. Variables, such as steep temperature, steepwater recycle rate and light steepwater draw rate, were monitored. Steepwater characteristics, including pH, SO(2) concentration, lactic acid concentration and steepwater solids content were determined. Six to eight days were required for all of the steepwater variables (pH, SO(2) and lactic acid concentration and steepwater solids content) to reach steady state when light steepwater from a plant was used to inoculate the system. When fresh steepwater was used, 12 d were needed. The average steep temperature of the 16 tanks during 16 d of continuous operation was 50 +/- 1 degree C with a setpoint of 50 +/- 2 degrees C. The average pump flow rate for the 8 pumps was 5.0 +/- 0.1 mL/s when the setpoint was 5.0 mL/s. The average light steepwater draw rate over nine days was 593 +/- 49 mL/kg when the setpoint was 600 mL/kg. Corn steeped in this system was wet-milled and product yields were reproducible.

AB:   Potato and wheat plants were grown for 50 d at 400, 1000 and 10000 micromol mol(-1) carbon dioxide (CO(2)), and sweetpotato and soybean were grown at 1000 micromol mol(-1) CO(2) in controlled environment chambers to study stomatal conductance and plant water use. Lighting was provided with fluorescent lamps as a 12h photoperiod with 300 micromol m(-2) s(-1) PAR. Mid-day stomatal conductances for potato were greatest at 400 and 10000 micromol mol(-1) and least at 1000 micromol mol(-1) CO(2). Mid-day conductances for wheat were greatest at 400 micromol mol(-1) and least at 1000 and 10000 micromol mol(-1) CO(2).  Mid-dark period conductances for potato were significantly greater at 10000 micromol mol(-1) than at 400 or 1000 micromol mol(-1), whereas dark conductance for wheat was similar in all CO(2) treatments. Temporarily changing the CO(2) concentration from the native 1000 micromol mol(-1) to 400 micromol mol(-1) increased mid-day conductance for all species, while temporarily changing from 1000 to 10000 micromol mol(-1) also increased conductance for potato and sweetpotato. Temporarily changing the dark period CO(2) from 1000 to 10000 micromol mol(-1) increased conductance for potato, soybean and sweetpotato. In all cases, the stomata responses were reversible, i.e. conductances returned to original rates following temporary changes in CO(2) concentration. Canopy water use for potato was greatest at 10000, intermediate at 400, and least at 1000 micromol mol(-1) CO(2), whereas canopy water use for wheat was greatest at 400 and similar at 1000 and 10000 micromol mol(-1) CO(2). Elevated CO(2) treatments (i.e. 1000 micromol mol(-1)) resulted in increased plant biomass.
       for both wheat and potato relative to 400 micromol mol(-1), and no injurious effect were apparent from the 10000 micromol mol(-1) treatment. Results indicate that super-elevated CO(2) (i.e. 10000 micromol mol(-1)) can increase stomatal conductance in some species, particularly during the dark period, resulting in increased water use and decreased water use efficiency.

AB:   We investigated spikelet development in four distantly related species of the grass tribe Andropogoneae to determine whether spikelet development and the formation of unisexual florets are uniform throughout the tribe. We studied development in Bothriochloa bladhii, Coelorachis aurita, Heteropogon contortus, and Hyparrhenia hirta, and compared these with Panicum, a member of the sister tribe Paniceae. Many aspects of spikelet development in the species we have studied correlate with what is already known for Tripsacum and maize (both Andropogoneae), despite variation in how unisexual florets are distributed on the plant. The formation of unisexual spikelets is also uniform. All florets initiate both pistil and stamen primordia. In florets destined to be male, cell death occurs in the subepidermal layers of the gynoecium after the formation of a gynoecial ridge. In florets destined to be female, there is no apparent cell death in the stamens, but growth ceases after anther formation. The similarity in spikelet development and the formation of unisexual florets point to a common genetic mechanism for sex determination throughout the Andropogoneae and possibly the entire Panicoideae. Use of a cell death pathway to cause gynoecial abortion may be the basis of one morphological character that defines the subfamily.

AB:   Dryers are rated based on the average moisture content, with no consideration to the range in single-kernel moisture contents. The moisture content variation in lots of corn dried in three commercial dryer types was measured along with the grain quality (as indicated by the percentage of stress-cracked kernels). Corn exiting a high-temperature dryer regardless of the type, had a standard deviation in the moisture content of the individual kernels of 3 to 5%, but this figure decreased to about 1% within three days. The corn dried in the concurrent flow dryers showed the fewest stress cracks, that dried in the crossflow dryers the highest percentage of stress cracks.

AB:   Two statistical and one neural network classifiers were applied and empirically compared for the classification cereal grain kernels (e.g., Canadian Western Red Spring (CWRS) wheat, Canadian Western Amber Durum (CWM)) wheat, barley, rye, and oats) and for the classification of healthy and six types of damaged (e.g. broken, grass-green/green-frosted, black-point/smudge, mildewed, heated, and bin/fire-burnt) CWRS wheat kernels, using selected morphological and color features extracted from the grain sample images. For the classification of cereal grain kernels and the classification of healthy and damaged CWRS wheat kernels, the k-nearest neighbor statistical classifier and the multilayer neural network (MNN) classifier gave similar and the best classification results. Using a k-nearest neighbor classifier with a selected set of 15 morphological and 13 color features, the average classification accuracies were 98.2, 96.9, 99.0, 98.2, and 99.0% for CWRS wheat, CWAD wheat, barley, rye, and oats, respectively, when trained and tested with three different training and testing data sets. Using a k-nearest neighbor classifier with a selected set of 24 color and four morphological features, the average classification accuracies were 92.5 (healthy), 90.3 (broken), 98.6 (mildewed), 99.0 (grass- green/green-frosted), 99.1 (black-point/smudged), 97.5 (heated), and 100.0% (bin/fire-burnt), respectively, when trained and tested with three different training and testing data sets. The classification accuracies achieved using a parametric classifier were lower than the classification accuracies achieved using both the k-nearest neighbor and the MNN classifiers.

AB:   Fatty acids in the diet are readily incorporated into lipids in various tissues. However, it is not clear whether all tissues have the same level of incorporation. Second, (n-6) unsaturated fatty acids increase the fluidity of membranes, but this has not been shown for (n-3) fatty acids. In this study, we measured the incorporation of (n-6) and (n-3) fatty acids into erythrocyte membrane lipids and studied their effects on the fluidity of erythrocyte membranes. One group of female miniature swine was made hypercholesterolemic by feeding the swine cholesterol and lard for 2 mo; the other group served as controls and was fed a stock diet. Both groups were then fed either corn oil or menhaden oil or a mixture of the two for 23 additional weeks. Blood was collected at 0, 2, 4, 12 and 23 wk after initialization of the experimental diets, and fatty acid composition of phospholipids was assessed. Membrane phospholipids of pigs fed menhaden oil had elevated (n-3) fatty acids (20:5 and 22:6), and lower 18:2 than those fed corn oil. There was no difference in 20:4 content. The fatty acid changes occurred as early as 2 wk after consumption of the corn oil or menhaden oil in pigs previously fed a stock diet, but it took longer in pigs previously fed lard + cholesterol, indicating residual effects of pretreatment. Menhaden oil increased anisotropy (indicating decreased fluidity) more than corn oil for the nonpolar probe diphenylhexatriene (DPH) at earlier time points, but not at 23 wk. Erythrocyte membrane fluidity was significantly related to membrane polyunsaturate content, with (n-6) fatty acids having a greater influence than (n-3) fatty acids. A comparison of the present red blood cell fatty.
       acid compositions with brain synaptosome fatty acid compositions for the same animals showed poor correlations for some of the fatty acids. There was no significant direct relationship between docosahexaenoate (DHA) concentrations in erythrocyte membranes with DHA concentrations in brain synaptosomes from cerebellum, forebrain and caudate nucleus.

AB:   The domestication of all major crop plants occurred during a brief period in human history about 10,000 years ago. During this time, ancient agriculturalists selected seed of preferred forms and culled out seed of undesirable types to produce each subsequent generation. Consequently, favoured alleles at genes controlling traits of interest increased in frequency, ultimately reaching fixation. When selection is strong, domestication has the potential to drastically reduce genetic diversity in a crop. To understand the impact of selection during maize domestication, we examined nucleotide polymorphism in teosinte branched1, a gene involved in maize evolution. Here we show that the effects of selection were limited to the gene's regulatory region and cannot be detected in the protein-coding region. Although selection was apparently strong, high rates of recombination and a prolonged domestication period probably limited its effects. Our results help to explain why maize is such a variable crop. They also suggest that maize domestication required hundreds of years, and confirm previous evidence that maize was domesticated from Balsas teosinte of southwestern Mexico.

AB:   A MADS family gene, OsMADS6, was isolated from a rice (Oryza sativa L,) young flower cDNA library using OsAMDS1 as a probe. With this clone, various MADS box genes that encode for protein-to-protein interaction partners of the OsMADS6 protein were isolated by the yeast two-hybrid screening method. On the basis of sequence homology, OsMADS6 and the selected partners can be classified in the APETALA1/AGAMOUS-LIKE9 (AP1/AGL9) family. One of the interaction partners, OsMADS14, was selected for further study. Both genes began expression at early stages of flower development, and their expression was extended into the later stages. In mature flowers the OsMADS6 transcript was detectable in lodicules and also weakly in sterile lemmas and carpels, whereas the OsMADS14 transcript was detectable in sterile lemmas, paleas/lemmas, stamens, and carpels. Using the yeast two-hybrid system, we demonstrated that the region containing of the 109th to 137th amino acid residues of OsMADS6 is indispensable in the interaction with OsMADS14. Site-directed mutation analysis revealed that the four periodical leucine residues within the region are essential for this interaction. Furthermore, it was shown that the 14 amino acid residues located immediately downstream of the K domain enhance the interaction, and that the two leucine residues within this region play an important role in that enhancement.

AB:   The starch granules of hexaploid wheat (Triticum aestivum) contain a group of three proteins known as SGP-1 (starch granule protein-1) proteins, which have apparent molecular masses of 100, 108, and 115 kD. The nature and role of these proteins has not been defined previously. We demonstrate that these polypeptides are starch synthases that are present in both the starch granule and the soluble fraction at the early stages of wheat endosperm development, but that are exclusively granule bound at mid and late endosperm development. A partial cDNA clone encoding a fragment of the 100-kD protein was obtained by screening a wheat endosperm cDNA expression library using monoclonal antibodies. Three classes of cDNA were subsequently isolated from a wheat endosperm cDNA library by nucleic acid hybridization and were shown to encode the 100-, 108-, and 115-kD proteins. The cDNA sequences are highly homologous to class II starch synthases and have the highest homology with the maize SSIIa (starch synthase IIa) gene. mRNA for the SGP-1 proteins was detected in the leaf, pre-anthesis florets, and endosperm of wheat and is highly expressed in the leaf and in the grain during the early to mid stages of development. We discuss the roles of the SGP-1 proteins in starch biosynthesis in wheat.

AB:   We describe here the biochemical characteristics of the hcf44 and hcf47 (high chlorophyll fluorescence) mutants of maize (Zea mays L.). Both mutants were sensitive to high light intensities, exhibiting reduced growth and fluorescence intensity. Electron transport through the mutants' photosystem (PS)I and PsII reaction centers was reduced and NADP+ photoreduction was absent. Western analysis revealed that the hcf44 mutant was missing some or all of the PsaC, PsaD, and PsaE polypeptides of the PSI reaction center, and reverse transcriptase-polymerase chain reaction demonstrated that this loss was the result of a posttranscriptional event. The hcf47 mutant had reduced levels of many PSI and PSII polypeptides. These data indicate a possible defect in the synthesis or assembly of the PsaC subunit in the hcf44 mutant, whereas the hcf47 mutant may have a more general defect in the biogenesis of photosynthetic membranes. Our results demonstrate the coordinated assembly of the peripheral proteins into the PSI complexes of higher plants and demonstrate the in vivo requirement of PsaC, PsaD, and PsaE subunits for the function of PSI in higher plants.

AB:   We examined the mechanism of synthesis in vitro of (1 leads to 3),(1 leads to 4)beta-D-glucan (beta-glucan), a growth-specific cell wall polysaccharide found in grasses and cereals. beta-Glucan is composed primarily of cellotriosyl and cellotetraosyl units linked by single (1 leads to 3)beta-linkages. The ratio of cellotriosyl and cellotetraosyl units in the native polymer is strictly controlled at between 2 and 3 in all grasses, whereas the ratios of these units in beta-glucan formed in vitro vary from 1.5 with 5 micrometer UDP-glucose (Glc) to over 11 with 30 mM substrate. These results support a model in which three sites of glycosyl transfer occur within the synthase complex to produce the cellobiosyl-(1 leads to 3)-D-glucosyl units. We propose that failure to fill one of the sites results in the iterative addition of one or more cellobiosyl units to produce the longer cellodextrin units in the polymer. Variations in the UDP-Glc concentration in excised maize (Zea mays) coleoptiles did not result in wide variations in the ratios of cellotriosyl and cellotetraosyl units in beta-glucan synthesized in vivo, indicating that other factors control delivery of UDP-Glc to the synthase. In maize sucrose synthase is enriched in Golgi membranes and plasma membranes and may be involved in the control of substrate delivery to beta-glucan synthase and cellulose synthase.

AB:   Saline-soluble glycinins and insoluble glutelins are the major storage proteins in soybean (Glycine max) and rice (Oryza sativa), respectively. In spite of their differences in solubility properties, both proteins are members of the 11S globulin gene family based on their similarities in primary sequences and processing of the coded protein. Wild-type and methionine-modified glycinin coding sequences were expressed in transgenic rice plants under the control of the rice glutelin GluB-1 promoter. Glycinins were specifically synthesized in the endosperm tissue and co-localized with glutelins in type II protein bodies. They assembled into 7S and 11S species, similar to what was observed in developing soybean seeds. This pattern was quite different from that displayed by the rice glutelins in untransformed plants, in which processed subunits sedimenting at 2S were apparent. In glycinin-expressing transgenic plants, however, glutelins were observed sedimenting at 7S and 11S with lesser amounts in the 2S region. A portion of the glycinins was also found associated in the insoluble glutelin fraction. Renaturation experiments suggested that the hybrid glycinin-glutelin oligomers were formed through specific interactions. Overall, these results indicate that despite significant differences in the assembly of soybean glycinin and rice glutelin, both proteins can assemble with each other to form soluble hexameric oligomers or insoluble aggregates.

AB:   The genes AV1, AV10, and Z1 encode proteins that accumulate during oat seed development. In developing endosperm of Avena sativa (cultivated oat), AV1, AV10 and Z1 mRNAs reach maximal levels midway through seed development but fall to very low levels in mature seeds. Similarly, mRNAs for these proteins peak during endosperm development of Avena fatua (wild oat) and are later degraded. However, during late maturation of A.fatua seeds, populations of mRNA fragments shorter than the intact transcripts accumulate as the full-length transcripts decline in abundance. The smaller RNA molecules, which are apparently long-lived decay intermediates, are derived randomly from the entire transcripts and are most likely not generated by cleavage at precisely defined sites. Other A. fatua endosperm mRNAs that are degraded during late seed development, such as those for ADP glucose pyrophosphorylase and starch synthase, do not produce detectable decay intermediates. Decay intermediates of AV1 and Z1 mRNAs persist at high levels during late seed development of two other undomesticated oat species, Avena strigosa and Avena barbata. The persistence of decay intermediates for these endosperm mRNAs in wild grass species may represent a model system for studying RNA decay process in plant tissues.

AB:   We have used differential display to detect altering mRNA levels in response to desiccation and rehydration in leaves of the desiccation tolerant grass Sporobolus stapfianus. One of the RT-PCR products identified was used to isolate a cDNA of 999 bp which encodes a protein of 210 amino acids (predicted size 23 kDa). This protein displays considerable sequence similarity to mammalian and plant Rab2, a small GTP-binding protein, possessing several conserved motifs common to these regulatory proteins. Sporobolus Rab2 was expressed in Escherichia coli yielding a protein with an apparent molecular mass of ca. 30 kDa which was shown to have the ability to bind GTP. Rab2 transcript accumulated early in response to a decrease in relative water content (RWC) and remained high even in dried leaves. Rehydration of desiccated leaves resulted in a decrease in levels within 3 h of rewetting, with a brief increase at ca. 12 h. Accumulation of Rab2 transcript was also evident during drying and rehydration of the roots of S. stapfianus, as well as in leaves of the desiccation-sensitive grass Sporobolus pyramidalis. Earlier work on S. stapfianus concluded that the plant hormone ABA has little effect on inducing desiccation tolerance, however Rab2 transcript does exhibit a small increase in accumulation in response to exogenous ABA. A possible role for Rab2 with respect to desiccation tolerance and damage repair is discussed.

AB:   Geminiviruses encode a few proteins and depend on cellular factors to complete their replicative cycle. As a way to understand geminivirus-host interactions, we have searched for cellular proteins which interact with viral proteins. By using the yeast two-hybrid technology and the wheat dwarf geminivirus (WDV) RepA protein as a bait, we have isolated a family of proteins which we termed GRAB (for Geminivirus Rep A-binding). We report here the molecular characterization of two members, GRAB1 and GRAB2. We have found that the 37 C-terminal amino acids of RepA are required for interaction with GRAB proteins. This region contains residues conserved in an equivalent region of the RepA proteins encoded by other viruses of the WDV subgroup. The N-terminal domain of GRAB proteins is necessary and sufficient to interact with WDV RepA. GRAB proteins contain an unique acidic C-terminal domain while their N-terminal domain, of ca. 170 amino acids, are highly conserved in all of them. Interestingly, this conserved N-terminal domain of GRAB proteins exhibits a significant amino acid homology to the NAC domain present in proteins involved in plant development and senescence. GRAB1 and GRAB2 mRNAs are present in cultured cells and roots but are barely detectable in leaves. GRAB expression inhibits WDV DNA replication in cultured wheat cells. Our studies highlight the importance that the pathway(s) mediated by GRAB proteins, as well as by other NAC domain-containing proteins, might have on geminivirus DNA replication in connection to plant growth, development and senescence pathways.

AB:   A complete set of nine primary trisomics (2n + 1) for cv. 'Yugu No. 1' of foxtail millet, Setaria italica (L.) Beauv. (2n = 2x = 18), was identified cytologically from progenies derived from crosses between autotriploids (2n = 3x = 27) and their diploid counterparts. Five autotriploid plants were identified from 2100 seedlings derived from 4x-2x crosses; the reciprocal crosses (2x-4x) failed to produce autotriploids. Autotriploids grew vigorously and were morphologically very similar to diploids. The primary trisomics (2n = 2x = 19) constituted approximately equal to 32.5% of the total progeny from the 3x-2x crosses, whereas 59.8% of the descendants were aneuploids with chromosome numbers ranging from 20 (double trisomics and tetrasomics) to 37 (2n = 4x + 1; or autotetraploid with one additional chromosome). The nine primary trisomics identified were self-fertile; seven had characteristic morphology, whereas trisomics VIII and IX resembled the disomics. The seed set for trisomic V was the lowest (20%), and trisomic VIII the highest (74%). Other aneuploids with 20 or more somatic chromosomes were either self-sterile or partially fertile with various, but low, levels of seed set. Each of the primary trisomics showed its unique transmission rate when self-pollinated; trisomic IX had the highest (45.8%), whereas trisomic V had the lowest (19.6%) transmission rate.

AB:   Variability for desirable alleles within elite breeding populations is a requirement for long-term genetic improvement. Changes in genetic diversity were evaluated in a recurrent selection programme for enhanced grain yield in oat, Avena sativa L., using coefficient of parentage (r(p)) and restriction fragment length polymorphism (RFLP) based genetic similarity (s) estimates. Both r(p) and s increased during seven cycles of recurrent selection, indicating a reduction in the level of genetic diversity within the population. The relationship between genetic diversity and agronomic performance was also examined. Genetic similarity measures were poor predictors of the near-homozygous progeny performance and general and specific combining ability effects for three agronomic traits in the recurrent selection programme. In addition, there was no apparent trend for preferential selection of progeny from either more similar or more diverse parents within a given cycle of selection. The overall reduction in genetic diversity in this population has not affected selection response for grain yield. Variability remaining at important loci or de novo variation are possible explanations for the continued selection progress.

AB:   Pyrenophora graminea is a seed-borne pathogen and the causal agent of the barley leaf stripe disease. Our aim is to study the genetic basis of barley resistance to leaf stripe. A qualitatively acting resistance factor has been identified in the cultivar 'Vada' and the partial resistance of the cultivar 'Proctor' to a P. graminea isolate have been demonstrated to be dominated by a major quantitative trait locus (QTL), mapped on barley chromosome 1. Map colinearity between the leaf stripe 'Proctor' resistance QTLs, 'Vada' resistance to leaf stripe and other disease resistance loci have been investigated in this work using molecular markers. Moreover, since inoculation of barley rootlets by the fungus had been shown to induce the accumulation of several PR (pathogen-related) mRNA families, seven barley PR genes have been mapped as RFLPs, and one assigned to a chromosome arm via ditelosomic analysis to verify possible map associations between the known leaf stripe resistance loci, resistance loci towards other seed-borne pathogens and defense gene loci.

AB:   Multi-environment trials (METs) are used in plant breeding programmes to evaluate genotypes (lines/families) as a basis for selection on expected performance (yield and/or quality) in a target population of environments (TPE). When a large component of the genotype-environment (G x E) interactions results from crossover interactions, samples of environments in METs that deviate from the TPE provide a suboptimal basis for selection of genotypes on performance expected in the TPE. To adjust for the negative effects of these deviations, a selection strategy that weights the data from the MET according to their expected frequency of occurrence in the TPE (i.e. a weighted selection strategy) was investigated. Computer simulation methodology was used to obtain preliminary information on the weighted selection strategy and compare it to the traditional unweighted selection strategy for a range of MET scenarios and G x E interaction models. The evaluation of the weighted selection strategy was conducted in context with the germplasm enhancement programme (GEP) of the Northern Wheat Improvement Programme in Australia. The results indicated that when the environments sampled in the MET matched those expected in the TPE, the unweighted and weighted selection strategies achieved a similar response to selection in the TPE. However, when the environments sampled in the MET did not match the expectations in the TPE and a large component of the G x E interactions resulted from crossover interactions, the weighted selection strategy achieved a greater response to selection in the TPE. The advantage of the weighted strategy increased as the amount of crossover G x E interaction increased.
       or fewer environments were sampled in the METs.

AB:   The purpose of the present work was to evaluate both oxidative stress and the antioxidant response system in leaves from wheat (Triticum aestivum cv. Buck Poncho) subjected sequentially to drought and watering. Drought was imposed by withholding water until soil water potential reached -2.0 MPa and maintained under those conditions for 24 h. DCFDA oxidation by wheat leaves was not significantly affected by drought, but watering led to an approximately 2-fold increase in DCFDA oxidation rate. However, no significant effect either on lipid radical content or on hydroperoxide content was measured after drought and drought followed by watering. Microsomes isolated from leaves exposed to drought, and from leaves exposed to drought followed by watering, generated a significantly higher amount of hydroxyl radical as compared to microsomes isolated from control leaves, suggesting a higher production of hydroxyl radical in the cellular water-soluble phase, after drought and watering as compared to control values. The content of alpha-tocopherol in wheat leaves was increased 2.4-fold after drought and beta-carotene content was increased by 2.6-fold after drought. Hydration lowered lipid-soluble antioxidant content to control values. Total thiol content was increased by 70% after drought, and watering did not significantly alter the enhanced values. Drought decreased by 28.5% the content of reduced ascorbic acid. Taken as a whole, active species formed at wheat membranes after exposure to moderate water stress, are efficiently removed upon rehydration by reaction with an increased content of alpha-tocopherol and beta-carotene. Moreover, a co-ordinated response involving.
       glutathione reductase activity, thiols and ascorbic acid is triggered to limit free radical dependent effects.

AB:   With the aim of determining the level at which ageing exerts its effect on the expression of alpha-amylase, GA3 regulation of alpha-amylase production was studied in isolated aleurone layers from aged wheat seeds. GA3-induced a-amylase activity was lower in the tissue from aged seeds than in controls. However, the proportion of 35S-methionine incorporated into alpha-amylase was higher in the aged than in control tissue. The pattern of alpha-amylase isoforms was resolved by isoelectric focusing and showed that two isogroups were present with the activity of the high-pl isogroup being higher in the control than in the aged lot. These apparently contradictory results may be explained in terms of differences in isozyme expression. Studies on the expression of alpha-amylase genes indicated a reduction in the level of high-Pl mRNA in aged tissue. Dose-response curves showed lower GA3-responsiveness of aleurone layers from aged seeds as compared to the controls. From these results, it is proposed that the diminished capacity of alpha-amylase production in aleurone from aged seeds is apparently due to a decrease in the expression of the high-pl alpha-amylase genes, and this reduction is associated with a decrease in the response to GA3.

AB:   The proteome is emerging as an important concept of the post-genome era. Powerful nucleic acid approaches (EST, DNA chips, etc.) are still limited because DNA sequences and mRNA levels are not sufficient to predict the structure, function, amount, and activity of the proteins in the cell. The proteome can now be subjected to large-scale analysis, owing to spectacular progress in the techniques of identification of proteins excised from two-dimensional (2-D) gels. In addition, computer-based analysis of 2-D gels makes it possible to quantify the protein spot intensities, which are commonly genetically variable. The loci controlling these variations may be mapped on the genome (PQLs, Protein Quantity Loci). Beyond the interest for regulatory genetics and molecular biology, the PQL methodology can provide an additional tool for the difficult task of identifying QTLs (Quantitative Trait Loci), in the context of the candidate gene approach. The PQL methodology is presented with the example of the phosphoglycerate mutase variations in maize, and the candidate gene/protein approach is illustrated for traits responsive to drought stress.

AB:   Studying the heterogeneity in variation of gene frequency among populations or between generations may be a possible way to detect genomic regions experiencing selection. In order to evaluate this approach, RFLP markers were used to compare the allelic frequencies in wheat populations that had been submitted to natural selection. In 1984, samples of two composite cross populations were distributed in the French network for dynamic management of genetic resources. Since then, all the sub-populations have been cultivated in the same sites with no human selection. The strong differentiation between populations found for agro-morphological traits (earliness, resistance to pathogens, ...) provided evidence of their adaptation to local conditions. The two initial populations and six derived sub-populations cultivated for 10 years in four contrasted sites were studied with RFLP markers. Differentiation between sub-populations based on RFLP diversity was highly significant. Variations of allelic frequencies of the 30 loci scored were found to be much greater than expected under genetic drift only. This led us to conclude that selection greatly influenced the evolution of the populations. Some of the loci clearly presented a higher differentiation than the others. This might indicate that they were genetically linked to other loci polymorphic in the populations and involved in adaptation. However, the effect of one selected gene on a marker, even located very close to the gene, could not be predicted with certainty. Hence, though the populations were predominantly selfing, it seems that initial linkage disequilibriums between markers and selected genes were not strong enough to control closely the evolution of.

AB:   Rice (paddy) and fish yields in concurrent, direct-seeded culture were investigated at the Co Do station located in the Mekong Delta, Vietnam. Three different rice seeding rates (100, 200 and 300 kg ha(-1)) were used in the absence or presence of fish (Oreochromis niloticus (all male). Puntius gonionotus, and Cyprinus carpio). Significantly (P < 0.05) higher paddy and fish yields were obtained at the lowest rice seeding rate. No significant effect of the rice seeding rate on aquatic weed biomass was found, whereas water temperature, dissolved oxygen concentration and pH were significantly (P < 0.05) higher at 100 kg rice seed ha(-1) . The presence of fish resulted in a significant (P < 0.05) reduction of aquatic weed biomass, and significantly (P < 0.05) lower dissolved oxygen and PO(4) concentrations, and higher chlorophyll-a levels in the pond water. Analysis of the results indicated that the effect of rice seeding rate on fish production was most likely to be related to a 'growth effect' resulting from increased availability of oxygen and food. Paddy yields at high seeding densities were affected by mutual shading. A further reduction of rice seeding rate may be feasible for rice-fish farmers, given their limited possibilities for weed control through land preparation (field levelling) and water management.

AB:   We analyzed antioxidative defenses, photosynthesis, and pigments (especially xanthophyll-cycle components) in two wheat (Triticum durum Desf.) cultivars, Adamello and Ofanto, during dehydration and rehydration to determine the difference in their sensitivities to drought and to elucidate the role of different protective mechanisms against oxidative stress. Drought caused a more pronounced inhibition in growth and photosynthetic rates in the more sensitive cv Adamello compared with the relatively tolerant cv Ofanto. During dehydration the glutathione content decreased in both wheat cultivars, but only cv Adamello showed a significant increase in glutathione reductase and  hydrogen peroxide-glutathione peroxidase activities. The activation states of two sulfhydryl-containing chloroplast enzymes, NADP(+)-dependent glyceraldehyde-3-phosphate dehydrogenase  and fructose-1,6-bisphosphatase, were maintained at control levels during dehydration and rehydration in both cultivars. This indicates that the defense systems involved are efficient in the protection of sulfhydryl groups against oxidation. Drought did not cause significant effects on lipid peroxidation. Upon dehydration, a decline in chlorophyll a, lutein, neoxanthin, and beta-carotene contents, and an increase in the pool of de-epoxidized xanthophyll cycle components (i.e. zeaxanthin and antheraxanthin), were evident only in cv Adamello. Accordingly, after exposure to drought, cv Adamello showed a larger reduction in the actual photosystem II photochemical efficiency and a higher increase in nonradiative energy dissipation than cv Ofanto. Although differences in zeaxanthin content were not sufficient to explain the difference in drought.
       tolerance between the two cultivars, zeaxanthin formation may be relevant in avoiding irreversible damage to photosystem II in the more sensitive cultivar.

AB:   Mutant sorghum (Sorghum bicolor [L.] Moench) deficient in functional phytochrome B exhibits reduced photoperiodic sensitivity and constitutively expresses a shade-avoidance phenotype. Under relatively bright, high red:far-red light, ethylene production by seedlings of wild-type and phytochrome B-mutant cultivars progresses through cycles in a circadian rhythm; however, the phytochrome B mutant produces ethylene peaks with approximately 10 times the amplitude of the wild type. Time-course northern blots show that the mutant's abundance of the 1-aminocyclopropane-1-carboxylic acid (ACC) oxidase mRNA SbACO2 is cyclic and is commensurate with ethylene production, and that ACC oxidase activity follows the same pattern. Both SbACO2 abundance and ACC oxidase activity in the wild-type plant are very low under this regimen. ACC levels in the two cultivars did not demonstrate fluctuations coincident with the ethylene produced. Simulated shading caused the wild-type plant to mimic the phenotype of the mutant and to produce high amplitude rhythms of ethylene evolution. The circadian feature of the ethylene cycle is conditionally present in the mutant and absent in the wild-type plant under simulated shading. SbACO2 abundance in both cultivars demonstrates a high-amplitude diurnal cycle under these conditions; however, ACC oxidase activity, although elevated, does not exhibit a clear rhythm correlated with ethylene production. ACC levels in both cultivars show fluctuations corresponding to the ethylene rhythm previously observed. It appears that at least two separate mechanisms may be involved in generating high-amplitude ethylene rhythms in sorghum, one in response to the loss of phytochrome.

AB:   Using monoclonal tubulin and actin antibodies, Al-mediated alterations to microtubules (MTs) and actin microfilaments (MFs) were shown to be most prominent in cells of the distal part of the transition zone (DTZ) of an Al-sensitive maize (Zea mays L.) cultivar. An early response to Al (1 h, 90 micromolar) was the depletion of MTs in cells of the DTZ, specifically in the outermost cortical cell file. However, no prominent changes to the MT cytoskeleton were found in elongating cells treated with Al for 1 h in spite of severe inhibition of root elongation. Al-induced early alterations to actin MFs were less dramatic and consisted of increased actin fluorescence of partially disintegrated MF arrays in cells of the DTZ. These tissue- and development-specific alterations to the cytoskeleton were preceded by and/or coincided with Al-induced depolarization of the plasma membrane and with callose formation, particularly in the outer cortex cells of the DTZ. Longer Al supplies (> 6 h) led to progressive enhancements of lesions to the MT cytoskeleton in the epidermis and two to three outer cortex cell files. Our data show that the cytoskeleton in the cells of the DTZ is especially sensitive to Al, consistent with the recently proposed specific Al sensitivity of this unique, apical maize root zone.

AB:   Many reports have shown that plant growth and yield is superior on mixtures of NO(3)(-) and NH(4)(+) compared with provision of either N source alone. Despite its clear practical importance, the nature of this N-source synergism at the cellular level is poorly understood. In the present study we have used the technique of compartmental analysis by efflux and the radiotracer (13)N to measure cellular turnover kinetics, patterns of flux partitioning, and cytosolic pool sizes of both NO(3)(-) and NH(4)(+) in seedling roots of rice (Oryza sativa L. cv IR72), supplied simultaneously with the two N sources. We show that plasma membrane fluxes for NH(4)(+), cytosolic NH(4)(+) accumulation, and NH(4)(+) metabolism are enhanced by the presence of NO(3)(-), whereas NO(3)(-) fluxes, accumulation, and acquisition and N translocation to the shoot with dual N-source provision are substantially larger than when NO(3)(-) or NH(4)(+) is provided alone at identical N concentrations.

AB:   Barley (Hordeum vulgare L.) is a long-day plant whose flowering is enhanced when the photoperiod is supplemented with far-red light, and this promotion is mediated by phytochrome. A chemically mutagenized dwarf cultivar of barley was selected for early flowering time (barley maturity daylength response [BMDR]-1) and was made isogenic with the cultivar Shabet (BMDR-8) by backcrossing. BMDR-1 was found to contain higher levels of both phytochrome A and phytochrome B in the dark on immunoblots with monoclonal antibodies from oat (Avena sativa L.) that are specific to different members of the phytochrome gene family. Phytochrome A was light labile in both BMDR-1 and BMDR-8, decreasing to very low levels after 4 d of growth in the light. Phytochrome B was light stable in BMDR-8, being equal in both light and darkness. However, phytochrome B became light labile in BMDR-1 and this destabilization of phytochrome B appeared to make BMDR-1 insensitive to photoperiod. In addition, both the mutant and the wild type lacked any significant promotion of flowering in response to a pulse of far-red light given at the end of day, and the end-of-day, far-red inhibition of tillering is normal in both, suggesting that phytochrome B is not involved with these responses in barley.

AB:   Embolism amd refilling of vessels was monitored directly by cryomicroscopy of field-grown corn (Zea mays L.) roots. To test the reliability of an earlier study showing embolism refilling in roots at negative leaf water potentials, embolisms were counted, and root water potentials (psi(root)) and osmotic potentials of exuded xylem sap from the same roots were measured by isopiestic psychrometry. All vessels were full at dawn (psi(root) -0.1 MPa). Embolisms were first seen in late metaxylem vessels at 8 AM. Embolized late metaxylem vessels peaked at 50% at 10 AM (psi(root) -0.1 MPa), fell to 44% by 12 PM (psi(root) -0.23 MPa), then dropped steadily to zero by early evening (psi(root) -0.28 MPa). Transpiration was highest (8.5 microgram cm(-2) s(-1) between 12 and 2 PM when the percentage of vessels embolized was falling. Embolized vessels were refilled by liquid moving through their lateral walls. Xylem sap was very low in solutes. The mechanism of vessel refilling, when psi(root) is negative, requires further investigation. Daily embolism and refilling in roots of well-watered plants is a normal occurrence and may be a component of an important hydraulic signaling mechanism between roots and shoots.

AB:   A transference chamber was developed to measure the osmotic water permeability coefficient (P(os)) in protoplasts 40 to 120 micrometer in diameter. The protoplast was held by a micropipette and submitted to a steep osmotic gradient created in the transference chamber. P(os) was served from the changes in protoplast dimensions, as measured using a light microscope. Permeabilities were in the range 1 to 1000 micrometer s(-1) for the various types of protoplasts tested. The precision for P(os) was <(or)= 40%, and within this limit, no asymmetry in the water fluxes was observed. Measurements on protoplasts isolated from 2- to 5-d-old roots revealed a dramatic increase in P(os) during root development. A shift in P(os) from 10 to 500 micrometer s(-1) occurred within less than 48 h. This phenomenon was found in maize (zea mays), wheat (Triticum aestivum), and rape (Brassica napus) roots. These results show that early developmental processes modify water-transport properties of the plasma membrane, and that the transference chamber is adapted to the study of water-transport mechanisms in native membranes.

AB:   The single gene encoding limit dextrinase (pullulan 6-glucanohydrolase; EC 3.2.1.41) in barley (Hordeum vulgare) has 26 introns that range in size from 93 to 822 base pairs. The mature polypeptide encoded by the gene has 884 amino acid residues and a calculated molecular mass of 97,417 D. Limit dextrinase mRNA is abundant in gibberellic acid-treated aleurone layers and in germinated grain. Gibberellic acid response elements were found in the promoter region of the gene. These observations suggest that the enzyme participates in starch hydrolysis during endosperm mobilization in germinated grain. The mRNA encoding the enzyme is present at lower levels in the developing endosperm of immature grain, a location consistent with a role for limit dextrinase in starch synthesis. Enzyme activity was also detected in developing grain. The limit dextrinase has a presequence typical of transit peptides that target nascent polypeptides to amyloplasts, but this would not be expected to direct secretion of the mature enzyme from aleurone cells in germinated grain. It remains to be discovered how the enzyme is released from the aleurone and whether another enzyme, possibly of the isoamylase group, might be equally important for starch hydrolysis in germinated grain.

AB:   Accessions of annual Phalaris species in germplasm collections lack adequate genetic characterization for utilization. The objective of this study was to assess the level of isozyme variability of five annual Phalaris species, including 49 annual canarygrass (P. canariensis L.; 2n = 2x = 12), 24 P. brachystachys Link. (2n = 2x = 12), 48 P. minor Retz. (2n = 4x = 28), 19 P. paradoxa L. (2n = 2x = 14), and 3 P. angusta Nees cx Tris (2n = 2x = 14) accessions from North American germplasm collections. Eight enzymes were used to detect polymorphism within and among accessions by scoring the presence or absence of 62 bands. Polymorphism was detected in 6 of 19 bands in P. canariensis, 12 of 22 bands in P. brachystachys, 34 of 40 bands in P. minor, 19 of 29 bands in P. paradoxa, and 6 of 21 bands in P. angusta. Polymorphism was detected in 23 accessions (47%) of P. canariensis, 15 accessions (63%) of P. brachystachys, 35 accessions (73%) of P. minor, four accessions (19%) of P. paradoxa and three accessions of P. angusta (100%). Within-accession polymorphic indices ranged from 0 to 0.03 in P. canariensis, 0 to 0.02 in P. brachystachys, 0 to 0.06 in P. minor, 0 to 0.04 in P. paradoxa. and 0.01 to 0.04 in P. angusta. Jaccard's similarity coefficients ranged from 0.83 to 1.0 in P. canariensis, 0.78 to 1.0 in P. brachystachys, 0.47 to 1.0 in P. minor, 0.44 to 1.0 in P. paradoxa, and 0.81 to 0.86 in P. angusta. Little isozyme variation existed either within or among accessions of the four diploid species. Phalaris minor, an autotetraploid, possessed greater variation among accessions rather than within accessions. In summary, limited variation was detected by means of isozymes in these.

AB:   Plant genetic resources conservation is a challenge based on the need to balance acquisition priorities with the constrained level of financial support that is dedicated to long-term maintenance of collections. As such, understanding how variation is partitioned among accessions is essential for effective management. It is generally recognized that most large collections exhibit varying levels of genetic redundancy. To address this issue, all of the sorghum [Sorghum bicolor (L.) Moench] accessions identified as 'Orange' presently maintained by the U.S. National Plant Germplasm System (NPGS) were assayed with 15 simple sequence repeat (SSR) markers. Genotyping was performed with fluorescent primers with five primer sets in each of three multiplex polymerase chain reactions (PCRs) and automated allele sizing. A total of 96 individuals were analyzed, five plants from each of 19 Orange accessions and one individual from an elite inbred line, 'RTx430'. The SSR markers provided substantial genetic resolution among the Orange entries. Average heterozygosity estimates were low, and phenetic analyses (neighbor-joining dendograms) were generally consistent with known historical relationships among accessions. Most accessions were genetically distinct, but two redundant groups (involving a total of five entries) were found among the 19 Orange accessions evaluated. The molecular variance analysis (AMOVA) showed that 90% of the total genetic variation was partitioned among accessions, while one-tenth of the variation resulted from genetic differences between individual plants within accessions. The variance analysis also indicated that it should be possible to reduce the.
       number of Orange accessions held by NPGS by almost half without seriously jeopardizing the overall amount of genetic variation contained in these holdings. This study demonstrated that a limited number of SSR markers can be used in a cost-efficient manner to rapidly assess variation in accessions of Orange sorghum.

AB:   Cultivated hexaploid oat (Avena sativa L. and A. byzantina C. Koch) is classified as a secondary crop, i.e., derived from weeds of the primary cereal domesticates of the Near East. Avena sterilis L., the oldest hexaploid oat, is the putative progenitor of all other cultivated and wild hexaploid oat species. The objectives of this research were to gain insight into the origin of cultivated hexaploid oat by means of random amplified polymorphic DNA (RAPD) marker variation and the distribution of the 7C-17 intergenomic chromosomal translocation in cultivated and progenitor accessions. Cluster analyses based on 248 polymorphic RAPD markers found close association between several A. sterilis accessions from the Iran-Iraq-Turkey region and cultivated accessions. Genotypes within this group of cultivated and progenitor accessions were divided into those with the 7C-17 translocation (A. sativa and A. sterilis) and those without the translocation (A. byzantina and A. sterilis). The results suggested that all cultivated hexaploids are derived from progenitor germplasm from Southwest Asia, present-day Iran, Iraq, and Turkey. At least two paths of domestication occurred: one from A. sterilis with the translocation to A. sativa and one from A. sterilis without the translocation to A. byzantina.

AB:   Kernel morphology and texture influence the value of wheat (Triticum aestivum L.). The objectives of this study were to determine associations between kernel traits and molecular markers and to identify quantitative trait loci (QTLs) affecting kernel traits in a soft x hard white wheat cross. Seventy eight F(2.5)-derived recombinant inbred lines (RILs) from a cross between the soft white wheat NY6432-18 (NY18) and the hard white wheat 'Clark's Cream' (CC) were developed by single seed descent. Kernel texture was measured by near infrared reflectance (NIR) on RIL grain samples from six environments. Digital image analysis (DIA) was used to measure kernel length, width, area, perimeter on grain samples from four environments. Test weight and thousand kernel weight (TKW) were also determined. Shape factor and density factor were calculated. The map for this population consisted of 313 molecular markers in 47 linkage groups located on all wheat homoeologous chromosome groups. Linkage groups that mapped to wheat homoeologous group 2 chromosomes were highly skewed towards NY18 alleles. Genotype effects and genotype x environment interactions were highly significant for most traits. QTLs for kernel width and kernel length also influenced kernel area and TKW, but did not influence each other. The pinB marker at the puroindoline B locus on chromosome 5DS explained over 60% of the phenotypic variation for kernel texture. QTLs for kernel traits were located on chromosomes 1A, 2B, 2D, 3B, 7A, and 7B.

AB:   The ovicidal response in rice (Oryza sativa L.) to whitebacked planthopper (WBPH), Sogatella furcifera Horvath, is characterized by the formation of watery lesions which result in the death of WBPH eggs. To determine the genetic mechanism of this ovicidal response, a set of 71 rice recombinant inbred (RI) lines (F(8), F(9), and F(10)) derived from a cross of japonica cultivar Asominori and indica cultivar IR24, the two parents, and the F(1) were phenotyped for percentage of watery lesions (PWL) and WBPH egg mortality (EM). PWL and EM showed significant positive correlations (P < 0.001) and transgressive segregation was observed for both traits. A total of 10 quantitative trait loci (QTLs) for ovicidal response were detected with 292 RFLP markers in the F(6) and F(7) populations by composite interval mapping (LOD > or = to 1.5). Four of 10 QTLs coincided for PWL and EM and each three QTLs were only detected for PWL and EM. The QTL on chromosome 6 (R1954-L688) was most significantly associated with the ovicidal response and accounted for 69.9% of phenotypic variance for PWL (F(8)) and 46.0% of phenotypic variance for EM (F(8)). Positive alleles for ovicidal response came from Asominori on chromosomes 1, 3, 6S (short arm), 8, and 12 and from IR24 on chromosomes 2, 6L (long arm), and 10. QTL accumulation from both parents was the genetic basis of the transgressive segregation in the RI population. No epistatic interaction was detected. The Asominori allele on the chromosome 6S QTL was essential to the ovicidal response, and R1954 was found to be a target marker for marker assisted selection.

AB:   High Plains disease has the potential to cause significant yield loss in susceptible corn (Zea mays L.) and wheat (Triticum aestivum L.) genotypes, especially in the central and western USA. The primary causal agent, High Plains virus (HPV), is vectored by wheat curl mite (WCM; Aceria tossichella Keifer), which is also the vector of wheat streak mosaic virus (WSMV). In general, the two diseases occur together as a mixed infection in the field. The objective of this research was to characterize the inheritance of HPV and WSMV resistance using B73 (resistant to HPV and WSMV) X Mol7 (moderately susceptible to HPV and WSMV) recombinant inbred lines. A population of 129 recombinant inbred lines scored for 167 molecular markers was used to evaluate resistance to WSMV and to a mixed infection of WSMV and HPV. Loci conferring resistance to systemic movement of WSMV in plants mapped to chromosomes 3, 6, and 10, consistent with the map position of wsm2, wsm1, and wsm3, respectively. Major genes for resistance to systemic spread of HPV in doubly infected plants mapped to chromosomes 3 and 6, coincident or tightly linked with the WSMV resistance loci. Analysis of doubly infected plants revealed that chromosome 6 had a major effect on HPV resistance, consistent with our previous analysis of B73 x W64A and B73 x Wf9 populations. Quantitative trait loci (QTL) affecting resistance to localized symptom development mapped to chromosomes 4 (umc66), 5 (bnl5.40), and 6 (umc85), and accounted for 24% of the phenotypic variation. Localized symptoms may reflect the amount of mite feeding or the extent of virus spread at the point of infection. Identification of cosegregating markers may.
       facilitate selection for HPV and WSMV resistance in corn breeding programs.

AB:   Soluble acidity has been used as one of major indexes to reflect the changes of rice (Oryza sativa L.) grain quality during storage. The acidity is in general visually examined by pH dye indicators or directly measured by a pH meter. By combining the characteristics of pH dye indicator, 96-well microplate, and microplate reader, we have developed a procedure capable of effectively measuring the pH value of rice grains at a single-grain level. First, from a pH-dye system prepared with methyl red and bromothymol blue, we scanned the spectral response to pH and determined that a wavelength of 630 nm showed the maximum response to pH changes with storage age of rice grains. By means of a 96-well microplate and plate reader, a pH standard curve was then constructed with a series of pH standard buffers and absorbance at 630 nm. The pH value of a single grain in a microplate well can be measured by incubating the grain with dye solution and reading absorbance. The proposed procedure offers an efficient means of measuring the change of soluble acidity in rice grains during storage on an individual-grain basis. The method may also rapidly detect the uniformity or blending status of fresh/old grains in a sample.

AB:   Seashore paspalum (Paspalum vaginatum Swartz) displays wide intraspecific diversity and exhibits tolerance to numerous abiotic stresses. In addition, comparatively low fertility requirements and high quality growth characteristics of many ecotypes render this grass a prospective candidate for use on golf courses, athletic fields, and landscaped areas in warm climates worldwide. The objectives of this research were to evaluate the relative growth, quality, and wear tolerance of seashore paspalum and bermudagrass. This research was conducted in two consecutive field trials during 1997 under wear and non-wear conditions on seven seashore paspalum ecotypes and three hybrid bermudagrass (Cynodon dactylon L. x C. (transvaalenvis Burtt-Davy) cultivars established on a native Appling sandy clay loam (clayey, kaolinitic, thermic typic Kanhapludult) at the University of Georgia Experiment Station at Griffin, GA. We found that two paspalum ecotypes, Temple 1 and SIPV-2 , ranked as high or higher than 'tifway' and 'Tifsport' for visual quality, shoot density, shoot growth, and amount of verdure tissue under non-wear conditions. In addition, these two paspalum ecotypes showed the most favorable spectral reflectance data responses, indicating greatest utilization of intercepted light, and also showed rates of recovery from wear which were equal to or greater than those of the bermudagrass entries. Vaspalum ecotypes Temple 1 and SIPV-2 appear to be suitable for use in areas where a high quality, traffic-tolerant turfgrass is required. Paspalum ecotypes with lower shoot densities were less wear tolerant.

AB:   Creeping bentgrass (Agrostis palustris Huds.) turf exposed to shade during morning hours may decline more readily than similar turf exposed to afternoon shade. This study compared the quality and physiological responses of creeping bentgrass turf exposed to morning shade with turf exposed to afternoon shade and evaluated responses of the same species exposed to varying shade densities during the same period. Semipermanent shade structures were placed on a creeping bentgrass range maintained at a 6.4-mm height. Structures provided 6 h of morning shade or 6 h of afternoon shade during the summer solstice. Each structure was covered with either 80 or 100% shade cloth and replicated three times. Control treatments of full sun and perpetual shade were also included. Treated turf was evaluated monthly for color, density, root mass, pigment concentrations, and total nonstructural carbohydrates (TNC). Regardless of response tested, no significant variation was found between plots receiving morning shade and afternoon shade or between plots in 80 and 100% shade. Canopy temperature, in comparison with air temperature, was 7% greater in morning shade than in afternoon shade. but the relationship between canopy temperatures in full sun and shade did not change during the day. Perpetual shade caused a 38% decrease in color and a 33% decline in density but treatments receiving 6 h of shade did not vary from the full sun treatment. Concentrations of chlorophyll a (46%) and b (50%), neoxanthin (31%), violaxanthin (44%), and lutein (34%) declined in perpetual shade compared with full sun. Violaxanthin concentration was influenced by photosynthetic photon flux, suggesting its potential.

AB:   Simple sequence repeats (SSRs) have proven to be useful genetic markers in a wide variety of plants, but have yet to be widely applied to turfgrasses. Here we describe a study of SSRs in perennial ryegrass (Lolium perenne L.). A library of perennial ryegrass genomic DNA was screened with (GA)(n) and (GT)(n) probes, and SSR-containing clones were isolated and sequenced. On the basis of this screen, we estimated that there are roughly 5800 (GA)(n) and (GT)(n) SSRs in the haploid perennial ryegrass genome. Polymerase chain reaction (PCR) primers were designed to amplify the isolated SSRs, and six polymorphic SSRs were identified. Polymorphism in the these six SSRs was sufficient to discriminate among 18 individuals representing 11 perennial ryegrass clones and seven other Lolium species. Half-sibs could be distinguished with data from as few as three SSRs. The SSR genotype data was also used to infer generic relationships among the individuals of our sample. The relationships were in broad agreement with those established by previous analyses, suggesting that SSR data will be useful for exploring relationships among perennial ryegrass cultivars. In total, this study indicates that SSRs are sufficiently abundant and sufficiently polymorphic to be useful genetic markers in perennial ryegrass.

AB:   Anthracnose basal rot (ABR), caused by Colletotrichum graminicola (Ces.) Wils., is a destructive disease of annual bluegrass (Poa annua L.) and creeping bentgrass (Agrostis palustris Huds.) golf course putting greens in North America and western Europe. Typically, only one of these turfgrass species is affected by ABR when both are present in putting greens. The objectives of this study were to determine if isolates of C. graminicola from annual bluegrass and creeping bentgrass are host specific and if differences in pathogenicity, morphology, and randomly amplified polymorphic DNA (RAPD) marker profiles occur among isolates from annual bluegrass, creeping bentgrass, and corn (Zea mays L.). One isolate of C. sublineolum P. Henn. apud Kabat & Bub. from sorghum [Sorghum bicolor (L.) Moench] was included for comparison in morphology and RAPD marker studies. Pathogenicity studies using C. graminicola isolates were conducted in growth chambers on annual bluegrass and creeping bentgrass. Although several isolates were more virulent on the host species from which they were isolated, strict host specificity was not observed. No consistent differences in conidia length were found between annual bluegrass isolates and those from creeping bentgrass. However, differences in conidia length were found between corn isolates and isolates from turfgrasses and sorghum. Cluster analyses of RAPD markers showed that isolates from annual bluegrass and creeping bentgrass separated into two distinct groups. Analysis of molecular variance (AMOVA) revealed that significant genetic differences (P = 0.001) exist between isolates obtained from annual blue-grass and isolates from creeping bentgrass.

AB:   Weed invasion in alfala (Medicago sativa L.) may be reduced by seeding with a perennial forage grass. Our objectives were to determine if any of four perennial grasses influenced weed invasion when seeded with alfalfa, with and without an oat companion, and if this reduction was consistent among harvests and throughout the duration of the stand. Alfalfa was seeded alone and in binary mixtures with smooth bromegrass (Bromus inermis Leysser), orchardgrass (Dactylis glomerata L.), timothy (Phleum pratense L.), or Kentucky bluegrass (Poa pratensis L.). All forages were seeded with and without an oat (Avena sativa L.) companion crop in May of 1993 and 1994. Seeding grass with alfalfa occasionally reduced weed yield in the first 2 yr of the stand. Weed density was not influenced by the perennial grasses in the seeding year. In the third year, mixtures containing orchardgrass or Kentucky bluegrass reduced weed yields by 20 to 130 kg ha(-1) in three of four harvests and dandelion (Taraxacum officinale Wigg.) density up to 5.4 plants m(2) (71%). Bromegrass and timothy did not persist with four annual harvests. Seeding the mixtures with an oat companion reduced weed and perennial grass yield in the seeding year and perennial grass yield the following year. As a result, dandelion density in the third year was 2.6 plants m(2) (70%) greater in mixtures established with oat than without oat. Including perennial forage grasses can be effective at reducing weed invasion by the third year of the stand if grass is maintained as a major component of the forage.

AB:   Reduced forage production, grain yield, and visual N deficiency symptoms in no-till winter wheat (Triticum aestivum L.) prompted this study. Our objectives were to determine the effect of urea placement and two nitrification inhibitors--nitrapyrin [2-chloro-6 (trichloromethyl) pyridine] (NP) and dicyandiamide (DCD)--on aerial dry matter and N accumulation. A 4-yr field study was conducted on a Renfrow silt loam soil (fine-silty, mixed, thermic Udertic Paleustoll) silt loam near El Reno, OK. The seven treatments included urea fertilizer (60 kg N ha(-1)) with and without the two inhibitors, surface broadcast or banded 3 to 4 cm below the seed row, and an unfertilized control. Aerial dry matter accumulation during autumn was higher for banded urea plus DCD (22%) and broadcast urea plus DCD (25%), than for broadcast urea without an inhibitor. Whole plant N content during autumn also was higher for banded urea plus DCD (28%) than for broadcast urea without an inhibitor. Neither inhibitor nor placement affected total dry matter accumulation measured at tillering, but differences were noted at spike emergence, grainfill, and final harvest. At spike emergence in 1991, when climatic conditions were favorable for early season wheat growth, N content was greater for broadcast urea plus nitrapyrin than for broadcast urea or banded urea without inhibitor. At final harvest, both DCD treatments exhibited greater N content than all other N treatments. In 1993, when climatic conditions were favorable for leaching, DCD was effective in slowing nitrification and increasing N uptake, regardless of fertilizer placement. Our results suggest that fall application of DCD with urea can potentially increase autumn forage.

AB:   Development of maize (Zea mays L.) types that produce leaf area quickly and mature rapidly may increase maize yields in mid- to short-season areas. The leafy (Lfy1) and reduced-stature (rd1) traits each contribute to this objective; however, these two traits have not previously been combined. Our objective was to determine the effect of these traits, alone or in combination, on morphology, reproductive development, and yield of maize hybrids. A field experiment including 14 hybrids [two non-leafy reduced-stature (NLRS), four leafy reduced-stature (LRS), eight leafy normal-stature (LNS)], and three commercial hybrid checks [non-leafy normal-stature (NLNS)] was conducted in 1992 and 1993. The following variables were recorded for each hybrid: plant height, internode length, ear height, above-ear leaf number, above-ear leaf area, corn heat units from planting to tasseling, corn heat units from planting to silking, days from tasseling to silking, grain yield (Mg ha-1), grain moisture content, husk dry weight, husk moisture content, cob dry weight, cob moisture content, kernel number per row, maximum ear circumference, and ear length. The normal stature hybrids were the tallest plants, with higher ear placement than reduced stature hybrids. The leafy trait was associated with shorter internodes, increased leaf number, and greater above-ear leaf area. The reduced stature hybrids required fewer corn heat units to reach anthesis than the normal stature hybrids. The reduced stature hybrids had the lowest grain moisture (210-270 g kg-1), husk moisture, and cob moisture contents at the time of harvesting. The LNS hybrids matured late and had grain moisture contents of 350 to 400 g kg-1 at harvest. In.
       general grain yield, husk dry weight, cob dry weight, kernel number per row, ear length, and maximum ear circumference were higher for the normal stature hybrids than for the reduced stature hybrids. The earlier anthesis and lower grain, husk, and cob moisture contents indicated potential for successful grain production and harvest of leafy reduced-stature hybrids in shorter growing season areas.

AB:   Although primordium initiation in wheat (Triticum aestivum L.) has been extensively researched, a complete description of the growth dynamics of the apex at elevated CO2 concentrations is lacking. This study determined the rates of main stem and tiller apical elongation and widening in plants grown under two levels of CO2 concentration. Spring wheat was grown at the University of Arizona's Maricopa Agricultural Center at elevated (550 micromol mol-1) or ambient (370 micromol mol-1) CO2 concentrations. Individual plant samples were collected at different developmental stages and dissected. After dissection, the lengths and widths of the apices of the main stem (MS), coleoptile tiller (T0), primary tillers (T1, T2, and T3), and secondary tillers (T00, T01, T02, T10, T11, and T12) were measured with a stage micrometer. Apex dimensions were fitted to an exponential model. Elevated CO2 increased the apex lengths of T2 at the double ridge stage, and of T3 and T10 at the double ridge and the terminal spikelet stages, and the apex widths of T2 at double ridge stage, and of T2, T3, T10, and T11 at the flag leaf appearance stage. Combining these results with a parallel study, the longer apices did not have more spikelet primordia, but wider apices had more floret primordia. Elevated CO2 changed apex elongation or widening patterns within a plant by enhancing elongation or widening rates of the MS, and later-formed tillers. Earlier-formed tillers were less responsive to elevated CO2 levels. This information will be used in modeling wheat apical development and grain production in the elevated atmospheric CO2 environments of the future.

AB:   Knowledge of heterotic patterns is essential in hybrid maize (Zea mays L.) breeding programs. Second cycle inbreds of maize were developed from crosses between three historical European inbreds (EP1, F2, and F7) and American or European germplasm. The objective of this study was to find out if the second cycle inbreds derived from EP1, F2, and F7 preserved the European flint heterotic group. Crosses of first and second cycle inbreds with four testers (W64A, A619, A632, and W117) were evaluated in northwestern Spain. Second cycle inbreds from EP1 or F2 x European germplasm had the highest yield and early vigor in crosses to the testers, probably because flint x dent heterosis was preserved. The U.S. germplasm used to develop second cycle inbreds from EP1 and F2 included germplasm from the open-pollinated variety Minnesota No. 13. The use of Minnesota No. 13 germplasm to develop second cycle inbreds from crosses to European flint should be avoided because almost all the early U.S. Corn Belt dent inbreds introduced into Europe are related to Minnesota No. 13. 'Lancaster' germplasm was suitable to improve the yield of F7, but this material lacked early vigor. Lancaster-related second cycle inbreds performed better for yield than the 'Reid Yellow Dent' because two testers were of Reid origin. The highest early vigor was obtained for second cycle inbreds from F7 x European inbreds. European flint germplasm is appropriate for improving European inbreds in crosses to U.S. germplasm, whereas the U.S. germplasm may be used to improve a specific cross.

AB:   Oat (Avena sativa L.) is a potentially economically viable source of lipase, an enzyme used in foods, chemicals, and pharmaceuticals, which occurs on the surface of oat caryopses (groats). The objectives of this study were to: (i) estimate the broad-sense heritability of the lipase activity of oat caryopses, (ii) determine the genetic and phenotypic correlations between lipase activity and other important agronomic traits, and (iii) test whether five cycles of recurrent selection for test weight caused a correlated response in lipase activity. Entries included 10 check cultivars, 95 randomly chosen S(0)-derived lines from the initial cycle (C0), and 19 S(0)-derived lines from C5 of a population developed by randomly mating oat cultivars and lines adapted to the midwestern USA. Entries were grown at three Iowa locations in 1996 and 1997. Broad-sense heritability estimates for lipase activity were 0.22 on a sample basis in the population, and 0.63 on a line-mean basis, Lipase activity had positive genetic correlations with total biomass (r = 0.31), heading date (r = 0.53), and plant height (r = 0.58), positive phenotypic correlations with heading date (r = 0.18) and plant height (r = 0.26), and negative phenotypic correlations with biomass (r = -0.13), test weight (r = -0.30), weight of 50 seeds (r = -0.18), weight of 50 groats (r = -0.40), and groat percentage (r = -034). The C0 and C5 populations did not differ for mean lipase activity, indicating that selection for increased test weight did not affect lipase activity. We suggest that selection for cultivars with higher lipase activity and acceptable grain quality is possible.

AB:   The availability of recessive genes for early flowering-day length insensitivity offers an opportunity to synchronize the flowering of late-flowering or day length-sensitive parents with that of early-flowering parents without necessarily affecting the flowering of their hybrids, provided that the earlier parent does not carry the same recessive allele. This study evaluated the hypothesis that incorporating the recessive e(1), allele for early flowering-day length insensitivity into a late-flowering, photoperiod-sensitive pollinator in pearl millet [Pennisetum glaucum (L.) R. Br.] would synchronize its flowering and improve seed production with earlier-flowering female parents, without affecting the time to flowering or the performance of the resulting hybrids. An e(1)/e(1) isoline of the late-flowering pollinator ICMP 85410, produced by six backcrosses, flowered 16 d earlier under natural day lengths at Patancheru, India, (17 degrees N) and 19 d earlier under extended day lengths (equivalent to 29 degrees N) than its near isogenic E(1)/E(1) counter-part. As a consequence, it successfully produced hybrid seed when sown simultaneously with early, male-sterile line 843A, whereas the late isoline failed under the same conditions. The E(1)/e(1) versions of eight near-isogenic hybrids (on a range of eight E(1)/E(1), male-steriles) flowered an average of 3 d earlier than their E(1)/E(1) counterparts in 2 yr of tests under both natural and extended day length conditions at the same location. This earlier flowering had small effects on hybrid yield components, consistent with known effects of earliness in the crop, but did not affect grain yield. The results indicate that the e(1) allele is.
       a powerful tool for exploiting heterosis between early- and late-flowering parents in pearl millet, which is otherwise difficult to realize without complicated seed production practices.

AB:   Species cytoplasm specific (scs) genes on chromosome 1A (1A(scs)) derived from Triticum timopheevii Zhuk. and chromosome 1D (1D(scs)) derived from common wheat improve compatibility between the durum wheat (T. turgidum L. var. durum) nucleus and Aegilops longissima S.& M. (lo) cytoplasm. The (lo) scs durum lines thus produced are male sterile and when crossed with durum produce viable plump seeds carrying scs and inviable shriveled seeds without scs. Objectives of the present study were to determine centromere-scs linkage distances and viability and transmission of female gametes carrying one or both scs genes. The (lo) scs durum heterozygous for 1A/1A(scs) was crossed with the Langdon (LDN) durum disomic substitution line 1D(scs)(1A) in which the 1A chromosome pair is substituted by a 1D(scs) pair. Two types of 1A + 1D double monosomic F(1)s were recovered, (lo) durum l3" + 1'1A(scs) + 1'1D(scs), and (lo) durum 13" + 1'1A + 1'1D(scs), which were confirmed in progeny tests with normal durum. For centromere mapping, these lines were crossed with LDN double ditelosomic 1A (LDN dDt 1A; 2n = 30; 13" + t"1AS + t"1AL) and progeny examined for meiotic chromosome constitution. No telocentric t1AL(scs) arising from recombination with 1A(scs) was detected, indicating that scs is tightly linked to the centromere on chromosome 1A. To determine the transmission of female gametes carrying one or both scs genes, (lo) durum 13" + 1'1A + 1'1D(scs) was crossed with LDN dDt 1A and control durum. The functional female gametes carried one or both scs genes. Crosses of (lo) durum 13" 1'1A + 1'lD(scs) to LDN dDt 1A produced several plants with a T1AL.1DL translocation chromosome. The formation of.
       this chromosome was coupled with strong selection for the scs gene on 1DL.

AB:   Montana-2 (MT-2; x Agrotriticum intermediodurum Khizhnyak) is a variable perennial F(5:15) line derived from hybridization between durum wheat (Triticum turgidum L. var. durum, AABB) and Thinopyrum intermedium (Host) Barkw. & D.R. Dewey (StStEEEE). OK-906 is a uniform annual line derived from hybridization between hexaploid wheat (Triticum aestivum L., AABBDD) and an unknown Thinopyrum sp. followed by backcrossing to wheat and several generations of selfing and selection. We wished to characterize perennial (Thinopyrum) and annual (Triticum) chromosome content of MT-2 and OK-906 to determine how chromosome content corresponds to perenniality. When DNA of genomes ABD (T. aestivum) + E(b) [Thinopyrum bessarabicum (Savul & Rayss) Love] was used as the block and DNA of the genome St {Pseudoroegneria stipifolia (Czern. ex Nevski) A. Love] was used as the probe, the average chromosome content among 15 MT-2 lines was 26.2 wheat + 9.4 St + 18.8 + 1.5 St/E translocation = 55.9 chromosomes (8x). Variation for genomic content was found within as well as among MT-2 lines, indicating that instability remains in the material. OK-906 exhibited about 40 wheat + 6 St + 8 E + 2 St/E translocation = 56 chromosomes (8x), but some aneuploidy was present. Its chromosome content is similar to 'Agrotana', another wheat x Thinopyrum annual. Perenniality in MT-2 may relate to its higher perennial chromosome dosage (about 30 of about 56 chromosomes) than OK-906 or Agrotana (16 of 56 chromosomes). Alternatively, specific genes or chromosome segments may confer perenniality. Development of stable breeding populations from MT-2 is improbable because of its variable chromosome constitution. However, individual lines could be.
       useful for forage if they could be stabilized with improved seed yield.

AB:   It is not known whether selection for improved tolerance to a specific abiotic stress leads to correlated changes in performance under other stresses. Drought and N deficiency are important constraints to production in the tropics. We examined the effect of selection for drought tolerance on performance of tropical maize (Zea mays L.) under a range of N levels. Original and advanced selections of four populations, improved for tolerance to midseason drought for two to eight recurrent selection cycles each, were evaluated in two experiments under severe N stress, one experiment under medium N stress, and two well-fertilized experiments. Nitrogen accumulated in the aboveground biomass at maturity averaged 52, 63, 105, 151, and 163 kg N ha(-1) in the five experiments, and grain yields of 3.0, 2.9, 5.2, 6.0, and 6.5 Mg ha(-1) were obtained. Selection for tolerance to midseason drought stress increased grain yields by an average of 86 kg ha(-1) yr(-1) with nonsignificantly larger gains under severe N stress (100 kg ha(-1) yr(-1)). Drought-tolerant selections had increased biomass and N accumulation at maturity, the changes being largest under severe N stress. Additionally, drought-tolerant selection cycles were associated with delayed leaf senescence and an increased or unchanged N harvest index, indicating that leaf N was used more efficiently for grain production. Selection for tolerance to midseason drought stress appears to increase grain yield across a range of N stress levels and may lead to morphological and physiological changes that are of particular advantage under N stress.

AB:   Previous studies with chromosome substitution lines between hard red winter wheat (Triticum aestivum L.) cultivars Cheyenne (CNN) and Wichita (WI) identified genes on chromosome 3A of WI which affect grain yield, yield components, grain volume weight, plant height, and anthesis date. This study was conducted to determine if the trait variation caused by chromosome 3A could be explained by major or minor gene segregation and if these genes are pleiotropic, linked, or independent on the chromosome. A population of recombinant inbred chromosome lines for chromosome 3A (RICLs-3A), developed between CNN and a chromosome substitution line CNN (WI3A), was evaluated in multi-location field trials in 3 yr. Our results indicate significant differences (P < or = 0.05) between parental lines and among RICLs for grain yield, 1000-kernel weight, plant height, and anthesis date, but not for kernel number per spike, spike number per square meter, and grain volume weight. A 1:1 genetic ratio for anthesis date suggested the presence of a single segregating locus controlling the trait. None of the other agronomic traits could be separated into unequivocal groups and hence, major genes were not detected. This indicates that the traits were controlled either by several genes or few genes with enough environmental influence, or both, to obscure their effects. Significant correlations and possible crossover products between anthesis date, plant height, and 1000-kernel weight suggest that these traits were controlled either by linked gene(s) or by pleiotropic genes with additional genes affecting one of the traits.

AB:   Multiplicative statistical models such as the additive main effects and multiplicative interaction model (AMMI), the genotypes regression model (GREG), the sites regression model (SREG), the completely multiplicative model (COMM), and the shifted multiplicative model (SHMM) are useful for studying patterns of yield response across sites and estimating realized cultivar responses in specific environments. Traditionally the series of multiplicative terms is truncated at some point beyond which further terms are believed to have little statistical significance or predictive value. Shrinkage estimators have been advocated as a model fitting method superior to model truncation. In this study, by data splitting and cross validation, we evaluated the predictive accuracy of (i) truncated multiplicative models, (ii) shrinkage estimators of multiplicative models, (iii) Best Linear Unbiased Predictors (BLUP) of the cell means based on a two-way random effects model with interaction, and (iv) empirical cell means in one wheat [durum (Triticum turgidum L. var. durum) and bread (Triticum aestivum L.)] and four maize (Zea mays L.) cultivar trials, with and without adjustment for replicate differences within environments. Shrinkage estimates of multiplicative models were at least as good as the better choice of truncated models fitted by least squares or BLUPs. Shrinkage estimation yields potentially better estimates of cultivar performance than do truncated multiplicative models and eliminates the need for cross validation or tests of hypotheses as criteria for determining the number of multiplicative terms to be retained. If random cross validation is used to choose a truncated.
       model, data should be adjusted for replicate differences within environments.

AB:   Several putative hybrids between Elymus elymoides (Rafin.) Sweezey and Leymus salinus (M.E. Jones) A. Love subsp. salmonis (C. Hitchc.) Atkins were found growing on the west side of the Great Salt Lake, near Lakeside, UT in 1995. Naturally occurring hybrids between these two species have not been documented previously. Cytological, morphological, and chloroplast DNA analysis of the hybrids and parents confirmed the hypothesis that these plants were hybrids of the two species. Elymus elymoides and L. salinus subsp. salmonis were the only Triticeae species growing in the area that could have contributed to the intermediate morphological features expressed in the hybrids. Leymus salinus subsp. salmonis (NsNsXmXm; 2n = 4x = 28) and E. elymoides (StStHH; 2n = 4x = 28) are allotetraploids that regularly formed 14 bivalents at metaphase I (MI). The hybrids between the two species are also tetraploids and averaged 22.1 univalents and 2.86 bivalent associations per cell at MI. Chromosome pairing in the hybrids suggests essentially no homology between the chromosomes from the two parents; thus the genomic formula for the hybrid can be written as StHNsXm. The hybrids were morphologically intermediate between the suspected parent species, but they resembled L. salinus subsp. salmonis more closely than E. elymoides. Analysis of chloroplast DNA in the hybrid and its putative parents, demonstrates cytoplasmic DNA identical to E. elymoides, suggesting that E. elymoides was the maternal parent. Complete sterility and reduction in chromosome pairing in the natural hybrids between E. elymoides and L. salinus subsp. salmonis suggest that the potential for genetic exchange between the two.
       species is limited or lacking. Due to hybrid sterility, the natural hybrid will have little impact on the native vegetation of the western deserts of Utah and, without restored fertility, has no potential as a restoration grass on semiarid range sites.

AB:   Partial least squares (PLS) and factorial regression (FR) are statistical models that incorporate external environmental and/or cultivar variables for studying and interpreting genotype x environment interaction (GEI). The Additive Main effect and Multiplicative Interaction (AMMI) model uses only the phenotypic response variable of interest; however, if information on external environmental (or genotypic) variables is available, this can be regressed on the environmental (or genotypic) scores estimated from AMMI and superimposed on the AMMI biplot. The objectives of this study with two wheat [Triticum turgidum (L) var. durum] field trials were (i) to compare the results of PLS, FR, and ANIMI on the basis of external environmental (and cultivar) variables, (ii) to examine whether procedures based on PLS, FR, and AMMI identify the same or a different subset of cultivar and/or environmental covariables that influence GEI for grain yield, and (iii) to find multiple FR models that included environmental and cultivar covariables and their cross products that explain a large proportion of GEI with relatively few degrees of freedom. Results for the first trial showed that AMMI, PLS, and FR identified similar cultivar and environmental variables that explained a large proportion of the cultivar x year interaction. Results for the second wheat trial showed good correspondence between PLS and FR for 23 environmental covariables. For both trials, PLS and FR complement each other and the AMMI and PLS biplots offered similar interpretations of the GEI. The FR analysis can be used to confirm these results and to obtain even more parsimonious descriptions of the GEI.

AB:   Odors were collected from the headspace above fermented infusions of Bermuda grass, which commonly are used as attractants in traps for gravid mosquitoes. Coupled gas chromatography-electroantennogram detection (GC-EAD) was used to identify 9 compounds (phenol, p-cresol, 4-ethylphenol, indole, 3-methylindole, nonanal, 2-undecanone, 2-tridecanone, naphthalene) from odor extracts that elicited significant antennal responses from antennae of gravid female Culex quinquefasciatus Say and Culex tarsalis Coquillett mosquitoes. Several of these compounds at appropriate concentrations were weakly attractive to gravid female mosquitoes in laboratory bioassays and/or stimulated more oviposition than water controls. In addition, dimethyltrisulfide, a significant component of odor extract which did not elicit strong responses from female mosquito antennae in GC-EAD assay, also appeared to stimulate oviposition at 1 concentration. A reconstituted blend of the 10 compounds resulted in much stronger and more consistent responses than individual compounds. The blend was attractive to gravid Cx. quinquefasciatus and enhanced oviposition over a range of concentrations spanning 3 orders of magnitude. One concentration of the blend also attracted gravid Cx. tarsalis and enhanced oviposition. However, at the highest concentration tested, the blend was repellent to both species. Overall, these studies demonstrated that gravid mosquitoes are attracted to oviposition sites by blends of compounds rather than by individual chemicals, and that the concentration of compounds in the odor is a critical factor in determining whether responses are positive (attractive, stimulatory) or negative (repellent, deterrent).

AB:   Herbicides applied to control problem weed species can directly reduce the availability of non-target plant species and, indirectly, invertebrates important as food for birds. Therefore, the effects of an autumn herbicide application on the flora and invertebrate fauna were studied within the field headland of winter wheat (Triticum aestivum L.) crops over three years. Replicated plots were either treated with a herbicide or left untreated. Floral percentage cover and diversity were assessed in quadrats on two dates, and invertebrates sampled using a vacuum sampler on five dates, between May and July each year. A significantly greater floral cover (p < 0.001), species diversity (p < 0.001) and higher numbers of many arthropod groups, such as Heteroptera (p < 0.001). Auchenorrhyncha (p < 0.001) and Coleoptera (p < 0.001), important in the diet of farmland birds, were found on all untreated plots. Selective pesticide use is suggested as a method that could help reverse the decline found in many species of farmland bird, by improving the availability of weed and invertebrate food in an intensively farmed landscape.

AB:   The present investigation was undertaken in order to study the influence of ozone, carbon dioxide and water availability on the relationship between grain protein and grain yield in wheat (Triticum aestivum L.). Results were combined from spring wheat, field grown in 16 different open-top chamber experiments, from four different countries. Protein concentration of the grain was negatively (linear) associated with grain yield. This relationship was symmetrical for yield reductions and yield stimulations, despite the fact that the major cause for increases in yield (elevated carbon dioxide concentrations) was different from that causing crop loss (elevated ozone concentrations). The relationship between off-take (the amount of protein taken away from the farmland per unit area) of grain protein and grain yield was clear and highly consistent, but not linear. Yield loss in relation to the reference used (open-top chamber with non-filtered air) was associated with a larger negative change in protein off-take than the positive change in protein off-take corresponding to a yield increase of the same size. The water treatments used in some of the experiments influenced yield and protein content to a very limited extent. It is concluded from the present study that the change of the grain protein from factors such as ozone and carbon dioxide can be explained largely by a simple relationship between grain protein and grain yield at a certain level of nitrogen availability to the plants.

AB:   Propanil N-(3,4,-dichlorophenyl)propanamide is commonly used as a post-emergent herbicide in paddy rice cultivation in Sri Lanka. This study examined propanil concentrations in paddy soil and water, in water and substrate of adjacent wetlands receiving runoff from the paddy and in tissues of two wetland macrophytes common in those wetlands. Field sampling was carried out during the wet season of 1993-1994 and the 1994 dry season. Propanil was detected in paddy soil and in paddy and wetland water samples as late as 14 days after treatment (DAT). It was not detected in the wetland substrate, but relatively high concentrations were found in leaf and stem tissues of the edible plants Ipomoea aquatica and Limnocharis flava 52 DAT in the wet season, but it was not detectable by 132 DAT. Tissue concentrations during the dry season were less consistent. This accumulation and retention by macrophytes may be important factors in reducing propanil concentrations in the wetland water below levels shown to be acutely toxic to other wetland biota. But, propanil so retained may pose a danger to humans who gather and eat these wetland plants regularly and who may, over several months, accumulate sufficient propanil to be harmful to their health.

AB:   The use of cropfields by birds is largely unknown in southern Canada and consequently the risk incurred by pesticide use on bird populations cannot be adequately characterised. The activity patterns and relative interior to edge use of bird species were examined for four crops in southern Ontario to assess the susceptibility of different species to pesticide use. Altogether 138 species were identified in the four crops over the 2 year period but only 25 species were recorded during 50% of visits in at least 1 month: 14 in corn (Zea mays L.), 16 in soybean (Glycine max L. Merr.), 14 in apple (Malus spp.) orchards and eight in vineyards (Vitis spp.). Territorial behaviour was an important activity for several species from May through July in the four crops. Nesting was confirmed in May, June and July for most species, with the exception of American Goldfinch Carduelis tristis, Chipping Sparrow Spizella passerina and Cedar Waxwing Bombycilla cedrorum which nested in August/September. Foraging was the most important activity for most species in all months (7/10 species in May, 6/8 species in June, 4/8 species in July, 5/8 August/September). Few fledgling young were observed. Most species used field edges consistently more often than expected in corn and soybean fields, according to the edge/interior ratio, Yellow Warbler Dendroica petechia being the exception. In apple orchards, relatively few species differentiated between edge and interior. Based on their frequency of occurrence (>50%), behaviour and temporal coincidence with pesticide applications, 13 species were considered most at risk: Killdeer Charadrius vociferus, Horned Lark Eremophila alpestris, American Crow Corvus brachyrhynchos.
       American Robin Turdus migratorius, European Starling Sturnus vulgaris, Chipping Sparrow, Vesper Sparrow Pooecetes gramineus, Savannah Sparrow Passerculus sandwichensis, Song Sparrow Melospiza melodia, Red-winged Blackbird Agelaius phoeniceus, Common Grackle Quiscalus quiscala, Brown-headed Cowbird Molothrus ater and Barn Swallow Hirundo rustica. The latter species, because of its foraging habit, is less likely to be exposed to pesticides. This study was important to identify focal species that can be used for detailed investigations on exposure to pesticides.

AB:   Farming activities can influence bird habitat and wintering patterns. Changes in the wintering habitat use of common crane (Grus grus) were related to changes in land use on this species' traditional migration route in the Western Palaearctics. The study was conducted in the Orellana area (Extremadura, SW Spain), the most important wintering area on this route, where the continued availability of natural food resources (acorns, bulbs, invertebrates) represents a more balanced diet than agricultural resources alone. The presence of crops such as corn (Zea mays L.) is, however, not a critical factor in the area, since the two types of resources, natural and agricultural, are available in the same period of time. The increase in area dedicated to irrigated crops, especially rice (Oriza sp.), affected the growth in the numbers of wintering cranes in the Orellana area. In the past the peak wintering period was in December and was positively correlated to acorn production, whereas the peak period is now in January-February, coinciding with the use of rice-field stubble as feeding places. Dehesas (Mediteranean scrub), cultivated or not, may replace rice-field stubble as feeding places. The existence of intensive farming activity in combination with traditional land-uses is suggested to be the cause of these changes.

AB:   Plant-mediated interactions (i.e., induced resistance) between plant pathogens and insect herbivores were investigated using several pests of the cultivated tomato, Lycopersicon esculentum. Single leaflets of tomato leaves were injured by allowing a third-instar Helicoverpa zea larva to feed on the leaflets or by inoculating the leaflets with Pseudomonas syringae pv. tomato (the causal agent of bacterial speck in tomato; Pst) or with Phytophthora infestans (the causal agent of late blight). Leaflets on separate plants were sprayed with benzothiadiazole, a chemical inducer of resistance to Pst. The effects of these treatments on the resistance of uninoculated or undamaged leaflets to both Pst and H. zea were then assessed after appropriate periods of time. The levels or activities of several defense-related proteins were determined in parallel. Infection of leaflets by Pst decreased the suitability of uninoculated leaflets of the same leaf for both H. zea and for Pst. Similarly, feeding by H. zea caused leaf-systemic increases in resistance to both H. zea and Pst. Infection of leaflets by P. infestans, in contrast, had no effect on resistance of leaflets to H. zea. Treatment of leaves with benzothiadiazole induced resistance to Pst but improved suitability of leaflets for H. zea. Feeding by H. zea caused the systemic accumulation of proteinase inhibitor mRNA and the systemic induction of polyphenol oxidase activity; in contrast, treatment with benzothiadiazole and inoculation with P. infestans caused the systemic accumulation of pathogenesis-related protein mRNA and the systemic induction of peroxidase activity. Inoculation of leaflets with Pst caused the leaf-systemic accumulation of both.
       pathogenesis-related protein and proteinase inhibitor mRNA and the systemic induction of both peroxidase and polyphenol oxidase activity. These results provide clear evidence for reciprocal induced resistance involving certain pathogens and arthropod herbivores of tomato. In addition, these results provide several insights into the integration and coordination of the induced defenses of tomato against multiple pests and suggest that the expression of resistance against some pests may compromise resistance to others.

AB:   Three barley cultivars (Hordeum vulgare L.) were processed into bulgur by pressure cooking or cooking at atmospheric pressure. The effect of processing on levels of thiamine, riboflavin, minerals (Fe, Cu, Zn, Mn, Ca, Mg) as well as the phytic acid and beta-glucan was investigated. Significant decreases (p<0(.)05) were observed in ash, riboflavin and thiamine contents during bulgur processing. Neither the cooking methods nor the dehulling process had significant influence on the content of Fe, Cu, Zn or Mg. However, the Mn and Ca content of the bulgurs were significantly (p<0(.)05) lower compared with the corresponding raw barleys. For all cultivars total P and phytate P contents of the bulgurs were significantly (p<0(.)05) lower compared with the corresponding raw barleys. In contrast, levels of beta-glucan were significantly higher in processed bulgur vs raw barley. Protein contents of the samples did not change significantly during bulgur processing. Bulgur processed from barley appeared to retain most of the nutritional value of raw barley, in particular it showed high levels of soluble dietary fibre.

AB:   The effect of water activity (a(w), 0(.)85-0(.)95), temperature (15-30 degrees C) and incubation period (2-4 weeks) on growth and calorific losses in relation to colonisation by three mycotoxigenic isolates of Aspergillus ochraceus was studied on maize-based substrates. The calorific losses (kJ) of maize flour due to fungal growth in relation to temperature and a(w) were quantified and found to be maximal at 20-30 degrees C (10(.)52-16(.)18%, after 4 weeks at 0(.)95 a(w)), with only slight losses at 0(.)85 a(w) (0-7(.)14%), at both 15 and 20 degrees C. This suggests that growth of mycotoxigenic Aspergillus spp. can significantly contribute to nutritional losses of this staple agricultural food. Calorific values correlated inversely with fungal biomass, with the latter being greatest at 0(.)95 a(w) after both two and four weeks, and maximal at 30 degrees C. Most of the single, two-, three- and four-way interactions of a(w), temperature, time and isolate had a statistically significant (p<0(.)01) influence on calorific losses and fungal biomass.

AB:   The furosine content of infant cereals has been used to evaluate the thermal damage caused to those foods during their manufacture (toasting, amylolysis and drying steps). The mean furosine contents of raw and toasted flours were 13(.)7 and 13(.)8 mg/100 g of protein, respectively. The furosine content increased to 47(.)3 mg/100 g of protein after hydrolysis using alpha-amylase. The amylolysis process raised the reducing sugar content from 0(.)5% for raw samples to 12(.)7%. The furosine content of infant cereals rose to average levels of 500 mg/100 g of protein after roller-drying. The infant cereals with the highest levels of reducing sugars, with or without soy flour, exhibited the highest furosine contents. Furosine is a useful indicator to evaluate the progress of the Maillard reaction during the amylolysis and roller-drying stages of infant cereals manufacture.

AB:   Response surface methodology was used to determine the levels of alpha-amylase, beta-amylase and limit dextrinase enzymes required for efficient conversion of starch to fermentable sugars during mashing. Micro-scale mashes with purified barley starch and malt enzymes were performed in a Brewing Research Foundation mash bath, and mash liquor were analyzed for solubilized starch, reducing sugars (neocuproine assay) and fermentable sugars (anion exchange HPLC). Fermentable sugars in the mash liquor were positively correlated with reducing sugars (R(2)=0(.)94) and the percentage of starch solubilized during mashing (R2=0(.)68). A multiple regression equation relating the levels of the three starch degrading enzymes to the percentage of starch hydrolyzed to fermentable sugars gave a good fit to the second order response surface (R(2) = 1(.)00, RMSE = 1(.)37%). Addition of limit dextrinase to the mashes resulted in a substantial increase in levels of fermentable sugars, and limit dextrinase showed a synergistic effect in increasing levels of maltose in the mash liquor when combined with high levels of beta-amylase. The efficiency of any one starch degrading enzyme in a mash is influenced by the presence of other starch degrading enzymes. Commercial malts contain excess levels of beta-amylase and below optimal levels of limit dextrinase. Malt extract may not be a good indicator of the level of fermentable carbohydrates produced during mashing.

AB:   Starch accumulates in barley (Hordeum vulgare L.) endosperm in large (type A) and small (type B) granules. The sizes, shapes and relative proportions of A and B granules may affect the quality of barley malt for brewing. The objective of this study was to use genetic markers to map quantitative trait loci (QTL) affecting starch granule traits in a cross between a malting barley cultivar, Morex, and a feed barley cultivar, Steptoe. Data on starch granule dimensions were obtained using digital image analysis. With simple interval mapping, a region of chromosome 2 (2H) was found to contain QTL affecting the overall mean granule volume, the proportion of A granules, the mean volume of A granules, the mean maximum diameter of A granules and the mean F-shape of B granules. This region also affected days to heading and plant height, but contained no QTL for grain of malt quality traits. With composite interval mapping, QTL affecting starch granule traits were detected in two additional regions, one on chromosome 4 (4H) affecting the mean F-shape of B granules and one on chromosome 7 (5H) affecting the mean maximum diameter of A granules.

AB:   The development of an in vitro enzymic batch method for pretreatment of cereal samples prior to in vitro fermentation is presented. A statistical experimental design is described and the importance of bile and pepsin for the digestibility of starch was investigated. Day-to-day variation was studied by measuring glucose released and total starch in the digestion residue of rye flour. Four samples, wholemeal rye flour and bread, wholemeal and white wheat breads, were tested to evaluate the performance of the digestion procedure. Pepsin and bile enhanced the hydrolysis of slowly digestible starch. The extent of starch hydrolysis in rye and wheat breads (93-95%) was reproducible and about the same as using thermostable alpha-amylase. More soluble fibers were released from wholemeal rye bread than from the wholemeal wheat bread. The procedure is an efficient method for the removal of starch and protein under physiological conditions prior to in vitro fermentation. The method can also be used as a tool for studying the solubility of dietary fibre (DF).

AB:   The effect of several additives (1(.)215 micromol KIO(3), 0(.)892 micromol cysteine, endo-xylanase and 0(.)5% (w/w) rye-water-extractable arabinoxylans) on changes in the level and glutenin subunit composition of the sodium dodecyl sulphate (SDS)-unextractable protein during breadmaking was investigated. Protein extractability drastically increased during dough mixing and was enhanced both by cysteine and KIO(3). The mixing-induced increase in protein extractability was partly reversed during fermentation. Fermenting doughs containing endo-xylanase had a high level of SDS-unextractable protein than control doughs, while with KIO(3) the amount of SDS-unextractable protein remained very low. During baking most protein became SDS-unextractable. Bread baked from doughs with added KIO(3) contained a significantly higher level of SDS-extractable protein. Changes in subunit composition of the SDS-unextractable glutenin polymers, determined with RP-HPLC, coincided with changes in protein extractability during dough processing. Mixing decreased the ratio of high to low M(r) glutenin subunits. Simultaneously, the relative proportions of the different high M(r) glutenin subunits in the unextractable glutenin polymers changed. During fermentation changes in subunit composition of the SDS-unextractable glutenin were opposite to those during mixing.

AB:   The characterisation of three monoclonal antibodies (Mabs), two raised against a glutenin fraction of wheat storage protein and a third raised against a synthetic peptide conjugate, is described. The three Mabs exhibited broad reactivity as shown by ELISA and immunoblotting. The amino acid sequences constituting the epitopes recognised by each Mab were determined using immobilised pin-bound peptides and were confirmed by using competitive ELISAs with synthesised peptides. By matching the predicted epitopes with published sequences for a number of cereal storage proteins the degree of reactivity of the Mabs was correlated with the frequency with which these epitopes occur. It was possible, therefore, to show that the observed broad reactivity of the antibodies was a function not of the antibodies (which were highly specific) but resulted from structural homology of the gluten proteins.

CC:   Q104
AB:   The nature of the interprotein interactions in wheat gluten is discussed with particular reference to the role of the high molecular weight subunits. It is argued that the high molecular weight subunits interact with each other by disulphide bonds and hydrogen bonds. Dough working favours the formation of end to end disulphide bonds in the subunits and this increases the effective molecular weight of the subunit and hence the number of protein-protein interactions. Association of the subunits can also take place by interchain hydrogen bonding. So many hydrogen bonds are formed that not all can be broken simultaneously although there will be unbonded mobile regions (loops) and bonded regions (trains). Stretching extends loops and then causes the proteins to slide over one another. The elastic restoring force is provided by the re-establishment of the loop train equilibrium.

AB:   Small angle X-ray scattering in solution was performed on seed-storage proteins from wheat. Three different groups of gliadins (alpha-, gamma-, and omega-) and a high molecular weight (HMW) subunit of glutenin (1BX20) were studied to determine molecular size parameters. All the gliadins could be modelled as prolate ellipsoids with extended conformations. The HMW subunit existed as a highly extended rod-like particle in solution with a length of about 69 nm and a diameter of about 6.4 nm. Specific aggregation effects were observed which may reflect mechanisms of self-assembly that contribute to the unique viscoelastic properties of wheat dough.

AB:   Transgenic rise (Oryza sativa L.) lines were generated through particle-bombardment-mediated transformation. Hygromycin phosphotransferase (hpt) was used as a selectable marker gene on co-integrate plasmids containing either one or two unselected genes, the Bialaphos-resistance gene (bar) coding for phosphinothricin acetyltransferase and the beta-glucuronidase gene (gus A), respectively. Transformants were analyzed to determine possible correlation between expression, integrated transgene copy number and/or complexity of integration patterns. We observed that an increase in transgene copy number did not always lead to a concomitant decrease in expression levels or to silencing through co-suppression. Transgenic line with four to five copies of integrated transgenes expressed the protein product of both unselected genes stably and at levels comparable to transformants with one or two copies. In the majority of lines we analyzed, expression patterns of the two unselected genes were similar. In lines where transgene silencing was observed, this was independent of position effects. In specific cases, silenced transgenes could be reactivated by treatment with 5-azacytidine, suggesting methylation of cytosine residues. We report that methylation of cytosines may not spread to adjacent regions, hence other transgenes in the vicinity of the silenced transgene remain active. By comparing the structure of transgenic loci with expression patterns of introduced genes, we concluded that the integrity of integrated transgenes was a major factor in the onset of silencing. We observed that the presence of truncated sequences of transgenes capable of generating incomplete transcripts, resulting in aberrant RNA.
       species, may be responsible for silencing.

AB:   Anthocyanin synthesis in Sorghum bicolor Moench induced by a low-fluence response of phytochrome (phy) is multiplicatively amplified by a cryptic red-light signal (CRS) produced by red light (R). The photoreceptor for CRS and its features in CRS production were studied. (i) An action spectrum determined with a 200-s light pulse of wavelengths from 347 to 693 nm had peaks at 657 and 378 nm. (ii) The CRS-producing effect of R, even as short a pulse as 20 s, was neither suppressed by an immediately subsequent far-red light (FR) pulse nor increased by placing a dark interval of 180 s between R and FR; simultaneously FR, however, suppressed the R action in accordance with the resulting ratios of the FR-absorbing form (Pfr) to total phy. (iii) The effect of R increased with increasing fluence rate to plateau at the same fluence rate regardless of the pulse length, but the level of this plateau depended on the pulse length. (iv) The effect of R increased with increasing pulse length when compared at the same fluence, whether saturating or unsaturating; thus, no reciprocity law holds. These results indicate that the photoreceptor for CRS production is a phy, Pfr being active, which presumably shows very fast dark reversion to the R-absorbing form without absorbing FR. The possible CRS-production mechanism of the phy and its significance in the so-called R high-irradiance response of phy are discussed.

AB:   Potassium is taken up by maize (Zea mays L.) coleoptile cells via a typical plant inward rectifier (K(ir)). Sufficient conductance of this channel is essential in order to maintain auxin-stimulated cell elongation. It was therefore investigated whether the activity of this channel is subject to direct or indirect control by this growth hormone. Patch-clamp measurements of whole coleoptile protoplasts revealed no appreciable effect of externally applied 10 micromolar or 100 micromolar alpha-napththaleneacetic acid (NAA) on the activity of K(ir) over test periods of greater than or equal to 18 or greater than or equal to 8 min, respectively. When, however, K(ir) was recorded in the cell-attached configuration and 10 micromolar NAA administered to the bath medium, the conductance of K(ir) increased significantly in 13 out of 18 protoplasts over the control. The rise occured at a fixed protoplast voltage after a lag period of less than 10 min and exhibited no voltage dependency. The absence of response to NAA of protoplasts in the whole-cell configuration indicates that auxin perception and channel control is linked via a soluble cytoplasmic factor and that this mediator is washed out or modified upon perfusion of the cytoplasm with pipette solution. To search for this expected diffusible factor the K(ir) current was recorded before and after elevation of Ca(2+) and H(+) in the cytoplasm. In the whole-cell configuration the increase in Ca(2+) from a nanomolar value > 1 micromolar by means of Ca(2+)-release from the caged precursor Na(2-)DM-nitrophen left K(ir) unaffected. The whole-cell K(ir) conductance was also not affected upon addition of 10 mM Na(+)-acetate to the bath medium, or.
       operation used to lower the cytoplasmic pH. This excludes a primary role for the known auxin-evoked rise in cytoplasmic Ca(2+) and H(+) in K(ir) activity. We postulate that another, as yet unknown, mechanism mediates the auxin-evoked stimulation of the number of active K(ir) channels in the plasma membrane.

AB:   The induction and substrate specificity of cinnamyl alcohol dehydrogenase, (CAD, EC 1.1.1.195) was investigated in relation to the deposition of a defensive, syringyl-rich lignin at wound margins in wheat (Triticum aestivum L. cv. Brigadier). Column chromatography of untreated, wounded and elicitor-treated tissues revealed three major CAD forms (CAD-A,-B and -C) of which only CAD-C was responsive to elicitors. Examination of the substrate preference of these fractions indicated p-coumaryl alcohol to be the preferred substrate of CAD-A and CAD-B, whereas sinapyl alcohol was favoured by CAD-C. Activity-stained isoelectric focusing gels revealed in untreated and wounded leaves four CAD isoenzymes with esoelectric points of 4.59 (i), 4.67 (ii), 4.81 (iii), 4.93 (iv). Elicitor treatment generally enhanced the staining of all isoenzymes and resulted in the appearance of two new isoenzymes of 5.22 (v) and pI 5.31 (vi). In activity stained non-denaturing PAGE gels, CAD-C further resolved into two distinct zones of CAD activity. Cinnamyl alcohol dehydrogenase-C was purified to apparent homogeneity and characterisation revealed a 45-kDa subunit peptide which in its native form demonstrated a marked substrate preference for sinapyl alcohol. Overall, the differential induction and substrate preference of CAD-C are consistent with a defensive role during defensive lignifications at wound margins in wheat.

AB:   Glutathione-dependent formaldehyde dehydrogenase (FDH; EC 1.2.1.1 has been purified 3900-fold from maize cell-suspension cultures to a specific activity of 4.68 micromol (mg protein)-1 min (-1). The homogeneous enzyme consisted of two identical subunits with a molecular mass of 42 kDa, and an isoelectric point of 5.8. Eight tryptic peptides were sequenced and gave a perfect fit to the protein sequence derived from maize Fdh cDNA (J. Fliegmann and H. Sandermann, l997, Plant Mol Biol 34: 843-854). There was 62% identity with the eucaryotic FDH consensus sequence. Michaelis constants of approx. 20 micrometer (formaldehyde), approx. 50 micrometer approx. 31 micrometer (NAD+) were determined for the maize enzyme as well as for FDH partially purified from dog lung. Besides S-hydroxymethylglutathione pentanol-1, octanol-1, and omega-hydroxy fatty acids served as substrates for both FDH preparations. The unusual substrate specificity indicates that FDH may be involved in the detoxification of long chain lipid peroxidation products.

AB:   The historical association of white kernel color in wheat with susceptibility to preharvest sprouting and the comparative mapping information suggesting the possible involvement of maize (Zea mays L.) vivipary 1 were used as the basis for isolation and characterization of the wheat homologue. Consensus primers were designed based on conserved regions of the gene in rice (Oryza sativa L.), maize, and Arabidopsis. These primers were used to amplify a portion of the wheat vivipary 1 gene for sequencing and analysis. A comparison of sequence similarity between maize, rice, wheat (Triticum aestivum L.) and barley (Hordeum vulgare L.) revealed that exons 1 and 6 are highly diverged among all the species. Sequence divergence for rice/maize/barley comparisons are similar across all exons. Comparisons with wheat indicate a trend for exons 2 and 5 to be slightly less conserved leading to lower sequence similarity overall for wheat. Barley sequences were all closely related to wheat, even for exon 6. If additional mapping data support a recent report that Vp1 is not responsible for red kernel color in wheat, this could facilitate enhancement of grain dormancy in white wheat by allowing manipulation of vivipary 1 without affecting kernel color.

AB:   This study was conducted to measure variability in results of germination tests, to estimate tolerances needed to cover variation in test results, and to determine the minimum number of seeds required for producing germination results within the limits of established tolerances. Data were collected from conventional germination referee (CGR) tests on corn (Zea mays L.) and soybeans (Glycine max (L.) Merrill), conducted by up to 46 Association of Official Seed Analysts (AOSA) and Society of Commercial Seed Technologists (SCST) laboratories in the Midwest and Upper Great Lakes Region in 1994 to 1996. In 1997, a "blind germination referee (BGR) test" was conducted on the same crops by 23-25 laboratories in the same region in which the individual replicates of the same seed lots were unknown to the analysts performing the test. A positive "inter-replicate bias" in which a significant correlation existed among the results of replicate tests occurred in the CGR but not in the BGR tests. Tolerance limits calculated for germination above 90% from both CGR and BGR test results were close to International Seed Testing Association (ISTA) Rules, but lower than those in the AOSA Rules. Tolerances calculated for germination levels below 90% from both CGR and BGR test results were generally higher than both the AOSA and ISTA tolerances. The greatest decline of test variability was observed when sample sizes were increased from one 100-seed replicate to two 100-seed replicates.

AB:   Hemicellulose powder from American corn bran (Zea mays L), substantially a feruloylated arabinoxylan polysaccharide, can be converted with peroxidase and hydrogen peroxide under controlled conditions to form thermostable biogels. Previously it has been shown that gel formation involved the oxidative coupling of ferulic acid to form a series of ferulic-acid dimers. In the present study, differential scanning calorimetry showed that the effect of such cross-linking was to elevate the glass transition temperature (Tg) which also shifted to lower temperatures with increasing water content.

AB:   The composition and carbohydrate structure of hemicelluloses namely branan ferulate isolated from maize bran has been determined. This novel polysaccharide material is the base polysaccharide of Sterigel, a Seton Scholl preparation which is being used successfully as a wound management aid. The structure of the polysaccharide was determined by methylation followed by GC-MS analysis, and 1H- and 13C-NMR spectroscopic analysis. It was shown to be composed of a (1 leads to 4)-beta-D-xylan backbone substituted with a variety of side-chain components, such as single alpha-D-glucuronic acid residues (via an alpha-D-GlcA-(1 leads to 2)-linkage to the xylan backbone), single alpha-L-arabinose residues (via alpha-L-Araf-(1 leads to 2)- and/or alpha-L-Araf-(1 leads to 3)-linkages to the xylan backbone) and longer chains of 2-3 monosaccharide residues containing arabinose, xylose and galactose (in the form alpha-D-(Galp-(1 leads to 4)-beta-D-Xylp-(1 leads to 2)-alpha-L-Araf, linked to the xylan backbone via alpha-L-Araf-(1 leads to 2)- and/or alpha-L-Araf-(1 leads to 3)-linkages). In addition to the carbohydrate, non-carbohydrate moieties such as hydroxy-cinnamic acids and some proteins, detected using scanning UV spectroscopy (190-450 nm), are present in the branan ferulate. The hydroxycinnamic acids appear to be bound to the polysaccharide chains via ester linkages between their carboxylic acid groups and the C-5 hydroxyl group of a proportion of the alpha-L-Araf residues, the location of which are detailed above. Predominantly trans-ferulic acid (0.38% w/w), and small amounts of cis-ferulic acid (0.06% w/w) and trans-p-coumaric acid (0.02% w/w) were extracted with ethyl acetate after hydrolysis using.
       2 M NaOH and identified using GC and GC-MS. Hydrolysis with an aryl ester hydrolase (EC 3.1.1.2) was carried out to confirm the presence of the ferulate ester linkages. HPLC results confirmed that the ferulic acid is released by the enzyme (0.25% w/w). GPC analysis using UV (280 nm) and RI detection confirmed that the ferulic acid was bound to the polysaccharide chain since the distributions directly overlapped, indicating the presence of little or no free ferulic acids. Indeed, free ferulic acid contents of <0.02% w/w were determined in extracts of solid branan ferulate and an aqueous solution of branan ferulate, by HPLC.

AB:   The potential of manganese peroxidase (MnP) from Phanerochaete chrysosporium to cross-link wheat arabinoxylans, and to covalently link cysteine and tyrosine to the ferulic acid esterified on arabinoxylans, was investigated. MnP was able to gel arabinoxylans by oxidative coupling of their feruloyl groups, with concominant formation of dehydrodimers of ferulic acid. Whereas at high concentrations cysteine delayed gelation, at low concentrations it had no effect. Tyrosine did not affect gelation, but it accelerated the consumption of ferulic acid. The MnP was compared to laccase from Pycnoporus cinnabarinus and the couple hydrogen peroxide/horseradish peroxidase (H2O2/POD).

AB:   Feruloyl esterase activity has been detected in barley grain and germinated barley. No differences have been found between the values of activity against methyl ferulate in barley crude extracts (1.05 +/- 0.10 mU mg-1 protein) with and without sterilisation (P > 0.05), indicating that the activity is native to the barley grain rather than due to microbial contamination. The highest value of esterase activity was detected after 2 day growth, although an overall downward trend was observed over a 6 day germination period at 25 degrees C. The Km and Vmax of the crude barley esterase/s on methyl ferulate were 0.34 +/- 0.05 mM and 0.76 +/- 0.03 mU mg-1 protein, respectively. The crude extracts were also active upon the methyl esters of sinapic, p-coumaric and caffeic acids, and upon a feruloylated arabino-oligosaccharide (Ara2F), but not upon the methyl ester of vanillic acid.

AB:   Sugar beet pulp (SBP) is a waste product of the sugar industry which is rich in ferulic acid. Few ferulic acid esterases (FAEs) that are capable of releasing ferulic acid from SBP or from SBP soluble feruloylated oligosaccharides (SFO-SBP) have been described. Streptomyces avermitilis CECT 3339 was grown in medium containing SBP or destarched wheat bran (DSWB) as the carbon source. FAE activity was evaluated in terms of the micro-organism's capacity to release ferulic acid from DSWB, SBP, SFO-DSWB and SFO-SBP. S avermitilis showed FAE activity in both media and was able to release ferulic acid from DSWB, SFO-DSWB and SFO-SBP. A comparison of the FAE activity detected in each medium indicated that different activities were induced by each type of carbon source.

AB:   Barley spent grain is a residue from the brewing process. In this paper, four different commercial enzyme preparations (Viscozyme L, Ultraflo L, Termamyl and Lallzyme) were tested for their ability to release hydroxycinnamic acids, ferulic acid (FA) and p-coumaric acid (PCA), from barley spent grain. The cinnamic acid esterase activities of the enzyme preparations were measured against the model substrate methyl ferulate. Termamyl was the only enzyme preparation that showed no esterase activity. Incubation of Ultraflo L (1.3 U g-1 substrate, 24 h) with barley spent grain released 70% of the total alkali-extractable FA and 8% of the total alkali-extractable PCA. Under the same conditions, Viscozyme L and Lallzyme released, respectively, 33 and 55% of the total alkali-extractable FA, and 0.8 and 1.6% of the total alkali-extractable PCA. For FA release, enzyme concentrations higher than 1.3 U g-1 were saturating. However, for the release of PCA, a continuos increase was observed until 13 U g-1. The percentages of the FA released by Viscozyme L, Ultraflo L and Lallzyme were higher than those obtained by pure ferulic acid esterases. These three enzyme preparations could be employed for the effective release of hydroxycinnamic acids from barley spent grain.

AB:   Dehydrodimers of hydroxycinnamic acids, such as ferulic and p-coumaric acids, are important structural components which serve to cross-link polymers in plant cell walls. Dehydrodiferulate oligosaccharide diesters were solubilised from wheat bran or sugar beet pulp by treatment with Driselase and release of dehydrodiferulic free acids from this substrate by purified feruloyl esterases was analysed by HPLC. We detected 5-5diFA, 8-O-4diFA and 8-5BendiFA in saponified extracts from wheat bran and sugar beet pulp. Driselase-treatment solubilised 21 and 97% of the saponifiable dehydrodimers from wheat bran and sugar beet pulp, respectively, but only as dehydrodiferulate esters, not as dehydrodiferulic acids. At low concentrations, feruloyl esterase A (FAEA) from Aspergillus niger and an esterase (XylD) from Pseudomonas fluorescens released 93% and 36% of the saponifiable 5-5diFA from solubilised wheat bran, respectively, but only 12 and 15% from solubilised sugar beet pulp. At higher concentrations, only FAEA also released 8-O-4diFA (65%) from solubilised wheat bran, but not sugar beet pulp. We could not detect release of any dehydrodiferulic acids from solubilised wheat bran or sugar beet pulp using either a cinnamoyl ester hydrolase from Piromyces equi (CEH) or from A niger (CinnAE). Our results demonstrate that FAEA and XylD hydrolyse dehydrodiferulate diesters to release the free acids, which means they have the potential to break the putative cross-links present in graminaceous monocot and dicot cell walls, while two other feruloyl esterases (CinnAE and CEH) did not release dehydrodiferulic acids from plant cell walls.

AB:   An experiment was conducted in order to investigate hay yield and nitrogen harvest in binary smooth bromegrass (Bromus inermis Leyss cv. Tohum Islah) mixtures with alfalfa (Medicago sativa L. cv. Kayseri) and red clover (Trifolium pratense L. cv. Tohum Islah) in Erzurum, Turkey for 5 years between 1991 and 1995. The Hay yield, nitrogen harvest, protein concentration and land equivalent ratio (LER) in the mixtures with alternating rows of 1:1, 2:1 and 1:2 of smooth bromegrass with alfalfa and red clover were compared to those in pure legume stands without any N-fertilizer application or pure smooth bromegrass stands that received 0, 50, 100 and 150 kg ha-1 N. The mixtures had no N fertilization apart from 40 kg N ha-1 in the establishment year. The dry matter production in all the mixtures receiving no N fertilizer application was higher than in pure legume stands. Pure grass stands were sustained only with the application of 150 kg ha-1 N. The highest hay yields were obtained from the mixtures of smooth bromegrass (Sb) with red clover (Rc) (2Rc 1Sb) (14.65 t ha-1) and with alfalfa (A) (1A 1Sb) (14.49 t ha-1). Although N application increased Sb yields in pure stands, the highest yields obtained with N fertilization were still lower than the yields in the mixtures without N application. The superiority of the mixtures was also reflected by their large N harvests (e.g. 355.9 kg N ha-1 in 2Rc 1Sb plots) compared to pure Rc (317.8 kg N ha-1), pure A (294.3 kg N ha-1) and pure Sb stands that received 150 kg N ha-1. The nitrogen harvest increased in pure Sb plots as the N doses applied increased. Furthermore, the protein concentration of the hay from the mixtures (158.2-165.7 mg g-1) was equal to.
       that of the pure A stands (165.7 mg g-1) and higher than that of pure Sb stands (122.9 mg g-1 at 150 kg N ha-1 application) although the hay from pure Rc plots had the highest protein concentration (179.3 mg g-1). The LER values were also higher in the mixtures (e.g. 1.28 in 1A 1Sb and 1.28 in 2Rc 1Sb plots) compared with the pure stands. The mixture plots also had a more balanced temporal distribution of hay. The grass component was more productive in early spring, whereas the legume fractions grew better in the summer. In conclusion, for a sustainable production of high-quality hay and greater N harvests without using N fertilizers, binary mixtures of Sb with A in alternating rows (1A 1Sb) were recommended for long-purpose stands and in alternation with double red clover rows (2Rc 1Sb) for short purpose stands under similar conditions. N application could be eliminated in the grass-legume mixtures without any yield depression.

AB:   A dynamic soil-crop model was developed to predict the date on which N deficiency occurs for winter wheat crops in the temperate climate of Northwest Europe. It is based on the daily simulation of soil N supply and crop N requirement for the period during which N-fertilizer is usually applied to wheat crops, the end of winter until flowering. The soil sub-model was derived from the 'balance-sheet method' used in France for nitrogen fertilization recommendations. It describes the net mineralization of various sources of organic matter (soil humus, crop residues, organic products). The crop sub-model simulates crop biomass production and its nitrogen content using a radiation use efficiency model and a critical dilution curve for nitrogen content. Both soil and crop sub-models require few parameters and inputs, most of which are readily available on commercial farms, together with daily climatic data. The model tested with various rates and timings of N application in three experiments accurately simulated the date on which nitrogen deficiency began in wheat crops. The interest in using the model for tactical and strategic approaches is discussed.

AB:   The concentration of phenolic acids and in situ disappearance of cell wall (CWISD) of normal maize and bm1, bm2, bm3 and bm4 mutants were evaluated in whole stem and stem sections at the silking and silage stages. At the silking stage, the CWISD of bm1 was similar to that of normal maize while that of bm2, bm3 and bm4 was greater; p-coumaric acid and lignin concentrations were lower in the mutants while ferulic acid varied little. At the silage stage, the composition was slightly altered but the CWISD of the mutants was notably reduced, possibly because of condensation reactions occuring with ageing. The mid-internode was the most similar in composition and degradability to the whole stem.

AB:   Release of phenolic acids from ground rye (Secale cereale L) grain was investigated using different commercial plant cell wall degrading enzyme preparations. The yields obtained were quantified using an improved HPLC procedure developed for analysing hydroxycinnamic and hydroxybenzoic acids in ground rye grain. The commercial enzyme preparations were able to release up to 70% of the alkali-extractable ferulic acid during hydrolysis at conditions relevant to fermentation of rye dough. The data indicate that commercial plant cell wall degrading enzymes may be applicable for increasing the content of free phenolic acids in rye bread.

AB:   For economic and ecological reasons, the chilling tolerance of maize must be further improved. This seems to be possible by the introgression of tropical highland germplasm if chilling and heat tolerance can be combined to obtain a high yield consistency. Two adapted and two semi-exotic highland varieties were grown at 16, 25 and 30 degrees C until the third and sixth leaf stage. Thereafter, some plants were transplanted and grown at 24 degrees C in the glasshouse until anthesis. Exotic germplasm improved the leaf appearance and shoot growth during the early heterotrophic phase at all temperatures, with a marked advantage at low temperature. This superiority was almost completely lost during the succeeding autotrophic growth phase with some residual effects at low temperature and a marked relative retardation in leaf appearance and growth at high temperature. Relative growth rates (RGR) of exotic germplasm were not superior at low temperature or inferior at high temperature. At low temperature, their comparatively reduced leaf area ratio (LAR) was still compensated by a high net assimilation rate (NAR). Their expression of the latter trait was comparatively decreased at a high temperature, which explained the low RGR. Early growth at low and medium temperatures had similar effects on final leaf number for all varieties; a high temperature increased the final leaf number up to 20%, especially in exotic germplasm. In conclusion, the good early vigor of Mexican highland germplasm seems to be mainly restricted to the heterotrophic phase; a relation to adaptative mechanisms, such as a low LAR, must be overcome for an efficient utilization in conventional breeding.

AB:   Ceramic suction cups were used to measure nitrogen (N) leaching over three consecutive winter periods from a long established ley-arable rotation experiment. We examined four treatments: 3-year all-arable, grass-clover ley and grass ley each followed by two seasons of arable test crops and an 8-year grass ley that remained as grass throughout our study. Four rates of fertilizer N were applied to sub-plots of the test crops. Our primary objective was to compare the effect that the rotations had on N leaching from the arable test crops. Cultivation of the 3-year grass and grass/clover leys and the sowing of winter wheat did not create a major flush of net N mineralization because of the unusually dry autumn weather. In the first winter following sward destruction, although the concentration of N in drainage following the grass/clover was low, it was significantly greater than that following the grass, which was greater than that from the continuous grass treatment. In contrast, the concentration and quantity of N in drainage from the all-arable treatment was at least five times greater than any other treatment. This was due to earlier and more rapid N release from the residue of the preceding arable crop. In the winters after harvest of the cereal test crops (i.e. the second and third season of measurements), the peak drainage N concentrations were similar in all treatments (20 microgram NO3(-)N ml-1). The amount of N leached was not related to fertilizer addition. Over the full 5-year rotation, we found that the rotations that included a ley were better at conserving N; the estimated annual N leaching losses from the all-arable, grass, grass/clover and continuous grass were 29, 17, 17 and 2 kg N ha-1.
       year-1, respectively. On all treatments, but especially the grass-clover fey, the greatest rate of fertilizer addition caused a yield reduction. The N-balance indicates a considerable net immobilization during this study under the sub-plots of the arable test-crops that received N fertilizer. This corresponds to similar results of N-balance studies on other long-term experiments.

AB:   Cobalt, nickel and strontium were introduced via flaps into leaf laminas or into the stem of maturing, intact winter wheat (Triticum aestivum L., cv. 'Arina') grown under natural conditions in a field. Long-distance transport of these elements and the influence of the application date and of different application positions were investigated. The dry-matter accumulation in the grains was not markedly affected by the treatments as compared to untreated control plants. The phloem-immobile strontium served as a marker for the distribution of the xylem sap in the plants. After foliar application, nickel accumulated more rapidly and in higher quantities in the grains than cobalt. Therefore, nickel has a slightly better phloem mobility than cobalt. Regardless of the application date, a higher percentage of the two elements was transported from the flag leaf lamina than from the second or third lamina from the top to the grains. These results indicate that the leaf position is highly relevant for the transfer of the heavy metals investigated to the ear. Introduction into the stem led to a higher accumulation of nickel and cobalt in the grains than introduction into one of the leaves. An earlier feeding date caused a higher accumulation of nickel and cobalt in the grains when introduced into the stem. In contrast, no major differences between earlier and later feeding dates were detected when the elements were introduced into the leaves. Losses of the applied elements were detected during maturation and can be explained by leakage in the rain.

AB:   Ferulate polysaccharide esters in grasses enter into free-radical condensation reactions in the cell wall. By radical dimerisation of ferulates, polysaccharide-polysaccharide cross-linking is effected. A range of diferulate isomers are produced, not solely the 5-5' -coupled dimer which has been quantified historically. Both ferulates and diferulates enter lignification reactions and become intimately bound up with the lignin complex. Again, under-quantification is significant since it is not possible to release ferulate or diferulates from some of the structures. Overall, ferulates play a significant role in cell wall development and impact polysaccharide utilisation in grasses.

AB:   Pasture legumes are used as a source of biologically fixed N2. Several methods have been used to evaluate the amount of N2 fixed in mixed pastures, but none is considered clearly superior. In an Eutric Leptosol of southern Portugal, N2 fixation by subterranean clover mixed with grasses was evaluated over 2 years and subjected to several cuts by 15N dilution (ID), natural 15N abundance (NA) and N difference (ND) techniques. The amount of fixed N2 in subterranean clover determined by natural 15N abundance with correction for isotopic fractionation ranged from 32 kg N ha-1 in 1992/1993 to 37 kg N ha-1 in 1993/1994. Assuming that no isotopic fractionation occurred during fixation (B = 0 per thousand), fixation capacities at around 80% of nitrogen derived from the atmosphere (Ndfa) were found by the natural 15N abundance technique. However, with correction for isotopic fractionation during N2 fixation (B = -1.13 per thousand), fixation capacities closer to 50% Ndfa were obtained, similar to the value obtained in the second-year experiment with the isotopic dilution method. In year 1, the fixation capacity, as estimated by the isotopic dilution method, was about 37% Ndfa. The nitrogen difference (clover N-grass N) calculations underestimated the amount of N2 fixed in 1992/1993. This method assumes that both legumes and non-legumes absorb the same amount of N from the soil, which may not be true. Also, only the above-ground legume herbage was analyzed in this experiment. From the results, either ID or NA methods, particularly with a correction for the B-value, can be used to estimate N2 fixation in mixed pastures, rather than the ND method. The natural 15N abundance (NA) technique can.
       be more versatile than the ID technique, allowing frequent sampling in undisturbed grassland ecosystems with reduced costs. Nitrogen fixation decreased in June, in both years, probably due to a lower soil water content and higher soil temperature.

AB:   In order to limit overproduction and pollution risks, low N fertiliser agricultural systems are likely to be advocated in Europe. An experiment was carried out in 1994 and 1995 to compare N uptake and N utilisation of two-rowed and six-rowed winter barley (Hordeum vulgare L.). Two sets of two-rows and six-rows, composed of 12 varieties each, were cultivated in northern France on a haplic luvisol without (N1) and with 100-110 kg/ha (N2) N fertiliser. Mean grain yield was 596 g/m2 at N1 and 779 g/m2 at N2. On average six-rows outyielded two-rows by 4% (34 g/m2) at N2 and 11% at N1 (70 g/m2). Ears/m2 was the yield component which fell most sharply between N2 and N1 (718 and 510 ears/m2 on average). Six-rows had fewer ears/m2 at both N levels but they lost more ears than two-rows (-33% and -26%, respectively). While the number of grains/ear was approximately the same for two-rows at both N levels (21.9 grains/ear on average) in 1995, it was significantly higher at N1 than at N2 for six-rows (44.7 and 38.5, respectively). Thousand kernel weight was higher at N1 than at N2, the difference being higher for six-rows (+7%) than for two-rows (+4%). N uptake efficiency (total plant N/soil N supply) was identical at N2 and higher for sixrows at N1 in 1995. Total N utilisation efficiency (total above-ground dry weight/total plant N) was equal at both N levels. HI (grain yield/total above-ground dry weight) was higher at N1 in both years and at N2 in 1994 for six-rows. Six-rows outyielded two-rows at high and low N levels. This was therefore associated mainly with higher HI and not with better N uptake or utilisation efficiency.

AB:   Enzymatic hydrolysis of sugar-beet pulp, and subsequent isolation of feruloylated oligosaccharides, has shown that ferulic acid groups are ester-linked mainly on O-2 of arabinose residues and on O-6 of galactose residues in the pectin side-chains. After saponification of sugar-beet pulp enzymatic digests, dehydrodiferulic acids (0.14%, w/w) have also been identified and characterised as 8-5', 5-5', 8-8' and 8-O-4' isomers, suggesting that covalent cross-linking of pectic polysaccharides through diferulic bridges occurs in sugar-beet pulp. Feruloylated oligosaccharides from the side-chains of heteroxylans have been isolated from maize bran by acid hydrolysis. Ferulic acid is esterified on O-5 of arabinofuranose residues. 8-8', 8-5', 8-O-4' and 5-5' coupled dimers, which represent 2.5% (w/w) of the bran, have also been detected. It has been calculated that, in the cell wall, each heteroxylan macromolecule bore approximately 75 esterified ferulic acid groups and could be cross-linked through approximately 30 diferulic bridges. This result suggests a high degree of cross-linking of heteroxylans chains through ferulic acid in maize bran cell walls.

AB:   Oat flour has preserving properties that have been attributed to the antioxidant activity of phenolic compounds, particularly hydroxycinnamic acid conjugates. This work compares extraction methods based on methanol and propan-2-ol for the removal of oat antioxidants from milled oats. The efficiency of the extraction method was determined by measuring the concentration of total phenolic compounds and the antioxidant activity based on an oxidation reaction of beta-carotene with linoleic acid in an emulsion. A novel method was also used based on the quenching of light generated from the chemiluminescence reaction between cytochrome c, tert-butylhydroperoxide (t-BHPO) and luminol. The chemiluminescence method proved to be reliable, rapid and sensitive. Both propan-2-ol and methanol extraction methods yielded oat extracts with antioxidant activity. The propan-2-ol extract contained approximately 70% of the activity measured in the methanol extract. Despite the lower yield, the industrial advantages of the latter method are discussed.

AB:   Transgenic wheat plants containing the gene encoding snowdrop lectin (Galanthus nivalis agglutinin; GNA) under the control of constitutive and phloem-speciflc promoters were generated through the particle bombardment method. Thirty-two independently derived plants were subjected to molecular and biochemical analyses. Transgene integration varied from one to twelve estimated copies per haploid genome, and levels of GNA expression from 0 to ca. 0.2% of total soluble protein were observed in different transgenic plants. Seven transgenic plants were selected for further study. Progeny plants from these parental transformants were selected for transgene expression, and tested for enhanced resistance to the grain aphid (Sitobion avenae) by exposing the plants to nymphal insects under glasshouse conditions. Bioassay results show that transgenic wheat plants from lines expressing GNA at levels greater than ca. 0.04% of total soluble protein decrease the fecundity, but not the survival, of grain aphids. We propose that transgenic approaches using insecticidal genes such as gna in combination with integrated pest management present promising opportunities for the control of damaging wheat pests.

AB:   Proteinase inhibitors have been proposed to function as plant defence agents against herbivorous pests. We have introduced the barley trypsin inhibitor CMe (BTI-CMe) into wheat (Triticum aestivum L.) by biolistic bombardment of cultured immature embryos. Of the 30 independent transgenic wheat lines selected, 16 expressed BTI-CMe. BTI-CMe was properly transcribed and translated as indicated by northern and western blot, with a level of expression in transgenic wheat seeds up to 1.1% of total extracted protein. No expression was detected in untransformed wheat seeds. Functional integrity of BTI-CMe was confirmed by trypsin inhibitor activity assay. The significant reduction of the survival rate of the Angoumois grain moth (Sitotroga cerealella, Lepidoptera: Gelechiidae), reared on transgenic wheat seeds expressing the trypsin inhibitor BTI-CMe, compared to the untransformed control confirmed the potential of BTI-CMe for the increase of insect resistance. However, only early-instar larvae were inhibited in transgenic seeds and expression of BTI-CMe protein in transgenic leaves did not have a significant protective effect against leaf-feeding insects.

AB:   Proteinase inhibitors are widely distributed in animals, plants and microorganisms and their roles in plants are associated with defense against pests. The utilization of proteinase inhibitors for crop protection has been actively investigated with a variety of proteinase inhibitors. Soybean Kunitz trypsin inhibitor (SKTI), one of the major seed storage protein, is synthesized for a short period during seed development. To investigate the role of SKTI in a plant's defense system against insect predation, a recombinant plasmid containing the full-length cDNA of SKTI under control of the CaMV 35S promoter was introduced into rice protoplasts by using the PEG direct gene transfer method and a large number of transgenic rice plants were regenerated. The integration, expression, and inheritance of this gene was demonstrated in R1 and R2 generations by Southern, northern, and western analyses. Accumulation levels (0.05-2.5% of soluble proteins) of SKTI protein were detected in R1 and R2 plants. Bioassay with R1 and R2 transgenic plants revealed that transgenic plants are more resistant to destructive insect pest of rice, brown planthopper (Nilaparvata lugens Stal), than the control plants. Thus, introduction of SKTI into rice plants can be used to control insect pests.

AB:   The acetyl bromide assay was developed to provide a rapid and sensitive method for quantifying lignin in woody plant species. The original procedure cautioned against prolonged reaction times and advised keeping the reaction temperature at 70 degrees C to prevent excessive carbohydrate degradation that would skew the absorption spectra. Characterization of the reaction conditions revealed that the acetyl bromide reagent readily degrades xylans, a prominent polysaccharide group within all lignified plants. This degradation results in increased absorbance in the 270-280 nm region that is used to quantify lignin. The degradation of xylans is temperature dependent and is exacerbated by the addition of perchloric acid. Lowering the reaction temperature to 50 degrees C and increasing the reaction time from 2 to 4 h allows complete lignin solubilization but minimizes degradation of the xylans.

AB:   A procedure has been described for the large-scale micropropagation of three Phragmites species, P. karka, P. communis and P. australis, from axillary buds excised from the main and side branches. Position of the buds on the branches had an effect on the bud break and establishment of the cultures under in vitro conditions. Lower buds of P. australis and middle buds of P. karka and P. communis were the most suitable. The presence of yeast extract as one of the ingredients of the sprouting medium helped in the early detection of systemic contamination. Multiple shoot formation and root initiation were obtained on Murashige and Skoog's basal medium supplemented with different concentrations of BA--0.5 mg/l for P. karka, 0.25 mg/l for P. communis and 0.1 mg/l for P. australis--0.5 mg/l Kn and 2% sucrose (w/v). Shoots and roots elongated on half-strength MS basal medium with 2% sucrose but without any plant growth regulators. A zone of root hair was observed in the case of P. australis. Hardening occurred on 95% of the plantlets within 30 days of transfer to the polyhouse. Over 10,000 plants were produced from three buds of each species within 9 months. The plants were supplied to a private company for their industrial waste treatment.

AB:   Fumonisins, a family of mycotoxins produced by Fusarium moniliforme and Fusarium proliferatum, are found in maize worldwide and have been associated with animal diseases. There is concern that high dietary intake of a maize-based diet may expose people in Mexico and Central America to fumonisins. Nixtamalized maize products from Mexico and the United States were examined to evaluate methods for quantitation of the different forms of fumonisins. The chelating reagent EDTA (exceeding the calcium concentration by a factor of 1.36) was added to enhance extraction of fumonisins because calcium remained in the samples as a result of processing. It was expected that the majority of the fumonisin detected would be in the hydrolyzed form, yet the highest level of hydrolyzed fumonisin B1 detected was 0.1 ppm. The amount of fumonisin B1 was significantly higher in Mexican samples (mean = 0.79 ppm) than in samples purchased in the United States (mean = 0.16 ppm).

AB:   The present research aimed to establish conditions for synchronized plantlet regeneration from rice callus based on a quantitative analysis of the relationship between intracellular 2,4-dichlorophenoxyacetic acid (2,4-D) concentration and shoot regeneration rate. To prepare the rice calli with different intracellular 2,4-D concentrations prior to regeneration, callus precultures were carried out in medium containing 4 mg/l 2,4-D and in 2,4-D-free medium for predetermined periods. As the critical intracellular 2,4-D concentration of the calli precultured in 2,4-D-free medium was too low to analyze precisely by conventional analytical methods, it was estimated using a kinetic model which described the behavior of 2,4-D by taking its uptake, metabolism and/or inactivation rates during the callus preculture into consideration. An experimental relationship between intracellular 2,4-D concentration and regeneration rate of rice calli revealed that the intracellular 2,4-D concentration should be controlled as low as 2.6 X 10(-2) microgram/g fresh weight to reach the same synchronization in shoot regeneration as seen with rice seed germination. This condition was realized by feeding sugar into the 2,4-D-free medium after 4 days preculture when the carbon source was exhausted.

AB:   The progenies of rice plants (Oryza sativa L.) differentiated from calli that had been cryopreserved and from control (non-cryopreserved) calli were used to study the influence of selection pressure during cryopreservation. The phenotypic evaluation of these progenies was based mainly on the response of seedlings and calli to freezing stress and on the characterization of protoplast and cell populations by flow cytometric analyses. The patterns of response to freezing stress, as well as the variations in some morphological and physiological cell parameters, were unrelated to the origin (cryopreserved or control calli) of the parental plants.

A high 2,4-D concentration (5-6 mg l-1) increased embryo production in genotypes of both species and promoted plant regeneration in anther cultures of A. sterilis and A. sativa X A. sterilis progeny, while kinetin caused severe browning. However, a low concentration of kinetin was essential for initiation of regenerable embryos from anther culture of A. sativa cv. Kolbu: one green and one albino plant were produced. In addition, medium containing W14 salts gave higher regenerant recovery compared with medium containing Murashge and Skoog salts, when cross progeny were tested.

AB:   The nitrite ion content and activity of nitrate reductase and nitrite reductase were examined in scutellum-derived calluses of rice varieties using a modified R2 medium (medium A) and a medium derived from the modified R2 medium (medium B). In medium A, marked differences were observed in callus growth between the varieties. The calluses of the poor-growth varieties accumulated significantly more nitrite ions during the culture period than did the good-growth varieties. Callus growth rate was negatively correlated with the nitrite ion content, indicating that the calluses of the poor-growth varieties were injured by toxic nitrite ions, which lead to browning and inhibited growth. The calluses of the poor-growth varieties had significantly lower levels of nitrite reductase activity than good-growth varieties. On the other hand, no between-group differences were observed in the nitrate reductase activity. These results indicate that the higher nitrite ion levels observed in the poor-growth varieties resulted from a lower ability to reduce nitrite and that nitrite reductase activity is one of the physiological factors that correlates with differences between varieties in rice cell cultures. In medium B, the calluses of the poor-growth varieties grew as well as the good-growth varieties, but also had significantly lower levels of nitrite reductase. Nitrate reductase activity was repressed in the calluses of both varieties in medium B compared to culture in medium A. The results suggest that repressed nitrate reductase activity causes the calluses of poor-growth varieties to accumulate only trace amounts of nitrite ions despite lower nitrite reductase activity and as a result, callus.
       growth improved in medium B.

AB:   Heterosis has helped to increase rice yield in F1 hybrids by 15-20% beyond the level of inbred semidwarf varieties. For stable yield performance rice hybrids must also possess genetic resistance to biotic stresses. One of these, stem borer, reduces the expected yield of hybrid rice. The truncated synthetic cryIA(b) gene from Bacillus thuringiensis is known to be effective in controlling stem borer. The development of transformation techniques has provided the technology for incorporating this bacterial gene into the rice genome, which has not been possible by conventional breeding methods. We have introduced a new approach of using a transgenic maintainer line for developing an insect-resistant hybrid rice. An elite IRRI maintainer line (IR68899B) has been transformed with the cryIA(b) gene driven by the 35S constitutive promoter using the biolistic method. The integration and expression of the cryIA(b) gene could be demonstrated through Southern and Western blot analyses that have been carried out so far up to the T2 generations. Insect bioassay data showed an enhanced resistance to yellow stem borer in the Bt+ transgenic plants. This is the first report of the development of a transgenic maintainer line for use in hybrid rice improvement.

AB:   The glass transition temperature of wheat gluten, plasticized with water, glycerol, or sorbitol, has been studied using dynamical mechanical thermal analysis. For the three plasticizers studied, the general behavior of the glass transition temperature broadly followed the Couchman-Karasz relation using a wheat gluten delta Cp of 0.4 J g-1 K-1. Compared on such a fractional weight basis, it could be concluded that the plasticizing effect of glycerol and sorbitol on wheat gluten proteins is less important than the plasticizing effect of water. A continuous curve was obtained with the three plasticizers when the evolution of the glass transition temperature was presented on a fractional molecular basis. This was related to the similar chemical structure of these three components containing hydroxyl groups.

AB:   To study a way to covalently link arabinoxylans and proteins using a fungal laccase from the fungus Pycnoporus cinnabarinus, the effect of cysteinyl caffeic acid on the cross-linking of wheat arabinoxylans was investigated by means of capillary viscometry and RP-HPLC of alkali labile phenolic compounds. Cysteinyl caffeic acid provoked a delay in gelation and in the consumption of the esterified ferulic acid on arabinoxylans. When reacting free ferulic acid and cysteinyl caffeic acid with laccase, the ferulic acid consumption and the dehydrodimers production were also diminished. These results suggest that cysteinyl caffeic acid is oxidized while reducing the semiquinones of ferulic acid produced by laccase. Thus, ferulic acid could not be oxidized into dimers until all cysteinyl caffeic acid was consumed, preventing the cross-linking of feruloylated arabinoxylan chains. A similar mechanism is proposed in the case of caffeic acid and of L-Dopa.

AB:   Rice bran protein isolate (RBPI) containing approximately 92.0% protein was prepared from unstabilized and defatted rice bran using phytase and xylanase. The yield of RBPI increased from 34% to 74.6% through the use of the enzymatic treatment. Nitrogen solubilities of RBPI were 53, 8, 62, 78, 82, and 80% at pHs 2.0, 4.0, 6.0, 8.0, 10.0, and 12.0, respectively. Differential scanning calorimetry showed that RBPI had denaturation temperature of 83.4 degrees C with low endotherm (0.96 J/g of protein). RBPI had similar foaming properties in comparison to egg white. But emulsifying properties of RBPI were significantly lower than those of bovine serum albumin. The result of amino acid analysis showed that RBPI had a similar profile of essential amino acid requirements for 2-5-year-old children in comparison to that of casein and soy protein isolate.

AB:   Chromosome 1D, which carries the advantageous alleles of glutenin and gliadin. attracts major interest with respect to improving the bread-making quality of triticale. Eighty-one BC1F4 lines from different primary and secondary hexaploid triticale crosses were selected for 1D chromatin analysis using SDS-PAGE and C-banding. In situ hybridization and RFLP-based comparative physical mapping of group 1 chromosomes revealed 20 lines with complete 1D (1A) substitutions. Nine 1D (1B) substitutions, six 1D (1R) substitutions and one 1D addition line were also selected. Three lines were pure AABBRR hexaploids without any D-genome chromosomes. For the remaining 42 lines (51.8%), a wide spectrum of 20 different recombinations between chromosomes 1A and 1D was uncovered. Altogether, they were generated without any earlier irradiation, tissue culture or genetic induction of chromosome pairing. In addition, 14 translocations between 1B/1D,1A/1R, 1B/1R, 1D/1R and 1A/1B were detected. Considerable variability for sedimentation values was found, with the highest sedimentation values among lines with complete 1D chromosomes. The implications of using triticale as a model for generating compensating chromosome rearrangements in defined homoeologous groups and the breeding potential of D-genome chromatin introgressed into triticale with improved sedimentation values are discussed.

AB:   Panicum maximum belongs to the agamic complex of the Maximae Panicoideae) which includes two other species, P. infestum Anders., P. trichocladum K. Schum., and several morphologically intermediate types. Andromonoecy and hermaphroditism have been recorded in this complex, but their distribution depends on the species, the level of ploidy, the mode of reproduction and the geographical origin. In particular, hermaphroditism appears to exist only in polyploid apomicts of the species P. maximum and was more frequent in maritime regions. Andromonoecy showed a monogenic and recessive inheritance. In andromonoecious plants, flowering of the male flower occurred later than that of the hermaphrodite flower within the spikelet. This flowering discrepancy varied between clones in respect of both mean and variance. All results are discussed in terms of the evolutionary process involved.

AB:   Crop germplasm collections contain a considerable percentage of misclassified accessions which may affect the use of germplasm for agricultural crop improvement. The objective of this study was to determine if random amplified polymorphic DNA (RAPD) analysis could be used to reclassify misclassified Triticum accessions. Twelve accessions suspected to be misclassified, based on morphological characters, as either macha or vavilovii wheat were studied using RAPD and cytological analyses. In the RAPD analysis, a dendrogram, based on Jaccard genetic similarity coefficients, grouped 5 dicoccum-like, 1 timopheevii-like, and 6 monococcum-like accessions with Triticum dicoccum, T. timopheevii, and T. monococcum accessions, respectively. These results were confirmed by the cytological analysis. A RAPD marker specific to the D genome was also detected. This study suggests that RAPD analysis can be used to classify germplasm and to distinguish some species in Triticum.

AB:   The complex Mla locus of barley determines resistance to the powdery mildew pathogen Erysiphe graminis f. sp. hordei. With a view towards gene isolation, a population consisting of 950 F2 individuals derived from a cross between the near-isogenic lines 'P01' (Mla1) and 'P10' (Mla12) was used to construct a high-resolution map of the Mla region. A fluorescence-based AFLP technique and bulked segregant analysis were applied to screen for polymorphic, tightly linked AFLP markers. Three AFLP markers were selected as suitable for a chromosome-landing strategy. One of these AFLP markers and a closely linked RFLP marker were converted into sequence-specific PCR markers. PCR-based screening of approximately 70000 yeast artificial chromosome (YAC) clones revealed three identical YACs harbouring the Mla locus. Terminal insert sequences were obtained using inverse PCR. The derived STS marker from the right YAC end-clone was mapped distal to the Mla locus.

AB:   The objective of this project was to conduct an aflatoxin proficiency test program in government, academia, and industry laboratories in Thailand. Aflatoxin-free corn and peanuts and corn and peanuts naturally contaminated with aflatoxins diluted to approximately 25 microgram/kg were analyzed. Homogeneity of prepared, naturally contaminated test samples was checked on multiple replicates. The test was conducted according to the ISO/IUPAC/AOAC INTERNATIONAL Harmonized Protocol with z scores indicating laboratory performance. The participants used 3 methods: enzyme-linked immunosorbent assay, thin-layer chromatography, and the minicolumn, of 19 laboratories that reported results for aflatoxins in naturally contaminated corn, 13 (68%) performed satisfactorily, on the basis of the mean obtained by an expert laboratory, a calculated target value for standard deviation, and the z score. Of 21 laboratories that reported results for aflatoxins in naturally contaminated peanuts, 10 (48%) performed satisfactorily. For aflatoxin-free corn, 6 laboratories reported finding atlatoxins at greater than or equal to 10 ng/g, chiefly by the minicolumn method; for aflatoxin-free peanuts, 1 laboratory reported finding aflatoxins at > 10 ng/g. Subsequently, a workshop of lectures and laboratory sessions was conducted to improve performance. A new and simple successive outlier removal procedure applied to the same data removed the same laboratories as did the use of z scores.

AB:   The deduced peptide sequences of 25 gene fragments of NBS-LRR resistance (R) gene homologues from rice and barley and of characterized R genes were compared, revealing a string of six conserved motifs. Mapping of the R-gene candidates in rice showed linkage to genes conferring race-specific resistance to rice blast (Pi-k, Pi-f and Pi-1) and bacterial blight disease (Xa-1, Xa-3 and Xa-4), in barley to powdery mildew (Mla) and the rust fungus (Rpg1). In rice four mixed clusters were detected, each harboring at least two highly dissimilar NBS-LRR genes. A YAC-contig was established for one of these mixed clusters. YAC fragmentation experiments revealed the presence of at least five NBS-LRR genes within 200 kb in head-to-tail orientation.

AB:   The inheritance of grain quality is more complicated than that of other agronomic traits in cereals due to epistasis, maternal and cytoplasmic effects, and the triploid nature of endosperm. In the present study, an established rice DH population derived from anther culture of an indica/japonica hybrid was used for genetic analysis of rice grain quality. A total of five parameters, amylose content (AC), alkali-spreading score (ASS), gel consistency (GC), percentage of grain with a white core (PGWC) and the square of the white core (SWC), were estimated for the DH lines and the parent varieties. For each parent, the value of each parameter was relatively stable in three locations, Beijing, Hangzhou and Chengdu, while the differences between the parents were significant for all five parameters. AC showed a bimodal distribution, and the distribution of ASS was skewed toward the value of JX17 while the other three parameters displayed continuous distributions among the DH lines with partially transgressive segregations. For AC, a minor and a major gene were found on chromosomes 5 and 6 respectively. The major gene, which should be an allele of wx explained 91.9% of the total variation. For GC, two QTLs were identified on chromosomes 2 and 7 respectively. For ASS, a minor and a major gene were both located on chromosome 6. The major gene should be the same locus as the alkali degeneration gene (alk). Genetic linkage between alk and wx was found in QTL mapping. For PGWC, two QTLs were located on chromosomes 8 and 12. Only a minor QTL was found for SWC on chromosome 3. The results and the molecular markers presented here may be useful in rice breeding for grain quality improvement.

AB:   Cell wall-bound invertase (CWI) is spatially and temporally the first enzyme which metabolizes the incoming sucrose in developing seed of maize (Zea mays). Our previous studies have shown that the cell wall-bound invertase-2 (INCW2) isozyme encoded by the wild-type gene of the Miniature1 (Mn1) seed locus plays a critical role in seed development. Null mutations of the gene, such as the mnl seed mutant which lacks invertase activity, are associated with a loss of approximately 70-80% of the normal seed weight. We show here that under in vitro kernel culture conditions the hexose-based medium was similar to the sucrose-based medium in promoting the normal development of kernels of the Mn1 but not of the mutant mn1 genotype. Anatomical, biochemical, and immunohistological data showed that the mn1 kernels retain their mutant phenotype regardless of the presence of sucrose or hexoses in the culture media. The most drastic changes in the mn1 seed mutant were associated with a significant reduction in the size of the endosperm, but not in the pattern or the level of starch localization. Because Mn1 expression was temporally coincident with the endosperm cell divisions, INCW2 must play a critical role in providing hexose sugars for mitotic division, and only a minor role in generating carbon skeletal substrates for starch biosynthesis in the early stages of endosperm development. Furthermore, a lack of the wild-type seed phenotype of the mn1 mutant in hexose media suggests that a metabolic release of hexoses catalyzed by INCW2, rather than an exogenous source, is critical for both generating appropriate sugar-sensing signals for gene expression and for normal endosperm development.

AB:   Chromosome 5A of wheat carries major gene loci for agronomic traits including the vernalization requirement (Vrn-A1) and ear morphology (Q). To determine whether the genetic variation for ear emergence time and plant height is attributable to either of these major genes as pleiotropic effects or independent QTL, we combined a RFLP map constructed from 120 recombinant substitution lines derived from a cross between 'Chinese Spring' (Cappelle-Desprez 5A) and CS (Triticum spelta 5A) with data collected from field trials over 3 years. For ear emergence time the main effects on flowering time were by Vrn-A1 and QEet.ocs-5A.1, the latter a QTL in the 28.6-cM Xcdo584/Q interval linked to Q by less than 10 cM. The CS (T. spelta 5A) allele at QEet.ocs-5A.1 contributed to an earlier ear emergence time by 2.7-6.0 days, which was approximately equal to the effects of Vrn-A1. For plant height, three QTLs were identified on the long arm and linked in repulsion. The CS (T. spelta 5A) allele at Vrn-A1 or closely linked to Xfba068 contributed to a height reduction of 3.5-6.1 cm, whereas both the Q allele and Qt.ocs-5A.1 allele within the Xcdo1088/Xbcd9 interval from CS (Cappelle-Desprez 5A) produced a shorter plant. When plant height was partitioned into culm length and ear length, the Vrn-A1 allele and CS (Cappelle-Desprez 5A) allele at QCl.ocs-5A.1 within the Xcd1088/Xbcd9 interval were found to contribute to a shorter culm. CS (T. spelta 5A) allele at q was a major determinant of a long ear, together with minor effects at QEl.ocs-5A.1 within the Xcdo1088/Xbcd9 interval.

AB:   Low-molecular-weight glutenin subunits (LMW-GSs) are wheat endosperm proteins mostly encoded by genes located at the Glu-3 loci. These proteins are of particular interest in durum wheat because a correlation between LMW-GSs encoded by genes at the Glu-B3 locus and the pasta-making quality of durum wheat semolina has been shown. We isolated and characterized two allelic lmw-gs genes located at the Glu-B3 locus and present in durum wheat lines displaying different qualitative properties. The clones pLMW1CL and lambdaLMW3.1 were found to contain allelic sequences encoding LMW-GSs belonging to the good and poor quality-related groups named LMW-2 and LMW-1, respectively. The LMW-GSs specified by these genes have very large repetitive domains which are composed of repeats regularly distributed along the domain. The main difference between these two proteins is an insertion of 13 amino acids within the repetitive domain which, by itself, seems insufficient to explain the qualitative differences between LMW-2 and LMW-1. These results further support the hypothesis that the greater amount of LMW-2, rather than sequence peculiarities, accounts for the better quality observed in durum wheat cultivars possessing these subunits. The characterization of the complete primary structure of these alleles, other than providing information for an understanding of the structure-function relationship among LMW-GSs and furnishing basic material for wheat engineering, should also assist in our understanding of the evolutionary relationship between the different lmw-gs genes.

AB:   RFLP, RAPD, STS and DDRT-PCR techniques were applied to find molecular markers linked to Pm13, an Aegilops longissima gene conferring resistance to powdery mildew in wheat. The experimental strategy was based on the differential comparison of DNAs from common wheat and from common wheat/Ae. longissima recombinant lines carrying short segments of the 3S'S chromosome arm containing the Pm13 gene. Sixteen RFLP clones that detect loci previously located in the short arms of group-3 wheat chromosomes were screened for their ability to hybridise to Ae. longissima restriction fragments derived from the 3S'S segments introgressed into the recombinant lines. Eight RFLP clones and one STS marker detected 3S'S-specific fragments whose location relative to the wheat-alien chromatin breakage point of the recombinant lines was determined. Four amplification products were identified through the screening of about 200 RAPD primers. Their polymorphism was associated with the introgression of the alien DNA. One of the differential fragments was derived from the 3S'S DNA segment, while the remaining three corresponded to the replaced 3DS DNA. Further analyses carried out using 40 combinations of DRT-PCR primers detected an additional reproducible polymorphism associated with the presence of 3S'S DNA. In view of their possible utilisation in Pm13 marker-assisted selection. differentially amplified RAPD and DDRT-PCR fragments were cloned, transformed into RFLP markers and converted into STS markers.

AB:   Genetic diversity in random amplified polymorphic DNAs(RAPDs) was studied in 110 genotypes of the tetraploid wild progenitor of wheat, Triticum dicoccoides, from 11 populations sampled in Israel and Turkey. Our results show high level of diversity of RAPD markers in wild wheat populations in Israel. The ten primers used in this study amplified 59 scorable RAPD loci of which 48 (81.4%) were polymorphic and 11 monomorphic. RAPD analysis was found to be highly effective in distinguishing genotypes of T. dicoccoides originating from diverse ecogeographical sites in Israel and Turkey, with 95.5% of the 100 genotypes correctly classified into sites of origin by discriminant analysis based on RAPD genotyping. However, interpopulation genetic distances showed no association with geographic distance between the population sites of origin, negating a simple isolation by distance model. Spatial autocorrelation of RAPD frequencies suggests that migration is not influential. Our present RAPD results are non-random and in agreement with the previously obtained allozyme patterns, although the genetic diversity values obtained with RAPDs are much higher than the allozyme values. Significant correlates of RAPD markers with various climatic and soil factors suggest that, as in the case of allozymes, natural selection causes adaptive RAPD ecogeographical differentiation. The results obtained suggest that RAPD markers are useful for the estimation of genetic diversity in wild material of T. dicoccoides and the identification of suitable parents for the development of mapping populations for the tagging of agronomically important traits derived from T. dicoccoides.

AB:   The albedo of land surfaces is strongly affected by transient surface conditions. For a vegetated surface, albedo can change with soil moisture, fractional canopy cover, and plant phenology as well as solar zenith angle (theta(s)). In this study, the relationships between albedo and plant phenology in prairie grassland and agricultural crops were examined by removing the effect of variations in theta(s). Albedos were evaluated at a constant theta(s), which was assigned to be 20 degrees in this study. For days with a minimum theta(s) larger than 20 degrees, a polynomial function that relates albedos to theta(s) was derived and applied to estimate the albedos at 20 degrees. After the removal of theta(s) variations, the observed albedos of grassland at the Konza Prairie showed a linearly decreasing trend from spring to winter due to prairie phenology. The observed albedo of a maize field showed a clear increase from seedling to peak green stage, except when drought caused a decrease in near-infrared reflectance. The observed albedos of a winter wheat field showed an uninterrupted decrease from peak green to harvesting stage.

AB:   Three different probes, obtained by PCR amplification and labelling of different segments of a PDI cDNA clone from common wheat, were used to identify and assign to wheat chromosomes the gene sequences coding for protein disulphide isomerase (PDI). One of these probes, containing the whole coding region except for a short segment coding for the C-terminal sequence, displayed defined and specific RFLP patterns. PDI gene sequences were consequently assigned to wheat chromosome arms 4BS, 4DS, 4AL and 1BS by Southern hybridisation of EcoRI- HindIII-and BamHI-digested total DNA of nulli-tetrasomic and di-telosomic lines of Chinese Spring. This probe was also employed for assessing the restriction fragment length polymorphism in several hexaploid and tetraploid cultivated wheats. These showed considerable conservation at PDI loci; in fact polymorphism was only observed for the chromosome 1B fragment.

AB:   The inheritance and expression of a transgene locus consisting of multiple copies of a rice chitinase gene under the control of the CaMV 35S promoter was studied in the T3 and T4 generations of a transformed line that expressed the chitinase at a high level. All T3 progeny of a homozygous T2 parent expressed the chitinase constitutively at 3 weeks after germination, but a proportion of the progeny had undetectable levels of chitinase 8 weeks after germination, indicating silencing of the transgene. Transgene silencing was also observed among progeny of a hemizygous parent. However, we did not observe chitinase gene silencing among progeny of another homozygous line that expressed the transgenic chitinase at a five- to tenfold lower level. Thus, expression level, rather than copy number, of the transgene appears to be critical for silencing. Silencing was observed in the leaf, sheath, and root tissues of the plant, indicating that it is not restricted to specific tissues. Silencing was first observed in the youngest leaves and only later in the oldest leaves of the same plant. There was co-silencing of the selectable marker gene, hpt, which is also driven by the CaMV 35S promoter. Unlike the two transgenes (chitinase and marker), the resident homologous chitinase gene with seed-specific expression and two nonhomologous chitinase genes induced in the leaves upon pathogen infection were not silenced. The silent phenotype was inherited in the T4 generation plants, while progeny of expressing plants exhibited silencing. The chitinase transgene appeared intact, and no evidence for gross alterations or methylation of CCGG sites was found. The silent phenotype could not be reversed by.
       treatment with 5-azacytidine. Northern blot analysis and nuclear run-on transcription studies indicated that silencing occurred at the transcriptional level. The implications of transgene silencing in genetic engineering of monocot plants for disease resistance are discussed.

AB:   Induced mutants in the barley cultivar Triumph have been screened for reduced dormancy. One line, which germinated readily 2 weeks after harvest, was classified as ABA-insensitive, since it could tolerate a ten-fold increase in ABA, compared to its parent, before germination was inhibited. This mutant, designated TL43, was genotypically similar to Triumph and phenotypically similar under Scottish growing conditions, except for a slightly reduced grain size. In Spain, it showed considerable reductions in both grain yield and plant height, suggesting that it was less widely adapted than its parent. Levels of alpha-amylase activity were increased at both sites. The mutant appeared to be different from those with ABA insensitivity or altered dormancy previously documented in either barley or Arabidopsis.

AB:   A wheat germ 55-kDa protein was isolated by affinity chromatography with Matrigel immobilized on agarose, followed by preparative gel electrophoresis. This Matrigel-binding protein designated as WG-55 had an amino-terminal amino acid sequence which is identical to that of a putative mature form of wheat storage protein Gbl 1. WG-55 reacted with concanavalin A, indicating its glycoprotein nature as expected from the amino acid sequence of Gbl 1. As expected, similarly, WG-55 exhibited RGD-dependent cell adhesion activity for murine carcinoma cells. These data suggest that WG-55 or mature Gbl 1 protein may play a role in plant cell adhesion.

AB:   We screened 93 lesion mimic mutants of rice for resistance to the blast fungus, Magnaporthe grisea, and found eight mutants that exhibited significant resistance to the fungus. We called these mutants cdr (cell death and resistance and further analyzed three of them. Two mutations, cdr1 and cdr2, were recessive and one, Cdr3, was dominant. Many small brownish lesions developed over the entire leaf of the mutants 20-50 days after sowing. TUNEL staining revealed that DNA fragmentation occurred in leaf blade cells of the homozygous Cdr3 mutants. Autofluorescence and callose deposition were visible in leaf cells of these three mutants. Activation of two defense-related genes, PBZ1 and PR1, was observed in the leaves of the mutants; high expression of PBZ1 was correlated with the lesion formation in the three mutants, whereas PR1 was constitutively expressed in the cdr2 and Cdr3 mutants irrespective of the lesion formation. Levels of momilactone A, a major phytoalexin of rice, in these mutants were increased approximately 100-400-fold relative to the wild-type levels. Suspension-cultured cells of the cdr1 and cdr2 but not Cdr3 produced higher levels of H2O2 than the wild type when treated with calyculin A, an inhibitor of protein phosphatase 1. These results suggest that biochemical lesions of cdr1 and cdr2 lie in the early signaling steps leading to activation of the NADPH oxidase and that type-1 protein phosphatase is operative in protein dephosphorylation involved in NADPH oxidase activation.

AB:   The proton-translocating NADH:ubiquinone oxidoreductase (respiratory complex I) consists of at least 32 subunits in higher plants, nine of which are mitochondrially encoded (NAD1-7, NAD4L, NAD9). Complex I (CI) has been analyzed from a mitochondrial mutant of maize, NCS2, that carries a deletion for the 3' end of the nad4 gene. Mitochondria from highly defective, near-homoplasmic mutant plants have only trace amounts of the normal complex I. Instead, a reduced amount of a smaller complex, which also exhibits NADH dehydrogenase activity, is detected on 'blue-native' polyacrylamide gels. Subunits of 76 kDa, 40 kDa and 55 kDa, as well as NAD7 and NAD9, have been identified in the subcomplex by their cross-reactivity with heterologous antisera. The corresponding subunits in Neurospora are localized in a 'peripheral arm' of CI, which is known to assemble independently of a 'membrane arm'. The maize NCS2 CI subcomplex is loosely bound to the membrane and is missing several subunits that could be membrane components. Thus, the mutant CI subcomplex may consist of a peripheral arm. A reduction in the steady-state levels of NAD7 and NAD9 in NCS2 mitochondria occurs despite normal rates of biosynthesis and there is a concomitant decrease of the nuclear encoded 76 kDa subunit. The reduction in CI-associated NADH dehydrogenase activity in the nad4-deficient NCS2 mutant mitochondria is not associated with a compensatory increase in the activities or amounts of the putative 'exogenous' NAD(P)H dehydrogenases that are found in plant mitochondria.

AB:   Victorin is a host-selective toxin produced by Cochliobolus victoriae, the causal agent of victoria blight of oats. Previously, victorin was shown to be bound specifically by two proteins of the mitochondrial glycine decarboxylase complex, at least one of which binds victorin only in toxin-sensitive genotypes in vivo. This enzyme complex is involved in the photorespiratory cycle and is inhibited by victorin, with an effective concentration for 50% inhibition of 81 pM. The photorespiratory cycle begins with ribulose-1,5-bisphosphate carboxylase/oxygenase (Rubisco), and victorin was found to induce a specific proteolytic cleavage of the Rubisco large subunit (LSU). Leaf slices incubated with victorin for 4 hr in the dark accumulated a form of the LSU that is cleaved after the 14th amino acid. This proteolytic cleavage was prevented by the protease inhibitors E-64 and calpeptin. Another primary symptom of victorin treatment is chlorophyll loss, which along with the specific LSU cleavage is suggestive of a victorin-induced, senescence-like response. DNA from victorin-treated leaf slices showed a pronounced laddering effect, which is typical of apoptosis. Calcium appeared to play a role in mediating the plant response to victorin because LaCl3 gave near-complete protection against victorin, preventing both leaf symptoms and LSU cleavage. The ethylene inhibitors aminooxyacetic acid and silver thiosulfate also gave significant protection against victorin-induced leaf symptoms and prevented LSU cleavage. The symptoms resulting from victorin treatment suggest that victorin causes premature senescence of leaves.

AB:   An unconventional band in the thermoluminescence glow curve of barley leaves at about +50 degrees C was examined. In contrast to bands usually observed around +50 degrees C, this band (designated as CL) is not related to photosynthetic electron transport in photosystem II. The appearance of the CL band (1) requires previous freezing of the sample, (2) is not influenced by light excitation and (3) depends on the presence of oxygen. In pure oxygen the glow curves for both leaves and chloroplast suspension exhibit three maxima at about +40 degrees C, +65 degrees C and +90 degrees C. Based on the emission spectra of the CL band and measurements with etiolated leaves, we suppose that the majority of emission corresponding to the CL band originates from chlorophyll. A lipoxygenase inhibitor, butylated hydroxytoluene, and sodium azide decrease the intensity of the CL band. We propose that the mechanism leading to emission of the CL band involves thermally stimulated production of an active oxygen species that results in lipid peroxidation.

AB:   Iron fortification could reduce the high prevalence of iron deficiency in countries where diets are cereal-based. The sensory quality and storage stability of iron-fortified maize were evaluated by descriptive analysis and hexanal production. Porridge was prepared from maize either unfortified or fortified with 30 or 60 mg iron/kg as ferrous sulfate, bisglycinate, trisglycinate, or NaFeEDTA, then stored at 30, 40 or 50 degrees C for 20 days. Fifteen judges, trained in descriptive analysis rated the intensity of 20 sensory attributes of 28 samples. Hexanal production was measured by static headspace gas chromatography. Bisglycinate produced the most rancidity. Iron fortification with bisglycinate lowered the sensory quality and storage stability of maize.

AB:   The influence of starch addition on the elastic properties of fish-meat gel was studied by measuring dynamic viscoelasticity, microscopic observation, and compression tests. Samples with pregelatinized starch, and with and without raw starch were studied. The temperature dependence varied according to the size of the starch granules. Starch granule-size/temperature dependence in the free swellable state was higher than in the fish-meat sol (surimi) protein in the heating process. Results indicated that raw starch affected the surimi protein network with a possible "packing effect" of starch granules, which increased the elastic modulus of the fish-meat gel.

AB:   Highly concentrated branched oligosaccharides (HBOS) were prepared from liquefied corn starch by a continuous process using an immobilized Bacillus licheniformis maltogenic amylase (BLMA) and yeast fermentation. Physicochemical properties of HBOS were evaluated and compared with those of sucrose and commercial oligosaccharides. An HBOS solution showed flow behavior nearly Newtonian. At relative humidities of 32% and 90%, HBOS exhibited high moisture retention and absorption properties. HBOS were relatively stable against heating at pH 3. Addition of 10-20% HBOS to starch increased its gelatinization temperature by 5-10 degrees C. The glass transition temperature of freeze-concentrated HBOS was higher than that of sucrose, suggesting the potential of HBOS for use in the storage of frozen foods.

AB:   The gel behavior of barley beta-glucan (BBG) gum extracted in our laboratory was compared to low-and high-viscosity commercial BBG gum and cornstarch using compression between parallel plates. Effects of beta-glucan concentration and hydration temperature on gel behavior were examined. BBG gum gelled at >(or)= 5% concentration and gel strength increased (p <(or)= 0.05), but not proportionally, with concentration. Hydration temperature did not influence gel strength. Commercial beta-glucan had higher (p <(or)= 0.05) gel strength than our BBG gum at 5% concentration. Cornstarch produced approximately 78% softer gel than BBG gum at 6% concentration. BBG may have potential as a gelling agent.

AB:   The polyphagous predator, Coleomegilla maculata (DeGeer) (Coleoptera: Coccinellidae), commonly oviposits on the native weed, Acalypha ostryaefolia Riddell (Euphorbiaceae), in and around Kentucky sweet corn fields. Cannibalism of eggs by C. maculata adults and larvae is drastically lower on A. ostryaefolia than on nearby sweet corn plants. We examined ovipositional preference of C. maculata for A. ostryaefolia plants or sweet corn plants, dispersal of larvae from A. ostryaefolia plants, capability for dispersal of larvae across bare soil (e.g., to nearby plants), ability of larvae to climb from ground level up A. ostryaefolia plants or sweet corn plants, and effect of A. ostryaefolia borders adjacent to sweet corn plots on C. maculata population density in sweet corn. The ovipositional preference study revealed that C. maculata laid more eggs on A. ostryaefolia than on corn. First-instar C. maculata that hatched from egg clusters on A. ostryaefolia dispersed predominantly by falling, rather than crawling, to the ground. Glandular trichomes on A. ostryaefolia petioles and stems apparently inhibited intraplant movement of first instars, resulting in those larvae falling directly from leaves to the ground. Some first instars were capable of moving at least 8 m across bare soil in 24 h. From the ground, significantly more first instars climbed sweet corn plants than climbed A. ostryaefolia plants. Significantly more larvae were present in sweet corn plots bordered by A. ostryaefolia plants than in sweet corn plots without an A. ostryaefolia border. These findings show that physical attributes of companion plants can significantly influence natural enemy populations on crop plants by affecting.
       interplant dispersal of natural enemies.

AB:   Probing behaviour of Aphis fabae Scopoli and Rhopalosiphum padi (L.) was tested in different stress situations normally occurring in aphid-plant studies such as interruption of feeding or starvation, transfer to a new plant, and attachment to the electrode wire. The DC electrical penetration graph (EPG) technique and a 'honeydew clock' were used to collect data on behavioural effects of these stress conditions. As a general effect, an interruption of feeding behaviour acted as a 'reset', i.e., the same sequence and time course of probing events were shown, irrespective the interruptions duration, from 1-100 min. Nevertheless, some minor differences were found, especially in A. fabae. Increased interruption times (deprivation from the host plant) stimulated the aphids to insert their stylets earlier. When A. fabae was put back on its host plant after a one min interruption phloem feeding started earlier than with longer interruption times, but only when it was put back to the same plant and feeding site on which it fed before. It is concluded that this effect is at least partly due to 'memory' of previous probing/feeding experience on the plant as it vanishes with longer interruption times. This explanation also holds for phloem salivation (E1) before starting sustained sap ingestion, which was reduced on the previous feeding site, but only after the one min interruption in A. fabae. The aphid-plant specificity appeared high in these effects. Both aphids were somewhat affected by wiring, resulting in earlier probing, longer total pathway phase, and less and later phloem feeding (as reflected by honeydew excretion). Thus confirming, that the evaluation of EPG results can.
       be improved with supplementary data from free aphids.

AB:   The virulence of Nilaparvata lugens Stal (Homoptera: Delphacidae) to a resistant variety of rice, Oryza sativa L., is suggested to be under polygenic control. To determine whether the virulence of N. lugens is a quantitative character that has continuous distribution or a threshold character that has a few discontinuous phenotypic forms and is determined by some underlying continuous variable, I examined the frequency distribution of honeydew excretion that has been used as a measure of ability of attacking the rice plants, and the relationship between honeydew excretion and the oviposition rate of N. lugens females using a japonica rice line Saikai 190 which has a resistance gene Bph 1. The frequency distribution in honeydew excretion significantly differed from the normal distribution, but two distributions below and above 10 mg honeydew excretion for two days did not significantly deviate from normality, suggesting a bimodal distribution. There were significant differences in the proportion of females ovipositing and the number of eggs deposited between the female groups that excreted 0-10 mg honeydew and more than 20 mg honeydew. Within these female groups, however, the reproductive performances were not different. Thus, virulence of N. lugens can be analyzed as a threshold character that has two distinct phenotypes, virulent and avirulent. I estimated the heritabilities of the virulence of N. lugens by parent-offspring regression using the percentage of virulent females in a full-sib family. The estimates of heritability were 0.41 on Saikai 190 and 0.55 on ASD7, carrying the bph 2 gene. These results show that the N. lugens population has substantial genetic variation in.
       virulence. The regression coefficients on female and male parents were similar, suggesting similar genetic contributions by both parents. When the parental families were examined on Saikai 190 and the progeny on ASD7, the regression coefficient approached zero. There may be a low genetic correlation between virulences to the two varieties.

AB:   The present study examined the acceptability and suitability of Old World stemborers (Chilo partellus and C. orichalcociliellus) for the development of New World parasitoids (Apanteles deplanatus and A. minator) and New World stemborers (Diatraea saccharalis and D. grandiosella) for the development of Old World parasitoids (Cotesia sesamiae, C. flavipes and C. chilonis). Results revealed that acceptance and suitability were high in old associations. In new associations, parasitoids accepted about 60% of the new association hosts. In addition, 10 out of 17 new associations were successful. Apanteles species appeared to be more physiologically host specific than Cotesia species. For example, two of four new association hosts were accepted by A. deplanatus and only one (D. saccharalis) was partially suitable for progeny development. Among the Cotesia species, Cotesia flavipes appeared to have a wider host range than the two other species. It attacked all hosts offered and successfully parasitized all but one (D. grandiosella). Diatraea saccharalis was accepted and was a suitable host for the development of all parasitoid species tested, whereas D. grandiosella was unsuitable for the development of four out of five parasitoid species tested. No clear pattern was observed as behavioral acceptance did not always agree with the pattern of physiological suitability. Implications of these findings for importation biological control of stemborers are discussed.

Addition of soy protein increased the temperature and pressure while decreasing motor torque. Results of two consumer tests for 12 prototype products and the most acceptable three samples indicated positive responses. Acceptance correlated highly with consumer attitudes toward soy foods and prior information about health effects of soy protein. Differences between protein types suggested that formulation optimization could develop highly acceptable soy/corn extruded snacks.

AB:   Differential scanning calorimetry (DSC) was used to measure apparent specific heat and heat of gelatinization for corn starch at a 13.4 to 79.1% moisture and 30 degrees C to 100 degrees C. Apparent specific heat of granular and heated starch was determined as a function of moisture content, temperature, and gelatinization. Effect of gelatinization was maximum at 42.3% moisture (wet basis) where the ratio of starch/water caused the largest differences in apparent specific heats. The largest difference corresponded to a degree of gelatinization of 0.429. A model was developed to predict apparent specific heats and provided values with a +/-2.57% standard error (compared to experimental values) for heated starch with partial gelatinization over the range from 13.4 to 79.1% moisture.

AB:   DSC (Differential Scanning Calorimetry) peak temperature of starch was decreased by adding zein, but was increased by adding guar gum. Adding zein increased the initial rate of starch cooking, but adding guar gum decreased it. Kinetic studies were carried out at 115, 125, and 135 degrees C. At 25 degrees C, zein absorbed less water than waxy corn starch, especially at water activities >0.6 where guar gum absorbed more water than starch. The strong binding of water by guar gum increased DSC-peak-temperature and decreased the initial rate of starch cooking. The relatively weak binding of water by zein decreased DSC peak temperature and increased the initial rate of starch cooking. Although water sorption data at cooking temperatures are difficult to measure, the kinetic data at these temperatures and DSC data could be used to supplement the sorption data.

AB:   Extruded instant corn flour (EICF) samples with hydrocolloids (gums), such as gum arabic, carboxymethylcellulose (CMC), guar and xanthan and with different concentrations of lime (0.1, 0.2 and 0.3% w/w) were prepared by extrusion. The gums were added before or after thermal processing. The dehydration process followed through the weight loss (WL) in masa, the physicochemical (water absorption capacity (WAC) and WL during cooking) characteristics of masa were optimized to give longer dehydration times and tortillas with good textural (rollability, tensile strength and cutting force) properties. The lowest effective moisture diffusion coefficient (D*) was found in masa samples containing 0.2% (w/w) of lime and 0.5% (w/w) of the xanthan gum added before extrusion. These masas produce tortillas with optimum textural characteristics and highest yields.

AB:   The effect of heating film-forming solutions on physical and molecular properties of cast wheat gluten (WG) films was determined. Glycerol-plasticized films were cast from alkaline (pH 10), heat-treated (55, 75, or 95 degrees C for 10 min) solutions of WG in aqueous ethanol. Protein solubility (PS) of films in water decreased (P<0.05) with increasing temperature. Gel permeation chromatograms showed reduced extractability of protein fractions other than omega-gliadins in WG films. This reduced extractability was due to disulfide (S-S) bond formation. SDS-PAGE patterns of native WG and WG film samples suggested increased cross-linking through covalent S-S bonds in films from solutions heated at 75 or 95 degrees C. Water resistance in potential packaging applications of WG edible films could be modified by adjusting heat-treating temperature.

Using a specially designed holder, high quality images of cooked rice grains were obtained, even when up to 10 grains were studied simultaneously. Internal hollows were observed. In all examined cooked rice grains and we propose a mechanism to explain their formation. The origin of these hollows was hypothesized to be cracks or fissures, and hollows from sealing of such lacerations by gelatinized starch In the peripheral layer. In combination with expansion of the grain during cooking.

AB:   Cytokinins are degraded by cytokinin oxidases (CKOs) which catalyse cleavage of the N6-(isopent-2-enyl)-side chain resulting in formation of adenine-type compounds. CKO activity has been recorded in many plants and is thought to play a key role in controlling cytokinin levels in plants. Several partially purified CKOs have been characterised but no genes have been isolated yet. CKO activity is known to be inhibited by phenylureas, cytokinin agonists. We used 1-(2-azido-6-chloropyrid-4-yl)-3-(4-[3H])phenylurea ([3H]-azidoCPPU) to photolabel a glycosylated CKO from maize kernels. This enabled us to purify the enzyme. Peptide sequences were determined and the corresponding cDNA was cloned. The deduced amino acid sequence shares homology domains with FAD-dependent oxidases. An original assay based on transient expression of the enzyme in moss protoplasts allowed the functionality of the recombinant enzyme to be demonstrated.

AB:   The characterization of plasmid-genomic DNA junctions following plant transformation has established links between DNA double-strand break repair (DSBR), illegitimate recombination and plasmid DNA integration. The limited information on plasmid-plasmid junctions in plants comes from the dicot species tobacco and Arabidopsis. We analyzed 12 representative transgenic rice lines, carrying a range of transforming plasmid rearrangements, which predominantly reflected microhomology mediated illegitimate recombination involving short complementary patches at the recombining ends. Direct end-ligation, in the absence of homology between the recombining molecules, occurred only rarely. Filler DNA was found at some of the junctions. Short, purine-rich tracts were present, either at the junction site or in the immediate flanking regions. Putative DNA topoisomerase I binding sites were clustered around the junctions. Although different regions of the transforming plasmid were involved in plasmid-plasmid recombination, we showed that a 19 bp palindromic sequence, including the TATA box of the CaMV 35S promoter, acted as a recombination hotspot. The purine-rich half of the palindromic sequence was specifically involved at the recombination junctions. This recombination hotspot is located within the 'highly recombinogenic' region of the full-length CaMV RNA that has been shown to promote viral recombination in dicot plants. Clustering of plasmid recombination events in this highly recombinogenic region, even in the absence of viral enzymes and other cis-acting elements proves that the plant cellular machinery alone is sufficient to recognize and act on these viral sequences. Our data.
       also show the similarity between mechanisms underlying junction formation in dicot and monocot plants transformed using different procedures.

AB:   Cannibalism is well known to affect both the population dynamics and the competitive relationships of organisms. Cannibalistic behaviour commonly increases in stressful conditions, such as when density is high or food is scarce, and cannibals often obtain a nutritional benefit. Might cannibalism also increase in a novel environment to which a population is poorly adapted physiologically? Moreover, might cannibalistic behaviour provide enough of a nutritional advantage in a nutritionally stressful environment to rescue individuals from its adverse effects and thus permit colonization and range expansion? Previous work has shown that oat flour is a particularly stressful environment for Tribolium castaneum. In the study reported here, egg cannibalism by two strains of T. castaneum was significantly enhanced in oat flour, and egg eating rescued larvae from the adverse demographic effects of this poor environment. Development time of the cannibals was accelerated almost to the level seen for individuals reared in the nutritionally superior environment (wheat plus brewer's yeast). Their survival and fecundity also increased relative to individuals reared in oat flour without the opportunity to cannibalize. A sib analysis revealed that for larvae reared in the presence of victim eggs, the extent of cannibalism was genetically variable, so that this trait could evolve, given a selective benefit exceeding its cost. These results suggest that colonization of a marginal new environment could be facilitated by enhanced rates of cannibalism. The possible interplay between cannibalism and physiological adaptation to a new environment is discussed.

AB:   Near identical trials conducted concurrently in maize plots in Honduras and Mexico produced similar results in the pattern of larval mortality of Spodoptera frugiperda following application of a baculovirus or a conventional synthetic insecticide. The highest application rates of virus resulted in approximately 40% mortality of S. frugiperda larvae. Virus-induced mortality decreased with time. Parasitism by wasps and tachinids also contributed up to 40% mortality in field-collected larvae. The application of chlorpyrifos resulted in a resurgence of S. frugiperda. Chlorpyrifos also reduced a number of important predators in the maize crop which is likely to have been influential in the observed resurgence of this pest. The use of granulated sugar in the viral formulation caused an increase in the population density of several maize-associated insect species, and in Mexico a transient increase in parasitism was observed in sugar-treated plots. Sugar did not appear to increase the probability of infection by acting as a feeding stimulant in either trial. A preliminary analysis of the cost of viral production and application indicates that virus was considerably more costly than conventional control. To be commercially viable, economics of scale both in the cost of material for the insect diet and in the efficiency of manpower-related activities are needed to substantially reduce the costs of the viral product. Despite high levels of infestation by S. frugiperda, grain weight/cob was not significantly improved by the application of the biological or synthetic insecticide. Natural mortality factors both biotic and abiotic appear to have a large impact on larval S.
       frugiperda populations. For improvements in yield, the impact of control measures against S. frugiperda may be dependent on plant growth stage. Trials on timing and frequency of virus application are in progress to test this idea.

AB:   Double-cropping provides a method of diversifying the rotation, maximizing production, and increasing the profit potential of a cropping system. We assessed agronomic and economic performance of five alternative crops in comparison to the no-till wheat-soybean double-cropping system prevalent in the southern Corn Belt. Canola has shown potential as a profitable winter crop, but its effects on the subsequent crop in a no-till double-crop system required further study. Amaranth, buckwheat, sunflower, and pearl millet were planted after the harvest of canola or wheat, or after fallow. Alternative double-crop grain yield, production costs, and net returns were compared with those of double-crop soybean. Wheat yielded more than canola. Sunflower grain yields did not differ significantly after winter-crop treatments at any site. Yields of amaranth, buckwheat, soybean, and pearl millet differed after winter crops at some sites. At three study yield levels, net returns were positive and greatest for double-crop wheat-amaranth, canola-amaranth, wheat-sunflower, and canola-sunflower systems. All double-crop systems except canola pearl millet had positive net returns at median study yield levels. Low or negative net returns resulted from the combination of low yield and low price for some double crops. Canola was shown to be an economically feasible alternative to wheat in a double-cropping system for central and southern Missouri. Buckwheat and sunflower were shown to be agronomically and economically competitive alternatives to soybean following either canola or winter wheat, with buckwheat most valuable in late-season planting conditions.

AB:   Nitrate contamination of surface water resulting from inputs of agricultural drainage water is a widespread problem. To learn whether alternative agricultural practices might ameliorate this problem, we measured NO3(-) in water draining from three neighboring fields from 1970 to 1992. Drainage water from two fields fertilized with N exclusively as composted and liquid manure had NO3(-) concentrations less than 2 ppm (20% of the Public Health Service recommended limit for drinking water). When these fields were converted to a corn/soybean rotation fertilized with anhydrous ammonia, NO3(-) concentration increased about 7- to 10-fold. On a third field, corn was always fertilized with anhydrous ammonia. Changing this field from a rotation of corn, oats and hay to corn/soybean and increasing the rate of N fertilization by about 18% almost doubled the NO3(-) concentration in the drainage water. The corn/soybean rotation most prevalent in the Corn Belt today resulted in high NO3(-) concentrations in the drainage water, while the alternative system prevented NO3(-) problems.

AB:   The interactive effects of ozone and light on leaf structure, carbon dioxide uptake and short-term carbon allocation of sugar maple (Acer saccharum Marsh.) seedlings were examined using gas exchange measurements and 14C-macroautoradiographic techniques. Two-year-old sugar maple seedlings were fumigated from budbreak for 5 months with ambient or 3 x ambient ozone in open-top chambers, receiving either 35% (high light) or 15% (low light) of full sunlight. Ozone accelerated leaf senescence, and reduced net photosynthesis. 14CO2 uptake and stomatal conductance, with the effects being most pronounced under low light. The proportion of intercellular space increased in leaves of seedlings grown under elevated ozone and low light, possibly enhancing the susceptibility of mesophyll cells to ozone by increasing the cumulative dose per mesophyll cell. Indeed, damage to spongy mesophyll cells in the elevated ozone x low light treatment was especially frequent. 14C macroautoradioraphy revealed heterogeneous uptake of 14CO2 in well defined areole regions, suggesting patchy stomatal behaviour in all treatments. However, in seedlings grown under elevated ozone and low light, the highest 14CO2 uptake occurred along larger veins, while interveinal regions exhibited little or no uptake. Although visible symptoms of ozone injury were not apparent in these seedlings, the cellular damage, reduced photosynthetic rates and reduced whole-leaf chlorophyll levels corroborate the visual scaling of whole-plant senescence, suggesting that the ozone x low light treatment accelerated senescence or senescence-like injury in sugar maple.

AB:   Tissue flow measurements of leaf material in Lolium perenne (perennial ryegrass), Agrostis capillaris of Poa annua, and Trifolium repens (white clover) were made at three upland sites in Scotland (Hartwood, Sourhope and Fasque) in 1992/93 to determine if there were differences in seasonal growth, senescence and losses to herbivory between species in their response to more extensive sward management. The measurements were made monthly from May until October in established predominantly perennial ryegrass/white clover swards receiving three different treatments. One treatment received a conventional annual fertilizer application of 140 kg N/ha plus maintenance P and K and was grazed by sheep at a sward height of 4 cm (4F), whereas the other two treatments were unfertilized and grazed to maintain a sward height of 4 cm (4U) or 8 cm (8U). Significant sources of the variation in leaf appearance, increase in green lamina/petiole length (leaf extension), senescence and losses to herbivory were attributable to site, sward, species and date of measurement. The rate of leaf extension for all three measured species was less in 4U than 4F swards, and less in 4U than 8U swards.  Leaf extension of L. perenne exceeded that of the other species, even in unfertilized swards but rates of leaf appearance were less. There was some evidence in spring of a reduction in net growth as a consequence of removing fertilizer inputs and maintaining a sward height of 4 cm. Species differences in the losses of leaf tissue to herbivory were dependent on sward management. In the 4F treatment, leaf loss to herbivory from L. perenne tillers was greater that from either A. capillaris, P. annua or T. repens in May, June and.
       September. In the 4U treatment more leaf tissue was also lost from L. perenne than from T. repens. In contrast, there was no difference between grass species in losses to herbivory in either unfertilized sward. The responses of species to changes in fertilizer and grazing management were similar at three sites of differing fertility. The results are discussed in relation to plant competition and species dynamics in extensively managed swards.

AB:   The interaction between headbugs (Eurystylus sp.) and grain mould (GM) on sorghum was examined in field trials carried out at Samaru, Nigeria in the 1995 and 1996 wet seasons. The results obtained show that in all three sorghum cultivars tested, insect damage increased the number of fungal colonies associated with the grain. This resulted in lower germination, 1000-grain mass and yield in such treatments. Insect damage also altered the relative abundance of the common fungal flora species as, following insect damage, Fusarium moniliforme (= Gibberella fujikuroi), Phoma sorghina and Curvularia lunata (= Cochliobolus lunatus) were the most common fungi in decreasing order of frequency as against the normal order of P. sorghina, F. moniliforme followed by C. lunata. These results are the first clear evidence of interactions between headbugs and GM in Nigeria.

AB:   Cowpea and sorghum grain crops, fertilized with 26 kg of phosphorus (P) per ha from either a P-soluble (SP) or a slightly P-soluble fertilizer (Kodjari, a natural rock phosphate (RP) indigenous to Burkina Faso), and cowpea and crotalaria (Crotalaria retusa) green manure crops, either unfertilized or fertilized with 26 kg P/ha from RP; were studied for their effects as preceding crop treatments for maize. The experiment was conducted in semi-arid West Africa (SAWA) at Farako-Ba in Burkina Faso in 1983-86. Nitrogen (N) and soluble P fertilized and unfertilized subtreatments in improving soil fertility and the direct effects of P and N fertilizers applied to the maize crop to be assessed. Maize productivity was increased both by P fertilization and by soil improvements following cowpea and crotalaria; N fertilization in excess of 60 kg N/ha was not beneficial. Cowpea grain crop treatments, especially when fertilized with a P-soluble source, maximized maize yields, whereas cowpea and crotalaria green manure treatments were either similar to the cowpea grain treatment fertilized with RP or were intermediate between the latter and the sorghum treatment fertilized with SP. Sorghum, regardless of the source of P-fertilizer used, appeared not to be a suitable preceding crop for maize in SAWA.

AB:   A natural rock phosphate, 'Kodjari' (RP), sparingly soluble, indigenous to Burkina Faso, and a commercial single superphosphate (SSP) fertilizer were studied at Farako-Ba in the Northern Guinea Savannah (NGS) and at Oipasse in the Sudan Savannah (SS) regions of Burkina Faso. A 3-year crop sequence either of cowpea, maize and sorghum or of cowpea, sorghum and sorghum was used, respectively, in the NGS and SS regions. The sorghum crop in the third year was not fertilized with any phosphorous (P) source. The objectives of the research were to study the direct and residual effects of the P fertilizers on soil fertility improvement in order to boost agricultural productivity in both regions. Cowpea daylength-insensitive cultivars, in both regions, and maize and sorghum in the NGS and SS regions, respectively, responded more strongly to SSP than to RP fertilizer treatments. The optimum rate of SSP and RP source was 21.8 kg P/ha and 43.6 kg P/ha, respectively, for cowpea in both regions. The optimum rates of phosphorus fertilizer applied in the second year to maize in the NGS and to sorghum in the SS region, in addition to the optimum rate of P applied to cowpea the previous year, was 10.9 kg P/ha of SSP or 43.6 kg P/ha of RP, and 21.8 kg P/ha of SSP or 43.6 kg P/ha, respectively. Both P sources had significant residual effects for up to 2 years. The agronomic effectiveness of RP relative to SSP, in the year of application of both fertilizers, was greater for cowpea than for maize in the NGS region and similar for cowpea and sorghum in the SS region; it increased markedly for the two subsequent cereal crops in both regions.

AB:   The productivity of eight forage maize cultivars (Zea mays L.) in response to N was investigated in a 3-year field experiment located in Northern Germany. Nitrogen fertilizer applications were zero, 50 and 150 kg N/ha given each year shortly after sowing. Each cultivar was grown on the same plot, beginning in 1993, following the ploughing up a 2-year old grass sward, to which slurry had been added. Plants were sampled regularly for dry matter (DM) production and N uptake. A non-linear regression equation was used to compare the data. Growth analysis and N uptake characteristics (maximum crop growth rate, duration of maximum crop growth rate, period until maximum crop growth rate, maximum N uptake rate, duration of maximum N uptake rate, period until maximum N uptake rate) which derived from the function were used to compare the cultivars. The cultivars DM yield and N uptake were highest in 1993 and declined in the next two years partly due to a decrease in soil N mineralization following the ploughing of the grass sward and partly due to the drier weather conditions during the summers of 1994 and 1995. Duration of the maximum crop growth rate was greater during the cool year of 1993. In contrast, maximum crop growth rate was at its highest in the dry vegetation period of 1995. A significant N x cultivar interaction for growth analysis characteristics (P < 0.05) was found in 1995. Cultivars with a high maximum crop growth rate (above the average value of the eight cultivars tested) and a short duration of maximum crop growth rate (below the average) accumulated more DM than those genotypes which showed an inverse relationship. Increasing N yield was determined by increased maximum N uptake rather.
       than by a greater duration of maximum N uptake. A significant N x genotype interaction for N uptake parameters (P < 0.05) was found in 1994 and 1995. With some exceptions, cultivars with a high maximum N uptake rate (above average) accumulated more N per unit area compared to those genotypes which had low uptake rates. The exceptions had a longer duration of uptake, which could not, however, compensate for the lower rate. Maximum N uptake rate occurred earlier and duration of maximum N uptake rate increased compared to the start and duration of maximum crop growth rate. Especially in 1995, the amount of N taken up before the day of maximum crop growth rate accounted for 71% of total N uptake. The N uptake rate and the amount of accumulated N until the day of maximum crop growth rate were highly correlated with DM yield. This result indicates the availability of genotypic variability in crop growth and N uptake rate to assist the improvement of DM yield by selection.

AB:   Three pot experiments were performed at the University of Wales, Bangor, Gwynedd, UK during 1993 to determine if differences in the competitive ability of three annual weeds (Chenopodium album L., Sinapis arvensis L. and Phalaris minor Retz.) were related to their relative effects on leaf growth, gas exchange and nitrogen uptake of spring wheat (cv. Alexandria). In all experiments, wheat density (316 plants m-2) was similar to that in a commercial crop and five weed density treatments (between 0 and 600 plants m-2) were tested. Measurements of gas exchange were made on fully expanded, attached wheat flag leaves on four occasions between emergence and complete senescence in the control and highest weed density treatments. High weed density resulted in a lowering of net photosynthetic rate due to stomatal and non-stomatal factors. Lamina area and stomatal density of wheat flag leaves were decreased, and specific leaf area was increased by weed competition, but the effects on these variables were smaller than on net photosynthesis. Weed density did not affect wheat plant height, but dry weight, grain yield and total N-uptake were decreased with an increase in density of all weed species. The rank order of competitive ability of the species (C. album > P. minor > S. arvensis) was unaffected by weed density and was the same irrespective of whether it was based on the percent decreases in wheat grain yield or in total plant dry weight. Averaged over the four measurements made during the grain-filling period there were only small differences between the weed species in their effects on net phosynthetis rate. However, when these were combined with effects on flag leaf area, there were larger differences in.
       calculated net photosynthetic productivity, which were related to differences in effects of weeds on grain yield. Differences in the competitive ability of weeds were not related to differences in their effects on wheat flag leaf lamina area, specific leaf area, stomatal density or total nitrogen uptake. Differences in competitive ability between weed species were not related to differences in weed plant height, dry weight or nitrogen uptake. It was concluded that the observed effects of weeds of wheat were due to shading, or to competition for a nutrient other than nitrogen.

AB:   The effects of weather and nitrogen application rate on bread volume, protein concentration and gluten strength were investigated in spring and winter wheats in Sweden during 1990-96. The investigation was carried out in wheats containing the high-molecular-weight (HMW) glutenin subunit combinations 2 + 12 or 5 + 10. The results showed that a warm (c. 20 degrees C mean dry temperature) and dry grain-filling period, as during 1994 and 1995, led to high gluten strength. As a relatively gentle dough mixing is normally applied in Sweden when baking bread, excessively high gluten strength results in low bread volumes. Wheat cultivars containing HMW glutenin subunits 5 + 10 generally had higher gluten strength than those containing subunits 2 + 12. However, not all cultivars containing subunits 5 + 10 showed overstrong gluten properties, whereas some cultivars containing subunits 2 + 12 were overstrong during 1994 and 1995. Different cultivars produced the highest gluten strength in different years. Generally, cultivars containing HMW subunits 2 + 12 gave higher bread volumes than those containing subunits 5 + 10. This is probably due to the Swedish baking method, where the dough is given a relatively gentle mixing for a fixed period of time. Increased fertilizer rates led to increased protein concentration and decreased gluten strength. However, during certain years, for example 1994, the gluten strength was only decreased slightly by increased fertilizer rates, particularly in cultivars containing HMW glutenin subunits 5 + 10.

AB:   The recovery of nitrogen 'retained' through cover crop uptake, delayed ploughing and immobilization by straw was assessed in a spring cropping rotation on a chalk loam in Eastern England (1989-96). The effect of annual cover cropping on yield of the subsequent spring crops and on the soil N balance was also investigated. The recovery of retained N was in part dependent upon cover crop management. Late August-sown cover crops which were incorporated in February/March tended to reduce spring crop yields and crop N offtake. Adverse effects on soil N supply, seedbed conditions and soil water reserves were not in evidence and so an allelopathic effect from the decomposition of the rye cover crop, previously reported by others, may be responsible for the reduction in yield of spring crops. When the cover crops were drilled later and their early destruction was followed by a short fallow period, spring crop yields and N offtake were increased. The soil N balance indicated that over the course of the experiment there was a positive N input to the system due to continuous cover cropping. This input may be held as immobilized organic N, in which case it could be made available to subsequent crops over a number of years or lost via other routes. Nitrate concentrations in drainage water increased with the number of years under cover cropping.

AB:   A procedure for the non-radioactive detection of random amplified polymorphic DNA (RAPD) was developed and designated as digoxigenin (DIG)-based RAPD. Using this procedure, we analyzed somaclonal variation in cultured cells of rice. Somaclonal variation was found to increase with culture age. More than 50 polymorphic fragments were identified with the four primers tested. Random sequencing of 10 clones generated one intron, one 5'-noncoding, and eight non-redundant expressed sequences. A database search for homology showed that the eight exon sequences displayed a significant similarity to sequences already stored in EMBL, GenBank and DDBJ. The sources of the known genes ranged from microorganism to human, including three rice genes. The results showed that somaclonal variation might have occurred in transfer RNA, ribosomal protein, and other genes during cell culture.

AB:   Microprojectile-mediated transient and integrative transformation frequencies in rice (Oryza sativa cv. Taipei 309) embryogenic suspension cells were studied as a function of various parameters. Mannitol at concentrations of 0.5 and 0.6 M was best for osmotic preconditioning of the cells for transient, but not for integrative transformation, for which sucrose yielded the best and most reliable results. Denaturation of the transforming plasmid DNA prior to bombardment improved transient and integrative transformation frequencies two to three fold. Delivery of double-stranded plasmids in linear form had no effect on transient transformation when compared to super-coiled plasmid DNA, but led to an overall two fold increase in integrative transformation frequency. This shows that optimized protocols for generating transgenic plants should not be based exclusively on transient gene expression assays.

AB:   Plant lipid transfer proteins (LTPs) are thought to participate in many aspects of cell growth and development. We have identified a novel LTP gene (LTP-ne) from barley (Hordeum vulgare) through differential screening of an ovary cDNA library. LTP-ne was mapped to the distal region of the long arm of barley chromosome 4, distinct from the genomic location of other known LTPs. Sequence comparison indicated that LTP-ne was more closely related to the 7-kDa LTPs than to the 9-kDa LTPs in barley. In Northern hybridization, LTP-ne transcripts were detected in ovary, but not in other tissues, and were most abundant 3-4 days after pollination. Furthermore, RNA in situ hybridization showed that within the ovary. the LTP-ne gene was specifically expressed in the outer cell layer of the nucellus. These results showed that the newly identified barley LTP was ovular cell specific and regulated by pollination/fertilization.

AB:   The aim of these studies was to develop a semi-selective medium of differentiate Microdochium oryzae and Pinatubo oryzae, determine the frequency of seed infection of M. oryzae, study survival of the pathogen in stored seed, and determine the frequency of infection of seed components. To simulate epidemics of differing intensities, panicles of rice cultivars that are susceptible (IR36) and resistant (IR42 and IR46) to M. oryzae were either non-inoculated, inoculated once, twice, or three times with a conidial suspension of M. oryzae. Both M. oryzae and P. oryzae colonies were recovered from seeds and were similar in culture. A semi-selective medium developed to detect M. oryzae seed infection rates aided in differentiating M. oryzae and P. oryzae by simulating aerial conidiogenesis of P. oryzae. The conclusions taken from these results were: (a) seeds of IR36 had higher infection of M. oryzea than of IR42 and IR46 from plants grown in the dry season, but had lower infection of M. oryzae than of IR42 and IR46 from plants grown in the wet season; (b) M. oryzae infected seeds increased with an increase in the epidemic intensity with the highest occurring after three inoculations, the least occurring with non-inoculation, and intermediate with one, or two inoculations; (c) survival of M. oryzae decreased overtime in seed lots stored at 10 degrees C and 40 percent relative humidity and (d) all components of the rice seeds of IR36, IR42 and IR46 lots were infected with M. oryzae with the highest frequency in the endosperm and lemma, intermediate in the basal glumes and palea, and the least in the embryo.

AB:   The influence of enhanced UV-B radiation (approximately a 15% ozone layer reduction) on competitive interaction between spring wheat (Triticum aestivum) and wild oat (Avena fatua) was examined in the field. The density dependent mortality of both wheat and wild oat did not exhibit a significant difference between control and UV-B treatment conditions. A relatively high degree of competitive stress enhanced the effects of UV-B stress on biomass reduction. The relative competitive status of wheat in terms of total biomass increased under UV-B enhancement while it decreased when based upon grain production. Shifts in competitive balance occurred with significant changes in total biomass, especially when plants grew at higher densities in monocultures and mixtures. The sensitivity of wild oat to intensification of UV-B radiation at higher densities in mixtures was greater than that at lower densities. At all densities examined, wheat grown in mixture was significantly less sensitive to UV-B radiation than that in monoculture, and just the opposite for wild oat. The density of monocultures did not alter the response index (RI) of wheat and wild oat to enhanced UV-B radiation.

AB:   The inhibitory action on photosystem II of four sorgoleone analogues, isolated from Sorghum bicolor (L) Moench, and two synthetic inhibitors, diuron and bentazone, was tested by measuring oxygen evolution of thylakoid membranes. The inhibitors of oxygen evolution for mixtures of inhibitors was compared with the Additive Dose Model (ADM). ADM assumes that, at a defined response level, the effect of a mixture of inhibitors can be unambiguously expressed by the potency of either of the inhibitors applied separately. The slope of the logistic dose-response curves differed between the inhibitors; sorgoleone analogues had the steepest and bentazone the shallowest slope. The difference in slopes makes the interpretation of the isoboles less general and may reflect the differences in the interaction between the natural and the synthetic inhibitors with the binding site. The results suggest that there may be some limitation to ADM, namely that compounds with the same site of action might have different response curves if their mechanism of binding is different. The joint action of inhibitors follows ADM at I(50). Therefore, the inhibitors can replace each other in any mixture ratio, based on the relative potencies of the pure inhibitors, without changing each other's effect on oxygen evolution. The joint action at I(20) and I(80) sometimes diverged from ADM.

AB:   There is a growing interest in the use of soil microbial inoculants as an alternative biological approach to a) improve soil quality, b) enhance the growth, yield and guality of crops, and c) reduce the inputs of chemical fertilizers and pesticides in agriculture worldwide. One such product that has received considerable attention, is Effective Microorganisms or EM; it consists of mixed cultures of beneficial microorganisms. A long-term field experiment was conducted at Faisalabad, Pakistan to determine the agronomic and economic merits of EM in a rice-wheat cropping system. Treatments were applied in a randomized complete block design that included: control (untreated); recommended chemical fertilizer (NPK); green manure (GM); farmyard manure (FYM); Effective Microorganisms (EM) alone; NPK + EM; GM + EM; and FYM + EM. Significantly higher grain and straw yields for both crops were obtained with NPK alone, with other treatments in the following order: NPK > GM > FYM > EM. However, when fertilizer and organic amendments were combined with EM, higher grain and straw yields were obtained for each crop following the same order, i.e., NPK + EM > GM + EM > FYM + EM. The GM + EM treatment produced grain and straw yields for each crop that approached those for NPK alone. In all cases, the grain and straw yields from EM alone were higher than the controls. With few exceptions, EM applied in combination with NPK, GM and FYM caused a significant increase in nutrient uptake by the grain and straw of each crop. The uptake of NPK by both crops was higher for EM alone than for the controls. A comparative economic analysis of the treatments showed a significantly higher net return due to EM.
       The average net profit from rice and wheat production using EM was $44.90 ha-1 and $62.35 ha-1, respectively. The study indicates that EM can enhance maximum economic yields in a rice-wheat rotation and also improve soil productivity when applied with organic amendments.

AB:   We developed a method for inducing sexual outcrosses in the homothallic Ascomycete fungus Gibberella zeae (anamorph: Fusarium graminearum). Strains were marked with different nitrate nonutilizing (nit) mutations, and vegetative compatibility groups served as additional markers in some crosses. Strains with complementary nit mutations were cocultured on carrot agar plates. Ascospores from individual perithecia were plated on a minimal medium (MM) containing nitrate as the sole nitrogen source. Crosses between different nit mutants segregated in expected ratios (3:1 nit-:nit+) from heterozygous perithecia. Analysis of vegetative compatibility groups of progeny of two crosses indicated two and three vegetative incompatibility (vic) genes segregating, respectively. For rapid testing of sexual recombination between nit mutants, perithecia were inverted over MM to deposit actively discharged ascospores. Development of prototrophic wild type colonies was taken as evidence of sexual recombination. Strains of G. zeae group 2 from Japan, Nepal, and South Africa, and from Indiana, Kansas, and Ohio in the United States were sexually interfertile. Four group 1 strains were not interfertile among themselves or with seven group 2 strains. Attempts to cross G. zeae with representatives of F. acuminatum, F. avenaceum, F. culmorum, F. crookwellense, F. oxysporum, and three mating populations of G. fujikuroi were not successful.

AB:   Two isolates of the barley net blotch pathogen (Pyrenophora teres f. teres), one possessing high virulence (0-1) and the other possessing low virulence (15A) on the barley cultivar Harbin, were crossed and the progeny of the mating were isolated. Conidia from cultures of the parent and progeny isolates were used as inoculum to determine the inheritance of virulence in the pathogen. Of the 82 tested, 42 exhibited high virulence and 40 exhibited low virulence on 'Harbin' barley. The data support a model in which a single, major gene controls virulence in P. teres f. teres on this barley cultivar (1:1 ratio; chi(2) = 0.05, P = 0.83). Preparations of DNA were made from parental and progeny isolates, and the DNA was subjected to the random amplified polymorphic DNA (RAPD) technique in a search for molecular genetic markers associated with the virulence phenotype. Five RAPD markers were obtained that were associated in coupling with low virulence. The data indicate that the RAPD technique can be used to tag genetic determinants for virulence in P. teres f. teres.

In three experiments, X. translucens pv. translucens was spray inoculated onto 10 day old wheat seedlings over a range of inoculum densities (10(4), 10(5), 10(6), 10(7), and 10(8) CFU/ml). Lesions developed most rapidly on plants inoculated with higher densities of X. translucens pv. translucens. Leaf associated pathogen population sizes recovered 48 hours after inoculation were highly predictive of BLS severity 7 days after inoculation (R(2) = 0.970, P < 0.0001). The relationship between pathogen population size on leaves and subsequent BLS severity was best described by the logistic model. Leaf associated X. translucens pv. translucens population size and BLS severity from a particular pathogen inoculum density often varied among experiments; however, the disease severity level caused by a particular leaf associated X. translucens pv. translucens population size was not significantly different among experiments. Biological and disease control implications of the X. translucens pv. translucens population size-BLS severity relationship are discussed.

AB:   Aflatoxins are toxic, highly carcinogenic secondary metabolites of Aspergillus flavus and A. parasiticus, which when produced during fungal infection of a susceptible crop in the field or after harvest contaminate food and feed and threaten human and animal health. Although there are several management strategies that may reduce aflatoxin contamination of corn, the preeminent strategy for elimination of aflatoxin is to develop preharvest host resistance to aflatoxin accumulation. This strategy has gained even greater prominence due to recent discoveries of natural resistance in corn that can be exploited in plant breeding strategies. The ability to identify resistant corn genotypes has been enhanced by the development of a laboratory kernel screening assay and by a strain of A. flavus genetically engineered to produce beta-glucuronidase, an enzyme whose activity can be monitored to assess the degree of fungal infection in kernels. Investigations of resistant corn genotypes have associated kernel pericarp wax characteristics with resistance, identified kernel proteins associated with resistance to and inhibition of fungal growth or aflatoxin biosynthesis, and identified chromosome regions associated with resistance to Aspergillus ear rot and aflatoxin production. Such research advances could lead, in the near future, to commercially available, agronomically acceptable corn lines with multiple preharvest resistances to aflatoxin contamination.

AB:   Many of the lepidopterous insects which attack sweet corn, Zea mays L., are susceptible to insecticidal proteins produced by Bacillus thuringiensis ssp. kurstaki (Berliner) (Btk). Transgenic sweet corn expressing a synthetic cry gene for production of a Btk-insecticidal protein may provide a more environmentally acceptable means of sweet corn production. Eight transgenic sweet corn hybrids containing a synthetic gene for CryIA(b) protein production (BT11 event) were evaluated for resistance to the corn earworm, Helicoverpa zea (Boddie), and fall armyworm, Spodoptera frugiperda (J.E. Smith). Laboratory tests revealed that all Btk sweet corn hybrids were highly resistant to leaf and silk feeding by neonate 3 and 6 d old corn earworm larvae. Ear damage in the field to the Btk sweet corn hybrids caused by corn earworm was negligible. All Btk sweet corn hybrids, except Btk 95-0901, were moderately resistant to leaf and silk feeding by the fall armyworm. Survival and weight gain were reduced when neonates were fed excised whorl leaves of the Btk plants. Weight gain, but not survival, was reduced when 3- and 6-d-old fall armyworm larvae were fed excised whorl leaves of the Btk plants. Btk sweet corn hybrids appear to be ideal candidates for use in integrated pest management (IPM) programs for both the fresh and processing sweet corn markets, and their use should drastically reduce the quantity of insecticides currently used to control these pests in sweet corn. With appropriate cultural practices, it is highly unlikely that Btk sweet corn will contribute to the development of resistance to Btk proteins in these insects because of the high toxicity of the Cry proteins expressed in.
       these sweet corn hybrids and the harvest of sweet corn ears from fields before larvae can complete development.

AB:   In the lower Rio Grande Valley of Texas, the pyralid stalkborers Eoreuma loftini (Dyar) and Diatraea saccharalis (F.) damage approximately equal to 20% of sugarcane internodes annually. We quantified the relationships between stalkborer damage and sugar yield and quality to estimate the monetary loss incurred at these levels of damage. We also compared damage estimates and sugar quality between 2 important varieties in the region. 'NCo 310' and 'CP 70-321'. NCo 310 showed greater mean percentages of bored internodes (19.4%) than CP 70-321 (10.9%). Sugar per ton also was greater in CP 70-321 (215.97 lb/t or 108 g/kg) than in NCo 310 (190.92 lb/t or 95.5 g/kg); as were juice purity and mean sucrose content. Other variables (sugar per acre, cane per acre, fiber, ash, and stalk weight) did not differ significantly between the 2 varieties. Sugar per acre, juice purity, stalk weight, cane per acre, sucrose per ton of sugarcane, and sucrose content all were inversely related to percentage of bored internodes. Ash content increased with damage, consistent with a plant displaying symptoms of stress. Regression slopes for CP 70-321 were steeper than for NCo 310, perhaps suggesting that although CP 70-321 usually displays less damage, yield and quality maybe affected more severely in the event of borer damage because of its higher sugar content. In Texas, the share agreements between farmers and the sugar mill mandate that the mill retains 40% of proceeds as compensation for milling, with economic losses also shared in the same ratio. Assuming the value of raw sugar is $420/t (907.18 kg), 20% bored internodes results in a loss of $1,181.04/ha ($477.96 acre). For average Texas sugarcane acreage of 18,200 ha (45,000.
       acres), total losses would be $21.5 M ($12.9 M to the producers and $8.6 M to the mill). The ineffectiveness of insecticides and their abandonment by Texas sugarcane growers make it imperative that pest management alternatives, such as resistant varieties and biological control agents, be investigated to alleviate the losses.

AB:   Red imported fire ants, Solenopis invicta Buren, are known to feed upon planted field crop seed; however, the relationship with varying levels of seed water content is not known. If red imported fire ants are feeding on planted seed during periods of slow seed germination, and if the seed are more palatable or otherwise more easily damaged at elevated water contents, the risk of crop-stand loss is increased. In this study, 5 types of field crop seeds--wheat, Triticum aestivum L.; corn, Zea mays L.; grain sorghum, Sorghum bicolor (L.) Moench; cotton, Gossypium hirsutum L.; and soybean. Glycine max L.--were exposed to red imported fire ants under laboratory conditions to measure damage caused by feeding. The seeds were dry and on moistened filter paper for maximum rate of germination, and at 20, 40, and 60% water contents for various parts of the study. Moistened seed suffered 2-90 times more damage in 48 h than comparable dry seed. When commercial sorghum seed was tested at 4 initial water contents, seed damage increased approximately equal to 22 times over damage to dry seed, A model was developed to predict the feeding damage to commercial sorghum seed as a function of elapsed time and seed water content. The risk of feeding damage relative to germination increased up to as much as 20 times when the initial water content was 60% compared with dry seed, except for corn damage, which was relatively insensitive to water content. We conclude from laboratory studies that crop-stand losses are likely to be most severe for wheat and grain sorghum when moistened seed are exposed to feeding by red imported fire ants.

AB:   Strip intercropping of corn may provide spatial and temporal diversity for management of extended-diapause corn rootworm populations. Strip-intercropped corn may sustain infestations of corn rootworm larvae attributable to migration of larvae into 1st-yr corn from soil previously planted to corn. Row-specific distribution of corn rootworm eggs and adult emergence were determined in a strip intercropped system, and effects of interstrip cultural and insecticidal treatments on rootworm infestation of outer rows were evaluated. Corn rootworm eggs were found in all rows of strips previously planted to corn. Root injury ratings were significantly higher in the outer rows than in the interior rows of corn adjacent to the previous year's corn strips. Oilseed meal and insecticide treatments were associated with lower corn rootworm adult emergence and larval root injury than was found in untreated plots. Higher rootworm adult emergence and root injury scores in tillage treatments, where the soil was disturbed by ripping with a cultivator shank, were attributed to increased soil pore space that facilitated larval movement into adjacent corn strips. Fewer adults emerged and less root injury occurred in outer rows of corn adjacent to soybean strips that were subjected to interrow soil compaction from wheel traffic. In severely infested fields, deliberate compaction of interrow soil or incorporation of cruciferous plant material into soil between strips are possible noninsecticidal management options for reducing severe corn rootworm infestation of outside rows of corn in strip intercropping systems.

AB:   Soil erosion is a major threat to sustaining agricultural production in Tanzania. However, quantitative information is scanty on its effects on yields of major crops for principal soils and management practices. We conducted this study to determine erosion effects on soil moisture, related properties and corn yield on Tropeptic Haplustox and Ultic Haplustalf soils at Mlingano in Tanzania. Four erosion classes (least, slight, moderate, and severe) on Tropeptic Haplustox and three erosion classes (slight, moderate, and severe) on Ultic Haplustalf were established according to the thickness of the Ap horizon under natural field conditions. Accelerated soil erosion reduced soil moisture content, soil organic carbon, available water capacity and water use efficiency. Mean volumetric soil moisture content (average of both soils) during the growing season was 23.3% for severe, 24.8% for moderate, and 25.7% for slight erosion. Mean soil organic carbon content was 1.15% for severe, 1.64% for moderate and 1.97% for slight erosion. Mean available water capacity was 2.6 cm for severe, 3.5 cm for moderate, and 4.0 cm for slight erosion. Soil bulk density and excessive degree days of soil temperature above 25 degrees C increased with severity of erosion. These adverse changes accentuated constraints on crop growth and reduced corn (Zea mays) yield on severely eroded soil by 45% and 59% for Tropeptic Haplustox and Ultic Haplustalf soils, respectively. The water use efficiency of corn was 21.6 kg ha-1 cm-1 in the least eroded class versus 17 kg ha-1 cm-1 in the severely eroded class for the Tropeptic Haplustox, and 23 kg ha-1 cm-1 in the slightly eroded and 18.1 kg ha-1 cm-1 in the severely eroded class for Ultic.

AB:   The effects of contour live barriers of vetiver and pennisetum on soil erosion were studied on four small farms in south central Honduras. Paired plots were installed and soil erosion measured by changes in the soil surface level of transects 0.3 and 6.0 m up the slope from the barrier. After three years, transects 0.3 m above the barriers significantly retained eroded soil compared with control transects. Soil accumulation by barriers ranged from 2.6 to 11.2 cm, and natural terrace formation (the difference between the barrier and corresponding control transect) ranged from 5.2 to 13.8 cm. No difference was detected between barrier and control for the transects 6.0 m above the barrier. Deposition in front of the barriers and reduction in surface rilling were apparent to farmers. Erosion from up slope on the barrier plots and from both transects in the control sections was not obvious. Direct measurement and farmer observation of sediment deposition by live barriers will help evaluate farmer-identified species for future use. The deposition helps farmers become aware of sheet erosion before the effects of soil degradation on crop yields become grossly apparent and soil fertility restoration becomes too costly for small-scale farmers.

AB:   The purpose of the present studies was to screen for suitable cover crops and seeding rates and investigate the influence of non-suppressed and mechanically suppressed living mulch on white cabbage yield, weed growth, pest damage and green manuring effects. Because no differences in weed suppression between the species/cultivars were found in the first experiment, Trifolium repens L. cv. Pertina, which had least negative impact on cabbage yield was chosen for the second experiment. In addition, Trifolium subterraneum L. cv. Geraldton was included. The competition between cover crop and cabbage was considerable in the second experiment. Mowing once or twice did not improve cabbage yield compared with unmowed treatments. A considerable increase in cabbage yield was achieved both in subclover and white clover by rototilling between the rows 6 weeks after transplanting. The cover crops did not reduce weed biomass or number of weeds early in the season compared with monoculture, but weed biomass in late summer became significantly lower in living mulch. Rototilling was more effective for weed suppression than mowing. Cover crop combined with rototilling reduced weed biomass by 89% compared with untreated monoculture. Subclover living mulch gave the earliest and most ground coverage and the lowest cabbage yield, but it also gave the least insect damage. Both subclover and white clover living mulches gave significantly more marketable cabbage heads than monoculture due to less insect damage. However, damage from caterpillars, primarily Mamestra brassicae L., was too great in all treatments to produce a commercially viable crop. White clover intercropping in cabbage gave.
       significantly higher oat (Avena sativa L.) yield the subsequent year than monocropping. The implications of the current findings on future efforts to improve intercropping are discussed.

AB:   Oviposition in soybean fields by western corn rootworm, Diabrotica virgifera virgifera LeConte, is threatening the effectiveness of crop rotation in east-central Illinois and adjoining counties in northwestern Indiana. Attraction to soybean, Glycine max L., plants has been hypothesized as a mechanism underlying rootworm oviposition in soybean fields. In this study, female western corn rootworms were allowed to fly freely for 0.5 h within a wind tunnel array of potted soybean and corn, Zea mays L., plants before rootworm distribution patterns on corn and soybeans were determined. Test insects were collected in corn and soybean plantings from both within and outside of areas where adults oviposit in soybean fields. We found no evidence of an increased tendency for rootworms from various populations to be associated with soybeans regardless of collection location, cropping history at the collection site, or the area's status with respect to western corn rootworm oviposition in soybean fields. The difference between corn and soybean plant height influenced postflight distribution of adults in the wind tunnel. More rootworms accumulated on plants whose foliage projected above the height of the insect release platform. Distance moved during a 0.5-h period of free flight was greatest when the foliage of nearby plants did not extend above the level of the insect release platform. Regardless of how corn and soybean plants were configured in the wind tunnel, a significantly greater proportion of rootworms was recovered on corn plants. We found no evidence for attraction to soybeans based on postflight plant association.

AB:   Exposure to different constant temperatures (12, 17, 22, 27 or 32 degrees C) during the entire life-span of female Lysiphlebia mirzai variously affected its longevity, life-table parameters, developmental rate, and mortality of developmental stages of the progeny. The parasitoid develops much faster at 32 degrees C than 12 degrees C. Lower threshold temperature for the development (t1) was 3.02 degrees C and predicted time-to-adult 339.93 degree days. Higher percent mortality occurred at 32 degrees C and 12 degrees C than at 22 degrees C. The adult survived much longer (17 days) at the lower extreme temperature than at the higher one. However, net fecundity (daughters/female) and total fecundity rates (progeny/female) were lowest at 12 degrees C. The female produced the highest number of daughters (163.8) and progeny (242.6) at 22 degrees C. Life-table parameters were temperature dependent; r(m) was greater than 0.3 at >(or)= 22 degrees C. The results reveal an optimum range of temperatures at which L. mirzai performs well. Most of the life-table parameters vary little between 17 and 27 degrees C, thus, the parasitoid may he adapted for a wide range of temperatures and thus well suited for biocontrol of the cereal aphid Rhopalosiphum maidis, in areas where temperatures vary within this range, as in the plains of north India.

AB:   Fertilizer trials involving application of phosphorus (P) as both rock phosphate and superphosphate were conducted on adjacent organic and conventional farms in SE-Australia in 1991 and 1992. Seed P concentration and seed P content (P concentration multiplied by seed mass) were higher on the organic farm in 1991 when rainfall was below average, but were higher on the conventional farm in 1992, a wetter year. Addition of superphosphate increased seed P content and concentration on both farms in 1991 and on the organic farm in 1992. These results indicated that seed produced on a conventional farm with addition of fertilizers containing soluble P is likely to have a significantly greater seed P content than seed produced on an organic farm with application of rock phosphate or with no fertilizer addition. Seed harvested from these trials were sorted into small and large seeds to provide seed with a wide range of P contents: 29-169 micrograms. Heavier seeds had a higher P content. Seeds were germinated and grown for three weeks in field soil in a glasshouse. Heavier seeds were more likely to have germinated after 48 h. Seedling shoot dry mass after three weeks was significantly positively influenced by seed P concentration and seed mass, that is, shoot dry mass positively correlated with seed P content. Root dry mass after three weeks also correlated positively with seed P content. However, seedling relative growth rate was not correlated with seed P content. Seed nitrogen content and concentration did not significantly influence seedling growth. The origin of the seed, that is, whether it was produced on an organic or conventional farm, the year it was harvested, and the fertilizer treatment the parent.
       crop had received all did not significantly affect seedling growth. Enhanced early growth of seedlings may be particularly important on organic farms where herbicides are not applied and seedlings may face increased weed competition. It is suggested that organic farmers may benefit from grading out heavier seeds for sowing.

AB:   Experiments were conducted to investigate the host and host age preference of Trichogramma galloi Zucchi and T. pretiosum Riley when reared from the eggs of Diatraea rufescens Box (Lepidoptera: Pyralidae), D. saccharalis F., or Sitotroga cerealella Olivier (Lepidoptera: Gelechiidae). The effect of the host on host preference was weak or absent, because the majority of the test females of both Trichogramma species attacked eggs of a certain host first. T. galloi females did not recognize eggs of S. cerealella as a potential host, suggesting that females of this species need additional olfactory cues for host recognition. Furthermore, relative host size had a noticeable effect on choice of the first host by T. galloi. The larger eggs of D. rufescens were preferred over eggs of D. saccharalis. This was not the same for females of T. pretiosum; the majority of them attacked the small eggs of S. cerealella first. Eggs of B. rufescens were accepted to a lesser extent and eggs of B. saccharalis were rejected. In choice experiments, females of T. galloi consistently preferred younger eggs of B. rufescens over older ones. In nonchoice situations, only 4-d-old host eggs were parasitized less commonly by both T. galloi and T. pretiosum and had a lower number of progeny allocated to them. Five-day-old hosts were never parasitized. Nevertheless, there was a clear-cut relation between host age and time lapse before the 1st host acceptance. The implications of these results for learning in Trichogramma and for candidate species selection in biological control are discussed.

AB:   The 1st step in developing microbials as alternatives to chemical insecticides is to determine susceptibility of insects and virulence of the microbials in the laboratory. Anagrapha falcifera multiple nucleopolyhedrovirus (AfMNPV) and 3 Bacillus thuringiensis products, HD-1-S-1980, XenTari, and Javelin, were bioassayed against neonate Ostrinia nubilalis (Hubner), Helicoverpa zea (Boddie), and Spodoptera frugiperda (J. E. Smith) by using a droplet feeding method. The virulence of the B. thuringiensis materials for H. zea and S. frugiperda was Javelin > XenTari > HD-1-S-1980 and for O. nubilalis it was Javelin > XenTari and HD-1-S-1980. AfMNPV was most virulent to H. zea, followed by S. frugiperda, and O. nubilalis. The effect of XenTari and AfMNPV mixtures on the mortality of the 3 corn ear pests also was examined. Mixtures of entomopathogens either had no effect on mortality when compared with both pathogens alone or mortality caused by the virus was reduced with the addition of B. thuringiensis.

AB:   Restriction enzyme-mediated DNA integration (REMI) mutagenesis was used to identify mutants of Magnaporthe grisea impaired in pathogenicity. Three REMI protocols were evaluated and the frequency of REMIs determined. An REMI library of 3,527 M. grisea transformants was generated in three genetic backgrounds, and 1,150 transformants were screened for defects in pathogenicity with a barley cut leaf assay. Five mutants were identified and characterized. Two mutants (2029 and 2050) were impaired in appressorium function. Two other mutants, 125 and 130, were altered in conidial morphology, conidiogenesis, and appressorium function. Mutant 130 was also a methionine auxotroph and methionine auxotrophy and segregated with the reduction in pathogenicity. An additional mutant, 80, showed reduced pathogenicity on blast-susceptible rice cultivars but was fully pathogenic on barley. The reduction of pathogenicity in mutant 80 was associated with a delay in conidial germination and appressorium development. Genetic analysis suggested single-gene segregation for each mutant, but only two of the mutations co-segregated with the hygromycin resistance marker. The genetic loci in mutants 2029, 2050, 125, 130, and 80 were termed PDE1, PDE2, IGD1, MET1, and GDE1, respectively. pde1 and pde2 were non-allelic to cpkA, a mutation in the catalytic subunit of cyclic AMP (cAMP)-dependent protein kinase A with a very similar phenotype. The results indicate the utility of REMI for studying fungal pathogenicity, but also highlight the requirement for rigorous genetic and phenotypic analysis.

AB:   A near-saturated sorghum genetic linkage map was produced using RFLP, AFLP and morphological markers. First a composite, essentially RFLP-based genetic linkage map was obtained from analyses of two recombinant inbred populations. This map includes 343 loci for 11 linkage groups spanning 1352 cM. Since this map was constructed with many previously mapped heterologous probes, it offers a good basis for synteny studies. Separately, an AFLP map was obtained from the analysis of 168 bands revealed from 12 primer pair combinations. It includes 137 loci for 11 linkage groups spanning 849 cM. Taking into account the different data sets, we constructed a combined genetic linkage map including 443 loci spanning 1899 cM. Two main features are to be noted: (1) the distribution of AFLPs along the genome is not uniform; (2) an important stretching of the former core map is induced after adding the AFLPs.

AB:   Flag-leaf angle (FLAngle), flag-leaf area (FLarea) and flag-leaf area duration (FLADuration) are important traits in determining yield in wheat (Triticum aestivum L). Genetic studies on these traits are very few. The objective of this study was to determine the gene action controlling those traits in four wheat crosses. Six generations were available for each cross: parents (P1 and P2), F1, F2 and backerosses (BC(F1 x P1) and BC(F1 x P2,)). The joint scaling test described by Mather and Jinks was used to test goodness of fit to eight genetic models. Models including additivity, dominance and interallelic interactions best fitted the data for the three traits and the four crosses. Additive effects were most prevalent for FLAngle. They were also significant for FLArea and FLADuration. Dominance and epistatic gene action were also found, but the degree and direction was both trait- and genotype-specific. Heritabilities values were intermediate. Genetic progress, although slow, can be expected when selecting for these traits; however, selection would be most effective if delayed to later generations because of dominance and epistatic effects.

AB:   Effectiveness of indirect selection for grain yield was investigated among eight bread wheat lines, selected in a stress environment in the East African Highlands, where they showed a wide response to yellow rust, the biotic factor causing the stress. The lines were intercrossed to give an 8 x 8F1 diallel, which was grown in this same environment for three consecutive growing seasons during 1994 and 1995. Half of the last trial was sprayed with fungicide. From the estimates of narrow-sense heritabilities for yield and yellow rust severity, and the genetic correlation between them, indirect selection for yield in the unsprayed plots, obtained by choosing the most resistant 5% of this material was, on average, 12% higher than selecting for yield itself. In the fungicide-treated plots, indirect selection was only 73% as efficient as direct selection. The implications of these results for selecting for yield in stress environments are discussed.

AB:   The barley gene Mlo encodes a prototype of a novel class of plant proteins. In mlo mutants, absence of the 60 kDa wild-type Mlo protein results in broad-spectrum resistance to the powdery mildew fungus, Erysiphe graminis f. sp. hordei. To directly assess its function, Mlo was transiently expressed with a marker gene encoding a modified green fluorescent protein (GFP) in leaf epidermal cells of mlo resistant barley lines. Fungal inoculation of epidermal cells transfected with wild-type Mlo led to haustorium formation and abundant sporulation. Therefore, expression of the wild-type Mlo gene, in mlo resistant genotypes, is both necessary and sufficient to restore susceptibility to fungal attack. Complementation of mlo resistance alleles was restricted to single host cells, indicating a cell-autonomous function for the wild-type Mlo protein. We discuss our findings with respect to source-sink relationships of plants and biotrophic fungi and the potentially wide-ranging use of the transient complementation assay to analyse host compatibility and defence in response to powdery mildew attack.

AB:   In rice, silencing of the aleurone-specific Ltp2-gus transgene, causing easily detectable staining patterns on the grain surface, offers a convenient tool to study quantitative aspects of gene silencing in monocots. In this paper we analyzed phenotypes, occurrence, inheritance and environmental effects on the silencing. We also report on the cloning of transgenes, determination of their structure and analysis of transcripts from the transgene loci. The results show that various patterns of silencing appeared in the R2 generation at which most of the transgenes became homozygous and that they were inherited for five generations. In addition, silencing independently occurred in three generations and reversion to full expression was also found. Cloning of transgenes from a silenced L3.3 line demonstrated that this line carried two transgene loci: one carried an intact Ltp2-gus gene and the other carried a rearranged transgene in which part of the gus gene was in the antisense orientation. Analysis of gus transcripts indicated that partial antisense RNA derived from the rearranged transgene was present in silenced lines and was polyadenylated but that it was absent in non-silenced lines. RNA analyses suggested that the Ltp2-gus silencing in the aleurone layer was post-transcriptional and that it may be caused by interaction of partial antisense gus transcripts with normal sense transcripts. Possible involvement of antisense transcripts in post-transcriptional silencing is discussed.

AB:   The genetic structure of the rym5 locus was studied in a population comprising 391 doubled-haploid lines that were evaluated for resistance to two strains of Barley Yellow Mosaic Virus (BaYMV-1, 2) and to Barley Mild Mosaic Virus (BaMMV). The absence of recombinants that are able to differentiate between the reaction to these different bymoviruses provides evidence that rym5 is a complex locus, which is either composed of several closely linked genes or of an allelic series of a single gene. For marker-assisted introgression of this locus into adapted barley germplasm, a CAPS (cleaved amplified polymorphic sequence) and a microsatellite marker were developed that flank the gene at distances of 0.8 and 1.3% recombination, respectively.

AB:   Chromosome locations for gene orthologues of the dormancy-related maize transcription factor VIVIPAROUS-1, encoded by the Vp1 locus on maize chromosome 3, were determined in wheat (Triticum aestivum L.) and rice (Oryza sativa L.) via linkage to markers on existing molecular maps using a cDNA of a wheat Vp1 orthologue as a probe in genomic Southern analyses. Vp1-orthologous loci were detected on the long arms of wheat chromosomes 3A, 3B and 3D [Xlars 10 (taVp1) loci] and rice chromosome 1 (osVp1), in line with previous evidence of synteny between these regions of the rice and wheat genomes and chromosome 3 of maize. The wheat loci mapped some 30 cM from the centromeres and some 30 cM proximal to the red grain (R) loci that control seed colour and coat-imposed dormancy. This unequivocal, genetic separation of the Vp1 and R loci may offer an opportunity for improving resistance to pre-harvest sprouting in wheat by combining the coat-imposed dormancy associated with red seed colour and true embryo dormancy regulated by Vp1.

AB:   This study has analyzed the molecular basis and genetic behaviour of the polymorphism generated by the amplification of barley genomic DNA with primers complementary to microsatellites. Primers anchored at the 5' end, used alone or in combination with arbitrary sequence primers, generated random amplified microsatellite polymorphisms (RAMPs). Unanchored primers were also used as single primers in a microsatellite primed-PCR (MP-PCR). Twenty six randomly selected RAMP DNA fragments which showed polymorphism between the cultivars Steptoe and Morex were cloned and sequenced. All sequences showed the expected repeated motif at the end of the insert, with the number of repeats ranging from five to ten. Genomic sequences containing low numbers of microsatellite motifs were preferentially amplified: therefore, only a fraction of the polymorphism could be attributed to variation in the number of microsatellite motifs at the priming site. Some sequences contained either cryptic simple sequences or members of families of repeated DNA. Polymorphism at the internal cryptic simple sequences was detected by RAMP bands inherited as co-dominant markers. Four MP-PCR bands were cloned and sequenced. A number of repeats identical to the primer itself were found at each end of the insert. Two allelic bands were polymorphic for an internal microsatellite. The potential use of cloned bands as fingerprinting tools was investigated by employing them as hybridization probes in Southern blots containing digested barley DNA from a sample of cultivars. RAMP probes produced complex hybridization band patterns. MP-PCR probes produced either a highly variable single locus or low-copy number loci.
       Segregations for 31 RAMPs and three MP-PCR bands were studied in a population of 70 doubled-haploids from the Steptoe/Morex cross. One third of all markers were co-dominantly inherited. Markers were positioned on an RFLP map and found to be distributed in all barley chromosomes. The new markers enlarged the overall length of the map to 1408 cM.

AB:   Reductions of incidence of chewing ear pests produced by application of adherent granular malathion were associated with reductions of mycotoxigenic fungi in each of 4 yr. In a 2-yr study, the incidence of potentially mycotoxigenic Fusarium fungi was significantly reduced by a single hand application of 0.1% (AI) granules at 11 kg granules/ha (0.011 kg/ha [AI]) compared with control plots, and was approximately equal to plots receiving 5 sprays of malathion at 1.1 kg/ha (AI) each. In a 2nd series of studies at this site, the use of 1% malathion granules at 11 kg granules/ha (0.11 kg/ha [AI]) significantly reduced the incidence of chewing corn ear insect pests and visible Fusarium mold in 2 corn hybrids that differed in relative resistance to Fusarium moniliforme Scheld. Different rates of adherent malathion granules were applied with conventional equipment in a small-plot study near Metamora, IL. Because of poor coverage in the ear zone, control of insects and indirect control of Fusarium ear mold was limited. Although year and hybrid effects were involved, there was generally a positive association between insect damage and incidence of mold in the 1994 and 1995 hand-application studies. Relative insect damage at harvest was significantly correlated with fumonisin levels of the hybrids treated in 1995. Thus, in addition to the economic and environmental benefits derived from using granules containing low malathion compared with conventional formulations for insect control described previously, use of these granules also may indirectly reduce ear molds and associated mycotoxins in corn.

AB:   Lotus corniculatus plants transformed with a maize cDNA (G1L) encoding a sulphur-rich gamma-zein were obtained by using two fusion genes: one with the CaMV 35S promoter, the other with the ribulose bisphosphate carboxylase small subunit (rbcS) promoter. The highest expression of G1L mRNA was found in plants transformed with G1L under the rbcS promoter. The steady state level of G1L mRNA in the leaves was generally directly correlated with the G1L copy number. However, due to a transcriptional block, no G1L mRNA was detected in some of the 35S-G1L multicopy transformants. Analyses with methylation-sensitive restriction enzymes revealed that the T-DNA of the silenced 35S-G1L transformants was methylated. T-DNA copy number, G1L silencing activity, and the state of methylation were strictly correlated in primary transformants. A cross between two 35S-G1L transformed plants, one (S) with the T-DNA methylated and the other (NS) without, showed that: (1) the methylated state of T-DNA passed through meiosis; and (2) when T-DNA copies from the two parents were combined in the progeny, the unmethylated T-DNA copies of parent NS became methylated at different levels and G1L mRNA production was dependent on the degree of methylation.

AB:   Domesticated rice differs from the wild progenitor in large arrays of morphological and physiological traits. The present study was conducted to identify the genetic factors controlling the differences between cultivated rice and its wild progenitor, with the intention to assess the genetic basis of the changes associated with the processes of rice domestication. A total of 19 traits, including seven qualitative and 12 quantitative traits, that are related to domestication were scored in an F2 population from a cross between a variety of the Asian cultivated rice (Oryza sativa) and an accession of the common wild rice (O. rufipogon). Loci controlling the inheritance of these traits were determined by making use of a molecular linkage map consisting of 348 molecular-marker loci (313 RFLPs, 12 SSRs and 23 AFLPs) based on this F2 population. All seven qualitative traits were each controlled by a single Mendelian locus. Analysis of the 12 quantitative traits resolved a total of 44 putative QTLs with an average of 3.7 QTLs per trait. The amount of variation explained by individual QTLs ranged from a low of 6.9% to a high of 59.8%, and many of the QTLs accounted for more than 20% of the variation. Thus, genes of both major and minor effect were involved in the differences between wild and cultivated rice. The results also showed that most of the genetic factors (qualitative or QTLs) controlling the domestication-related traits were concentrated in a few chromosomal blocks. Such a clustered distribution of the genes may provide explanations for the genetic basis of the "domestication syndrome" observed in evolutionary studies and also for the "linkage drag" that occurs in.
       many breeding programs. The information on the genetic basis of some desirable traits possessed by the wild parent may also be useful for facilitating the utilization of these traits in rice-breeding programs.

AB:   Susceptibility of Heliothis virescens (F.), Helicoverpa zea (Boddie), Pseudoplusia includens (Walker), Spodoptera exigua (Hubner), and Spodoptera frugiperda (J.E. Smith) to purified endotoxins and commercial formulations of Bacillus thuringiensis Berliner was measured in a wide range of colonies collected from 8 states in the U.S. Cotton Belt during 1992 and 1993. Results indicated that field-collected colonies of H. virescens, H. zea, P. includens, and S. frugiperda were as susceptible as laboratory-reared colonies and those reported in the literature to the purified endotoxin proteins Cry1Ac and Cry1Ab or the commercial formulations Javelin WG, Dipel ES, and Condor OF in diet-treated assays. Colonies of S. exigua collected from transgenic cotton expressing endotoxin protein had elevated median lethal concentrations (LC50S) compared with a colony collected from nontransgenic cotton or those from laboratory colonies. Ranges of LC50S for field-collected colonies of H. virescens generally were similar to the ranges observed for laboratory colonies and similar to those reported in the literature. Wider ranges of variation in LC50S were observed among populations of H. zea and S. exigua than among populations of the other species. However, the highest LC50S observed for H. zea was no higher than those reported in the literature. Only a few colonies of P. includens and S. exigua were tested. P. includens susceptibility was generally greater than that of H. virescens and less than that of H. zea. S. frugiperda was the least susceptible species studied. Variability in LC50S obtained with Cry1Ac (r = 0.702) correlated with variability in LC50S for Cry1Ab across.
       13 colonies of H. virescens exposed to both proteins. Colonies of H. zea and H. virescens were pooled into single colonies and selected with the insecticidal proteins to produce endotoxin-resistant strains. Selection for resistance in H. virescens was not successful, but a strain of H. zea was selected that had elevated LC50S (10 times) after 2 generations and very high LC50S compared with a susceptible laboratory strain (100 times) after 8 generations, suggesting that H. zea has the genetic capacity to develop resistance to endotoxin proteins.

AB:   Many studies have shown that molecular markers can improve the efficiency of the selection of quantitative traits in plant breeding provided that large population sizes are used. As a way to limit experimental costs it appears that the use of unreplicated trials may be more valuable than the use of replicated plots in one trial. In this particular context of unreplicated large trials, spatial heterogeneity within the field may reduce the efficiency of the selection. The problem of controlling spatial heterogeneity was seldom considered in the case of marker-assisted selection (MAS). Here, we propose an integrated method to predict genetic values considering simultaneously marker information and possible spatial heterogeneity. This method was applied to a population of 300 F3 lines of maize evaluated in 11 unreplicated trials for grain yield. We show that when spatial field heterogeneity is considered through appropriate statistical models the accuracy of genetic value predictions is improved and the same genetic gain can be achieved with a reduced number of trials.

AB:   Defense response (DR) genes are a broad class involved in plant defense. In this study we mapped 36 probes representing seven classes of defense response genes. This collection of probes represents genes involved in the hypersensitive response (HR), pathogenesis-related (PR) genes, genes for the flavonoid metabolic pathway, genes encoding proline/glycine-rich proteins, ion channel regulators, lipoxygenase, lectin, and others. Using nullisomic-tetrasomic lines of 'Chinese Spring', we were able to assign at least 167 loci to the 21 chromosomes of wheat. Homoeologous group 7 chromosomes possessed the most DR loci followed by group 2. Sixty-two loci were placed on existing genetic linkage maps of wheat. Map locations indicated that the DR gene loci are not randomly distributed throughout the wheat genome, but rather are located in clusters and/or in distal gene-rich regions of the chromosomes. Knowledge of the chromosomal locations and genome organization of DR genes will be useful for candidate gene analysis of quantitative trait loci.

AB:   Three genotypes of Pearl millet were screened in vitro for induction of embryogenic callus, somatic embryogenesis and regeneration. Shoot apices excised from in vitro germinated seedlings or immature embryos isolated from green house established plants were used as primary explants. The frequency of embryogenic callus initiation was significantly higher in shoot apices in comparison with immature zygotic embryos. Moreover, differences between genotypes were minimal when using shoot apices. Friable embryogenic calli (type II) developed on the initial nodular calli after 1 to 3 months of culture. The frequency of type II callus is related to the composition of the maintenance medium and they were more often found in ageing cultures. The transfer of embryogenic calli onto auxin-free medium was sufficient for inducing somatic embryo development in short-term culture (3 months) while a progressive loss in regeneration potential was observed with increasing time of subcultures. Maturation of embryogenic calli on medium supplemented with activated charcoal, followed by germination of somatic embryos on medium supplemented with gibberellic acid, restored regeneration in long-term cultures.

AB:   A crossover study was performed using 24 dairy cows to investigate whether pure ethanol in concentrations that could be found in well-fermented silages influenced milk composition or flavor. Cows were fed a standard ration of well-fermented grass silage for ad libitum intake and high moisture barley and a protein concentrate in restricted amounts. A daily dose of ethanol (600 g) was divided into three meals/d and fed with grass silage. When cows received ethanol, milk yields decreased slightly, but milk fat and protein concentrations increased so that energy-corrected milk yield increased by 0.9 kg/d. Milk concentrations of lactose and urea decreased, concentrations of ethanol and acetone increased, concentrations of free fatty acids increased slightly, and alpha-tocopherol concentrations were unaffected. The proportion of palmitic acid in milk fat increased, and the proportion of unsaturated acids decreased. Organoleptic milk quality was reduced because of an increase in milk tainted by feed flavors. The off-flavor could not be attributed solely to the ethanol transmitted to the milk. Precautions should be taken to avoid extensive production of ethanol during fermentation of grass silage and other feeds that are to be fed to dairy cows.

AB:   This study compared effects of exogenous bovine somatotropin (bST) on the performance of early lactation cows fed diets differing in ruminally degradable starch. Thirty-two Holstein cows (24 multiparous) in early lactation (5 d in milk) were divided into four groups and fed diets containing 39% grain as steam-flaked sorghum or steam-rolled corn with or without exogenous bST for 90 d. Grain processing did not affect dry matter intake as a percentage of body weight or yields of milk, but steam-rolled corn improved efficiency of feed utilization during the first 45 d of the study. Cows receiving bST had lower dry matter intake during the first 45 d of treatment. Milk yield and efficiency of feed utilization were increased by bST treatment, and milk yield response was greater during the first half than during the second half of the study. Milk composition and yield of milk components did not differ among treatments. Flaked sorghum increased in vitro starch hydrolysis and digestibilities of dry matter, organic matter, and starch, but neither method of grain processing nor bST affected digestibilities of crude protein, acid detergent fiber, or neutral detergent fiber. Grain type did not affect milk yield, and responses to bST were lower from 7 to 13 wk than from 1 to 6 wk prepartum.

AB:   A study was conducted using lactating Holstein cows with ruminal and duodenal cannulas in a 4 X 4 Latin square design to investigate fibrolytic enzyme supplementation on site and extent of nutrient digestion. The four diets consisted of 45% concentrate, 10% barley silage, and 45% cubed alfalfa hay (dry matter basis) and differed in enzyme supplementation: 1) control cubes, 2) cubes treated with 1 g of enzyme mixture/kg of cubes, 3) cubes treated with 2 g of enzyme mixture/kg of cubes, and 4) both concentrate and cubes treated with 1 g of enzyme mixture/kg of dry matter. The enzyme supplement contained primarily cellulase and xylanase activities. Digestion of organic matter and neutral detergent fiber in the total tract was higher for cows fed the high dosage of enzyme than for cows fed the control cubes. Ruminal digestibility of crude protein was higher, but that of organic matter and neutral detergent fiber was only numerically higher, for cows fed the high dosage of enzyme compared with that of cows fed the control cubes. Higher ruminal digestibility associated with the high dosage of enzyme resulted in more microbial protein synthesis. Milk production increased for cows fed the high dosage of enzyme compared with cows fed the control cubes end effects of the addition of enzyme on milk composition were minimal. The results demonstrated the benefits of using a fibrolytic enzyme additive to enhance feed digestion and milk production by dairy cows. The response to enzyme supplementation was affected more by amount of enzyme than by whether the enzyme was added to forage or concentrate.

AB:   Four lactating, cannulated Holstein cows were used in a 4 X 4 Latin square design to investigate the effects of grain source and fibrolytic enzyme supplementation on ruminal fermentation, nutrient digestion in the rumen and in the intestine, and milk production. A 2 X 2 factorial arrangement was used; two grains (barley and hull-less barley) were combined with and without enzyme. The enzyme supplement (Pro-Mote; Biovance Technologies Inc., Omaha, NE ) contained primarily cellulase and xylanse activities and was applied daily to the total mixed diet. Dry matter intake was not affected by diet, but starch intake was greatest when hull-less barley was fed. Starch from hull-less barley was more digestible in the rumen and in the total tract than was starch from barley, but opposite results occurred for fiber digestion, indicating that hull-less barley depressed fiber digestion. As a result, cows fed the hull-less barley diets tended to produce more milk with a higher milk lactose content than did cows fed the barley diets. Enzyme supplementation had minimal effects on ruminal digestion but increased nutrient digestibility in the total tract and the proportion of microbial N in nonammonia N. Consequently, cows fed diets supplemented with enzyme had a higher milk protein content and tended to produce more 4% fat-corrected milk than did control cows. These results indicate that the use of hull-less barley rather than barley increased the digestible energy intake of dairy cows, resulting in higher milk production. The use of a fibrolytic enzyme mixture enhanced feed digestibility and milk production.

AB:   The extractability of the corn cob xylan, particularly its water-soluble component (ws-X), was studied using extraction methods with and without application of ultrasound in water and aqueous NaOH. The results indicate that ws-X comprise a variety of xylan polymers differing in the proportion of side chains composed of single arabinose and glucuronic acid side chains and 2-O-beta-D-xylopyranosyl-alpha-L-arabinofuranose moieties. The xylan fractions were characterized by yield, composition, structural features, molecular properties and biological response in mitogenic and comitogenic thymocyte tests. Compared to the classically extracted xylans, the ws-X prepared by the assistance of ultrasound had the same primary structure features and similar or slightly higher stimulatory activities in both tests.

AB:   Knowledge of the biological significance underlying quantitative trait loci (QTLs) for disease resistance is generally limited. In recent years, advances in plant-microbe interactions and genome mapping have lead to an increased understanding of the genes involved in plant defense and quantitative disease resistance. Here, we report on the application of the candidate-gene approach to the mapping of QTLs for disease resistance in a population of wheat recombinant inbreds. Over 50 loci, representing several classes of defense response (DR) genes, were placed on an existing linkage map and the genome was surveyed for QTLs associated with resistance to several diseases including tan spot, leaf rust, Karnal bunt, and stem rust. Analysis revealed QTLs with large effects in regions of putative resistance (R) genes, as previously reported. Several candidate genes, including oxalate oxidase, peroxidase, superoxide dismutase, chitinase and thaumatin, mapped within previouslv identified resistance QTLs and explained a greater amount of the phenotypic variation. A cluster of closely linked DR genes on the long arm of chromosome 7B, which included genes for catalase, chitinase, thaumatins and an ion channel regulator, had major effects for resistance to leaf rust of adult plants under conditions of natural infestation. The results of this study indicate that many minor resistance QTLs may be from the action of DR genes, and that the candidate-gene approach can be an efficient method of QTL identification.

AB:   Holstein bull calves were used to examine the effect of dry feed on water balance and fecal moisture content during the suckling period. In Experiment 1 (n = 20 calves), free access to concentrate and timothy hay decreased urine volume and increased apparent water retention, fecal water excretion, and fecal moisture content by 2 wk, although daily amounts of milk replacer also affected water balance when DMI from dry feed was low. In Experiment 2 (n = 20 calves), free access to concentrate and hay from wk 1 increased reabsorption of water from renal tubules during wk 2, resulting in reduced urine volume and increased plasma volume. In Experiment 3 (n = 10 calves), supplementation of 500 g/d of milk replacer plus free access to concentrate and hay from wk 1 increased plasma antidiuretic hormone by 2 wk compared with the concentration in calves receiving 200 g/d of milk replacer alone. Plasma antidiuretic hormone concentrations were highly correlated with plasma concentrations of acetate and ketone bodies but not with glucose and urea. In Experiment 4 (n = 16 calves), apparent water retention and fecal moisture content during wk 2 were increased by free access to concentrate from wk 1 but were not affected by rice straw as an inert bulk source.

AB:   Soil compaction due to traffic and natural reconsolidation limits the ability of crop roots to expand into deep zones of moisture availability. This study was conducted to determine whether the total absence of traffic substantially improved the resulting soil condition. Extensive cone index measurements were used to evaluate the soil strength resulting from 5 years of a cotton (Gossypium hirsutum L.)-wheat (Triticum aestivum L.) double cropping experiment. Four cotton tillage systems, including a conservation tillage practice of in-row subsoiling and planting into wheat residue stubble, and two traffic systems were analyzed. The USDA-ARS Wide-Frame Tractive Vehicle was used to control traffic in the experimental plots. Contour graphs of cone index were used to determine differences in tillage and traffic systems. Traffic was found to reconsolidate soil that was initially completely disrupted to a 0.51 m depth into a soil condition similar to one that had never received a subsoiling treatment.  Traffic was also found to decrease the total soil volume estimated for root growth using a 2 MPa limiting cone index value, but not the maximum rooting depth beneath the row, when an annual in-row subsoiling practice was used.

AB:   Proteins extracted from suspension cultured cells of rice were separated by two-dimensional polyacrylamide gel electrophoresis. The separated proteins were electroblotted onto a polyvinylidene difluoride membrane and 103 electroblotted proteins were analyzed. The N-terminal amino-acid sequences of 20 out of 103 proteins were determined in this manner. N-terminal regions of the remaining proteins could not be sequenced and they were inferred to have a blocking group at the N-terminus. Internal amino-acid sequences of 32 proteins were determined by sequence analysis of peptides obtained by Cleveland peptide mapping. The amino-acid sequences determined here were compared with those of known plant and animal proteins. Furthermore, the concanavalin A-peroxidase method was used to determine which of the 103 proteins were glycosylated, and in vitro and in vivo phosphorylation was carried out to identify some of the phosphorylated proteins. Using this experimental approach, we could identify the major proteins involved in growth and development of rice cell suspension cultures and discuss on the physiological function of some of these identified proteins including the calcium binding protein, superoxide dismutase and rice ascorbate peroxidase.

AB:   Sugarcane, commonly referred to as Saccharum officinarum, is currently divided into six species, two of them are wild and four exist only in cultivation. The two wild species and three of the cultivated ones are interfertile and have produced the interspecific hybrids that constitute the sugarcane of commerce. All species are represented by wide ranges of intergrades preserved as clones through vegetative propagation. Species are separated by variable floral characters, sugar content, chromosome numbers and epidermal hair groups. Floral characteristics are sometimes useful with clones that flower, sugar is present in widely overlapping ranges and is highly influenced by environment, chromosome numbers range from 36 to 170 in the genus and range widely within species, and some epidermal hair groups are more quantitative than qualitative. Molecular techniques show that Saccharum spontaneum is distinctly different from the other species in cytoplasmic DNA, and cluster analyses of nuclear DNA support the difference. Not only are the species interfertile but chromosomal pairing and recombination have been demonstrated, as has the possibility that some Saccharum species are hybrids of others. Taken together, these observations suggest that there is little basis for the present separation and that the six species should more properly consist of two: one being S. spontaneum, based on molecular data, and the other S. officinarum including the other four species and all interspecific hybrids.

AB:   Two convenient and efficient microculture techniques (liquid droplet and shallow-layered culture) were used to rear 2-day-old and 3 to 4 day-old proembryos in rice. Among four cultivars, growth rate and frequency of embryogenesis were higher in the japonica cultivars than in the indica cultivars during proembryo culture. Two-day-old proembryos could grow and form callus only in Km8p and N6 among four kinds of tested media, and plantlets regenerated via organogenesis. Plant regeneration from callus initiated from three- and four-day-old proembryos occurred through somatic embryogenesis and organogenesis. For in vitro embryogenesis it was essential to supplement the medium with 14 amino acids and coconut milk. The highest frequency of embryogenesis and the frequency of total induction after 14 days of culture were approximately 42% and 95% for 3-day-old proembryos, and 45% and 100% for 4-day-old proembryos, respectively.

AB:   Different pretreatments were given to anthers of barley before culturing, and their effects assessed on the frequency of embryos and green doubled haploid plants produced. Mannitol pretreatment was better than cold pretreatment for some low responding cultivars. Optimal concentration of mannitol for pretreatment depended on cultivar. Low responding genotypes needed a higher concentration of mannitol than responsive ones. The addition of Ficoll to liquid medium increased the number of embryos and green plants. The influence of the growth regulators 2,4-D and TIBA was assayed using ten cultivars of barley grown in Spain. The anti-auxin TIBA gave good embryo production with some of the low responding cultivars. Two row-type cultivars always produced higher number of embryos and green plantlets than six row-type. The application of these modifications to 10 F1 hybrids with potential agronomic value, allowed the production of almost 1000 doubled haploid plants from only 3500 anthers. Up to two doubled haploid plants per flower were produced from the cross Monlon X Sonja.

AB:   Wheat plants, 22d. old, were exposed to wide range of soil water osmotic potential (psi(s) = 0 to -1.2 MPa) induced by NaCl and CaCl2 treatments in combination with roots maintained under aerobic (drained at field capacity) or nonaerobic (flooded) conditions in the soil, and sprayed with 10 mg L-1 kinetin solution. In drained plants, not receiving kinetin, increased soil salinity resulted in appreciable inhibition of shoot growth and reduction in chlorophyll (Ch1.), soluble sugars (SS) contents and grain yield. Shoot growth, Ch1. content, soluble sugars and grain yield were significantly lower for flooded plants than unflooded analogues over the entire psi(s) range. Both salinity and waterlogging synergize to increase Na+, Ca2+ and Cl- accumulation in shoot tissues and to decrease the stability of leaf membranes to either dehydration (40% polyethylene glycol 6000) or heat (51 degrees C) stress. The ratio of K+/Na+ transported to shoots under aerobic and anaerobic conditions decreased progressively on salinization. The association between the internal mineral element concentrations was largely affected by kinetin treatment. Kinetin application ameliorated the deleterious effects of salinity and oxygen deficiency. It reduced Na+, Ca2+ and Cl- accumulation and improved K+ uptake under salinity and waterlogging stresses. Increased K+/Na+ ratio helped the plants to avoid Na+ toxicity and enhanced shoot growth and grain yield. Kinetin also reduced membrane injury by dehydration and heat stresses and improved the water status of plants under both aerobic and anaerobic conditions. The effects of single factors (Soil salinity 'psi(s)', soil waterlogging 'WL' and Kinetin 'Kin').
       and their interactions (psi(s) x WL, psi(s) x Kin, WL x Kin and psi(s) x WL x Kin) were shown by analysis of variance to be statistically significant for most parameters tested. Calculation of the coefficient of determination (eta (2)) led to three important findings. (1) Salinity (psi(s) was dominant in affecting leaf relative water content (RWC), shoot dry mass, grain yield, stability of leaf membranes to dehydration stress and the contents of Na+, Ca2+, Mg2+ and Cl-. (2) Kinetin (Kin) had a dominant effect on the stability of leaf membranes to heat stress as well as on chlorophyll and soluble sugars contents. (3) The share of waterlogging (WL) was dominant for K+ content. It can be concluded that kinetin application helped wheat plants to grow successfully in the areas subjected to combined effects of salinity and oxygen deficiency, such as in salt marshes.

AB:   Bale silage is usually made from long or restricted cut grass. Long cut herbage may be difficult to ensile, because of delayed and heterogenous fermentation. The aim of the present study was to find the optimal composition and level of an additive based on a mixture of hexamine, ie hexamethylene-tetraamine (HMTA) and sodium nitrite (NaN) together with sodium benzoate (NaB) and sodium propionate (NaP) to restrict aerobic deterioration. The silage crop (318 g DM kg-1; 158 g CP, 98 g ash, 89 g WSC, a buffering capacity of 200 mE and an ME value of 8.7 MJ per kg DM) consisting of about 30% ryegrass (Lolium perenne L), 30% meadow fescue (Festuca pratensis L) and 40% timothy (Phleum pratense L) was harvested by a self-loading wagon. Grass was ensiled in 41 PVC laboratory silos. Silos of each treatment were either closed immediately with a water-seal or aerated with 2.31 air per 24 h during the first 12 days of ensiling. Silages were treated with additives containing different concentrations and combinations of HMTA, NaN, NaB and NaP. Formic acid treated silage and untreated silage were used as controls. A mixture of HMTA and NaN (KSQ) improved fermentation by reducing pH, butyric acid, ammonia and increasing lactic acid and residual water-soluble carbohydrates (WSC) concentrations. This mixture also reduced the number of Clostridium spores in the silage. Addition to 300 g HMTA and 450 g NaN ton-1 FM was satisfactory to improve fermentation and restrict clostridial activity, but the aerobic stability of the silage was low. Addition of organic acid salts was more effective and improved both fermentation and storage stability. NaB (800 g) or a mixture of 690 g NaB and 210 g NaP was satisfactory to.
       control aerobic stability. The use of HMTA and NaN in combination with NaB and NaP resulted in high hygienic quality and storage stability of silage made from unchopped and wilted grass.

AB:   Quantification of sucrose, glucose and fructose is essential for developing a physiological understanding of growth and development of plant species. This is usually achieved by either HPLC or enzymatic assays for specific sugars. The need for reliable and cost-effective assays of large numbers of samples led us to compare microtitre plate-adapted enzymatic assays for sucrose, glucose and fructose with current HPLC protocols. The enzymatic assay techniques were modified without loss of precision or accuracy when compared to the original protocols. Application of HPLC and the modified enzymatic assay to a range of sugarcane stem extracts found no difference in assay sensitivity. The enzymatic assay had considerable advantages in terms of sample throughput and cost-effectiveness.

AB:   Hydrolysis of urea associated with different component parts (surface and subsurface soil from unplanted and planted fields and standing water) of tropical flooded rice soil was investigated. Urea hydrolysis followed a first-order kinetics with surface soil having the highest urease activity followed by subsurface soil and flood water. Urea hydrolysis varied with the crop growth stage and was more pronounced at tillering and panicle stages under greenhouse conditions and at maturity stage under field conditions. A certain degree of cultivar variation on urease activity at both surface and subsurface soil was also noticed. Urea hydrolysis was considerably higher in soils from green manure amended field plots than that of control and urea amended plots. Results indicate that addition of green manure to a flooded soil, while increasing microbial activity could also enhance urea hydrolysis.

AB:   Five different cultivars of sorghum seeds infected with a varied degree of Fusarium moniliforme were treated with biocontrol agents. Pure cultures of Pseudomonas fluorescens, Trichoderma harzianum and Chaetomium globosum at the rate of 1 X 10(8) cfu g-1 and talcum based formulations of (28 X 10(7) cfu g-1) (19 X 10(7) cfu g-1) and (4 X (4 X 10(6) cfu g-1) at the rate of 6 g kg-l and 10 g kg-1 of seeds were used, respectively. The treated seeds were evaluated for per cent reduction of F moniliforme, seed germination, vigour index and field emergence. It was found that the pure culture of P fluorescens was more effective in reducing the F moniliforme infection followed by T harzianum and C globosum than the Bavistin treated and untreated seeds. Formulations of P fluorescens were effective in reducing the F moniliforme infection and also in increasing the seed germination, vigour index and field emergence, followed by T harzianum and C globosum treatments in comparison with control.

AB:   Transgenic maize plants have been generated by particle gun bombardment that overproduce a Nicotiana plumbaginifolia L. manganese superoxide dismutase (MnSOD). To target this mitochondrial enzyme into chloroplasts, the mature MnSOD-coding sequence was fused to a chloroplast transit peptide from a pea ribulose-1,5-bisphosphate carboxylase gene, whereas expression of the chimeric gene was driven by the CaMV 35S promoter. Transgenic MnSOD activity contributed to 20% of the total SOD activity. The presence of transgenic MnSOD had clear effects on foliar tolerance to chilling and oxidative stress. The results suggest that overproduction of MnSOD in the chloroplasts increases the antioxidant capacity of the leaves.

AB:   Aldehyde oxidase (AO, EC 1.2.3.1) proteins in leaves, roots and seeds of barley (Hordeum vulgare L.) plants were studied. Differences in substrate specificity and mobility in native PAGE between AO proteins extracted from roots, leaves and seeds have been observed. Four clear bands of AO reacting proteins were detected in barley plants capable of oxidizing a number of aliphatic and aromatic aldehydes such as indole-3-aldehyde, acetaldehyde, heptaldehyde, and benzaldehyde. Mouse polyclonal antibodies raised against purified maize AO cross-reacted with barley AO proteins extracted from roots, leaves and seeds. At least three different AO proteins were detected in roots on the basis of their mobility during PAGE after native Western blot analysis while in leaves and seeds only one polypeptide cross-reacted with the antibody. SDS-immunoblot analysis showed marked differences in molecular weight between subunits of the AO bands extracted from roots, leaves and seeds. Two distinct subunit bands were observed in roots, with relatively close molecular weights (160 kDa and 145 kDa), while a single subunit with a molecular weight of 150 kDa was observed in leaf and seed extracts. Menadione, a specific and potent inhibitor of animal AO did not affect barley AO proteins. Root and leaf AO differed in their thermostability and susceptibility to exogenous tungstate. The AO proteins in plants may be a group of enzymes with different substrate specificity, tissue distribution and presumably fulfilling different metabolic roles in each plant organ.

AB:   Soil disturbance may reduce the effect of mycorrhizae on plant growth and nutrient uptake through its effects on the integrity of the extraradical hyphal network. A growth-chamber experiment was conducted to evaluate the survival of extraradical arbuscular mycorrhizal (AM) fungal hyphae when detached from the host root system, and to understand the effects of soil disturbance on the ability of these hyphae to colonize plant roots and to reestablish mycorrhizal associations in previously disturbed soils. The experiment consisted of establishing AM fungi in pots divided into two compartments by a nylon mesh (37 micrometers), by growing corn (Zea mays L.) in one of the compartments for 6 weeks in an unsterilized agricultural field soil. The mesh prevented the growth of corn roots from one side of the pot to the other, while allowing the passage of the AM hyphae. After establishment of AM fungi the following treatments were performed: soil in the two compartments was either disturbed by sieving through 2 mm mesh (D) or undisturbed (U) leading to four combined disturbance treatments: (1) both compartments undisturbed (UU); (2) root compartment disturbed and root-free compartment undisturbed (DU): (3) root compartment undisturbed and root-free compartment disturbed (UD); and (4) both compartments disturbed (DD). The effects of fallows of four different durations: 0, 30, 60 and 90 d were also measured in the same experiment giving a total of 16 treatments. Soils were disturbed at the beginning of the experiment in the root compartment, and after each fallow period in the root-free compartment. Immediately after disturbance of the soil in the root-free compartment, corn was planted and grown for 30 d to.
       test the combined effects of fallow and soil disturbance on AM formation and nutrient content. Soil disturbance had no adverse effect on AM efficiency if test plants were planted immediately after disturbing the root-free compartment. However, AM efficiency decreased with increasing length of fallow. Lengths of total and metabolically active extraradical hyphae in the root-free compartments were measured before each fallow. Significantly less hyphal lengths were observed in pots where the soil of the root compartment had been disturbed. Test plant shoot weight was highest in UU and lowest in DD treated pots. Phosphorus content by the test plants was twice as high in UU as in DD. Test plants in undisturbed (UU) pots had greater Zn and Cu contents than in DU, UD or DD pots. Content of P, Zn and Cu in test plants was reduced by about 40%, 63% and 70%, respectively by 90 d of fallow, compared to 0 d fallow.

AB:   The use of plants to detoxify contaminated soil sites has the potential to be a cost-effective alternative to traditional remediation technologies. However, plant-bacteria interactions in contaminated soils are not well understood. In this study we investigated the effect of bacterial seed inoculants on the rhizosphere community during the reduction of 2-chlorobenzoic acid (2CBA) concentrations by Dahurian wild rye (Elymus dauricus). Soil was amended with 450 mg 2CBA kg(-1) and aged for 2 yr at which time the detectable amount of 2CBA was 61 mg kg(-1). Dahurian wild rye inoculated with either Pseudomonas aeruginosa strain R75, P. savastanoi strain CB35 or a 1:1 mixture of these bacteria was grown in aged contaminated soil for 56 d in a growth chamber. The potential of rhizosphere soil to degrade 3-chlorobenzoic acid (3CBA), a contaminant with a similar degradation pathway to 2CBA, versus 2,3-dichlorobenzoic acid (23diCBA) or 2,5-dichlorobenzoic acid (25diCBA), contaminants with pathways dissimilar to 2CBA, was also assessed. Inoculating Dahurian wild rye with the mixed inoculum had decreased the extractable 2CBA from 61 to 29 mg kg(-1), 56 d after planting but had no effect on plant growth. Inoculating Dahurian wild rye with a mixture of strains R75 and CB35 increased the potential of rhizosphere microorganisms to reduce 3CBA concentrations by 17% but had no effect on amounts of 23diCBA or 25diCBA. In a sterile hydroponic plant growth system, inoculation of Dahurian wild rye had no effect on 2CBA concentrations; although, the inoculum became established and grew in the hydroponic solution indicating that inoculants required an unknown soil factor to degrade 2CBA. Bacterial seed inoculants.
       selectively enhanced the potential of the rhizosphere community to degrade certain compounds without affecting heterotrophic bacterial communities.

AB:   We investigated whether long-term management of a Haplic Phaeocem (FAO) influences organic C, microbial biomass and enzyme activities in the bulk soil and in particle size fractions. The following treatments were used; (1) no fertilization (control), (2) NPK, (3) 20 t FYM ha(-1) (farmyard manure), (4) 20 t  FYM ha(-1) + NPK, (5) 30 t FYM ha(-1) and (6) 30 t FYM ha(-1) + NPK. The fertilizers were applied to plots of a crop rotation (sugar beet, potatoes, winter wheat, spring barley, alfalfa); inorganic fertilizers were applied every year, FYM was applied every second year. Particle size fractions were obtained by low-energy sonication (0.25 kJ g(-1)) and a combination of wet sieving and centrifugation, releasing the size fractions 2000-250, 250-63, 63-2, 2-0.1 and < 0.1 micrometers. FYM increased microbial biomass, N-mineralization, urease, arginine deaminase and alkaline phosphatase activity of the bulk soil, whereas the effect of additional NPK fertilization depended on the enzyme assayed. Xylanase activity of the bulk soil was mainly influenced by the quality and quantity of the residues and by the amount of below-ground plant biomass. C and N contents (related to fraction dry weight) increased with diminishing particle size. The mean recoveries of C and N contents after the fractionation procedure were 96.8 and 97.1%, respectively. Organic amendments (20 vs 30 t FYM ha(-1)) induced an equal increase of organic C and total N in all particle size fractions (2000-250, 250-63, 63-2, 2-0.1 and < 0.1 micrometers). Unfertilized soils were characterized by a higher C-to-N ratio of the particles (2000-250 and 250-63 micrometers) than the organically and inorganically.
       fertilized soils. Microbial ninhydrin-reactive N was recovered to 73.6% after the fractionation procedure. Highest concentrations of ninhydrin-reactive N were found in the clay (2-0.1 micrometer) and silt fraction (63-2 micrometers), lowest in the coarse sand fraction (2000-250 micrometers). The increased ninhydrin-reactive N in the bulk soil after long-term amendment with FYM is mainly attributed to an increase of ninhydrin-reactive N in the clay and silt fractions. Therefore, long-term organic amendments increased the capacity of the small-sized fractions to protect soil microorganisms. Urease activity was mainly located in the 63-2 and 2-0.1 micrometers fractions, whereas the coarse and fine sand particles accumulated disproportionately higher amounts of xylanase. The predominance of xylanase and urease in different particle size fractions depends apparently not only on the location of soil microorganisms and their substrates but also on the mechanisms of enzymes to adsorb and bind onto mineral and organic particles.

AB:   The effects of long-term agricultural management on active soil organic matter (SOM) and short-term microbial C and N dynamics were investigated. Short-term changes in chemical and biological variables after incorporating fresh rye shoots were measured in intact soil cylinders from three contrasting agricultural systems. Two of the soils were from organic or conventional 4-yr rotations which had been in place for 6 yr as part of the University of California at Davis Sustainable Agriculture Farming Systems (SAFS) project and the third was from a double-cropped, intensive vegetable production system in the Salinas Valley of California. Microbial biomass (MB) and respiration, numbers of organisms in several trophic groups, soil inorganic N, dissolved organic C and recoverable rye were measured before and during the 6 weeks following rye incorporation. Active soil organic matter, expressed as the ratios of microbial biomass C or N to total soil C or N, respectively, appeared to be related to long-term management. These ratios increased in proportion to increased organic inputs and reduced tillage or periods of fallow. In all soils, MBC increased and decreased rapidly following rye incorporation, but MBN was fairly constant. Significant differences among the soils in MBC and MBN were maintained over the 6 week experiment. Following rye incorporation, fluorescein diacetate (FDA) active counts of bacteria and bacterial-feeding nematodes increased rapidly, whereas changes in FDA active fungal hyphal lengths and fungal-feeding nematodes were less pronounced. The rates of rye decomposition, respiration and net N mineralization were highest the first week after incorporation, coincident with increases in MBC.
       and numbers of active bacteria in all three soils. There were significant differences among soils in numbers of organisms in the trophic groups on some sample dates, but changes in soil respiration and inorganic N and the rate of rye decomposition remained similar in all three soils. The SAFS organic soil had a somewhat lower ratio of bacterial to fungal biomass and lower ratio of respiration to MBC throughout the experiment than the SAFS conventional soil. Despite long-term differences in agricultural management and differences in active SOM contents among the three soils, the rates of rye decomposition and C and N mineralization were similar. Rye incorporation produced a short-term burst of microbial growth and activity of similar magnitude in all three soils although the initial MB contents in the three soils were different. Variations among the soils in FDA active counts of fungi and numbers of bacterial- and fungal-feeding nematodes indicated that microbial community composition was more responsive to rye incorporation than were changes in soil C and N pools.

AB:   The spatial heterogeneity and the temporal variability of N2O emission rates were examined in an arable soil. The N2O emission rates were measured using soil cover boxes. Rates were measured systematically at regular distances (7 m) on a sampling grid (9 rows x 9 columns) across a field plot site (60 x 63 m). There were two sampling periods, one before (March, 4 flux rate measurements) and one after (May, 6 flux rate measurements) a field experiment with three crops and three N-fertilization rates was laid out on an uniformly-managed area. The observed N2O emission rates were approximately log-normally distributed. The spatial variability of the N2O flux rates was high (coefficients of variation > 150%), resulting from a few areas with extremely high N2O emission rates (hot spots). Total N2O losses were not influenced by the experimental treatments, but their spatial distribution within the area changed with treatment. Differences in mineral soil N due to N-mineralisation, N-fertilisation and plant uptake were responsible for these changes. The spatial pattern of the N2O flux rates persisted for only 1 d, indicating a high temporal variability.

AB:   Lipase mediated interesterification of acylglycerols from corn oil with conjugated linoleic acid (CLA) was studied in several organic solvents. Two commercially available lipases, IM-60 from Mucor miehei and Chirazyme L-2 from Candida antarctica brought about greatest extents of interesterification. Hexane was the best solvent from the standpoint of both maximizing the reaction rate and the extent of interesterification.

AB:   We investigated whether alpine and lowland Poa species exhibit inherent differences in leaf cuticular waxes, leaf UV absorbing compounds and/or growth responses to UV-B treatment. All plants were grown hydroponically in a growth cabinet (constant 20 degrees; 14 hr photoperiod; 520 micromoles photons m-2 s-1 PAR). Two alpine (P. fawcettiae and P. costiniana), one sub-alpine (P. alpina) and three temperate lowland species (P. pratensis, P. compressa and P. trivialis) were grown under conditions without UV radiation for 36 days. In a subsequent experiment, four Poa species (P. costiniana, P. alpina, P. compressa and P. trivalis) were also exposed for 21 days to UV-B/(UV-A) radiation ('UV-B treatment') that resulted in daily UV-B radiation of 7.5 kJ m-2 day-1, with control plants being grown without UV-B ('UV-A control treatment'). All treatments were carried out in the same growth cabinet. There was no altitudinal trend regarding wax concentrations per unit leaf area, when the six species grown under UV-less conditions, were compared at similar developmental stage (20-30 g shoot fresh mass). However, large differences in cuticular wax chemical composition were observed between the alpine and lowland species grown under UV-less conditions. For example, a single primary alcohol was present in the waxes of the lowland and sub-alpine species (C26H53OH), but was virtually absent in the alpine species. Although alkanes were present in all six species (primarily C29H60 and C31H64), the proportion of total wax present as alkanes was highest in the alpine species. Aldehydes were only present in the waxes of the alpine species. Conversely, substantial amounts of triterpenoids were mainly present.
       in the three lowland species (squalene and lupeol were the dominant forms). The proportion of total wax present as long-chain esters (LCE-s) was similar in all six species grown in the absence of UV radiation. Acetates were observed only in the wax of P. trivialis. Of the four species exposed to UV-B, only P. costiniana and P. compressa showed any differences in wax chemical composition (compared to UV-A control plants). In P. costiniana, the proportion of total waxes present as alkanes was substantially lower in the UV-B grown plants (replaced by an unknown compound with a high retention time value). UV-B grown P. costiniana and P. compressa both exhibited less wax per unit leaf area. In P. compressa, this resulted from a lower absolute amount of alcohol per unit leaf mass in the UV-B treatment. The concentrations of UV absorbing compounds in whole leaf extracts differed between the four investigated species. However, no systematic differences were apparent between the alpine, sub-alpine and lowland species. Exposure to UV-B radiation had no effect on the specific leaf area (ratio of leaf area to leaf dry mass). We conclude that the alpine and lowland Poa species have a cuticular wax composition that is inherently different.

AB:   Dehydration-induced proteins and other osmo-protectants enable plants to survive dehydration stress. The object of this study was to determine whether dehydration-induced proteins from wheat seeds could protect turkey sperm and improve survival and function after liquid storage. A partially purified heat-soluble protein extract was isolated from dry, mature wheat seed embryos and added to semen diluent. Hens were inseminated with either fresh or semen stored 24 h at 5 C and fertility and hatchability data collected. The addition of 10% wheat protein extract to semen stored 24 h at 5 C improved fertility and hatchability of eggs over semen stored in diluent alone (P < 0.05). The heat-soluble proteins isolated from wheat seed embryos are capable of protecting turkey sperm during in vitro storage and could potentially improve long-term storage of sperm from other species.

AB:   A total of 600 commercial strain (DeKalb) Single Comb White Leghorn hens, 80 wk of age, were used in this study to determine the effects of different induced molting programs on production and immune parameters. The hens were randomly divided into four treatment groups (three experimental and one control) of 150 hens each. The hens in the first treatment group were fed a layer ration containing 20,000 ppm of zinc for 5 d, and received a reduced photoperiod of 8 h/d for 5 d (Zn group). In the second group, feed was withdrawn for 10 d, the photoperiod was reduced to 8 h/d and oyster shell and water were provided for ad libitum consumption. At Day 11, hens consumed corn and oyster shell ad libitum until Day 30 and at Day 31, hens were returned to a full feed layer ration and received 16 h of light/d [California treatment (CAL group)]. In the third treatment, light was reduced to 8 h/d, and oyster shell was provided for ad libitum consumption until Day 60. Feed and water were removed for the first 2 d and on Days 4, 6, and 8. On Days 3, 5, 7, and 9, hens were fed 45 g of feed per hen. On Day 10 until Day 60, hens were fed 90 g/hen and at Day 61, hens were returned to the layer ration ad libitum and received 16 h of light/d [on-again, off-again program (ON-OFF group)]. The last group served as controls (CONT). Body weight, egg production, egg size, internal egg quality, shell weight, and mortality were determined. Total circulating leukocytes, differential leukocyte counts, and antibody production were also measured. The results demonstrated that induced molting significantly increased egg production from 64% to 77 to 83%, Haugh units from 80.4 to 85.9 to 87.3.
       and shell weight from 5.3 g to 6.3 to 6.4 g when compared to CONT. The body weight of the molted hens decreased significantly to 84.8, 74.5, and 88% of the initial body weight for Zn, CAL, and ON-OFF groups, respectively. The total circulating leukocytes was significantly lower in molted hens than in CONT hens. Differential leukocyte counts were affected by all induced molting programs and the heterophil to lymphocyte ratio was significantly increased, reaching 0.61, whereas that of CONT was only 0.20. Antibody production was largely unaffected by any of the induced molting programs.

AB:   Phytosiderophores, mugineic acids, have been demonstrated to be involved in Fe acquisition in gramineous plants. In this study, chromosomal arm locations of genes encoding for biosynthesis of various phytosiderophores were identified in a cultivar of barley (Hordeum vulgare L. cv. Betzes). Using wheat (Triticum aestivum L. cv. Chinese Spring)-barley (cv. Betzes) ditelosomic addition lines for 4HS and 4HL, a gene for hydroxylation of 2'-deoxymugineic acid to mugineic acid was localized to the long arm of barley chromosome 4H. To locate the gene for hydroxylation of mugineic acid to 3-epihydroxymugineic acid, hybrids between the 4H addition line and other wheat-barley addition lines were studied. Only a hybrid between 4H and 7H addition lines produced 3-epihydroxymugineic acid. The gene was further localized to the long arm of chromosome 7H by feeding mugineic acid to ditelosomic addition lines for 7HS and 7HL. A new phytosiderophore was discovered in both 7H and 7HL addition lines, which was identified to be 3-epihydroxy-2'-deoxymugineic acid by detailed nuclear magnetic resonance studies. These results revealed that in barley there are two pathways from 2'-deoxymugineic acid to 3-epihydroxymugineic acid: 2'-deoxymugineic acid leads to mugineic acid leads to 3-epihydroxymugineic acid and 2'-deoxymugineic acid leads to 3-epihydroxy-2'-deoxymugineic acid leads to 3-epihydroxymugineic acid. Barley genes encoding for the hydroxylations of phytosiderophores are located in different chromosomes and each gene hydroxylates different C-positions: the long arm of chromosome 4H carries the gene for hydroxylating the C-2' position and the long arm of chromosome 7H carries the gene.
       for hydroxylating the C-3 position of the azetidine ring.

AB:   Allelic chlorina-f2 mutants of barley (Hordeum vulgare L.) growing under different light and temperature conditions demonstrated that the chlorophyll b-free chlorina-f2f2 and chlorina-f2(101) express a stable phenotype. Only 3 out of 10 light-harvesting chlorophyll a/b-binding proteins, Lhca4 (photosystem b, and Lhcb1 and Lhcb6 (photosystem II), required chlorophyll b for accumulation. The other light-harvesting proteins were found in all chlorina-f2 alleles, indicating that the integration pathway of these proteins into mutant thylakoid membranes was not affected. Chlorina-f2 alleles with a thylakoid membrane capable of fullfilling photosynthesis and transport demands, but with various amounts of chlorophyll b: chlorina-f2(101) (chlorophyll b-free), chlorina-f2(123) (27% of chlorophyll b compared with the wild type) and chlorina-f2(122) (70% chlorophyll b), were chosen to investigate whether chlorophyll b is necessary for the protease-stable insertion of Lhcb1 into mutant thylakoid membranes. The Lhcb1 was affected in almost all alleles and was most sensitive to chlorophyll b deficiency. The Lhcb1 antibody confirmed the heterogeneity of the polypeptides of the light-harvesting chlorophyll a/b-binding protein II (LHCII) and detected in wild-type membranes, two protease-resistant, mature forms of Lhcb1 with apparent molecular masses of 28 and 29 kDa. Only one band reacting with the Lhcb1 antibody could be detected in chlorophyll b-free chlorina-f2f2. It co-migrated with the 29-kDa band, but was completely digested after treatment of the isolated mutant membranes with exogenous protease. This showed that in chlorina-f2f2 the Lhcb1 precursor was processed at one cleavage site only.
       The resulting 29-kDa Lhcb1 was not provided with chlorophyll b, and, consequently, not properly folded and inserted into the membrane. It remained susceptible to protease and was inconvertable to a 28-kDa form.

ID:   glycine-decarboxylase. 10-formyltetrahydrofolate-synthetase.
CC:   F600; F200
AB:   Glycine-accumulating mutants of barley (Hordeum vulgare L.) and Amaranthus edulis (Speg.), which lack the ability to decarboxylate glycine by glycine decarboxylase (GDC; EC 2.1.2.10), were used to study the significance of an alternative photorespiratory pathway of serine formation. In the normal photorespiratory pathway, 5,10-methylenetetrahydrofolate is formed in the reaction catalysed by GDC and transferred to serine by serine hydroxymethyltransferase. In an alternative pathway, glyoxylate could be decarboxylated to formate and formate could be converted into 5,10-methylenetetrahydrofolate in the Cl-tetrahydrofolate synthase pathway. In contrast to wild-type plants, the mutants showed a light-dependent accumulation of glyoxylate and formate, which was suppressed by elevated (0.7%) CO2 concentrations. After growth in air, the activity and amount of 10-formyltetrahydrofolate synthetase (FTHF synthetase; EC 6.3.4.4), the first enzyme of the conversion of formate into 5,10-methylenetetrahydrofolate, were increased in the mutants compared to the wild types. A similar increase in FTHF synthetase could be induced by incubating leaves of wild-type plants with glycine under illumination, but not in the dark. Experiments with 14C showed that the barley mutants incorporated [14C]formate and [2-14C]glycollate into serine. Together, the accumulation of glyoxylate and formate under photorespiratory conditions, the increase in FTHF synthetase and the ability to utilise formate and glycollate for the formation of serine indicate that the mutants are able partially to compensate for the lack of GDC activity by bypassing the normal photorespiratory pathway.

AB:   In suspension-cultured cells of winter wheat (Triticum aestivum L. cv. Chihokukomugi), the accumulation of soluble secretory proteins in the culture medium was promoted by ABA treatment in comparison with non-treated cells. The total amount of secretory proteins in ABA-treated cells was 1.7-fold higher than that in non-treated cells. The analysis of two-dimensional electrophoresis revealed that at least twelve secretory proteins were induced by ABA, and these were named WAS (wheat ABA-induced secretory) proteins 1 to 12. N-terminal amino acid sequence analysis of WAS proteins revealed the sequences of WAS-2 and WAS-3. Homology searches showed that WAS-2 had 55% identity with the N-terminus of the wheat chemically induced gene (WCI-5 gene) product. WAS-3 was also shown to have 93% identity with the N-terminus of the barley protein R, a typical member of thaumatin-like proteins (TLPs). Immunoblot analysis also suggested that WAS-3 was related to protein R. These results suggest that exogenous ABA induces some basic secretory proteins that are related to the plant defense system in wheat.

AB:   By spraying tassels of maize (Zea mays L.) with a trifluralin solution before flowering, viable bicellular pollen grains (with one vegetative nucleus and one mitotically arrested diploid generative cell) were produced. Fertilization between a central cell (2n) of diploid plants and the mitotically arrested generative cell (2n) of the bicellular pollen induced by trifluralin treatment was detected by the presence of shriveled kernels on pollinated ears. A covered method (tassels covered with aluminum foil for 24 h after spraying) and a non-covered method were compared, and the non-covered treatment with 0.2-0.4% trefanocide solutions was the most effective treatment in producing viable bicellular pollen. About 40-50% of the kernels were shriveled on pollinated ears from the treatments. Chromosome counts on seedlings obtained from 0.3% non-covered treatment revealed 24% were triploid and 4% were aneuploid (2n = 19, 21, and 22).

AB:   An investigation was made into the relationships between six species or subspecies of the genus Hordeum that grow in the Iberian Peninsula and Balearic Islands. Plant material included samples of 19 populations of the annual species H. marinum subsp. marinum, H. marinum subsp. gussoneanum, H. murinum subsp. murinum, and H. murinum subsp. Leporinum, and the perennial species H. bulbosum and H. secalinum. Relationships were analysed using PCR-based molecular markers. Thirteen sets of primers were designed and synthesized based on sequences of mapped RFLPs from genomic libraries and conserved regions of structural genes of known function in cultivated species. Primers were used to amplify genomic DNA from all populations. The number of amplified products ranged from 1 to 18 per primer and a total of 168 markers were scored. The markers revealed different degrees of relationships. Hordeum bulbosum was clearly separated from the rest. The populations of both subspecies of H. murinum were closely related. H. marinum subsp. gussoneanum appeared to be closely related to H. secalinum, yet relatively separated from its conspecific subspecies marinum. The use of a large number of DNA markers in this kind of analysis is discussed.

AB:   We present DNA sequence data showing population variation in the intergenic spacer (IGS) regions of the ribosomal DNAs (rDNAs) on the A genomes of 27 diploid and polyploid wheats. PCRs (polymerase chain reactions) specific for the Am genome gave products with five populations of Triticum monococcum but did not give products with AABB or AABBDD wheats. PCRs specific to the Au genome of T. urartu gave products with all the AABB and AABBDD polyploids that were tested, but not with T. monococcum. AAGG tetraploids gave products only with the Au-specific primers, but the AAAAGG hexaploid T. zhukovskyi gave products with both the Au and Am primers. Phylogenetic analysis showed a substantial degree of IGS divergence for both the Am and Au genomes in diploids and polyploids compared with other genomes of Triticum and Aegilops. The rate of evolution of the IGS is much greater than previously reported for the internal transcribed region of the rDNAs but the view that the IGS only gives random noise is rejected, the IGS sequences presented here reflecting the general evolutionary trends affecting the wheat genome as a whole.

AB:   Digoxigenin-labeled total genomic DNA from Oryza eichingeri was hybridized in situ to somatic chromosome preparations of F1, F2, backcross progenies, and a pollen-derived tetraploid plant (E24) from O. sativa (2n = 24, genome AA) X O. eichingeri (2n = 24, genome CC), which allowed a definitive discrimination between A- and C-genome chromosomes. Twelve chromosomes in F1, F2, BC1, and twenty-four chromosomes in plant E24 were clearly revealed to be of O. eichingeri origin, thus confirming that both BC1 and F2 were allotriploids (2n = 36, AAC) while plant E24 was an amphiploid (2n = 48, AACC). In addition, the presence of O. eichingeri chromosomes in four alien addition lines was characterized. The results suggest that FISH/GISH may be a powerful tool for monitoring the O. saliva-alien chromosome in the progenies of rice interspecific hybridization.

AB:   Maize streak, incited by maize streak geminivirus (MSV), is a major disease limiting maize (Zea mays L.) production over widespread areas of Africa. To understand the genetic basis of tolerance to MSV, recombinant inbred lines (RILs) derived from the cross of the MSV tolerant inbred Tzi4 with the MSV susceptible inbred Hi34, were evaluated for MSV tolerance. Experiments were conducted using controlled leafhopper (Cicadulina spp.) infestation in one glasshouse experiment at Namulonge, Uganda, and two field experiments at Centro Internacional de Mejoramiento de Maiz y Trigo, Harare, Zimbabwe. Eighty-seven RILs were genotyped at 82 loci by restriction fragment length polymorphism (RFLP) analysis. The association between genotype at RFLP marker loci and MSV tolerance was determined using single-factor analysis of variance (SFAOV), multiple regression, and interval mapping procedures. There was a significant association of MSV tolerance with RFLP markers on the short arm of chromosome 1. By SFAOV, the portion of the phenotypic variance explained by genotype class (R2) for the association between npi262 and the area under disease progress curve (AUDPC) measure of MSV tolerance was as high as 76% in field experiments. Interval mapping analyses (Knapp and Bridges 1990; Nelson 1997) identified the chromosome region bracketed by bnl12.06a and npi262 as explaining the largest proportion of the variation in MSV tolerance. After classification of symptom responses from the final field ratings into resistant and susceptible classes, qualitative analysis of data fit a chi-square test to a 1:1 Mendelian ratio, further indicating presence of a single major gene. Multipoint linkage analysis placed this gene.
       designated msv1, at a genetic distance of 3 cM distal to npi262. Identification of the tightly linked molecular marker locus npi262 should greatly aid ongoing conversion of susceptible African varieties to maize streak resistance.

AB:   Forty-eight 3.5-month-old lambs were used (2x2x2x2 factorial arrangement) to determine effects of corn and rumen undegradable protein (R) levels in growing diets on growing (56 days) and subsequent finishing (47 days) performance by lambs differing in growth potential. During the growing phase, the basal diet consisted of bermudagrass (Cynodon dactylis L.) hay (8% CP) consumed ad libitum and 0.3% BW of soybean meal. Factors investigated were: 1.0 vs 2.5% BW (LC and HC, respectively) of ground corn: 0 vs 0.5% BW (S and SR, respectively) of a mixture of fish, feather, and blood meals (36.27, and 37%, respectively): ewes vs wethers (17.9 +/- 0.63 and 19.2 +/- 0.66 kg initial BW, respectively); and Romanov (RV) x St. Croix vs Suffolk (SU) x St. Croix (18.2 +/- 0.61 and 18.7 +/- 0.63 kg initial BW, respectively). During the finishing phase, all lambs consumed ad libitum the same 80% concentrate, 20% CP diet. Dry matter intakes during growing (0.83, 0.96, 0.97, and (0.97 kg/day; SE = 0.023) and finishing (1.47, 1.67, 1.66, and 1.56 kg/day for LC-S, LC-SR, HC-S, and HC-SR, respectively; SE = 0.052) were affected by interactions (p = 0.05) between corn and R levels. Corn and R levels increased (p less than or equal to 0.02) mass of fat (4.68, 5.82, 6.25, and 7.02 kg; SE = 0.271) and protein (3.91, 4.11, 4.15, and 4.40 kg for LC-S, LC-SR, HC-S, and HC-SR, respectively; SE = 0.031) after growing, although effects, particularly those of corn level, varied with sire breed [fat: 5.49, 5.01, 6.13, and 7.15 kg (SE = 0.286): protein: 4.07, 3.06, 4.18, and 4.37 kg for RV-LC, RV-HC, SU-LC, and SU-HC, respectively (SE = 0.065)]. Dietary corn level during growing increased accretion.
       of empty BW [268, 258, 289, and 276 g/day; SE = 9.3 (p = 0.10] and fat [151, 152, 157, and 164 g/day for LC-S, LC-SR, HC-S, and HC-SR, respectively; SE = 5.9 (p = 0.08)] during finishing. In conclusion, different concentrate levels and types during growing may comparably affect growth during growing, but can have dissimilar impact on finishing performance, and such effects are more likely to vary with growth potential as affected by genotype than gender.

AB:   Three groups (I II and III) of Muzaffarnagari sheep comprising each of four sheep were fed diets containing 92:8, 50:50 and 30:70 roughage (R) and concentrate ratio. Conventional metabolic trial was followed by gaseous exchange study in open circuit respiration chamber. The carbon content of feed, feces and urine was estimated by adopting soda lime method whereas carbon loss as carbondioxide and methane was determined from gaseous exchange in respiration chamber. Nutritive value in terms of DP (%) and TDN (%) was significantly (p < 0.05) highest on 30 R:70 C (7.11 and 68.70) group followed by 50 R:50 C (6.83 and 66.0) and 92 R:8 C (5.50 and 55.8) group. Not total methane carbon, but methane carbon expressed as a percentage if intake was signifigantly lowest in group III (1.84%) followed by group II (2.07%) and group I (2.44%). Energy balance (kcal/kg W 0.75) was significantly highest in group III (43.5) whereas in group II (39.1) was not significantly different from either group III or group I (23.5). Efficiency of utilisation of ME for maintenance was 66.1%, 62.8% and 69.2% in group I, II and III, respectively. Multiple regression of ME for production on energy retained as protein and fat gave cost of protein and fat synthesis as 14.38 and 11.71 kcal/g. The result of present study indicated that 30 R:70 C is beneficial in ration of Muzaffarnagari sheep for more protein and energy retention with less methane emission.

AB:   Twelve healthy adult ewes (mean body weight 27.42 +/- 1.43 kg) were divided into three equal groups (C1, C2 and C3) following randomised block design. Animals in group C1 were fed a concentrate mixture having 35% crushed barley grain, whereas in groups C2 and C3 barley grain was replaced with wheat bran at 50% and 100% levels, respectively. Wheat straw was fed ad libitum as sole roughage to all the animals. A 6-day metabolism trial was conducted after 21 days of experimental feeding. It was observed that the replacement of barley grain even at 100% level did not adversely affect dry matter intake (DMI). Digestibilities of dry matter (DM), organic matter (OM), total carbohydrates and nitrogen free extract (NFE) were similar in groups C1 and C2, but they were significantly reduced in group C3. Digestibility of crude fibre was found to improve with the decreasing levels of grain. While level of grain did not affect crude protein (CP) digestibility and digestible CP (DCP) content in the three diets, nitrogen balance was significantly reduced in both C2 and C3. Total digestible nutrients (TDN) were 54.95%, 53.56% and 48.67% in groups C1, C2 and C3, respectively. From the results it may be deduced that the barley grain can be replaced with wheat bran up to a 50% level in the diet of adult sheep.

AB:   A metabolism trial was conducted to evaluate the effect of two direct-fed microbial cultures containing Saccharomyces cerevisiae on ruminal fermentation and digestibility. Additives were added intraruminally to obtain a similar CFU (3 x 10(8)). Twelve Suffolk sheep with ruminal cannula (29 kg BW) were assigned to a completely randomized design where treatments were control group (CG). 3 g day(-1) of Yea-Sacc(1026) (YS, 1 x 10(8) CFU g(-1)) or 0.015 g day(-1) of Levucell (LC 20 x 10(9) (CFU g(-1)). Diet was based on corn stover (66.5%), sorghum grain (23.5%), molasses (8.6%) and urea (1.4%). Ruminal pH was lower (p < 0.01) with yeast culture (CG 6.48(a), YS 6.29(b), LC 6.33(b). Molar proportion of butyrate was increased by Saccharomyces cerevisiae, being higher with Levucell than Yea-Sac(1026). Other VFA ammonia-N and protozoa population did not show treatment effects. In situ NDF degradation was not affected by treatments, although NDF digestion at 72 h tended to increase (p = 0.09) with YS. Total tract digestibility of DM, NDF and N was not affected. Neither direct-fed microbial culture containing Saccharomyces cerevisiae improved either fermentation or digestion in sheep fed a corn stover diet.

AB:   Bean yellow dwarf virus (BeYDV) and maize streak virus (MSV) belong to the geminivirus genus Mastrevirus and have host ranges confined to dicotyledonous and monocotyledonous species, respectively. To investigate viral determinants of host range specificity, chimeras were constructed by exchanging their coding and non-coding regions. BeYDV chimeras containing MSV ORF V1, ORF V2 or small intergenic region sequences, either individually or in various sequential combinations, replicated and produced virus particles in Nicotiana tabacum protoplasts. BeYDV chimeras containing MSV ORFs C1 and C2 and/or the large intergenic region were unable to replicate. None of the chimeras was able to systemically infect either N. benthamiana or maize. Complementation experiments using BeYDV chimeras containing MSV ORF V1 and/or ORF V2 suggest that expression of MSV movement protein and/or coat protein prevents BeYDV movement. The results demonstrate that factors involved in both viral DNA replication and virus movement are exclusively adapted to either monocotyledonous or dicotyledonous host backgrounds.

AB:   The vacuolar H+ -ATPase (V-ATPase) is responsible for acidifying endomembrane compartments in eukaryotic cells. Although a 100 kDa subunit is common to many V-ATPases, it is not detected in a purified and active pump from oat (Ward J.M. and Sze H. (1992) Plant Physiol. 99, 925-931). A 100 kDa subunit of the yeast V-ATPase is encoded by VPH1. Immunostaining revealed a Vph 1p-related polypeptide in oat membranes, thus the role of this polypeptide was investigated. Membrane proteins were detergent-solubilized and size-fractionated, and V-ATPase subunits were identified by immunostaining. A 100 kDa polypeptide was not associated with the fully assembled ATPase; however, it was part of an approximately 250 kDa Vo complex including subunits of 36 and 16 kDa. Immunostaining with an affinity-purified antibody against the oat 100 kDa protein confirmed that the polypeptide was part of a 250 kDa complex and that it had not degraded in the approximately 670 equal to kDa holoenzyme. Coimmunoprecipitation with a monoclonal antibody against A subunit indicated that peripheral subunits exist as assembled V1 subcomplexes in the cytosol. The free V1 subcomplex became attached to the detergent-solubilized Vo sector after mixing, as subunits of both sectors were co-precipitated by an antibody against subunit A. The absence of this polypeptide from the active enzyme suggests that, unlike the yeast V ph1p, the 100 kDa polypeptide in oat is not required for activity. Its association with the free Vo subcomplex would support a role of this protein in V-ATPase assembly and perhaps in sorting.

AB:   A recessive maize mutant disrupted in seedling development was isolated following transpositional mutagenesis with Mutator. This mutant, lilliputian (lil1), exhibits a phenotype consisting of a large primary root, extremely reduced stature, crinkly leaves and has been mapped by TB-A translocations on the short arm of chromosome 2. Comparative histological analyses revealed an increase in cell number in the mutant root and leaves, as well as an irregularity in cell shapes, suggesting that the altered morphology of fill roots and leaves is related to an uncoordinated increase in cell divisions and to a defect in division plane alignment. On the other hand, the reduced stature of the mutant plant may be ascribed to a defect in cell elongation. In situ hybridization of primary root tissues reveals higher levels of alpha-tubulin transcripts in the pericycle and in cells surrounding vascular elements in mutant rather than in wild-type tissues. These features suggest a role of the Lil1 gene in the correct functioning of microtubules. Moreover, the fact that the mutation is recognizable even in the dormant embryo and that mutant seedlings are obtained from immature (12 DAP) lil1 embryos indicates that the defect in cell division pattern accounting for the disrupted seedling morphology manifests itself even during embryo development.

AB:   GAMYB is an MYB transcription factor which is expressed in cereal aleurone cells in response to gibberellin (GA). HvGAMYB binds to the TAACAAA box of a high-pl alpha-amylase gene promoter and transcriptionally activates its expression. In this study, we examined the role of HvGAMYB in activating expression of other GA-regulated genes encoding hydrolytic enzymes. In transient expression experiments, HvGAMYB transactivated expression of reporter genes fused to a low-pl alpha-amylase gene promoter, an Ell(1-3,1-4)-beta-glucanase gene promoter and a cathepsin B-like protease promoter. HvGAMYB DNA binding specificity was determined using a PCR-based random site selection using HvGAMYB fusion protein isolated from E. coli. The deduced consensus closely resembled gibberellin response elements in alpha-amylase promoters. Functional analysis of HvGAMYB by transient expression of C terminal HvGAMYB deletions in barley aleurone cells identified two transcriptional activation domains (TADs), which function in transcriptional regulation of both high- and low-pl alpha-amylase promoters. The same TADs were identified using a heterologous yeast expression system. Together, these results indicate that HvGAMYB has two TADs. These domains are C-terminal to its DNA-binding domain.

AB:   Four natural organic fertilizers, alone or in combination with the synthetic organic fertilizer isobutylidene diurea (IBDU), were compared with IBDU alone for their effect on soil/root microbial populations associated with bermudagrass grown on a golf course putting green in southern Florida, USA. Populations of total fungi, total bacteria, fluorescent pseudomonads, Stenotrophomonas maltophlia, actinomycetes and heat-tolerant bacteria were monitored every 3 months during the 2-year study. On only one sampling date and for only one bacterial population (S. maltophilia) was a significant difference in microbial populations obtained among the fertilizer treatments. However, the S. maltophilia populations associated with the natural organic fertilizer treatments were not significantly different from the synthetic organic IBDU fertilizer treatment.

AB:   The possibility of an additional N2O emission pathway via plants was investigated in a soil-rye-grass (Lolium perenne L.) system. The N2O emission rate of the system varied between 0.8 and 13.3 mg N20-N m-2 day-1. Comparing the N20 emission rate of the system before and immediately after cutting the rye grass allowed us to calculate the contribution of the rye grass to the N2O emission from the soil-plant system. It was found that, depending on the type of fertilization and the growing period of the plants, the N20 released from the rye grass varied between 0 and 2.8 mg N2O-N m-2 day-1. N2O emission mediated by the rye grass increased towards the end of the growing period. An exponential correlation [R2=0.93, y=(8 x 10-6 x2)-(2 x 10-5 x) +0.21] was observed between the N2O emission (y) from the rye grass and its NO3--N content (x). However, it was not clear whether N2O was produced by the plants themselves or whether the rye grass served as a conduit for N20 produced in the soil.

AB:   A glasshouse experiment investigated the effects of brown planthopper feeding on the physiology of the main shoot and its indirect effects on the primary tiller with Japonica rice Nipponbare and Indica rice Taichung Native 1. Brown planthopper sucking on the main shoot reduced its height, leaf area, average photosynthetic rate of the two upper leaves, leaf and stem nitrogen content, and shoot dry weight. Nipponbare, had a lower photosynthetic rate, and lower nitrogen content of the leaf and stem of healthy plants, and was affected by BPH feeding more than TN1. With the primary tiller kept intact, the effects of brown planthopper feeding on leaf area and shoot dry weight of the main shoot were less than with the removal of the primary tiller. The results suggest that the primary tiller, not infested by the brown planthopper, translocates nutrients and assimilates into the main shoot, to reduce the effects of brown planthopper feeding on the main shoot.

AB:   The production of auxins [indoleacetic acid (IAA) and related compounds] by Azospirillum brasilense and Klebsiella pneumoniae in culture media supplemented with tryptophan was investigated. Extracts from the supernatants of cultures incubated for different periods of time were partitioned into two fractions and each fraction was analysed separately by using HPLC. The chromatography was performed by using different optimized mobile phases and corresponding standards. Both N-fixing strains produced high quantities of extracellular IAA and tryptophol. The production of both compounds increased during the stationary phase of the culture. However, very low levels of indoleacetaldehyde and indolepyruvate produced by K. pneumoniae in the exponential phase of the culture, were only recorded when the samples were analysed immediately after the extraction. In addition, the effect of different concentrations of filter-sterilized culture supernatants of both strains on the development of rice roots grown in hydroponic culture medium was studied. Addition of the optimum concentrations (6-8%) of bacterial supernatants to such hydroponic cultures increased root elongation, root surface area, root dry matter and development of lateral roots and root hairs compared to untreated roots. On the other hand, the addition of high concentrations of the supernatant (more than 10%) strongly inhibited root elongation, lateral root development, and caused root outgrowths, i.e. round nodule-like tumours.

AB:   Sorghum midge (Stenodiplosis (=Contarinia) sorghicola Coquillett) is an important pest of grain sorghum worldwide, and several sources of resistance have been identified in the world sorghum germplasm collection. DJ 6514 and the breading lines derived from it become susceptible to sorghum midge in Kenya. Therefore, we evaluated a diverse array of midge-resistant and -susceptible lines at Alupe, Kenya; and ICRISTAT Center, India, to identify lines with stable resistance across seasons and locations. The test material was also evaluated for resistance to leaf diseases at Alupe, Kenya; to identify lines with multiple resistance to sorghum midge and leaf diseases. Across seasons and locations; IS 3461, IS8884, IS 8887, IS 8891, IS 19476, IS 22806, and AF 28 showed high to moderate levels of resistance to midge, and these lines will be useful for use in resistance breeding programs. Thirty-nine lines showed resistance to midge both under natural infestation and no-choice headcage screening at ICRISTAT Center, India, over four seasons, of which IS 18696, IS 22806, ICSV, 197, ICSV 745, ICSV 88032, PM 20710-2, DJ 6514, and AF 28 were highly resistant. Genotypes IS 3461, IS 8884, IS 8887, IS 8589, IS 19476, IS 22806, ICSV 736, ICSV 90003, and AF 28 showed moderate levels of resistance to both midge and leaf diseases at Alupe, Kenya; and these lines can be used as sources of multiple resistance to these pests. Lines IS 2766, IS 7148, IS 8733, and IS 8589, showed high levels of resistance to leaf diseases in Kenya. Resistance to midge breaks down in some lines at Alupe, Kenya; possibly because of the influence of environment on the expression of resistance or the possible differences in midge populations at different.

AB:   Phalaris minor Retz. (littleseed canarygrass) is an important winter season weed of several crops across many continents. P. minor is a prolific and competitive weed especially in wheat crops. This review considers its distribution, biology and agro-ecology. Special importance is attached to considering the value and limitations of cultural and chemical control methods together with a crop management blueprint. While the use of selective herbicides is critical to maintain economic returns of wheat production, there are issues associated with their continuous use. Undoubtedly the development of herbicide-resistant biotypes of P. minor is an epidemic in India of economic, cultural and scientific importance. Consideration is given to the nature of the resistance problem and management approaches designated to minimise the impact of resistance and perhaps avoid further spread of the epidemic. Future research strategies are discussed to address the nature of this important grass weed problem. These include the importance of agronomic and physiological research to understand the basis of weed behaviour.

AB:   Traditional tree fallows have been abandoned on the western coast of the Reunion Island because of the increasing need for cultivated land. Soil fertility is no longer restored and crop yields have decreased drastically. The leguminous plant, Lotus uliginosus (trefoil), used as a cover crop, has made possible the control of erosion, the restoration of soil macrofauna, especially earthworms, and the increase in crop yields. When trefoil was associated with earthworms (Amynthas corticis), the densities of maize, the yields of maize stalk and dry matter, the yield of trefoil fodder dry matter, and the biomass and respiratory activity of soil microflora were considerably increased. The combined effects of their association led to a significant decrease in populations of the plant-parasitic nematode, Pratylenchus vulnus, in maize roots, and in the population of borers. Some soil chemical features were modified.

AB:   The role of blue-green algae (BGA) and Azolla in supplying N to rice fields is well documented. In addition, they also bring about, directly or indirectly, a number of changes in the physical, chemical and biological properties of the soil and soil-water interface in rice fields. For example, BGA liberate extracellular organic compounds and photosynthetic O2 during their growth, while Azolla prevent a rise in the pH, reduce water temperature, curb NH3 volatilisation and suppress weeds; and both of them contribute biomass. On decomposing, they influence the redox activity and result in the formation of different organic acids in soil. All such changes brought about by BGA and Azolla in soil may ultimately influence plant-available nutrients and also soil characteristics. An attempt has been made in this review to highlight these effects of BGA and Azolla in rice fields and discuss their possible implications relating to management and productivity of rice-field systems.

AB:   The composition of the fiber and CP of alfalfa, bromegrass, and endophyte-free and -infected tall fescue forages was compared during the spring growth from vegetative to reproductive stages. Forages were sampled from April 27 to June 6 in 1994, and from April 27 to June 11 in 1995, with 11 and 12 harvest dates, respectively. Total dietary fiber (TDF) was fractionated into insoluble and soluble fiber (SF). The CP of the forages was fractionated into nonprotein N (A), soluble CP (B1), insoluble CP that was soluble in neutral detergent (B2), CP insoluble in neutral detergent but soluble in acid detergent (B3), and CP insoluble in acid detergent (C). Effects of year, forage species, and harvest dates (day as a covariable) were included in the model. Across harvest dates, alfalfa (A) had lower (P < .01) TDF and higher (P < .01) SF concentrations than grasses (GR) (A: 49.9 and 14.4% and GR: 60.4 and 4.6% [OM basis] for TDF and SF, respectively). Alfalfa had higher (P < .01) CP (20.6% DM) than GR (15.3%). The rate of decrease in CP (% DM) across days was higher (P < .01) for bromegrass (-.4%/d) than for the other forages (-.29%/d). Fraction A (% of CP) was not different (P = .24) among forages (22.5%), but B1 was higher (P < .01) in A (17.1%) than in GR (13.2%). The B2 fraction (% of CP) was higher (P < .01) in A compared with GR (51.6 vs 45.9%, respectively). Alfalfa had lower (P < .01) B3 (3.0% of CP) than bromegrass (18.6%) and tall fescue (13.2%). Fraction C was not different (P = .23) among forages (3.8%). Fractions A, B1, and C (% of CP) did not change (P > .05) across days for all forages. Fraction B2 (% of CP) decreased across days in A (-.21%/d) but was not affected in GR. Fraction B3 (% of.
       CP) increased (P < .05) in A (.1%/d), decreased in endophyte-infected tall fescue (-.20%/d), and did not change (P > .05) in the other forages. Crude protein and fiber composition were affected more by forage species than by maturity. The CP and NDF concentrations were more affected by maturity. Insoluble fractions but not soluble fractions of CP were affected by maturity.

AB:   The effects of different levels of cracked corn on N intake, ruminal bacterial CP synthesis, and duodenal flows and small intestinal digestion of amino acids (AA) in steers fed fresh alfalfa indoors were determined. Angus steers (n = 6; average BW 338 +/- 19 kg) cannulated in the rumen, duodenum, and ileum were fed each of five diets over five periods in a Latin square design with an extra animal. Steers consumed 1) alfalfa (20.4% CP, 41.6% NDF) ad libitum (AALF); 2), 3), and 4) AALF supplemented (S) with three levels of corn (.4, .8, or 1.2% of BW, respectively), or 5) alfalfa restricted (RALF) to the average forage intake of S steers. Average N intake and duodenal flow of nonammonia N (NAN) were greater (P < .01) in S than in RALF steers. Greater duodenal flows of NAN in S compared with RALF were due to a trend toward higher (P = .06) flows of both bacterial and dietary N. Levels of corn decreased (P < .01) linearly N intake and increased (P < .01) linearly duodenal flow of NAN owing to a numerical linear increase in nonbacterial N (P = .15) with no increase in bacterial N flow. Duodenal NAN flows as percentages of N intake increased (P < .01) linearly (69.3 to 91.0%) as corn increased. Ruminal NH3 N concentration, ruminal CP degradability, and the proportion of bacterial N in duodenal NAN were decreased (P < .01) linearly as corn increased. Efficiency of net microbial CP synthesis was not affected (P > .05) by treatment (average 42.6 and 30.9 g N/kg of OM apparently or truly digested in the rumen, respectively). Small intestinal disappearance of total N and individual AA, except for threonine and lysine, and small intestinal digestibility of N and individual.
       AA, except for methionine, histidine, and proline, increased (P < .01) linearly with level of corn and were greater (P < .01) in S than in RALF steers. Supplementing corn to steers fed fresh alfalfa reduced ruminal N losses and CP degradability and increased the duodenal flow and the small intestinal disappearance and digestibility of total N and total, essential, and nonessential AA.

AB:   The effect of supplementation with different levels of cracked corn on the sites of OM, total dietary fiber (TDF), ADF, and starch digestion in steers fed fresh alfalfa indoors was determined. Six Angus steers (338 +/- 19 kg) fitted with cannulas in the rumen, duodenum, and ileum consumed 1) alfalfa (20.4% CP, 41.6% NDF) ad libitum (AALF); 2), 3), and 4) AALF supplemented (S) with .4, .8, or 1.2%, respectively, of BW of corn; or 5) alfalfa restricted at the average level of forage intake of S steers (RALF), in a 5 X 5 Latin square design. Total OM intake was lower (P < .01) in steers fed RALF than in those fed AALF but level of forage intake did not affect sites of OM, TDF, or starch digestion (P > .05). Forage OM intake decreased (P < .01) linearly (8,496 to 5,840 g/d) but total OM intake increased (P = .03) linearly (8,496 to 9,344 g/d) as corn increased from .4 to 1.2% BW. Ruminal apparent and true OM disappearance was not affected, but OM disappearing in the small intestine increased (P < .01) linearly with increasing levels of corn. Total tract OM digestibility (71.2 to 76.2%) and the proportion of OM intake that was digested in the small intestine (15.4 to 24.5%) increased (P < .01) linearly as corn increased. The TDF and ADF intakes decreased (P < .01) linearly as level of corn increased. Total tract TDF and ADF digestibilities were not different among treatments (average 62.9 and 57.8%, respectively). Starch intake and starch digested in the rumen and small and large intestine increased (P < .01) linearly with increasing corn level. Ruminal pH and VFA concentrations decreased and increased (P < .01), respectively, with increasing corn. Supplementation with corn increased OM intake.
       decreased forage OM intake, and increased the proportion of OM that was digested in the small intestine, but fiber digestion was not affected.

AB:   Host plant switching by dispersing early instar lepidopterans could have implications for parasitoid performance, but this possibility has not been evaluated thoroughly. The relative growth rates of Lymantria dispar parasitized by Cotesia melanoscela, and the weight of larvae at the time of parasitoid emergence, were affected most by the second larval food plant consumed. The relative growth rates, pupal weights, weight of larva at the time of parasitoid emergence, and development times of L. dispar were affected significantly by the second larval food plant consumed. Development time and size of Cotesia melanoscela were affected most by the second larval food plant consumed. Parasitoid performance was affected most by the larval host's relative growth rate and the final weight of the host larva at the time of parasitoid emergence. Host plant switching affected the weight of L. dispar larvae at the time of parasitoid emergence, but the effect of switching per se was not a significant factor in C. melanoscela size or development. Lymantria dispar larvae that fed on Populus as their second host outperformed larvae that fed ultimately on Acer. Parasitoids yielded from L. dispar larvae that fed ultimately on Populus outperformed parasitoids yielded from larvae that fed ultimately on Acer. Per cent mortality of L. dispar due to parasitism and percentage adult C. melanoscela emergence were highest in parasitized larvae fed Populus, poor in hosts fed Acer, and intermediate in switching larvae.

AB:   Eleven aluminum stress-induced genes derived from plants (wheat, Arabidopsis and tobacco) were introduced into Saccharomyces cerevisiae to test if expression of these genes confers Al tolerance. Al sensitivity tests showed that expression of two genes, either an Arabidopsis gene for blue copper binding protein (BCB), or a tobacco gene for the GDP dissociation inhibitor (NtGDIl), conferred Al tolerance. Determinations of total content and localization of Al ions in these transformants suggested that the BCB gene product functions in restricting Al uptake, while expression of the NtGDIl gene promotes release of Al ions after uptake.

AB:   Two plant-growth-promoting bacteria, Azospirillum brasilense Cd and Pseudomonas fluorescens 313, immobilized in 1983 in two types of alginate-bead inoculant (with and without skim-milk supplement) and later dried and stored at ambient temperature for 14 years, were recovered in 1996. The population in each type of bead had decreased, yet significant numbers survived (10(5)-10(6) cfu/g beads). Population numbers depended on the bead type and the three independent bacterial counting methods: the conventional platecount method, indirect enzyme-linked immunosorbent assay and the limited-enrichment technique. Both bacterial species retained several of their original physiological features. When inoculated onto wheat plants, both species colonized and produced plant-growth effects equal to those of the contemporary strain from a culture collection or to their own 1983 records. This study showed that bacteria can survive in alginate inoculant over long periods.

AB:   To improve the economic competitiveness of the acetone/butanol/ethanol fermentation process, glucose/corn steep water (CSW) medium was used on a pilot scale for the production of solvents. The production of butanol by the Clostridium beijerinckii NCIMB 8052 parent strain and the solvent-hyperproducing BA101 mutant was compared. In a 20-l fermentation using 5% glucose/CSW medium, C. beijerinckii 8052 produced 8.5 g butanol/l and 5 g acetone/l, while C. beijerinckii BA101 produced 16 g butanol/l and 7.5 g acetone/l. Further studies were carried out on a larger scale using an optimized 6% glucose/CSW medium. In a 200-l pilot-scale fermentor, C. beijerinckii 8052 produced 12.7 g butanol/l and 6 g acetone/l following 96 h of fermentation. C. beijerinckii BA101 produced 17.8 g/l and 5.5 g/l butanol and acetone respectively, following 130 h of fermentation. These results represent a 40% increase in final butanol concentration by the C. beijerinckii BA101 mutant strain when compared to the 8052 parent strain. The total solvents (acetone, butanol, and ethanol) produced by C. beijerinckii NCIMB 8052 and BA101 in a 200-l fermentation were 19.2 g/l and 23.6 g/l respectively. This is the first report of pilot-scale butanol production by the solvent-hyperproducing C. beijerinckii BA101 mutant employing an inexpensive glucose/CSW medium.

AB:   The basidiomycetous yeast Rhodosporidium toruloides (anamorph, Rhodotorula glutinis) is a common phylloplane epiphyte with biocontrol potential. To understand how R. toruloides adheres to plant surfaces, we obtained nonadherent fungal mutants after chemical mutagenesis with methane-sulfonic acid ethyl ester. Sixteen attachment-minus (Att-) mutants were identified by three methods: (i) screening capsule-minus colonies for loss of adhesive ability; (ii) enrichment for mutants unable to attach to polystyrene; and (iii) selection for reduced fluorescence of fluorescein isothiocyanate-concanavalin A (Con A)-stained cells by fluorescence-activated cell sorting. None of the 16 mutants attached to polystyrene or barley leaves. The lectin Con A eliminated adhesion in all of the wild-type isolates tested. Hapten competition assays indicated that Con A bound to mannose residues on the cell surface. Adhesion of wild-type R. toruloides was transient; nonadhesive cells subsequently became adhesive, with bud development. All Att- mutants and nonattaching wild-type cells lacked polar regions that stained intensely with fluorescein isothiocyanate-Con A and India ink. Lectin, enzyme, and chemical treatments showed that the polar regions consisted of alkali-soluble materials, including mannose residues. Tunicamycin treatment reduced wild-type adhesion, indicating that the mannose residues could be associated with glycoproteins. We concluded that compounds, including mannose residues, that are localized at sites of bud development mediate adhesion of R. toruloides to both polystyrene and barley leaf surfaces.

AB:   The notabilis (not) mutant of tomato has a wilty phenotype due to a deficiency in the levels of the plant hormone abscisic acid (ABA). The mutant appears to have a defect in a key control step in ABA biosynthesis--the oxidative cleavage of a 9-cis xanthophyll precursor to form the C15 intermediate, xanthoxin. A maize mutant, viviparous 14 (vp14) was recently obtained by transposon mutagenesis. This maize genetic lesion also affects the oxidative cleavage step in ABA synthesis. Degenerate primers for PCR, based on the VP14 predicted amino acid sequence, have been used to provide probes for screening a wilt-related tomato cDNA library. A full-length cDNA clone was identified which is specific to the not gene locus. The ORFs of the tomato cDNA and maize Vp14 are very similar, apart from parts of their N-terminal sequences. The not mutation has been characterized at the DNA level. A specific A/T base pair deletion of the coding sequence has resulted in a frameshift mutation, indicating that not is a null mutant. This observation is discussed in connection with the relatively mild phenotype exhibited by not mutant homozygotes.

AB:   In 1997, leaf rust of wheat (Triticum aestivum), caused by Puccinia triticina, was widespread throughout the prairies of western Canada. Warm summer temperatures with frequent dew periods favored spread of the disease in wheat fields in Manitoba, Saskatchewan, and Alberta. The leaf rust epidemic of 1997 was the most widespread and severe in western Canada since 1991. The Canada Prairie Spring wheat cultivars (AC Vista, AC Foremost, AC Crystal) were susceptible to leaf rust, while the bread wheats (AC Domain, AC Barrie, AC Cora, AC Majestic) were more resistant. Forty-seven virulence phenotypes of leaf rust were described in 1997 using 16 near-isogenic differential lines of Thatcher wheat. Phenotypes with virulence to Lr16 comprised 16% of the isolates in Manitoba and Saskatchewan in 1997. Many recently released Canadian spring wheats have Lr16 in addition to adult plant resistance genes. Thirty-three isolates also were tested for virulence to plants with adult plant resistance genes Lr12, Lr13, Lr34, and Lr13,34. Most isolates were virulent to genes Lr12 and Lr13. All isolates had lower infection types on lines with Lr34 compared with the susceptible line Thatcher.

AB:   Simple sequence repeat (SSR)-based genetic markers are being actively developed for the majority of crop plant species. In barley, characterization of 290 dinucleotide repeat-containing clones from SSR-enriched libraries has revealed that a high percentage are associated with cereal retrotransposon-like and other dispersed repetitive elements. Associations found were with BARE-1, WIS2-1A, PREM1 and the dispersed repetitive element R173. Additional similarities between different SSR clones, which have no matches in DNA sequence databases, indicate that this phenomenon is probably widespread in the barley genome. Sequence homologies to the non-coding regions of several cereal genes were also explained by homology to mobile genetic elements. The SSRs found can therefore be classified into two types: (1) those with unique sequences on either flank, and (2) those which are intimately associated with retro-transposons and other dispersed repetitive elements. As the cereal genome is thought to consist largely of this type of DNA, some random association would be expected. However, the conserved positions of the SSRs, relative to repetitive elements, indicate that they have arisen non-randomly. Furthermore, this class of SSRs can be classified into three subtypes: (1) those which are positioned 3' of a transposable element with unique sequence on the other flank, (2) those positioned 5' of a transposable element, and (3) those which have arisen from an internal sequence and so have transposable element sequence on both flanks. The first appear to be analogous to the class of SSRs in mammalian systems which are associated with Alu elements and SINEs (short interspersed elements).
       and which have been postulated to arise following integration of an extended and polyadenylated retro-transcript into the host genome, followed by mutation of the poly(A) tract and expansion into an SSR. For the second, we postulate that a proto-SSR (A-rich sequence) has acted as a 'landing pad' for transposable element insertion (rather than being the result of insertion), while the third includes those which have evolved as a component of an active transposable element which has spread throughout the genome during bursts of transposition activity. The implications of these associations for genome and SSR evolution in barley are discussed.

AB:   Gibberella ear rot has increased in prevalence recently on late-season processing sweet corn grown in the Midwestern United States. Little information is available about the reactions of hybrids currently grown for processing. A total of 52 processing hybrids were evaluated in 1996 and 1997 for reactions to Gibberella zeae following one of two methods of inoculation: inserting an infested toothpick or injecting a spore suspension in the silk channel 7 days after the mid-silk growth stage. Ratings of ear rot severity ranged from 2.4 to 8 on a scale of 1 to 9. Severity of ear rot differed among hybrids, but none of the hybrids was highly resistant nor did the hybrids display a great degree of variation for reaction to G. zeae. Severity of ear rot was consistently lower for cvs. Sprint and HMX 5372 than for the other hybrids. Ear rot ratings also were lower for cvs. GH 1834 and GH 2690 in three of four comparisons. Severity of ear rot was consistently higher for cv. GH 2628 in all comparisons and for cvs. Empire, Excalibur, GG 42, GH 1861, Jubilee, Rival, and WSS 3680 in three of four comparisons. Ranks of some hybrids changed between inoculation methods, years, or both, but most hybrids were ranked similarly in at least three of four comparisons. Coefficients of variation were approximately 5% higher for the injection method of inoculation in 1996 than for the other trials. The toothpick method of inoculation required less labor and ranked hybrids as consistently or more consistently than the injection method.

AB:   Symptoms of Fusarium head blight on diseased wild rice seed from both cultivated fields and natural stands are shrunken, light weight seeds discolored light tan to light brown with infrequent light pink due to mycelial growth of Fusarium spp. F. graminearum was the predominant species isolated from whole seed at all growth stages, and from shattered seed gathered from four fields in 1994 to 1995. F. anthophilum and F. subglutinans were also frequently isolated at most growth stages, whereas F. acuminatum, F. culmorum, F. solani, and F. semitectum were infrequently isolated at one or more growth stages, and F. camptoceras was isolated only from shattered seed. F. graminearum was the only species isolated from processed seed, although rarely. Fusarium spp. were isolated at the highest percentage from shattered seed. The highest percentage of total Fusarium spp. isolated during seed development was at the milk and dough stages in a cultivated field and at the milk stage in a natural stand; the percentage then declined until the ripe stage in seed from both sites. There were no significant differences in the percentages of Fusarium spp. isolated at growth stages between seed from the cultivated field and from the natural stand. Fusarium spp. were isolated most frequently from whole seed grown in three cultivated fields, compared with the palea and lemma, and caryopsis. F. graminearum and F. anthophilum were frequently isolated from whole seed and all seed structures, whereas F. culmorum and F. sporotrichioides were isolated only from whole seed, F. moniliforme from whole seed, palea and lemma, and caryopsis, and F. subglutinans from whole seed and the palea and lemma only. Deoxynivalenol and.
       nivalenol were identified in three isolates of F. graminearum; however, none of the seed samples from which the isolates were obtained yielded either mycotoxin. Survival of Fusarium spp. in diseased seed was similar from both cultivated and natural sources and occurs in whole seed not immersed in water but not in seed immersed in water. Survival was better in seed stored at 4 degrees C than at -20 degrees C. F. graminearum was reisolated from 81% of seed from inoculated plants but not from seed of noninoculated plants. Pathogenicity of other Fusarium spp. remains to be demonstrated.

AB:   The influence of various crop rotations on population densities of Pythium spp. and Rhizoctonia solani, subsequent carrot yields, and incidence of carrot root dieback was investigated. Carrots followed crops of alfalfa, barley, carrots, cotton, onions, or fallowed soil in two independent trials. Populations of Pythium spp. were greater following alfalfa and barley than other crops in one of the 2 years of the study. Populations of R. solani were generally greater following alfalfa and cotton than other crops in each of the 2 years of the study. In 1 year, yields of marketable carrots were reduced following the alfalfa crop; no other cropping pattern influenced carrot yields. The incidence of root dieback, which resulted in mature carrots with misshapen or multiple taproots, was generally greater following alfalfa and barley than other crops in one trial, and greater following alfalfa and cotton in the other trial.

AB:   Maize hybrids genetically engineered with genes from the bacterium Bacillus thuringiensis (Bt maize) express CryIA(b) and other Cry proteins that are toxic to certain insects, particularly the European corn borer (Ostrinia nubilalis). Maize kernel feeding by O. nubilalis often leads to infection by fungi in the genus Fusarium, including the fumonisin-producing species F. verticillioides and F. proliferatum. In field experiments in 1995, 1996, and 1997, transgenic maize hybrids and near-isogenic, nontransgenic hybrids were manually infested with neonatal European corn borer larvae. Manual infestation increased Fusarium ear rot severity and fumonisin concentrations in kernels of nontransgenic hybrids. Transgenic hybrids with kernel expression of CryIA(b) consistently experienced less insect feeding on kernels and less Fusarium ear rot than their nontransgenic counterparts. In manually infested treatments, these hybrids also exhibited lower concentrations of fumonisins in kernels compared with their nontransgenic counterparts. In manually infested treatments in 1995, mean fumonisin B1 concentrations were 8.8 microgram/g in the nontransgenic hybrid and 6.7 or 3.0 microgram/g in transgenic hybrids. In 1996, mean fumonisin B1 concentrations in manually infested treatments were 4.9 microgram/g (range 2.3 to 8.8) for nontransgenic and 1.2 microgram/g (range 1.0 to 1.3) for transgenic hybrids with kernel expression. Mean total fumonisin concentrations (fumonisin B1 + B2 + B3) were 7.0 microgram/g (range 3.0 to 12.2) for nontransgenic and 1.7 microgram/g (range 1.5 to 1.9) for transgenic hybrids with kernel expression. In 1997, mean fumonisin B1 concentrations in manually infested.
       treatments were 11.8 microgram/g (range 7.6 to 17.3) for nontransgenic and 1.3 microgram/g (range 0.8 to 2.2) for transgenic hybrids with kernel expression of CryIA(b) or Cry9C. Mean total fumonisin concentrations were 16.5 microgram/g (range 10.7 to 24.0) for nontransgenic and 2.1 microgram/g (range 1.5 to 3.1) for transgenic hybrids with kernel expression. Transgenic hybrids that do not express CryIA(b) or Cry9C in kernels did not consistently have fumonisin concentrations different from the nontransgenic hybrids. Higher fumonisin concentrations in nontransgenic hybrids were associated with high European corn borer populations during the early reproductive stages of the maize plants. These results indicate that under some conditions, genetic engineering of maize for insect resistance may enhance its safety for animal and human consumption.

AB:   The combined effects of rotation crops and nitrogen fertilizers were examined on the strawberry black root rot disease complex. In July 1995, microplots were filled with soil that had a history of strawberry black root rot and seeded with two types of oats (Avena strigosa 'Saia oats' or A. sativa 'Garry oats') or with sorgho-sudangrass (Sorghum bicolor x S. sudanense 'Triple S'). Microplots planted with 1-year-old 'Honeoye' strawberry crowns served as the controls. In May 1996, the crops were chopped and incorporated into the soil. The soil was re-planted with 1-year-old strawberry 'Honeoye' crowns and then fertilized with (NH4)2SO4 or Ca(NO3)2 at equivalent rates of N. Two months later, (NH4)2SO4-treated plants had 36% more leaf area and 41% more runners than strawberries treated with Ca(NO3)2. Strawberries that had been precropped with 'Saia' oats had 135% more runners and 38% more early fruit yield than strawberries grown in control microplots. Total fruit yield was not affected by the treatments. Compared to Ca(NO3)2, the (NH4)2SO4 treatment reduced the percentage of blackened roots. The influence of the cover crops on growth and disease was stronger with (NH4)2SO4 fertilization than with Ca(NO3)2 fertilization. Combining 'Saia' oats or sorghum-sudangrass rotation with (NH4)2SO4 fertilization reduced lesion nematode (Pratylenchus penetrans) numbers in subsequent strawberry roots when compared to controls. Also, the combination of 'Saia' or 'Garry' oats as a precrop with applications of (NH4)2SO4 reduced black root rot severity when compared to controls. Only the 'Garry' oat rotation reduced strawberry root colonization by Rhizoctonia fragariae when compared to controls. Other.
       effects were associated with using (NH4)2SO4. The (NH4)2SO4 treatment lowered the rhizosphere soil pH by 0.2 units, reduced the numbers of fluorescent pseudomonads in the rhizosphere by 10- to 15-fold, and produced leaves that had more N, K, S, Mn, and Zn content than plants treated with Ca(NO3)2. Rotation with 'Saia' oats combined with (NH4)2SO4 fertilization may suppress strawberry black root rot and increase yields through multiple effects on the host, pathogens, and associated microflora.

AB:   One hundred twenty-four bacterial isolates originating from sweet corn or corn flea beetles in the northeastern, midwestern, and mid-Atlantic United States were verified as Erwinia stewartii (Pantoea stewartii subsp. stewartii) and characterized phenotypically by their respiratory response to 91 carbon sources. The unweighted pair group method of averages (UPGMA) was used to construct a dendrogram that revealed homogeneous metabolic profiles at 93% similarity. Two-thirds of the isolates formed 18 separate groups, each sharing the same metabolic profile. One-third of the isolates had distinct metabolic profiles. Most groups shared either isolation source, geographical location, and/or year of isolation. Members of some groups persisted through time and had been isolated from diverse geographical locations. Four representative strains of the proposed Pantoea stewartii subsp. indologenes were also characterized; their metabolic profiles were most similar to those of Erwinia herbicola (Pantoea agglomerans).

AB:   Forage production is reduced in saline environments in the pampean grasslands, so search for tolerant germplasm is needed. Seed from 56 naturalized populations of Italian ryegrass (Lolium multiflorum Lam.) was collected from grasslands of different agro-climatic districts of the Buenos Aires province (Argentina). These populations and three cultivars were screened for germination under saline conditions and to establish population affinities associated with the germination behaviour. A germination trial was conducted utilizing NaCl solutions with electrical conductivities of 0; 2 and 6 dSm-1. The interaction between entries and NaCl levels was not significant but there were differences among entries for all the characters analyzed. Only the mortality and the germination index were not affected by the increasing conductivity of the incubation media. The 'genetic determination grade' and relative performance of entries for the variables vigour, standard germination and dormancy also were calculated. Cluster analysis was performed and four groups were defined according to the germination behaviour of the accessions under the different NaCl levels. Using the germination traits analyzed, we detected variability in the naturalized populations of Italian ryegrass for salt tolerance.

AB:   Regional rye populations and wheat cultivars/lines were screened for aluminum tolerance using the hematoxylin staining method. Portuguese regional rye populations showed better tolerance than the Polish cv. Dank. Zlote, used as tolerant tester. In the group of bread wheats, EPM 305/81, a Barbela reselection, was the most tolerant genotype with the same behaviour as the cv. BH 1146, a tolerant tester. In a study with lines selected from a local Barbela landrace, aluminum tolerance variability was detected. Some lines were as tolerant, or higher, as wheat tester. As Portuguese rye populations and the Barbela wheat landrace have grown for centuries on an acid soil region, the data supports the idea that natural biotic or abiotic stresses associated to man selection, lead to the adaptation of genotypes to specific regional conditions and, in this case, to acid soils where aluminum toxicity occurs.

AB:   Molecular diversity in Saccharum complex was studied using 195 RAPD markers generated by 12 random primers. Among the Saccharum species, S. officinarum showed a low level of genetic diversity while S. sinense was found to be more diverse. Six taxonomical groups were clearly resolved in the cluster analysis. S. officinarum, S. robustum, S. spontaneum and Erianthus spp. formed discrete groups. S. barberi and S. sinense formed a single cluster, so also Narenga and Sclerostachya. S. officinarum was found to be closer to S. robustum and distant from S. spontaneum. Among the related genera, Sclerostachya was closer to Saccharum while Erianthus was found to be highly divergent from all the Saccharum species. Six of the primers used generated RAPD fragments unique to Erianthus. It is suggested that the Erianthus spp. can contribute substantially towards sugarcane varietal improvement in view of its greater divergence with Saccharum.

AB:   Several different methods using different numbers of plants and observations have been used for characterisation of germplasm. In this study, two different observation strategies for characterisation were tested in order to determine the minimum number of observations and plants per accession whilst still obtaining accurate results using eight forage legume species, eight forage grass species multiplied from seeds and eight clonally propagated forage grass species. In most cases, 10 observations, with 1 observation per plant would be sufficient to reach an acceptable error percentage. Observations taken on a plant basis with one observation per plant appears to be the most efficient way of scoring morphological characters. If less than 10 plants per accession are available, the reduced number of plants can be compensated by taking more observations per plant. An acceptable error percentage can often not be reached when the number of plants is less than four or five, even if many observations per plant are taken.

AB:   Large areas of wheat (Triticum aestivum L. Fion et Paol.) are grown under above-optimal temperatures causing significant yield reductions. Adaptation of wheat to such areas through genetic improvement is a way of increasing production in those regions. To identify new and novel sources of heat tolerance, 2,255 Mexican wheat landraces, grown for seed regeneration under semi-controlled conditions in the screenhouse, were evaluated for leaf chlorophyll content (LCC). The landraces were collected from areas with seasonal high temperatures. Based on these initial results, two subgroups of 127 landraces each were selected, one with high LCC values and one with low LCC values. During 1997 the selected subgroups were grown in the screenhouse and in field trials in Cd. Obregon, Mexico. The landraces were evaluated for traits associated with heat tolerance: LCC, canopy temperature depression, and thousand-kernel weight (KWT). The objectives of the study were to identify new sources of heat tolerance and to assess the feasibility of combining basic seed regeneration with characterization for needed traits like heat tolerance. A highly significant correlation was found between LCC in the screenhouse and in field trials, indicating the promise of using a screenhouse for cost effective evaluation of heat tolerance traits. This strategy could be used to identify regions or groups of germplasm that merit more intense screening. Highly significant correlations were also found between LCC and KWT. Three landrace cultivars with superior and consistent LCC values were identified. These accessions are potentially useful sources for improving heat tolerance in cultivated wheat.

AB:   In a backcrossing program to introduce the wx (glutinous endosperm) gene from a Thai upland rice cultivar, Col.No.15, to a Japanese cultivar, Sasanishiki, of Asian cultivated rice, Oryza sativa L., weak plants were observed in the BC1F1 generation. These weak plants were characterized by poor growth and discoloration at the tillering stage, though they were completely fertile. Hybrid breakdown, which is defined as hybrid weakness and sterility detected in the F2 and later inbred generations of varietal crosses, is controlled by a pair of recessive genes, hwd1 and hwd2, at unlinked loci. Two dominant genes at either the same or different loci, Hwd1/Hwd1 hwd2/hwd2, hwd1/hwd1 Hwd2/Hwd2 or Hwd1/hwd1 Hwd2/hwd2, are needed for normal growth. Using tester lines homozygous for a pair of recessive genes selected in the BC1F3 generation, the genotypes for hybrid breakdown of 100 Asian rice cultivars were determined based on the phenotype of F1 plants. Clinal variation for hybrid breakdown was observed. Cultivars with two dominant alleles at either hwd1 or hwd2 locus, were mainly found in insular Asia (Japan, Philippines and Indonesia), while the frequency of cultivars with four dominant alleles was more common in cultivars from continental Asia. Roles of hybrid breakdown in genetic differentiation of Asian cultivated rice are discussed.

AB:   Heart disease is the leading cause of death in the U.S. One way to reduce the risk of developing the disease is to lower serum cholesterol levels by making dietary changes. In addition to reducing intake of total fat, saturated fat, and dietary cholesterol, serum cholesterol can be further reduced by added fiber, especially from sources rich in beta-glucan. In this review, two sources of beta-glucan are described; one source is oats and the other yeast. Their chemical structures and physical properties are compared, and their effect on serum lipid levels is described. Oat beta-glucans are found in various breakfast cereals and snacks. Usually, several servings of these products are required to meet the Food and Drug Administration's claim of reducing the risk of heart disease. The yeast-derived fiber is a more concentrated source of beta-glucan than the oat product. It is currently being tested in a wide variety of food products.

An intact cyclopentanone ring as well as a pentenyl side chain exhibiting only minor alterations are necessary for this activity. The (-)-enantiomeric and the (+)-7-iso-enantiomeric structure increase activity of jasmonoyl compounds.

AB:   In west Asia, it is traditional for sheep to gain body condition when low-cost native pastures are available and to mobilize reserves thus built up at other times. With diminishing shares of native pasture, crop by-products and food grains are increasing in sheep diets, and facilitate feeding for constant body condition. In a 2 X 2 X 2 factorial experiment, 48 Awassi ewes were individually fed indoors, nursed single lambs for 42 days, and were hand-milked from day 29 after lambing. Dietary treatments were imposed at different times: level of feeding (i) in the last 24 days of pregnancy P(const) v. P(mob)), (ii) in days 18 to 60 after lambing (L(const) v. L(mob)), and (iii) level of fibre in days 60 to 102 after lambing (F(high) v. F(low)). Rations P(const), L(const), F(low) and F(high) were calculated to maintain body condition. F(high) provided the calculated maximum ingestible quantity of barley straw and F(low) provided 0.08 kg barley straw per kg diet. Live weights (M) of ewes and lambs, milk yield and milk quality were recorded. With P(const), and P(mob) (0.51 and 0.33 MJ metabolizable energy (ME) per kg M(0.75) per day), M gains were 140 and 23 g/day (P < 0.001). Lamb birth mass and subsequent maternal milk yield were not affected. With L(const) and L(mob) (0.81 and 0.61 MJ ME per kg M(0.75) per day), M changes were -28 and -70 g/day (P < 0.001) and milk yields (calculated in part from lamb growth) were 1042 and 892 g/day (P < 0.01). F(high) and F(low) (385 and 170 g acid-detergent fibre per kg dry matter) were compared in a two-period change-over design experiment. Milk yields were similar (414 and 427 g/day), milk fat concentrations were 64.8 and 72.9.
       g/kg (P < 0.001) and milk fat yields were 26.5 and 31.1 g/day (P < 0.001) but solids-not-fat and protein yields were not affected. There were benefits and costs in manipulating body reserves in Awassi sheep. M at lambing affects milk yield and body condition around mating is known to improve lambing rate. The existence of body reserves also allows body condition to be lost in late pregnancy and early lactation without affecting health or apparent welfare, which simplifies management of pregnant ewes, permits feeding of milk-fat-increasing high-fibre diets but the ME to maintain increased body reserves must not be ignored.

AB:   The disappearance of neutral-detergent fibre (NDF) from six fibrous foods (lucerne hay, NaOH-treated barley straw, olive leaves, paprika meal, soya-bean hulls and sunflower hulls) when incubated in the rumen of sheep in nylon bags was investigated. Source of fibre, time of incubation and its interaction had a significant (P < 0.001) effect on NDF degradation. Stepwise regression analysis showed that the best single predictor for NDF degradation rate was the hemicellulose fraction of NDF (HEM(ndf)). The variables selected to predict potential degradability and degradability of NDF at 72 h were the proportions of acid-detergent lignin in NDF (ADL(ndf), first step) and of acid-detergent cutin in ADL (ADC(adl), second step). For NDF degradability at 12 h, the variables selected were the proportions of HEM(ndf), ADL(ndf) and ADC(adl), in the first, second and third step, respectively. The results showed that ADC is an important component to understand NDF degradability at both 12 and 72 h.

AB:   A 28-day experiment with 12 9-month-old cattle (275 kg initial weight, M1), used a 2 X 2 arrangement of treatments to compare the effect of doubling the ad-libitum quantity of long barley straw offered daily (25 or 50 g dry matter (DM) per kg M1) and sex/genotype (Limousin X Friesian steers or Friesian heifers) on intake and selection. All animals received a protein concentrate at 20 g DM per kg M1(0.75) per day. Prior to the experiment the cattle had grazed for 6 months and were given no pre-experimental change-over period. On day 1 animals were weighed (M1), allocated to treatment and penned individually. Animals were weighed on day 28 (M2). Doubling the amount offered did not affect straw intake (g DM per kg M3 per day; M3 = mean of M1 and M2) during days 22 to 28 (steers: 17.9, 17.2; heifers 14.3, 13.3; s.e. 0.50) but increased the proportion (g DM per kg DM offered) refused (steers: 258, 635; heifers: 412, 721; s.e. 22). During days 22 to 28, at each level of offer (25, 50), refused straw contained (g DM per kg DM) less leaf-plus-sheath than offered straw (25 g steers: 251, 430, s.e. 16.7; 50 g steers: 393, 450, s.e. 19.7; 25 g heifers: 304, 420, s.e. 7.2; 50 g heifers: 405, 446, s.e. 9.6). The sex/genotype effect on intake was attributed to differences in growth potential. Straw intakes increased significantly over the first 14 days, but there were no differences between days 15 to 21 and days 22 to 28. It is concluded that an excess-feeding strategy, involving a doubling of the ad libitum amount of barley straw offered did not result in growing cattle consuming more straw, in contrast to published results with sheep and goats. However, the cattle did show a limited ability.
       to selectively consume leaf-plus-sheath in preference to stem but the improvement in diet digestible organic content (estimated in vitro) was presumably insufficient to stimulate intake.

AB:   Meals prepared from low glucosinolate rapeseed screenings (SCREEN) and from seed which had heated during storage (HEAT) were compared against commercial rapeseed meal (COM) for feeding value. Oil, crude protein (CP) and acid-detergent insoluble nitrogen contents in SCREEN, HEAT and COM, respectively, were (g/kg): 118, 246 and 13; 227, 315 and 436; and 17, 64 and 21. In situ dry matter (DM) and protein disappearance rates, soluble protein fraction and effective rumen degradability of protein (EDCP) were lower (P < 0.05) in HEAT than in SCREEN or COM. Comparing oil-extracted meals in situ, EDCP of HEAT was lower (P < 0.05) than EDCP of SCREEN or COM but protein and DM disappearance rates of HEAT were only lower (P < 0.05) than those of SCREEN. Four isonitrogenous barley-based diets (150 g/kg CP, DM basis), containing SCREEN, HEAT, COM or COM supplemented with rapeseed oil (OIL), were given to lambs. For DM, organic matter and neutral-detergent fibre apparent digestibilities, the diets ranked SCREEN > HEAT = OIL > COM (P < 0.05). Digestion and retention of nitrogen were lower (P < 0.05) in lambs given HEAT than in lambs given other diets. Food efficiency of lambs given HEAT was improved (P < 0.05) as compared with lambs given SCREEN or COM. Dressing proportions were higher (P < 0.05) with HEAT, SCREEN and OIL diets than with COM. Other than minor changes in fatty acid composition of subcutaneous fat with HEAT and OIL, carcass traits were not altered by treatment. Feeding SCREEN or HEAT did not adversely affect animal performance or food utilization.

AB:   The objective was to elucidate the influences of two analytical methods, which employed neutral detergent or enzymes, on the digestion of carbohydrate fractions in the rumen and post-rumen of steers. Structural carbohydrates in diets and digesta were directly measured using both procedures and the contents of non-fibre carbohydrates (NFC) and non-fibre non-starch polysaccharides (NFSP) were estimated by subtracting the structural carbohydrates and other components from the organic matter. Carbohydrate sources were Italian ryegrass and rolled barley in the control diet and, in each of other three diets, Italian ryegrass and rolled barley plus either beet pulp, citrus pulp or soya-bean hulls. All diets contained similar proportions of dry matter as crude protein, structural carbohydrates and NFC but the starch proportion of the NFC was different in each diet, as follows: control (0.62), beet pulp (0.48), citrus pulp (0.30) and soya-bean hulls (0.63). Four Holstein steers with ruminal, duodenal and ileal cannulas were offered the four diets in a 4 X 4 Latin-square design. Estimated digestibilities of the structural carbohydrates in the rumen and the whole tract were greater (P < 0.01) when the detergent method was used than when the enzymatic method was used. The maximal difference in the ruminal digestion among the four diets was only 0.05 by the detergent method but 0.17 by the enzymatic method. Conversely, the digestibility of NFC in the rumen, as estimated from the detergent structural carbohydrates was less (P < 0.01) than that estimated from enzymatic structural carbohydrates with no evident differences among the four diets. Starch digestibility in the rumen was extensive for all diets but the ruminal.
       digestibility of NFSP was much lower in the control and soya-bean hull diets, especially when it was estimated using the detergent method. The duodenal flow of microbial protein was greater (P < 0.05) for the beet pulp and citrus pulp diets than for the control. The acetate concentration of the ruminal fluids ranged from 84 for the control diet to 128 mmol/l for the soya-bean hulls diet. The digestion of carbohydrate fractions and the fermentation characteristics in the rumen suggested that the enzymatic method is the more appropriate method for fractionating carbohydrates.

AB:   In Brazil, where the rock phosphates are high in impurities, no attempt has been made to evaluate the P supplying efficiency of the neutral ammonium citrate fraction (NAC) of P fertilizers, or to verify if the NAC + H2O extraction solution (AOAC) is satisfactory for estimating the P availability. To attain these objectives, a greenhouse experiment was carried out with samples of a Typic Hapludox soil. Four acidulated phosphates obtained from Brazilian raw materials were studied: monocalcium phosphate p.a. [Ca(H2PO4)2(.)H2O] was included as a standard source of P. as well as leached samples containing no water-soluble P. The fertilizers were thoroughly mixed with the whole soil in the pots or with only 1% of its volume, at the rate of 50 mg kg-1 of P, soluble in NAC + H2O. Corn plants (Zea mays, L.) were grown for 35 days and the amounts of dry matter and P accumulated in plant tops were determined. Increasing the amount of cationic impurities in the raw materials decreased the concentration of water-soluble P, NAC + H2O-soluble P and water-soluble P/NAC +H2O soluble P ratio of the fertilizers obtained. The P in the NAC fraction was not as much available to plants as in the NAC + H2O fraction or in pure MCP. The great variation found in dry matter (5.4 to 17.1 g pot-1) and in P uptake (6.3 to 22.2 mg pot-1) (indicates that the AOAC method is not an adequate index for evaluating the P availability of fertilizers with high amounts of cationic impurities.

AB:   Alfisols of the Savannas in northern Ghana have high base saturation and moderate P sorption capacities. Lateritic nodules are common, occuring in highly variable quantities at different landscape positions. Such nodules can have high P sorption capacities, and therefore effectiveness of P fertilisation may depend on landscape position. The objective of this study was to investicate the effectiveness of Togo rock phosphate (TRP), 50% acidulated TRP (PAPR) and single super phosphate (SSP) in providing and maintaining available P. Phosphorus supplying ability of soils from upper and lower slopes of three locations in northern Ghana was studied with and without fertilizer addition by repeated desorption with anion exchange resin membrane (AEM) burial in the laboratory and by measuring dry matter yield (DMY) and P uptake of sorghum for six successive greenhouse croppings. Transformations of the applied fertilizers were studied by sequential extraction. Phosphate desorbed with AEM after 38 days the DMY and the P uptake of sorghum all followed the order SSP > PAPR > TRP = control. The relative agronomic effectiveness of the PAPR was 63% of SSP. Although half the applied TRP was transformed to other forms than acid extractable apatite, this did not liberate P to the AEM. Less than 10% of the SSP was absorbed by the AEM. In the nodule-rich upper slope soils, initial availability of added P was higher, but decreased more rapidly than in lower slope soils. We attributed this to an initial 'concentration' of fertilizer in the smaller volume of soil fines followed by slow sorption into the nodules. At the upper slope, much of the TRP and PAPR were transformed to less available forms.

AB:   Sugarcane is one of the main economic resources of Guadeloupe (France). Cane grown on the island's vertisols shows nitrogen deficiency which is accentuated with each successive ratoon. This deficiency could partially explain the observed decrease in yield. The present study, based on the isotopic N method applied to different ratoons in the field, was aimed at: (i) diagnosing the problem in the crop environment itself: and (ii) quantifying the fertilizer-N balance. The results indicated that decrease in yield and N absorption by the cane was related to ratoon number. The real utilization coefficient for the fertilizer (RUC%) ranged from 6 and 34%, and a high proportion (30-40%) of fertilizer-N was immobilized in the soil (NiS%) after the annual crop cycle. The N absorbed by the cane was essentially derived from the soil. Rainfall at the beginning of (re)growth determined crop development and N supply to the crop. When the water requirements of the crop are satisfied, nitrogen supply and cane yield can be improved in two ways: (i) by increasing the efficiency of the applied N fertilizer (RUC% and NiS%): and (ii) by maintaining the soil's capacity to supply cane with N. This implies maintaining and, if necessary, upgrading the structural state of the vertisols.

AB:   The effect of the vesicular arbuscular mycorrhizal fungus (VAMF) Glomus mosseae on growth, yield and nutrients' uptake of the durum wheat variety 'Sifnos' was investigated in ten different soils. Inoculation had a positive effect on tillering, improved plant growth up to 11.6 times and increased grain yield up to 5.4 times as compared to non-inoculated plants. The thousand kernels weight was improved by up to 60%. The analysis of shoot tissue of the mycorrhizal plants showed that P concentration was increased up to 4 fold, while the K, Ca and Mg uptake was similar for both mycorrhizal and non-mycorrhizal plants. The concentrations of the trace elements Mn, Zn, Fe and Cu were lower in the mycorrhizal plants compared to that of non-inoculated ones. The P and Mg concentration of the grains produced by the inoculated plants was increased while the Ca concentration was decreased. The concentration of the heavy metals was either decreased (Mn, Fe, Co, Cr, Ni,Pb) or remained unchanged (Zn, Cu). The colonization in the roots ranged from 23 to 78%.

AB:   Incubation of oat coleoptile segments with 40 micromolars indoleacetic acid (IAA) induced a decrease of 35-60% in peroxidase activity at the cell wall compartment. Treatment with IAA also produced a similar decrease in the oxidation of NADH and IAA at the cell wall. Isoelectric focusing of ionic, covalent, and intercellular wall peroxidase fractions showed that acidic isoforms (pI 4.0-5.5) were reduced preferentially by IAA treatment. Marked differences were found between acidic and basic wall isoperoxidases in relation to their efficacy in the oxidation of IAA. A peroxidase fraction containing acidic isoforms oxidized IAA with a Vmax/S0.5 value of 2.4 x 10(-2) min-1 (.) g fw-1), 4.0 times higher than that obtained for basic peroxidase isoforms (0.6 x 10(-2) min-1 (.) g fw-1). In contrast, basic isoforms were more efficient than acidic isoperoxidases in the oxidation of coniferyl alcohol or ferulic acid with H2O2 (5.6 and 2.1 times, respectively). The levels of diferulate and lignin in the walls of oat coleoptile segments were not altered by treatment with IAA. The decrease in cell wall peroxidase activity by IAA was related more to reduced oxidative degradation of the hormone than to covalent cell wall cross-linking.

AB:   Current environmental and economic concerns have increased public and producer interest in reducing herbicide inputs through integrated weed management. A field experiment was conducted near College Station, TX, to evaluate an integrated johnsongrass [Sorghum halepense (L.) Pers.] management system in cotton (Gossypium hirsutum L.) using reduced rates of clethodim [(E,E)-(+/-)-2-[1-[[(3-chloro-2-propenyl)oxy]imino] propyl]-5-[2-(ethylthio)propyl]-3-hydroxy-2-cyclohexen-1 -one] and cultivation. Clethodim broadcast at 1.0X (140 g ha(-1)), 0.75X, or 0.5X rates with and without cultivation was compared with clethodim at the same rates in a 50% band over the row plus cultivation. Cultivation did not improve johnsongrass control or cotton yield when clethodim was broadcast. Johnsongrass control was less in 2 of 3 years and cotton yield less in 1 of 3 years in systems with clethodim banded plus cultivation compared with clethodim broadcast with no cultivation. Greater than 90% control was obtained by clethodim at the 0.5X rate applied to four- to six-leaf stage johnsongrass under good growing conditions. Control by clethodim at the 0.5X rate was reduced if application was delayed until johnsongrass had seven or more leaves. No differences in johnsongrass control or cotton yield occurred with clethodim at 0.75X or 1.0X rates. The results demonstrate that johnsongrass can be controlled and production costs reduced by timely broadcast application of clethodim at below-labeled rates.

AB:   A glasshouse study, using soil collected from two sites, was undertaken to compare how 30-day-old seedlings of canola (Brassica napus) and wheat (Triticum aestivum) utilized phosphorus (P) from freshly-applied (current) triple superphosphate (TSP), and TSP and rock phosphate [North Carolina and Queensland (Duchess) apatites] (RP) applied in field experiments 11 years previously (previous P). The P was applied to the soil surface and incorporated into the top 10 cm of soil with a rotary hoe. After application of the current P in the field, samples of the <2-mm fraction of the top 10 cm of soil were collected for the glasshouse study. Both canola and wheat produced poor yields without P but responded strongly to applied P. Regardless of the source of P (current and previous TSP, previous RP), canola required less P than wheat to produce the same percentage of the maximum yield of dried tops. For each amount of applied P, the concentration of P in dried tops was from about 30 to 120% higher for canola than wheat, indicating that canola roots were better able than wheat roots at accessing P from the soil, regardless of the source of P.

AB:   Low phosphorus (P) supply is a major limitation to pasture establishment and production in highly weathered acid soils. Previous research showed that the forage legume, Arachis pintoi, was more efficient in acquiring P from infertile acid soils than the forage grass, Brachiaria dictyoneura. The main objective of the present study was to determine whether the higher P-uptake efficiency (defined as "milligrams of P uptake in shoot biomass per unit root length") of the legume results from its greater ability to mobilize P from less available forms of phosphate (aluminum phosphate and organic P). The grass, Brachiaria dictyoneura CIAT 6133, and the legume, Arachis pintoi CIAT 17434, were grown in the greenhouse for 75 days in monoculture or in association. They were planted in large plastic containers holding either one of two acid soils of contrasting texture (sandy or clay loam) and amended with different sources of P. Four sources of P were used: di-calcium phosphate (Ca-P), aluminum phosphate (Al-P), phytic acid (organic-P), and cow manure (dung-P). Except for Al-P, which was applied at two levels (20 and 100 kg P ha-1), the other sources were applied at 20 kg P ha-1. We found greater differences in P acquisition between the grass and legume than between the two types of acid soil. Acquisition of P by the legume was markedly greater than that of the grass, regardless of the source of P. The legume accessed 205 to 220% more sparingly soluble, inorganic P from soil compared to the grass. The relationship between shoot P uptake and root length showed that the legume roots acquired more P per unit root length than did the grass roots. The superior ability of.
       the legume roots to acquire P from different P sources was associated with higher levels of inorganic P in roots. These results indicate that one reason for the success of Arachis pintoi in competing with aggressive grasses was its ability to acquire P from less available forms present in acid soils. This study also suggests that the measurement of inorganic-P levels in roots may serve as a selection method to evaluate tropical forage legumes for their adaptation to less available P sources in P-deficient acid soils.

AB:   In highly weathered acid soils, low supply of phosphorus (P), a major plant nutrient, severely limits pasture establishment and production. Previous research indicated that inherent differences in efficiencies of P acquisition and use exist between tropical forage grimes and legumes when grown in acid soils. These differences in P acquisition between grasses and legumes may result from their ability to use sources of less available P from infertile acid soils. We tested this hypothesis by conducting a greenhouse study. The main objective was to determine differences in shoot and root growth responses between the grass Brachiaria dictyoneura CIAT 6133 and the legume Arachis pintoi CIAT 17434 when grown under monoculture or in grass+legume association with different sources of inorganic and organic P. Two acid soils of contrasting texture (sandy or clay loam) were amended with different sources of P: di-calcium phosphate (Ca-P), aluminum phosphate (Al-P), phytic acid (organic-P), and cow manure (dung-P). Except for Al-P, which was applied at two rates (20 and 100 kg P ha-1), the sources were applied at 20 kg P ha-1. After 75 days of growth, shoot, and root biomass production, dry matter partitioning, leaf area production, total chlorophyll content in leaves, soluble protein in leaves, total root length, and proportion of legume roots in grass+legume association were determined. Greater differences for shoot and root growth characteristics were found between the grass and legume than between the two types of acid soil. Shoot biomass production per unit soil surface area of both species was higher with Ca-P than with Al-P, organic-P, or dung-P. With Ca-P, the grass produced.
       twice as much shoot and root biomass than did the legume. But, the legume responded to the sources of less available inorganic and organic P by extending its leaf area. Therefore, not only do wide differences exist between the grass and legume in their ability to grow on infertile acid soils amended with sources of relatively less available inorganic and organic P, but also the legume is better adapted to such soil conditions.

AB:   Grains of wheat were produced with differing zinc (Zn) or manganese (Mn) contents by culturing detached ears from anthesis onwards in solutions of four different concentrations of Zn or Mn (0.1, 1.0, 10, and 50 micromolar). After 20 days, ears were labeled with 65Zn or 54Mn at (i) the pretreatment concentrations of Zn or Mn, or (ii) at 10 micromolar Zn or Mn regardless of the pretreatment. Accumulation of Zn or Mn in the grain was greater as the pretreatment concentration of Zn or Mn increased from 1.0 to 10 micromolar, however, accumulation was less in ears cultured at 50 micromolar Zn or Mn. Accumulation of Mn in grain of different Mn status labeled at 10 micromolar Mn was similar in the 0.1, 1.0, and 10 micromolar Mn pretreatments, but accumulation in the grain pretreated at 50 micromolar Mn was reduced. In contrast, accumulation of Zn in grains of different Zn status when labeled at 10 micromolar Zn was highest in ears pretreated at 10 micromolar Zn, but substantially lower in ears of a lower Zn status (those pretreated at 0.1 or 1.0 micromolar Zn) as well as in those pretreated at 50 micromolar Zn. These results suggest that Zn-deficient grain was not a strong sink for Zn, while at high concentrations of solution Zn, a protective barrier exists preventing excessive accumulation of Zn in the grain. Proportionally more Zn was distributed to the inner pericarp and generally less to the endosperm, outer pericarp, and embryo as the Zn status of the grain increased. This work demonstrates that loading of Zn and Mn into, and distribution within, wheat grain is regulated by the nutritional status of the grain.

AB:   In soilless production systems, water quality can have a major impact on the growth of plants. It has become evident that moderately alkaline water is a problem for tobacco transplant growers in some regions of Kentucky. To determine the level of bicarbonate (HCO3-) alkalinity, which is detrimental to burley tobacco transplants, and to better understand the effect of calcium (Ca) and the interaction of HCO3- and Ca on the growth of burley tobacco transplants grown in a float system, three levels of CaCl2 (25, 75, and 125 mg L-1 Ca++) in factorial combination with five levels of HCO3- (0, 122, 244, 366, and 488 mg HCO3-L-1) were tested in nutrient solution culture. Four-week-old burley tobacco (Nicotiana tabacum L. var. KY-907) seedlings were transplanted to 18-L containers filled with aerated Hoagland's solution with the different levels of calcium and HCO3- for two weeks. High HCO3- alkalinity caused root system damage and plant growth inhibition, but did not induce iron (Fe) chlorosis. A significantly lower concentration of Zinc (Zn) was measured in the shoots as HCO3- levels in solution increased. In the presence of high calcium, plant growth was not significantly improved. No significant interaction of HCO3- and Ca on growth or nutrient uptake was observed in this study.

AB:   The effects of perennial peanut (Arachis glabrata) hay, an aged yard-waste compost (mainly woodchips), and a control treatment without amendment were determined on two population levels of root-knot (Meloidogyne arenaria) nematode over three consecutive years in field microplots. Okra (Hibiscus esculentus, susceptible to the root-knot nematode) and a rye (Secale cereale) cover crop (poor nematode host) were used in the summer and winter seasons, respectively. The organic amendment treatments affected plant growth parameters. In the first year, okra yields were greatest in peanut amended plots. Yield differences with amendment treatment diminished in the second and third years. Okra plant height, total fruit weight, and fruit number were greater with the lower population level of the root-knot nematode. Residual levels of nutrients in soil were greater where root-knot nematode levels and damage were higher and plant growth was poor. Nutrient levels affected the growth of a subsequent rye cover crop.

AB:   The horizontal and vertical distribution of the needle nematode Longidorus africanus was studied in a bermudagrass field in the Imperial Valley in southern California. A geostatistical method involving the use of semi-variograms was used to quantify the relationship between sampling distance and variation in L. africanus population levels. Semi-variance between nematode numbers from different samples was very low when samples were taken close together, increased with sampling distances up to ca. 15 m, and fluctuated around a sill value at distances greater than 15 m. At very large sampling distances the semi-variance increased further. It was concluded that patches with fairly similar numbers of L. africanus were elongated and up to 15 m long. Seasonal fluctuations over a 2-year period, in total numbers of L. africanus extracted from three depths, were large and highly correlated with soil temperature. Population densities were greatest during the summer months and lowest during the winter. Averaged over the 2-year period, L. africanus population densities increased with increasing depth. Chances for detecting this nematode are greatest in summer at depths of 60 to 90 cm.

AB:   In Humboldt and Del Norte counties of California and Curry County, Oregon, Easter lilies (Lilium longiflorum) are grown commercially in a 3 to 6-year rotation with pasture for cattle and sheep. Bulbs are sold to greenhouse operations to produce flowering plants. The lesion nematode, Pratylenchus penetrans, is a serious detriment to Easter lily production. Both soil and planting stock are often infested; typically, a dual nematicide application is used consisting of a preplant soil fumigation followed by an at-planting application of an organophosphate or carbamate. Nematicide usage has resulted in groundwater contamination. Several factors that could lead to an improved crop rotation program were examined in five field trials in Oregon. Examining the relative nematode host status of crops for feeding cattle and sheep indicated differences in host suitability among clovers and fescues that could prove useful in development of pasture mixes. Populations of P. penetrans under continuous fallow and pasture were monitored for 4 years following harvest of Easter lilies. Populations fluctuated in both situations but generally increased on pasture plants and decreased under fallow. Nematodes were still detectable at the end of 4 years of weed-free fallow. Populations of P. penetrans on Easter lilies were followed over two successive crops. Numbers in soil peaked in July and then decreased while numbers within roots continued to increase until harvest in October.

AB:   Soybean (Glycine max) yield often is limited by the phytoparasitic nematodes Meloidogyne spp. and Heterodera glycines in the southeastern United States. We studied the effects of rotation with bahiagrass (Paspalum notatum), velvetbean (Mucuna pruiens), or continuous soybean, aldicarb, and soybean cultivar on yield and population densities in two fields infested with a mixture of Meloidogyne spp. and H. glycines. Velvetbean and bahiagrass reduced population levels of both nematode species to near zero prior to planting soybean. At harvest, both nematode populations were equal in soybean following bahiagrass and continuous soybean but were lower following velvetbean. Both bahiagrass and velvetbean as previous crops were equal in producing significantly (P < 0.003) higher yield than continuous soybean. Velvetbean increased subsequent soybean yield by 98% and bahiagrass increased subsequent soybean yield by 85% as previous crops compared to continuous soybean. The major differences between the two rotation crops were yield response of the nematode-susceptible cultivars and at-harvest nematode populations. Velvetbean tended to mask genetic differences among cultivars more so than bahiagrass. Velvetbean also produced a more longterm effect on nematode populations, with numbers of both Meloidogyne spp. and H. glycines lower in soybean following velvetbean than following bahiagrass or continuous soybean.

AB:   Lester Brown's recent writings about trends in China's food consumption, production and rapidly rising import requirements and his predictions that the world is running out of potential to increase production of cereals received wide publicity in the press. They increased awareness of the problem among the public, which was stimulated by recent declines in world cereals production per capita, falling stocks and sharp rises in world market prices. This paper is an attempt on my part to extract a coherent picture of what Brown says about China and the world and examine it in the light of what we know about this country and of possible developments in the world as a whole. I make the following conclusions. 1. Brown misjudges China's potential to maintain and indeed increase cereals production because he misinterprets the data on land losses (he treats diversion of land from cereals to, mainly, other crops and aquaculture as if such land were lost to food production), he ignores new data which indicate that China has more agricultural land than reported in official statistics and his projected numbers do not account for responses on the part of producers, consumers and government policy to an increasing scarcity of products and rising prices. 2. The analogies he draws with the experiences of Japan, South Korea and Taiwan are inappropriate. 3. China will probably be a growing net importer of cereals but at levels much below those projected by Brown. 4. World production of cereals may indeed grow at a lower rate than in the long-term past (but not as low as that projected by Brown) which could be sufficient to accommodate China's growing import requirements and.
       the probable ones of other countries. 5. The world food problem is one of persistence of very low food consumption levels and high incidence of undernutrition in many developing countries, mainly in sub-Saharan Africa and South Asia. The persistence of severe food insecurity problems reflects not so much constraints in increasing food production in the world as whole but development failures (often agricultural development failures) and the persistence of poverty in certain countries.

AB:   A fairly comprehensive range of planting choices made by maize farmers in Kenya (including discrete endogenous variables creating self-selectivity) is modelled and estimated as one system of interrelated decisions. Two-stage and three-stage probit procedures are used to handle the simultaneity and self-selectivity problems. Results showed that population pressure and agroclimatic diversity are important determinants of crop intensification and planting regimes among maize farmers and further supported the importance of focusing maize research in terms of agroclimate and socio-economic domains. Shorter maturity and efficient double and multiple cropping methods are needed to increase land productivity and intensity of labour use in areas of high population pressure and bimodal rainfall, i.e. mid-altitude zones. On the other hand, technologies that would lead to increased productivity of capital and higher response to external inputs are desired for the highlands of Kenya. Access to extension and machine services, distance to the maize plot, and time of onset of the rains were also found to significantly influence the planting strategies of maize farmers.

AB:   Mitochondria are affected by low temperature during seedling establishment in maize (Zea mays L.). We evaluated the associated changes in the mitochondrial properties of populations selected for high (C4-H) and low (C4-L) germination levels at 9.5 degrees C. When seedlings of the two populations were grown at 14 degrees C (near the lower growth limit), the mitochondrial inner membranes of C4-H showed a higher percentage of 18-carbon unsaturated fatty acids, a higher fluidity, and a higher activity of cytochrome c oxidase. We found a positive relationship between these properties and the activity of a mitochondrial peroxidase, allowing C4-H to reduce lipid peroxidation relative to C4-L. The specific activity of reconstituted ATP/ADP translocase was positively associated with this peroxidase activity, suggesting that translocase activity is also affected by chilling. The level of oxidative stress and defense mechanisms are differently expressed in tolerant and susceptible populations when seedlings are grown at a temperature near the lower growth limit. Thus, the interaction between membrane lipids and cytochrome c oxidase seems to play a key role in maize chilling tolerance. Furthermore, the divergent-recurrent selection procedure apparently affects the allelic frequencies of genes controlling such an interaction.

AB:   We isolated a cDNA encoding a 568-amino acid, heat-stress-induced peptidyl prolyl isomerase belonging to the FK506-binding-protein (FKBP) family. The open reading frame encodes for a peptidyl prolyl isomerase that possesses three FKBP-12-like domains, a putative tetratricopeptide motif, and a calmodulin-binding domain. Specific antibodies showed that the open reading frame encodes a heat-induced 77-kD protein, the wheat FKBP77 (wFKBP77), which exhibits 84% identity with the wFKBP73 and 42% identity with the human FKBP59. Because of the high similarity in sequence to wFKBP73, wFKBP77 was designated as the heat-induced isoform. The wFKBP77 mRNA steady-state level was 14-fold higher at 37 degrees C than at 25 degrees C. The wFKBP77 transcript abundance was the highest in mature embryos that had imbibed and 2-d-old green shoots exposed to 37 degrees C, and decreased to 6% in 6-d-old green shoots. The transcript level returned to the level detected at 25 degrees C after recovery of the embryos for 90 min at 25 degrees C. We compared wFKBP73 and wFKBP77 with the heat-shock proteins having cognate and heat-stress-induced counterparts.

AB:   We tested the hypothesis that the degree of anisotropic expansion of plant tissues is controlled by the degree of alignment of cortical microtubules or cellulose microfibrils. Previously, for the primary root of maize (Zea mays L.), we quantified spatial profiles of expansion rate in length, radius, and circumference and the degree of growth anisotropy separately for the stele and cortex, as roots became thinner with time from germination or in response to low water potential (B.M. Liang, A.M. Dennings, R.E. Sharp, T.I. Baskin [1997] Plant Physiol 115:101-111). Here, for the same material, we quantified microtubule alignment with indirect immunofluorescence microscopy and microfibril alignment throughout the cell wall with polarized-light microscopy and from the innermost cell wall layer with electron microscopy. Throughout much of the growth zone, mean orientations of microtubules and microfibrils were transverse, consistent with their parallel alignment specifying the direction of maximal expansion rate (i.e. elongation). However, where microtubule alignment became helical, microfibrils often made helices of opposite handedness, showing that parallelism between these elements was not required for helical orientations. Finally, contrary to the hypothesis, the degree of growth anisotropy was not correlated with the degree of alignment of either microtubules or microfibrils. The mechanisms plants use to specify radial and tangential expansion rates remain uncharacterized.

AB:   We report the expression of the barley (Hordeum vulgare L.) COR (cold-regulated) gene cor14b (formerly pt59) and the accumulation of its chloroplast-localized protein product. A polyclonal antibody raised against the cor14b-encoded protein detected two chloroplast COR proteins: COR14a and COR14b. N-terminal sequencing of COR14a and expression of cor14b in Arabidopsis plants showed that COR14a is not encoded by the cor14h sequence, but it shared homology with the wheat (Triticum aestivum L.) WCS19 COR protein. The expression of cor14b was strongly impaired in the barley albino mutant a(n), suggesting the involvement of a plastidial factor in the control of gene expression. Low-level accumulation of Cor14b was induced by cold treatment in etiolated plants, although cor14b expression and protein accumulation were enhanced after a short light pulse. Light quality was a determining factor in regulating gene expression: red or blue but not far-red or green light pulses were able to promote COR14b accumulation in etiolated plants, suggesting that phytochrome and blue light photo-receptors may be involved in the control of cor14b gene expression. Maximum accumulation of COR14b was reached only when plants were grown and/or hardened under the standard photoperiod. The effect of light on the Cor14b stability was demonstrated by using transgenic Arabidopsis. These plants constitutively expressed cor14b mRNAs regardless of temperature and light conditions; nevertheless, green plants accumulated about twice as much COR14b protein as etiolated plants.

AB:   The chloroplast gene psbD encodes D2, a chlorophyll-binding protein located in the photosystem II reaction center. Transcription of psbD in higher plants involves at least three promoters, one of which is regulated by blue light. The psbD blue-light-regulated promoter (BLRP) consists of a -10 promoter element and an activating complex, AGF, that binds immediately upstream of -35. A second sequence-specific DNA-binding complex, PGTF, binds upstream of AGF between -71 and -100 in the barley (Hordeum vulgare) psbD BLRP. In this study we report that ADP-dependent phosphorylation selectively inhibits the binding of PGTF to the barley psbD BLRP. ATP at high concentrations (1-5 mM) inhibits PGTF binding, but in the presence of phosphocreatine and phosphocreatine kinase, this capacity is lost, presumably due to scavenging of ADP. ADP inhibits PGTF binding at relatively low concentrations (0.1 mM), whereas other nucleotides are unable to mediate this response. ADP-mediated inhibition of PGTF binding is reduced in the presence of the protein kinase inhibitor K252a. This and other results suggest that ADP-dependent phosphorylation of PGTF (or some associated protein) inhibits binding of PGTF to the psbD BLRP and reduces transcription. ADP-dependent phosphorylation is expected to increase in darkness in parallel with the rise in ADP levels in chloroplasts. ADP-dependent phosphorylation in chloroplasts may, therefore, in coordination, inactivate enzymes involved in carbon assimilation, protein synthesis, and transcription during diurnal light/dark cycles.

AB:   The semidominant mutation Liguleless3-O (Lg3-O) causes a blade-to-sheath transformation at the midrib region of the maize (Zea mays L.) leaf. We isolated a full-length lg3 cDNA containing a knotted1-like family homeobox. Six Lg3-O partial revertant alleles caused by insertion of a Mutator (Mu) transposon and two deletion derivatives were isolated and used to verify that our knotted1-like cDNA corresponds to the LG3 message. In wild-type plants the LG3 mRNA is expressed in apical regions but is not expressed in leaves. In mutant plants harboring any of three dominant lg3 alleles (Lg3-O,-Mlg, and -347), LG3 mRNA is expressed in leaf sheath tissue, indicating that the Lg3 phenotype is due to ectopic expression of the gene. The Lg3-O revertant alleles represent two classes of Lg3 phenotypes that correlate well with the level of ectopic Lg3 expression. High levels of ectopic LG3 mRNA expression results in a severe Lg3 phenotype, whereas weak ectopic Lg3 expression results in a mild Lg3 phenotype. We propose that ectopic Lg3 expression early in leaf development causes the blade-to-sheath transformation, but the level of expression determines the extent of the transformation.

AB:   Four cDNAs, one encoding an alpha-subunit and three encoding beta-subunits of the mitochondrial pyruvate dehydrogenase, were isolated from maize (Zea mays L.) libraries. The deduced amino acid sequences of both alpha- and beta-subunits are approximately 80% identical with Arabidopsis and pea (Pisum sativum L.) homologs. The mature N terminus was determined for the beta-subunit by microsequencing the protein purified from etiolated maize shoot mitochondria and was resolved by two-dimensional gel electrophoresis. This single isoelectric species comprised multiple isoforms. Both alpha- and beta-subunits are encoded by multigene families in maize, as determined by Southern-blot analyses. RNA transcripts for both alpha- and beta-subunits were more abundant in roots than in young leaves or etiolated shoots. Pyruvate dehydrogenase activity was also higher in roots (5-fold) compared with etiolated shoots and leaves. Both subunits were present at similar levels in all tissues examined, indicating coordinated gene regulation. The protein levels were highest in heterotrophic organs and in pollen, which contained about 2-fold more protein than any other organ examined. The relative abundance of these proteins in nonphotosynthetic tissues may reflect a high cellular content of mitochondria, a high level of respiratory activity, or an extra plastidial requirement for acetate.

AB:   Parasitic plants in the Scrophulariaceae develop infective root structures called haustoria in response to chemical signals released from host-plant roots. This study used a simple in vitro assay to characterize natural and synthetic molecules that induce haustoria in the facultative parasite Triphysaria versicolor. Several phenolic acids, flavonoids, and the quinone 2,6-dimethoxy-p-benzoquinone induced haustoria in T. versicolor root tips within hours after treatment. The concentration at which different molecules were active varied widely, the most active being 2,6-dimethoxy-p-benzo-quinone and the anthocyanidin peonidin. Maize (Zea mays) seeds are rich sources of molecules that induce T. versicolor haustoria in vitro, and chromatographic analyses indicated that the active molecules present in maize-seed rinses include anthocyanins, other flavonoids, and simple phenolics. The presence of different classes of inducing molecules in seed rinses was substantiated by the observation that maize kernels deficient in chalcone synthase, a key enzyme in flavonoid biosynthesis, released haustoria-inducing molecules, although at reduced levels compared with wild-type kernels. We discuss these results in light of existing models for host perception in the related parasitic plant Striga.

AB:   Photosynthesis and photoinhibition in field-grown rice (Oryza sativa L.) were examined in relation to leaf age and orientation. Two varieties (IR72 and IR65598-112-2 [BSI2O6]) were grown in the field in the Philippines during the dry season under highly irrigated, well-fertilized conditions. Flag leaves were examined 60 and 100 d after transplanting. Because of the upright nature of 60-d-old rice leaves, patterns of photosynthesis were determined by solar movements: light falling on the exposed surface in the morning, a low incident angle of irradiance at midday, and light striking the opposite side of the leaf blade in the afternoon. There was an early morning burst of CO2 assimilation and high levels of saturation of photosystem II electron transfer as incident irradiance reached a maximum level. However, by midday the photochemical efficiency increased again almost to maximum. Leaves that were 100 d old possessed a more horizontal orientation and were found to suffer greater levels of photoinhibition than younger leaves, and this was accompanied by increases in the de-epoxidation state of the xanthophyll cycle. Older leaves had significantly lower chlorophyll content but only slightly diminished photosynthesis capacity.

AB:   Phosphoenolpyruvate carboxylase (PEPC) activity was detected in aleurone-endosperm extracts of barley (Hordeum vulgare) seeds during germination, and specific anti-sorghum (Sorghum bicolor) C4 PEPC polyclonal antibodies immunodecorated constitutive 103-kD and inducible 108-kD PEPC polypeptides in western analysis. The 103- and 108-kD polypeptides were radiolabeled in situ after imbibition for up to 1.5 d in 32P-labeled inorganic phosphate. In vitro phosphorylation by a Ca2+-independent PEPC protein kinase (PK) in crude extracts enhanced the enzyme's velocity and decreased its sensitivity to L-malate at suboptimal pH and [PEP]. Isolated aleurone cell protoplasts contained both phosphorylated PEPC and a Ca2+-independent PEPC-PK that was partially purified by affinity chromatography on blue dextran-agarose. This PK activity was present in dry seeds, and PEPC phosphorylation in situ during imbibition was not affected by the cytosolic protein-synthesis inhibitor cycloheximide, by weak acids, or by various pharmacological reagents that had proven to be effective blockers of the light signal transduction chain and PEPC phosphorylation in C4 mesophyll protoplasts. These collective data support the hypothesis that this Ca2+-independent PEPC-PK was formed during maturation of barley seeds and that its presumed underlying signaling elements were no longer operative during germination.

AB:   In maize (Zea mays L.) two leaf-specific ferredoxin (Fd) isoproteins, Fd I and Fd II, are distributed differentially in mesophyll and bundle-sheath cells. A novel cDNA encoding the precursor of Fd II (pFD2) was isolated by heterologous hybridization using a cDNA for Fd I (pFD1) as a probe. The assignment of the cDNAs to the Fds was verified by capillary liquid-chromatography/electrospray ionization-mass spectrometry. RNA-blot analysis demonstrated that transcripts for Fd I and Fd II accumulated specifically in mesophyll and bundle-sheath cells, respectively. The mature regions of pFD1 and pFD2 were expressed in Escherichia coli as functional Fds. Fd I and Fd II had similar redox potentials of -423 and -406 mV, respectively, but the Km value of Fd-NADP+ reductase for Fd II was about 3-fold larger than that for Fd I. Asparagine at position 65 of Fd II is a unique residue compared with Fd I and other Fds from various plants, which have aspartic acid or glutamic acid at the corresponding position as an electrostatic interaction site with Fd-NADP+ reductase. Substitution of asparagine-65 with aspartic acid increased the affinity of Fd II with Fd-NADP+ reductase to a level comparable to that of Fd I. These structural and functional differences of Fd I and Fd II may be related to their cell-specific expression in the leaves of a C4 plant.

AB:   Nicotianamine synthase (NAS), the key enzyme in the biosynthetic pathway for the mugineic acid family of phytosiderophores, catalyzes the trimerization of S-adenosylmethionine to form one molecule of nicotianamine. We purified NAS protein and isolated the genes nas1, nas2, nas3, nas4, nas5-l, nas5-2, and nas6, which encode NAS and NAS-like proteins from Fe-deficient barley (Hordeum vulgare L. cv Ehimehadaka no.1) roots. Escherichia coli expressing nas1 showed NAS activity, confirming that this gene encodes a functional NAS. Expression of nas genes as determined by northern-blot analysis was induced by Fe deficiency and was root specific. The NAS genes form a multigene family in the barley and rice genomes.

AB:   Root elongation, hematoxylin staining, and changes in the ultrastructure of root-tip cells of an Al-tolerant maize variety (Zea mays L. C 525 M) exposed to nutrient solutions with 20 micromolar Al (2.1 micromolar Al3+ activity) for 0, 4, and 24 h were investigated in relation to the subcellular distribution of Al using scanning transmission electron microscopy and energy-dispersive x-ray microanalysis on samples fixed by different methods. Inhibition of root-elongation rates, hematoxylin staining, cell wall thickening, and disturbance of the distribution of pyroantimoniate-stainable cations, mainly Ca, was observed only after 4 and not after 24 h of exposure to Al. The occurrence of these transient, toxic Al effects on root elongation and in cell walls was accompanied by the presence of solid Al-P deposits in the walls. Whereas no Al was detectable in cell walls after 24 h, an increase of vacuolar Al was observed after 4 h of exposure. After 24 h, a higher amount of electron-dense deposits containing Al and P or Si was observed in the vacuoles. These results indicate that in this tropical maize variety, tolerance mechanisms that cause a change in apoplastic Al must be active. Our data support the hypothesis that in Al-tolerant plants, Al can rapidly cross the plasma membrane; these data clearly contradict the former conclusions that Al mainly accumulates in the apoplast and enters the symplast only after severe cell damage has occurred.

AB:   The quantitative analysis with immunogold-electron microscopy using a single-affinity-purified anti-NADH glutamate synthase (GOGAT) immunoglobulin G (IgG) as the primary antibody showed that the NADH-GOGAT protein was present in various forms of plastids in the cells of the epidermis and exodermis, in the cortex parenchyma, and in the vascular parenchyma of root tips (<10 mm) of rice (Oryza sativa) seedlings supplied with 1 mM NH4+ for 24 h. The values of the mean immunolabeling density of plastids were almost equal among these different cell types in the roots. However, the number of plastids per individual cell type was not identical, and some parts of the cells in the epidermis and exodermis contained large numbers of plaslids that were heavily immunolabeled. Although there was an indication of labeling in the mitochondria using the single-affinity-purified anti-NADH-GOGAT IgG, this was not confirmed when a twice-affinity-purified IgG was used, indicating an exclusively plastidial location of the NADH-GOGAT protein in rice roots. These results, together with previous work from our laboratory (K. Ishiyama, T. Hayakawa, and T. Yamaya [1998] Planta 204: 288-294), suggest that the assimilation of exogeneously supplied NH4+ ions is primarily via the cytosolic glutamine synthetase/plastidial NADH-GOGAT cycle in specific regions of the epidermis and exodermis in rice roots. We also discuss the role of the NADH-GOGAT protein in vascular parenchyma cells.

AB:   A simple and efficient protocol is described for regeneration of wild sorghum (Sorghum dimidiatum) from cell suspension cultures. Fast-growing cell suspensions were established from shoot-meristem-derived callus. Plating of the suspension on Murashige and Skoog agar medium supplemented with 2.5 mg 1-1 2,4-dichlorophen-oxyacetic acid (2,4-D) resulted in the formation of embryogenic calli. High-frequency (80%) somatic embryogenesis from small cell clusters (300-400 micrometer) was observed when the cultures were initially maintained in liquid medium with reduced levels of 2,4-D (0.25 mg l-1), followed by transfer to regeneration medium. Direct plating of these small clusters on regeneration medium or transfer to liquid regeneration medium containing kinetin and 6-benzylaminopurine resulted in the development of mature somatic embryos and plantlets. The regenerants developed to maturity and were all phenotypically and cytologically normal.

These units are surrounded by conspicuous cell walls visible in light microscopy after staining with basic fuchsin. Transmission electron microscopy revealed that embryogenic cells are rich in endoplasmic reticulum, polysomes and small protein bodies, and that the outermost layer of their cell walls is composed of fibrillar material. Electron microscopy has also shown that this material covers the surface of embryogenic cells as a distinct layer which we denote as extracellular matrix surface network (ECMSN). Employing histochemical staining with beta-glucosyl Yariv phenylglycoside, we localized arabinogalactan-proteins (AGPs) to the outer cell walls of embryogenic units including ECMSN. The most prominent staining was found in cell-cell junction domains. Large non-embryogenic callus cells were not stained with this AGP-specific dye. Immunofluorescence and silver-enhanced immunogold labelling using monoclonal antibody JIM4 has shown that the ECMSN of embryogenic cells is equipped with JIM4 epitope, while non-embryogenic callus cells are devoid of this epitope. We propose that some specific AGPs of the ECMSN might be relevant for cell-cell adhesion and recognition of embryogenic cells during early embryogenic stages, and that the JIM4 antibody can serve as an early marker of embryogenic competence in maize callus culture.

AB:   We investigated whether a Na-K polyacrylate polymer could be used to remediate a sandy soil artificially contaminated with copper. An experiment, carried out in solution culture, showed that ionic copper was rapidly trapped within the polymer to a maximum content of c. 190 mg Cu g-1 dry polymer, the proportion needed for chelation of each copper ion by four carboxylic groups present in the polymer chains. Cu-EDTA was not retained by the polymer. Growth of perennial ryegrass in 10 kg pots was stimulated in the gel amended soil, and even in the pots with the highest levels of copper, growth was much less impaired than in pots without polymer. Copper concentrations of the shoots were smaller in the plants cultivated in the amended soil. Water extractable copper was considerably reduced in the contaminated gel-amended soil and polymer particles removed from the soil were shown to contain high levels of copper.

AB:   The effect of nitrogen fertilizer inputs to cereal crops on nitrate leaching after harvest was tested on 21 experiments on sandy soils in England. At small nitrogen fertilizer rates leaching increased very little with increasing inputs, while at high rates more than half of any additional nitrogen could be accounted for as increase in nitrate leached. In many cases the response fitted two straight lines. Nitrogen offtake in grain also fitted two straight lines, with a form which complemented the leaching response. The gradient averaged 0.52 kg N in grain for every additional 1 kg N applied below the break point, but only 0.05 kg/kg above. The break points were generally close to or above the economic optimum N input. The effect of inputs on leaching could he quantitatively related to nitrogen offtake in grain, assuming a constant ratio of nitrogen in grain to total nitrogen uptake. The results show that fields receiving N inputs in excess of the economic optimum cause a disproportionately large nitrate loss. However because of uncertainty in predicting the break point in advance, modest further reduction in leaching will occur by reducing inputs to somewhat below the expected economic optimum.

AB:   We examined the dynamics of inorganic P(Pi) and organic P(Po) pools of a savanna Alfisol under continuous cultivation complemented with nitrogen (N) and phosphorus (P) fertilizers with or without cow manure (D), using a modified Hedley fractionation. Continuous cultivation without P fertilizer decreased the concentration of Pi and Po pools including the residual P fraction compared with an unfertilized treatment with natural vegetation. Adding P fertilizers alone or in combination with D (P, NPK, D+P, D+NP and D+NPK) increased the concentration of labile Pi pools, but decreased the concentration of Po pools and the residual P fraction. The tendency of the residual P fraction to decrease along with Po pools suggested that the residual P fraction was largely Po. This is consistent with the correlation between the residual P fraction and total Po (r=0.74**) and the residual P fraction and organic carbon content (r=0.47**). Analysis of the relationships between plant available P, estimated by resin-extractable P, and the more stable Pi and Po pools indicated that 85% of the variation in resin-P was attributable to the hydroxide extractable Pi (OH-Pi) and HCl-Pi which acted as sinks for fertilizer-P. The contribution of the residual P fraction to resin-P was indirect via bicarbonate-extractable Po (HCO3-Po and OH-Po. These results also clarify why attempts to find P extraction methods which correlate well with response to P and to P uptake in the savanna have given inconsistent results.

AB:   According to monthly IRI scanner data for January 1993 to March 1998, cereal prices declined even after adjusting for trade promotions and reduced manufacturer coupons during the public campaign in 1995 and early 1996, as well as after the industry's announced shelf price reductions in Spring 1996. The gap between branded and private label prices also declined. This was due to unexpected increases in private label prices during the jawboning campaign as well as decreases in branded prices. As predicted by the Dorfman Steiner theorem, branded advertising declined when the price cuts reduced brand price cost margins. Quaker's lower priced bagged copies of other firms' leading brands have grown rapidly and advanced Quaker's market share to over 10%, as Kellogg's share continues to decline and General Mills' share is stable. Consumer benefits due to lower prices for the 35-month period commencing April 2, 1995 are 2.633 billion dollars.

AB:   This report examines the conduct of the cereal industry since the advent of our public campaign for lower cereal prices one year ago, on March 5, 1995. Announced cereal price increases slowed for the first time in a decade. But the fact that the major cereal companies sold 145 million fewer boxes of cereal in 1995 indicates that consumers still believe prices continue to be too high. It remains to be seen whether or not the leading companies will move prices more in line with the costs of production due to competition from private label and consumer dissatisfaction.

AB:   This article responds to key points in the GMA Fact Sheet Analysis of cereal industry conduct and performance. It also explains the organization of the industry using research by Wall Street analysts that document high concentration, barriers to entry, and noncompetitive pricing games. The result is high price cost margins and high prices. The judge's decision in State of New York v. P. Morris Kraft General Foods et al. is critiqued. She relies upon a broad definition of competition that compromises the role of price in achieving allocative efficiency in markets. The new application of the antitrust laws to unilateral market power is explained. Finally the prospects for price relief through expansion of private label cereals, although complex, are reasonably good.

AB:   This summary of my recommendations as advisor to the US District Court in an antitrust proceeding involving the acquisition by Post of Nabisco Cereals is based almost entirely on the evidence in that case. There is ample basis for dissatisfaction with the performance of the industry--especially with its comparative absence of everyday price competition, except where private brands bulk large. There is no reason to believe, however, that the merger at issue would weaken price competition or that if Nabisco were sold to some other entity it would be any more willing to dilute the value of its Shredded Wheat brand by selling product for private labeling. On the other hand, the merger would probably make the combined entity more effective in the ways in which the industry typically competes--including heavy distribution of coupons and specials, which are undeniably a form of price competition.

Cereal prices have risen less than the food-at-home CPI. The cereal industry is extremely competitive, moreover manufacturers do not set retail prices. Coupons significantly reduce the prices consumers pay, and cereal prices in the US are not as high as in many other countries.

AB:   A report was issued on March 7, 1995 which found that cereal industry prices have accelerated faster than other foods to high noncompetitive levels. The leading companies' differentiation strategy has constrained the growth of economical private label cereals. Furthermore, reliance on inefficient coupons and promotions do not provide real value to the vast majority of American consumers. We conclude that in a competitive cereal industry, one or more manufacturers would break from the pack, cease expensive product proliferation, and reduce prices. Price competitive companies could continue to make healthy profits by reducing excessive advertising and eliminating inefficient promotions, which total hundreds of millions of dollars each year.

AB:   This article introduces the Forum by explaining the sequence of events related to the jawboning campaign and subsequent reductions in cereal prices. It also introduces the main issues on the vigor of competition and pricing that are analyzed in subsequent papers. Jawboning as a public policy strategy is assessed and found useful in certain circumstances such as those in the breakfast cereal industry in the mid-1990s. The jawboning campaign was effective in advancing price competition in an industry that successfully resisted repeated antitrust efforts to promote competition. The RTE cereal industry is now undergoing major structural changes that are on balance pro-competitive.

AB:   Experiments were designed to determine the relevance of enzyme partitioning, between the cellulose and non-cellulose components of pretreated biomass, with respect to rates of cellulose saccharification in a typical biomass-to-ethanol process. The experimental system included three cellulose preparations (differing in physicochemical properties): a representative lignin-rich noncellulosic residue (prepared from dilute acid-pretreated switchgrass), an acid-extracted lignin preparation, and a complete Trichoderma reesei cellulase preparation. Enzyme-reactor conditions were typical of those commonly used in biomass-to-ethanol studies. The results were found to be dependent on both the lignin and cellulose preparations used. The noncellulosic lignacious residue, when supplemented at up to 40% (w/w) in cellulose-cellulase reaction mixtures, had little effect on rates and extents of cellulose saccharification. Overall, the results suggest that enzyme partitioning between cellulose and the noncellulosic component of a pretreated feedstock is not likely to have a major impact on cellulose saccharification in typical biomass-to-ethanol processes.

AB:   Bouteloua aristidoides and B. eriopoda (Gramineae: Chloridoideae) have long been resident in separate subgenera or genera, Bouteloua s. str. and Chondrosium, respectively, because they differ in number of branches per inflorescence, branch length, number of spikelets per branch, and branches deciduous versus persistent. However, the species are similar in spikelet orientation and form, including lodicules and the abaxial epidermis of the fertile lemma, and in transverse structure of the leaf blade. These two species, together with B. annua and B. eriostachya (first described as a variety of B. eriopoda), uniquely share a suite of morphological and leaf blade anatomical characteristics. A close relationship among these four species is hypothesized. In light of these findings, recognition of Chondrosium either as a subgenus or genus is discouraged. Other findings include much variation in anther and stigma size and confirmation of cleistogamy in B. aristidoides, cleistogamy and chasmogamy in B. annua, chasmogamy in B. eriopoda and B. eriostachya, inflorescence branch abscission in B. eriostachya, spikelet disarticulation preceding branch abscission in B. annua and some B. aristidoides, a thin outer wall of lemma short cells, and a predicted NAD-ME pathway of C4 photosynthesis from leaf blade structure. Divergence (speciation) of B. aristidoides may have been associated with a shift to annuality and autogamy to avoid drought, which predisposed the species for success in disturbed habitats. These characteristics plus epizoochory likely account for its wide, amphitropical distribution.

AB:   Acetyl-coenzyme A carboxylase (ACCase) isozymes were separated from cyclohexanedione-resistant and -susceptible maize. ACCase240 from resistant maize was 3.7-, > 77-, and 12.8-fold more resistant to inhibition by clethodim, sethoxydim, and tralkoxydim, respectively, than ACCase240 from susceptible maize. The resistant ACCase240 preparation had 3.0-fold more protein and 14.5-fold lower specific activity than susceptible ACCase240. Resistant ACCase240 has a Vmax 5.5-fold lower than that of susceptible ACCase240, whereas apparent Km values were similar. ACCase220 from resistant maize was > 25- and 7.2-fold more resistant to inhibition by sethoxydim and tralkoxydim, respectively, than susceptible ACCase220 but was inhibited to the same extent by clethodim. In summary, sethoxydim-resistant corn has an altered herbicide-resistant ACCase220 isozyme and increased expression of a less efficient, herbicide-resistant ACCase240 isozyme. However, to what extent alteration of both isozymes contributes to sethoxydim resistance is not clear.

AB:   The role of acid secretion in regulating short-term changes in growth rate and wall extensibility was investigated in emerging first leaves of intact, water-stressed maize (Zea mays L.) seedlings. A novel approach was used to measure leaf responses to injection of water or solutions containing potential regulators of growth. Both leaf elongation and wall extensibility, as measured with a whole-plant creep extensiometer, increased dramatically within minutes of injecting water, 0.5 mM phosphate, or strong (50 mM) buffer solutions with pH less than or equal to 5.0 into the cell-elongation zone of water-stressed leaves. In contrast, injecting buffer solutions at pH greater than or equal to 5.5 inhibited these fast responses. Solutions containing 0.5 mM orthovanadate or erythrosin B to inhibit wall acidification by plasma membrane H+ -ATPases were also inhibitory. Thus, cell wall extensibility and leaf growth in water-stressed plants remained inhibited, despite the increased availability of (injected) water when accompanying increases in acid-induced wall loosening were prevented. However, growth was stimulated when pH 4.5 buffers were included with the vanadate injections. These findings suggest that increasing the availability of water to expanding cells in water-stressed leaves signals rapid increases in outward proton pumping by plasma membrane H+ -ATPases. Resultant increases in cell wall extensibility participate in the regulation of water uptake, cell expansion, and leaf growth.

AB:   Acclimation of photosynthesis to elevated CO2 has previously been shown to be more pronounced when N supply is poor. Is this a direct effect of N or an indirect effect of N by limiting the development of sinks for photoassimilate? This question was tested by growing a perennial ryegrass (Lolium perenne) in the field under elevated (60 Pa) and current (36 Pa) partial pressures of CO2 (pCO2) at low and high levels of N fertilization. Cutting of this herbage crop at 4- to 8-week intervals removed about 80% of the canopy, therefore decreasing the ratio of photosynthetic area to sinks for photoassimilate. Leaf photosynthesis, in vivo carboxylation capacity, carbohydrate, N, ribulose-1,5-bisphosphate carboxylase/oxygenase, sedoheptulose-1,7-bisphosphatase, and chloroplastic fructose-1,6-bisphosphatase levels were determined for mature lamina during two consecutive summers. Just before the cut, when the canopy was relatively large, growth at elevated pCO2 and low N resulted in significant decreases in carboxylation capacity and the amount of ribulose-1,5-bisphosphate carboxylase/oxygenase protein. In high N there were no significant decreases in carboxylation capacity or proteins, but chloroplastic fructose-1,6-bisphosphatase protein levels increased significantly. Elevated pCO2 resulted in a marked and significant increase in leaf carbohydrate content at low N, but had no effect at high N. This acclimation at low N was absent after the harvest, when the canopy size was small. These results suggest that acclimation under low N is caused by limitation of sink development rather than being a direct effect of N supply on photosynthesis.

AB:   Carbohydrate metabolism of barley (Hordeum vulgare) leaves induced to accumulate sucrose (Suc) and fructans was investigated at the single-cell level using single-cell sampling and analysis. Cooling of the root and shoot apical meristem of barley plants led to the accumulation of Suc and fructan in leaf tissue. Suc and fructan accumulated in both mesophyll and parenchymatous bundle-sheath (PBS) cells because of the reduced export of sugars from leaves under cooling and to increased photosynthesis under high photon fluence rates. The general trends of Suc and fructan accumulation were similar for mesophyll and PBS cells. The fructan-to-Suc ratio was higher for PBS cells than for mesophyll cells, suggesting that the threshold Suc concentration needed for the initiation of fructan synthesis was lower for PBS cells. Epidermal cells contained very low concentrations of sugar throughout the cooling experiment. The difference in Suc concentration between control and treated plants was much less if compared at the single-cell level rather than the whole-tissue level, suggesting that the vascular tissue contains a significant proportion of total leaf Suc. We discuss the importance of analyzing complex tissues at the resolution of individual cells to assign molecular mechanisms to phenomena observed at the whole-plant level.

AB:   Global minimum temperatures (T(MIN)) are increasing faster than maximum temperatures, but the ecological consequences of this are largely unexplored long-term data sets from the shortgrass steppe were used to identify correlations between T(MIN) and several vegetation variables. This ecosystem is potentially sensitive to increases in T(MIN). Most notably, increased spring T(MIN) was correlated with decreased net primary production by the dominant C4 grass (Bouteloua gracilis) and with increased abundance and production by exotic and native C3 forbs. Reductions in B. gracilis may make this system more vulnerable to invasion by exotic species and Less tolerant of drought and grazing.

AB:   Elongation rates of barley (Hordeum vulgare L. cv Hanna) leaves decreased with decreasing soil water content, whereas the pH of xylem sap increased from 5.9 to 6.9 over 6 d as the soil dried. The reduction in leaf-elongation rate (LER) was correlated with the increase in sap pH. Artificial sap buffered to different pH values was fed via the subcrown internode to derooted seedlings. Although leaves elongated at in planta rates when fed artificial sap at a well-watered pH of 6.0, LER declined with increasing sap pH. This effect persisted in the light and in the dark. pH had no effect on the relative water content or the bulk abscisic acid (ABA) concentration of the growing zone of these leaves. LERs of the ABA-deficient mutant Az34 were uniformly high over the pH range tested, whereas those of its isogenic wild-type cultivar Steptoe were reduced as the artificial sap pH was increased from 6.0 to 7.0. However, supplying a well-watered concentration of ABA (3 x 10(-8) M) in the artificial xylem sap restored the pH response of the Az34 mutant. The results suggest that increased xylem sap pH acts as a drought signal to reduce LER via an ABA-dependent mechanism.

AB:   High-affinity K+ uptake in plant roots is rapidly up-regulated when K+ is withheld and down-regulated when K+ is resupplied. These processes make important contributions to plant K+ homeostasis. A cDNA coding for a high-affinity K+ transporter, HKT1, was earlier cloned from wheat (Triticum aestivum L.) roots and functionally characterized. We demonstrate here that in both barley (Hordeum vulgare L.) and wheat roots, a rapid and large up-regulation of HKT1 mRNA levels resulted when K+ was withdrawn from growth media. This effect was specific for K+; withholding N caused a modest reduction of HKT1 mRNA levels. Up-regulation of HKT1 transcript levels in barley roots occurred within 4 h of removing K+, which corresponds to the documented increase of high-affinity K+ uptake in roots following removal of K+. Increased expression of HKT1 mRNA was evident before a decline in total root K+ concentration could be detected. Resupply of 1 mM K+ was sufficient to strongly reduce HKT1 transcript levels. In wheat root cortical cells, both membrane depolarizations in response to 100 micromolar K+, Cs+, and Rb+, and high-affinity K+ uptake were enhanced by K+ deprivation. Thus, in both plant systems the observed physiological changes associated with manipulating external K+ supply were correlated with levels of HKT1 mRNA expression. Implications of these findings for K+ sensing and regulation of the HKT1 mRNA levels in plant roots are discussed.

AB:   Pathogenesis-related proteins from intercellular fluid washings of stressed barley (Hordeum vulgare L.) leaves were analyzed to determine their binding to various water-insoluble polysaccharides. Three proteins (19, 16, and 15 kD) bound specifically to several water-insoluble beta-1,3-glucans. Binding of the barley proteins to pachyman occurred quickly at 22 degrees C at pH 5.0, even in the presence of 0.5 M NaCl, 0.2 M urea, and 1% (v/v) Triton X-100. Bound barley proteins were released by acidic treatments or by boiling in sodium dodecyl sulfate. Acid-released barley proteins could bind again specifically and singly to pachyman. Water-soluble laminarin and carboxymethyl-pachyman competed for the binding of the barley proteins to pachyman. The N-terminal sequence of the 19-kD barley beta-1,3-glucan-binding protein showed near identity to the barley seed protein BP-R and high homology to other thaumatin-like (TL) permatins. The 16-kD barley protein was also homologous to TL proteins, whereas the 15-kD barley protein N-terminal sequence was identical to the pathogenesis-related Hv-1 TL protein. Antifungal barley protein BP-R and corn (Zea mays) zeamatin were isolated by binding to pachyman. Two extracellular proteins from stressed pea (Pisum sativum L.) also bound to pachyman and were homologous to TL proteins.

AB:   Hexokinase (HXK; EC 2.7.1.1) regulates carbohydrate entry into glycolysis and is known to be a sensor for sugar-responsive gene expression. The effect of abiotic stresses on HXK activity was determined in seedlings of the flood-tolerant plant Echinochloa phyllopogon (Stev.) Koss and the flood-intolerant plant Echinochloa crus-pavonis (H.B.K.) Schult grown aerobically for 5 d before being subjected to anaerobic, chilling, heat, or salt stress. HXK activity was stimulated in shoots of E. phyllopogon only by anaerobic stress. HXK activity was only transiently elevated in E. crus-pavonis shoots during anaerobiosis. In roots of both species, anoxia and chilling stimulated HXK activity. Thus, HXK is not a general stress protein but is specifically induced by anoxia and chilling in E. phyllopogon and E. crus-pavonis. In both species HXK exhibited an optimum pH between 8.5 and 9.0, but the range was extended to pH 7.0 in air-grown E. phyllopogon to 6.5 in N2-grown E. phyllopogon. At physiologically relevant pHs (6.8 and 7.3, N2 and O2 conditions, respectively), N2-grown seedlings retained greater HXK activity at the lower pH. The pH response suggests that in N2-grown seedlings HXK can function in a more acidic environment and that a specific isozyme may be important for regulating glycolytic activity during anaerobic metabolism in E. phyllopogon.

AB:   In animal cell lysates the multiprotein heat-shock protein 90 (hsp90)-based chaperone complexes consist of hsp70, hsp40, and p60. These complexes act to convert steroid hormone receptors to their steroid-binding state by assembling them into heterocomplexes with hsp90, p23, and one of several immunophilins. Wheat germ lysate also contains a hsp90-based chaperone system that can assemble the glucocorticoid receptor into a functional heterocomplex with hsp90. However, only two components of the heterocomplex-assembly system, hsp90 and hsp70, have thus far been identified. Recently, purified mammalian p23 preadsorbed with JJ3 antibody-protein A-Sepharose pellets was used to isolate a mammalian p23-wheat hsp90 heterocomplex from wheat germ lysate (J.K. Owens-Grillo, L.F. Stancato, K. Hoffmann, W.B. Pratt, and P. Krishna [1996] Biochemistry 35: 15249-15255). This heterocomplex was found to contain an immunophilin(s) of the FK506-binding class, as judged by binding of the radiolabeled immunosuppressant drug [3H]FK506 to the immune pellets in a specific manner. In the present study we identified the immunophilin components of this heterocomplex as FKBP73 and FKBP77, the two recently described high-molecular-weight FKBPs of wheat. In addition, we present evidence that the two FKBPs bind hsp90 via tetratricopeptide repeat domains. Our results demonstrate that binding of immunophilins to hsp90 via tetratricopeptide repeat domains is a conserved protein interaction in plants. Conservation of this protein-to-protein interaction in both plant and animal cells suggests that it is important for the biological action of the high-molecular-weight immunophilins.

AB:   A possible function for the alternative (nonphosphorylating) pathway is to stabilize the reduction state of the ubiquinone pool (Qr/Qt), thereby avoiding an increase in free radical production. If the Qr/Qt were stabilized by the alternative pathway, then Qr/Qt should be less stable when the alternative pathway is blocked. Qr/Qt increased when we exposed roots of Poa annua (L.) to increasing concentrations of KCN (an inhibitor of the cytochrome pathway). However, when salicylhydroxamic acid, an inhibitor of the alternative pathway, was added at the same time, Qr/Qt increased significantly more. Therefore, we conclude that the alternative pathway stabilizes Qr/Qt. Salicylhydroxamic acid increasingly inhibited respiration with increasing concentrations of KCN. In the experiments described here the alternative oxidase protein was invariably in its reduced (high-activity) state. Therefore, changes in the reduction state of the alternative oxidase cannot account for an increase in activity of the alternative pathway upon titration with KCN. The pyruvate concentration in intact roots increased only after the alternative pathway was blocked or the cytochrome pathway was severely inhibited. The significance of the pyruvate concentration and Qr/Qt on the activity of the alternative pathway in intact roots is discussed.

AB:   Chitin, a linear polysaccharide composed of (1 leads to 4)-linked 2-acetamido-2-deoxy-beta-D-glucopyranose (GlcNAc) residues, and chitosan, the fully or partially N-acetylated, water-soluble derivative of chitin composed of (1 leads to 4)-linked GlcNAc and 2-amino-2-deoxy-beta-D-glucopyranose (GlcN), have been proposed as elicitors of defense reactions in higher plants. We tested and compared the ability of purified (1 leads to 4)-linked oligomers of GlcNAc (tetramer to decamer) and of GlcN (pentamer and heptamer) and partially N-acetylated chitosans with degrees of acetylation (DA) of 1%, 15%, 35%, 49%, and 60%, and average degrees of polymerization between 540 and 1100 to elicit phenylalanine ammonia-lyase (PAL) and peroxidase (POD) activities, lignin deposition, and microscopically and macroscopically visible necroses when injected into the intercellular spaces of healthy, nonwounded wheat (Triticum aestivum L.) leaves. Purified oligomers of (1 leads to 4)-linked GlcN were not active as elicitors, whereas purified oligomers of (1 leads to 4)-linked GlcNAc with a degree of polymerization greater than or equal to 7 strongly elicited POD activities but not PAL activities. Partially N-acetylated, polymeric chitosans elicited both PAL and POD activities, and maximum elicitation was observed with chitosans of intermediate DAs. All chitosans but not the chitin oligomers induced the deposition of lignin, the appearance of necrotic cells exhibiting yellow autofluorescence under ultraviolet light, and macroscopically visible necroses; those with intermediate DAs were most active, These results suggest that different mechanisms are involved in the elicitation of POD activities by GlcNAc oligomers, and.
       of PAL and POD activities by partially N-acetylated chitosan polymers and that both enzymes have to be activated for lignin biosynthesis and ensuing necrosis to occur.

AB:   It was reported previously that enolase enzyme activity and ENO1 transcript levels are induced by anaerobic stress in maize (Zea mays). Here we show that not all isoforms of maize enolase are anaerobically induced. We cloned and sequenced a second enolase cDNA clone (pENO2) from maize. Sequence analysis showed that pENO2 shares 75.6% nucleotide and 89.5% deduced amino acid sequence identity with pENO1 and is encoded by a distinct gene. Expression of ENO2 is constitutive under aerobic conditions, whereas ENO1 levels are induced 10-fold in maize roots after 24 h of anaerobic treatment. Western-blot analysis and N-terminal sequencing of in vivo-labeled maize roots identified two major proteins selectively synthesized upon anaerobic stress as isozymes of enolase. We describe the expression of enolase in maize roots under anaerobic stress.

AB:   The nucellus is a complex maternal grain tissue that embeds and feeds the developing cereal endosperm and embryo. Differential screening of a barley (Hordeum vulgare) cDNA library from 5-d-old ovaries resulted in the isolation of two cDNA clones encoding nucellus-specific homologs of the vacuolar-processing enzyme of castor bean (Ricinus communis). Based on the sequence of these barley clones, which are called nucellains, a homolog from developing corn (Zea mays) grains was also identified. In dicots the vacuolar-processing enzyme is believed to be involved in the processing of vacuolar storage proteins. RNA-blot and in situ-hybridization analyses detected nucellain transcripts in autolysing nucellus parenchyma cells, in the nucellar projection, and in the nucellar epidermis. No nucellain transcripts were detected in the highly vacuolate endosperm or in the other maternal tissues of developing grains such as the testa or the pericarp. Using an antibody raised against castor bean vacuolar-processing protease, a single polypeptide was recognized in protein extracts from barley grains. Immunogold-labeling experiments with this antibody localized the nucellain epitope not in the vacuoles, but in the cell walls of all nucellar cell types. We propose that nucellain plays a role in processing and/or turnover of cell wall proteins in developing cereal grains.

AB:   Both high- and low-molecular-weight glutenin subunits (LMW-GS) play the major role in determining the viscoelastic properties of wheat (Triticum aestivum L.) flour. To date there has been no clear correspondence between the amino acid sequences of LMW-GS derived from DNA sequencing and those of actual LMW-GS present in the endosperm. We have characterized a particular LMW-GS from hexaploid bread wheat, a major component of the glutenin polymer, which we call the 42K LMW-GS, and have isolated and sequenced the putative corresponding gene. Extensive amino acid sequences obtained directly for this 42K LMW-GS indicate correspondence between this protein and the putative corresponding gene. This subunit did not show a cysteine (Cys) at position 5, in contrast to what has frequently been reported for nucleotide-based sequences of LMW-GS. This Cys has been replaced by one occurring in the repeated-sequence domain, leaving the total number of Cys residues in the molecule the same as in various other LMW-GS. On the basis of the deduced amino acid sequence and literature-based assignment of disulfide linkages, a computer-generated molecular model of the 42K subunit was constructed.

AB:   Microbial populations of 46 commercially produced sorghum beer samples from retail outlets in Johannesburg, South Africa, were enumerated and characterized. Aerobic plate counts, lactic acid bacteria counts and yeast counts were performed by conventional and Petrifilm plating. Conventional methods yielded yeast counts of 7.84 log CFU/ml, lactic acid bacteria counts of 6.44 log CFU/ml and aerobic plate counts of 5.96 log CFU/ml. In comparison, Petrifilm counts were 7.85 log CFU/ml for yeasts, 5.31 log CFU/ml for lactic acid bacteria and 5.34 log CFU/ml for aerobic bacteria. Characterization of 419 predominant bacterial isolates from Standard One Nutrient Agar, MRS Agar and corresponding Petrifilm plates yielded 88.0% lactic acid bacteria, 8.4% Bacillus species, 2.9% Micrococcus species and 0.7% Gram negative bacteria. Composition of predominant lactic acid bacteria populations from Standard One Nutrient Agar and both types of Petrifilm plates showed marginal differences. Increased proportions of heterofermentative lactic acid bacteria were, however, isolated from conventional MRS Agar compared to the modified Petrifilm product which represented the equivalent to MRS Agar.

AB:   Greenhouse experiments were conducted to examine competition between Tylenchorhynchus annulatus and Mesocriconema xenoplax on grain sorghum roots that were colonized by the fungus Macrophomina phaseolina or free from fungus colonization. An incomplete factorial treatment design consisted of two levels of M. phaseolina (0 or 10 colony-forming units/g soil) and 12 T. annulatus:M. xenoplax ratios: 1.000:0; 750:0; 500:0; 250:0; 0:0; 0:250; 0:500; 0:750; 0:1,000; 750:250; 500:500; and 250:750. Plants were harvested after 105 days. Despite similar feeding habits, competition between these ectoparasitic nematode species was limited. Tylenchorhynchus annulatus was more susceptible to antagonism by M. xenoptax than the reverse, but susceptibility depended on initial inoculum ratio. Root colonization by M. phaseolina reduced competitive effects of T. annulatus on M. xenoplax but not the reverse. Both nematode species reduced shoot dry weight but only T. annulatus reduced root dry weight. Both plant weight parameters were reduced by M. phaseolina.

AB:   Long-term exposure of plants to elevated partial pressures of CO2 (pCO2) often depresses photosynthetic capacity. The mechanistic basis for this photosynthetic acclimation may involve accumulation of carbohydrate and may be promoted by nutrient limitation. However, our current knowledge is inadequate for making reliable predictions concerning the onset and extent of acclimation. Many studies have sought to investigate the effects of N supply but the methodologies used generally do not allow separation of the direct effects of limited N availability from those caused by a N dilution effect due to accelerated growth at elevated pCO2. To dissociate these interactions, wheat (Triticum aestivum L.) was grown hydroponically and N was added in direct proportion to plant growth. Photosynthesis did not acclimate to elevated pCO2 even when growth was restricted by a low-N relative addition rate. Ribulose-1,5-bisphosphate carboxylase/oxygenase activity and quantity were maintained, there was no evidence for triose phosphate limitation of photosynthesis, and tissue N content remained within the range recorded for healthy wheat plants. In contrast, wheat grown in sand culture with N supplied at a fixed concentration suffered photosynthetic acclimation at elevated pCO2 in a low-N treatment. This was accompanied by a significant reduction in the quantity of active ribulose-1,5-bisphosphate carboxylase/oxygenase and leaf N content.

AB:   The accumulation of soluble carbohydrates resulting from growth under elevated CO2 may potentially signal the repression of gene activity for the small subunit of ribulose-1,5-bisphosphate carboxylase/oxygenase (rbcS). To test this hypothesis we grew rice (Oryza sativa L.) under ambient (350 microliters L-1) and high (700 microliters L-1) CO2 in outdoor, sunlit, environment-controlled chambers and performed a cross-switching of growth CO2 concentration at the late-vegetative phase. Within 24 h, plants switched to high CO2 showed a 15% and 23% decrease in rbcS mRNA, whereas plants switched to ambient CO2 increased 27% and 11% in expanding and mature leaves, respectively. Ribulose-1,5-bisphosphate carboxylase/oxygenase total activity and protein content 8 d after the switch increased up to 27% and 20%, respectively, in plants switched to ambient CO2, but changed very little in plants switched to high CO2. Plants maintained at high CO2 showed greater carbohydrate pool sizes and lower rbcS transcript levels than plants kept at ambient CO2. However, after switching growth CO2 concentration, there was not a simple correlation between carbohydrate and rbcS transcript levels. We conclude that although carbohydrates may be important in the regulation of rbcS expression, changes in total pool size alone could not predict the rapid changes in expression that we observed.

AB:   Germins and germin-like proteins (GLPs) constitute a ubiquitous family of plant proteins that seem to be involved in many developmental and stress-related processes. Wheat germin has been extensively studied at the biochemical level: it is found in the apoplast and the cytoplasm of germinating embryo cells and it has oxalate oxidase activity (EC 1.2.3.4). Germin synthesis can also be induced in adult wheat leaves by auxins and by a fungal pathogen but it remains to be determined whether the same gene is involved in developmental, hormonal and stress response. In this work, we have studied the expression of one of the wheat germin genes, named gf-2.8, in wheat as well as in transgenic tobacco plants transformed with either this intact gene or constructs with GUS driven by its promoter. This has allowed us to demonstrate that expression of this single gene is both developmentally and pathogen-regulated. In addition, we show that expression of the wheat gf-2.8 germin gene is also stimulated by some abiotic stresses, especially the heavy metal ions Cd2+, Cu2+ and Co2+. Several chemicals involved in stress signal transduction pathways were also tested: only polyamines were shown to stimulate expression of this gene. Because regulation of the wheat gf-2.8 germin gene is complex and because its product results in developmental and stress-related release of hydrogen peroxide in the apoplast, it is likely that it plays an important role in several aspects of plant growth and defence mechanisms.

AB:   To gain insight into the regulatory mechanisms and the signals responsible for the adaptation of higher plants to conditions of varying sulfate availability, we have isolated from a sulfate-deprived root library maize cDNAs encoding sulfate permease (ZmST1) and ATP sulfurylase (ZmAS1), the two earliest components of the sulfur assimilation pathway. The levels of ZmST1 and ZmAS1 transcripts concomitantly increased in both roots and shoots of seedlings grown under sulfate-deprived conditions, and rapidly decreased when the external sulfate supply was restored. This coordinate response, which was not observed under conditions of limiting nitrate or phosphate, correlated with the depletion of glutathione, rather than sulfate stores. However, drastically reducing glutathione levels through treatment with buthionine sulfoximine, a specific inhibitor of gamma-glutamyl cysteine synthetase, did not provide an adequate stimulus for the up-regulation of either sulfate permease or ATP sulfurylase messengers. Indeed, L-cysteine, but not D-cysteine, effectively down-regulated both transcripts when supplied to sulfur-deficient seedlings under conditions of blocked glutathione synthesis. Altogether, these data provide evidence for the coordinate regulation of sulfur assimilation mRNAs in higher plants and for the glutathione-independent involvement of cysteine as a stereospecific pretranslational modulator of the expression of sulfur status-responsive genes.

AB:   Ca2+ in rooting medium is essential for root elongation, even in the absence of added toxicants. In the presence of rhizotoxic levels of Al3+, H+, or Na+ (or other cationic toxicants), supplementation of the medium with higher levels of Ca2+ alleviates growth inhibition. Experiments to determine the mechanisms of alleviation entailed measurements of root elongation in wheat (Triticum aestivum L. cv Scout 66) seedlings in controlled medium. A Gouy-Chapman-Stern model was used to compute the electrical potentials and the activities of ions at the root-cell plasma membrane surfaces. Analysis of root elongation relative to the computed surface activities of ions revealed three separate mechanisms of Ca2+ alleviation. Mechanism I is the displacement of cell-surface toxicant by the Ca2+ -induced reduction in cell-surface negativity. Mechanism II is the restoration of Ca2+ at the cell surface if the surface Ca2+ has been reduced by the toxicant to growth-limiting levels. Mechanism III is the collective ameliorative effect of Ca2+ beyond mechanisms I and II, and may involve Ca2+ -toxicant interaction's at the cell surface other than the displacement interactions of mechanisms I and II. Mechanism I operated in the alleviation of all of the tested toxicities; mechanism II was generally a minor component of alleviation; and mechanism III was toxicant specific and operated strongly in the alleviation of Na+ toxicity, moderately in the alleviation of H+ toxicity, and not at all in the alleviation of Al3+ toxicity.

AB:   Up to 80% of Zea mays L. grain phosphorus is stored in the form of phytin in the embryo. Our objective is to determine the control of phytin mobilization during germination and seedling growth. A maize phytase cDNA, phy S11, has been previously characterized (Maugenest et al., Biochem J 322: 511-517, 1997). In the present work, phy S11 was used to screen a maize genomic library and two distinct genes, PHYT I and PHY II, were isolated and sequenced. The transcribed sequences of these two genes presented a strong homology whereas the untranscribed upstream and downstream sequences appeared very different. Northern blot analysis and in situ hybridization showed a high accumulation of phytase mRNA at the early steps of germination in the coleorhiza, radicle cortex and coleoptile parenchyma. Phytase expression was also detected at a lower extent in the scutellum. In adult plants, northern blot analyses revealed low but significant levels of phytase mRNA in the roots. In situ hybridizations on root cross-sections localized phytase mRNA in rhizodermis, endodermis and pericycle layers. Immunolocalization analysis showed phytase accumulation at the same sites as its mRNA. A RT-PCR approach was used in an attempt to discriminate between the transcripts from each gene in the different situations. These experiments indicate that both genes are expressed during germination, whereas only PHYT I is expressed in adult roots. This suggests that signals responsible for phytase gene expression in roots are different from those responsible for gene expression during germination.

AB:   A Gouy-Chapman-Stern model has been developed for the computation of surface electrical potential of plant cell membranes in response to ionic solutes. The present model is a modification of an earlier version developed to compute the sorption of ions by wheat (Triticum aestivum L. cv Scout 66) root plasma membranes. A single set of model parameters generates values for surface electrical potential that correlate highly with published zeta potentials of protoplasts and plasma membrane vesicles from diverse plant sources. The model assumes ion binding to a negatively charged site (R- = 0.3074 micromoles m-2) and to a neutral site (p0 = 2.4 micromoles m-2) according to the reactions R- + I(Z) reversibly RI(Z-1) and p0 + I(Z) reversibly PI(Z), where I(Z) represents an ion of charge Z. Binding constants for the negative site are 21,500 M-1 for H+, 20,000 M-1 for Al3+, 2,200 M-1 for La3+, 30 M-1 for Ca2+ and Mg2+, and 1 M(-1) for Na+ and K+. Binding constants for the neutral site are 1/180 the value for binding to the negative site. Ion activities at the membrane surface, computed on the basis of surface electric potential, appear to determine many aspects of plant-mineral interactions, including mineral nutrition and the induction and alleviation of mineral toxicities, according to previous and ongoing studies. A computer program with instructions for the computation of surface electrical potential, ion binding, ion concentrations, and ion activities at membrane surfaces may be requested from the authors.

AB:   Intra-nucleosomal cleavage of DNA into fragments of about 200 bp was demonstrated to occur in developing anthers, in which microspores had developed into the mid-late to late uni-nucleate stage in situ, i.e. at the verge of mitosis. The same was observed, but to a much larger extent, if these anthers were pre-treated by a hyper-osmotic shock. Pretreatment of anthers before the actual culture of microspores was required for optimal androgenesis of microspores. The use of the TUNEL reaction, which specifically labels 3' ends of DNA breaks, after intranucleosomal cleavage of DNA, revealed that DNA fragmentation mainly occurred in the loculus wall cells, tapetum cells and filament cells. TUNEL staining was absent or infrequently observed in the microspores of developing anthers in situ. Electron microscopy studies showed condensed chromatin in nuclei of loculus wall cells in the developing anthers. These observations at the chromatin and DNA level are known characteristics of programmed cell death, also known as apoptosis. Features of apoptosis were infrequently found in microspores from freshly isolated mature anthers. However, most tapetum cells had disappeared in these anthers and the remaining cell structures showed loss of cellular content. The viability of microspores in pre-treated anthers was comparable to those in freshly isolated anthers and almost four times higher than in anthers from control experiments. This observation was correlated with three to four times less microspores showing TUNEL staining and a two times higher level of ABA in the anther plus medium samples than in controls. Addition of ABA to the controls enhanced the viability and lowered the occurrence of.
       apoptosis linked characteristics in the microspores. These data suggest that pre-treatment is effective in stimulating androgenesis because it leads to an increase in ABA levels which protects microspores from dying by apoptosis.

AB:   Carpropamid (WIN, KTU 3616) provides good control of leaf and panicle blast by 'one-shot' nursery-box treatment. It inhibits melanin biosynthesis in appressorial cells of Pyricularia oryzae, making them hyaline. Penetration by infection hyphae from the hyaline appressoria into rice epidermal cells is substantially hindered. In addition, the spread of rice blast spores from primary lesions to the other parts of the plant leading to secondary infection is largely prevented when the plants are treated with carpropamid by spray or water surface application. Secondary infection was simulated in a glass chamber fitted with an ultrasonic humidifier. On treated plants, many blast spores formed in the lesions, but the number of air spora that were dispersed from the lesions decreased significantly. A similar suppression of the spore liberation was observed in vitro when lesions on rice leaf segments, or discs from Pyricularia cultures on oatmeal agar were treated with the chemical. Spores from treated lesions or from the cultures on oatmeal agar amended with the chemical germinated normally and produced well-melanized appressoria on cellophane membranes. In addition, the spores proved to be fully pathogenic towards rice seedlings, producing normal disease symptoms. These results strongly suggest that carpropamid reduces the secondary infection of rice by Pyricularia by specifically hindering spore liberation.

AB:   This research investigated parasitism of the buffalograss mealybugs Tridiscus sporoboli (Cockerell) and Trionymus sp. by Rhopus nigroclavatus (Ashmead) through rearing and dissection studies, paired comparison tests, and a field survey. Rates of parasitism reported in this article reflect combined parasitism of the 2 mealybug species. In the rearing study, parasitism of adult female mealybugs by R. nigroclavatus was 48.6%, with an average emergence of 1.77 parasitoids per parasitized mealybug. A maximum of 7 R. nigroclavatus adults emerged from a single mealybug female. Mealybug dissections documented parasitism rates by R. nigroclavatus of 78.5, 67.5, and 4.3%, respectively, for adult females, 3rd and 4th (male pupae) instars, and 1st- and 2nd-instar mealybugs. Results revealed the preference of R. nigroclavatus on buffalograss mealybug populations. Paired comparison tests with and without R. nigroclavatus demonstrated the effectiveness of this parasitoid as a biological control agent for buffalograss mealybugs under greenhouse conditions. Significant differences were detected in the number of nonparasitized mealybugs between treatments containing only mealybugs and treatments containing both mealybugs and parasitoids. Sticky trap captures in the field suggested a functional relationship between the seasonal abundance of R. nigroclavatus and its mealybug hosts.

AB:   Tarhana is a fermented wheat flour-yoghurt mixture which is widely consumed in Turkey. Baker's yeast is also involved in the fermentation. In this study, fermentation activity of tarhana was investigated by monitoring the lactic acid bacteria and yeast population when the level of salt and amount of yoghurt used were varied. Fermentation activity was high during the first day of fermentation. Microbial counts dropped below the initial counts at the end of a 4-day fermentation. Fermentation activity of tarhana prepared without salt was found to he higher than the tarhana samples prepared with salt.

AB:   Objectives: The objectives of this study were to examine variability of folate intake in order to estimate the number of days needed to accurately estimate intakes in women of childbearing age and to simulate the effect of folic acid fortification of cereals and grains on individual folate intake. Design: Observational study of food intake over a 60-day period. Sampling: A convenience sample of 21 women completed food records on randomly assigned days within a 60-day period. Outcomes measured: Folate intake and variance ratios of folate intake. Statistical analysis: Repeated measures analysis of variance. Results: Six days of food records were needed to describe folate intake of these women of childbearing age (18 to 45 years) with 20% attenuation of a correlation coefficient between dietary folate intake and another biological variable. Seven days of records were needed with simulated folic acid fortification (assuming fortification of 140 microgram folic acid per 100 g flour) and 5 days were needed with supplements containing 200 to 400 microgram folic acid in addition to folic acid fortification. Food folate intake was 288+/-195 microgram; only 2 of the participants consumed the recommended 400 microgram. With fortification, folate intake increased to 550+/-279 microgram without supplements and 609+327 microgram with supplements. Applications: Individual intakes of folate should be assessed with at least 7 days of dietary records (20% attenuation). In this sample, when folic acid fortification was added to dietary intake, routine supplementation was not necessary to achieve folate intakes of 400 microgram in the majority of participants. The practice of routine folic acid supplementation should.
       be considered carefully to ensure that individual intakes of folate do not exceed the upper limits of safety.

AB:   While several authors have noted tree regeneration on decaying logs, the role that "nurse logs" play in maintaining tree diversity in eastern North American forests has remained unquantified. We sampled small seedling (less than or equal to 5 cm high) densities of seven tree species on and directly adjacent to logs in two northern hardwood stands in the Adirondack mountains of New York. Polar ordination of 42 microsite plots revealed distinctly different small seedling communities on logs vs. forest floor. Yellow birch and red spruce densities were 24 times and 5 times greater on logs than forest floor, while those of sugar maple and striped maple were 8 times and 4 times greater on the forest floor. Maintaining a natural level (approximately 5% ground cover) of well distributed logs can supplement site preparation techniques such as soil scarification to provide regeneration sites for yellow birch and red spruce, particularly in heavily stocked northern hardwood stands.

AB:   In southern Europe, information on the biological nitrogen (N2) fixation capacity of grain legumes in the field is scarce. At two locations in Portugal on Haplic Luvisols, N2 fixation by fababean, pea and chickpea was evaluated over two consecutive years by the 15N isotope dilution technique, using barley as the control crop. Crop growth and N2 fixation varied between sites and years. The legumes derived more than 60% of their N from the atmosphere under favourable soil conditions, but the proportion was reduced when the availability of soil moisture and molybdenum (Mo) were constrained. Annual rates of N2 fixation by uninoculated fababean varied from 76 to 125 kg N ha(-1), with a regular rainfall distribution during the growth cycle (the first year experiment), and from 55 to 72 kg N ha(-1) under drought stress (the second year experiment). Annual rates of N2 fixation by uninoculated peas varied from 31 to 107 kg N ha(-1) with regular precipitation, and from 4 to 37 kg N ha(-1) under drought stress. Chickpea was tested only in a drought year, when it fixed from 19 to 24 kg N ha(-1). Mean values for N derived from the atmosphere by chickpea varied from more than 70% at one location to less than 45% at another, where Mo was later found to be deficient. Inoculation with Rhizobium leguminosarum did not significantly affect the N2 fixed by fababean in the drought year, whereas peas fixed 50% or more N after inoculation. Inoculation with Bradyrhyzobium cicer did not improve fixation by chickpea. Based on the N economy of the shoots, it appeared that any N addition to the soil in harvest residues varied with crop and location.

AB:   We start by outlining the general effects of climatic variability and temperature extremes on wheat yields in the context of extreme event effects on crop processes for climatic impacts studies. We then review literature describing the responses of wheat plants to extreme temperatures. Cardinal temperature thresholds for different phenological processes in wheat are identified and we outline the effects of temperature on rates of growth and development. Finally, we assess the implications of the above for future climatic impact studies. Our summary shows how relatively small and consistent are the standard errors of the cardinal mean temperatures for many of the processes examined. Cardinal temperatures are conservative between studies and are seemingly well-defined in wheat. Into this category we put the lethal limits for wheat, the sterility response at anthesis, the cardinal temperatures for vernalization and some of the base and optimal temperatures. Important questions for the future involve the effects of combinations of extreme events and the modelling of specific effects such as the influence of high temperatures on grain set.

AB:   The effects of different nitrogen supplies on the performance of the short-day cultivar M9D3 of pearl millet (Pennisetum glaucum L. R.Br.) and their interaction with sowing time were analysed in a two-year experiment in Mali. The first sowing dates coincided with the beginning of the rainy season. The second sowings were 20 days later. The sowing date affected only the emergence-earing duration independently of nitrogen application. The linear reduction in straw yield, caused by the shortening of the cycle, was not combined with a reduction in grain yield. The application of even low levels of nitrogen to millet crops always increased the grain yield, as a consequence of a higher number of productive panicles, while the straw production was positively affected only when the rainy season started early. The non-agreement between the high productive potential of the first sowing crops and their grain yield, in comparison with the plants of the second sowing date, could be ascribed, first of all, to the more marked asynchrony between the time corresponding to LAImax and the grain filling phase, characterised by the maximum sink demand and, second, to a longer time interval during which stem growth and panicle growth are in direct competition.

AB:   The grain protein content (GPC) in barley is influenced to a high degree by the environment and this may cause problems if the barley is intended for malt. Barley used for malt should have a GPC not exceeding 11.5% under any environmental condition. It is, therefore, important to breed for cultivars with low and less environmentally influenced GPC. In a 2-year field experiment seven spring barley (Hordeum vulgare L.) cultivars, with varying GPC stability, were grown at two or three nitrogen application rates, respectively, to determine the differences in leaf area development, N-uptake, yield components, GPC and GPC stability. The time course of leaf area index was followed by measuring light transmission and light reflectance. Total shoot N and biomass and yield components were determined by sub-sampling an area of 3 x 0.25 m(-2) at heading and at maturity. No clear differences were observed in leaf area development between cultivars with low or high GPC stability, but two of the three stable cultivars showed an earlier reduction of the leaf area and less variance in leaf area index during grain filling. Cultivars with low GPC stability tended to be late, had more biomass accumulated at heading, a larger number of ears per m(2), and a higher yield and a lower GPC than more sensitive cultivars. From the results of a factor analysis an ideotype for low and stable GPC is postulated. This type is characterized by late heading, many tillers and many seeds per ear. It is suggested that breeding for a prolonged vegetative period would reduce the environmental effects on GPC.

AB:   Helicoverpa zea reproductive virus (HzRV) is a non-occluded bacilliform virus that affects both female and male moths of the corn earworm H. zea. In order to study the biology and host range of HzRV, a bioassay was previously developed to detect the presence of this virus in infected insects. A drawback of this bioassay is that it is time consuming and requires more than a month to complete. Here we describe the development of a polymerase chain reaction (PCR) assay for the rapid detection of HzRV in infected corn earworms. The genome of HzRV was digested with PstI and cloned into a plasmid vector. Sequences from two different clones, P4 and P13, were selected for designing two sets of primers. These primers were used for PCR and their sensitivity and specificity in detecting HzRV DNA were examined. Both sets of primers produced the expected amplification product in samples containing HzRV DNA but not in uninfected corn earworm samples, Spodoptera frugiperda (Sf-9) cells, or samples from the Autograph californica nuclear polyhedrosis virus. In addition, the primer pair of the clone P13 was sensitive enough to detect approximately 175 copies of viral DNA. We then used this assay to examine feral populations of H. zea from seven geographical locations in the United States. HzRV was detected primarily in the Mississippi populations and to a lesser extent in Iowa and Georgia, but none in Maryland, Missouri and Texas populations. This PCR assay provides highly specific, sensitive, and rapid way of detecting the presence of HzRV and will be useful in further studying the host range, tissue specificity, and incidence of this virus in wild populations of the corn earworm.

AB:   Oxidised starches prepared from corn and waxy amaranth starch under conditions optimised for development for film forming ability were compared with gum arabic and a known substitute of gum arabic for encapsulation of a model flavour compound, vanillin. Percentage vanillin encapsulated using gum arabic, amiogum 688 (a known gum arabic substitute), oxidised corn starch and oxidised amaranth starch differed marginally and were found to be 57.84%, 58.61%. 60.89% and 58.61% respectively of the recoverable vanillin. Results obtained suggest the possibility of using oxidised starch as a substitute for gum arabic in encapsulated flavours with advantages such as freedom from hygroscopicity and similar encapsulation efficiency.

AB:   In a previous study of glucose tolerance, plasma insulin levels were greatly elevated in genetically obese Wistar fatty rats but not lean rats fed a diet containing polyunsaturated fatty acids. In the present study, triacylglycerol-regulation of levels of circulating insulin and glucagon-like peptide-1 (7-36) (GLP-1) has been investigated in these rats. In the glucose tolerance test, the two plasma insulin peaks appeared in obese and lean rats intubated with glucose + corn oil, at 15-30 min and 4 h, whereas only the first peak appeared in rats intubated with glucose alone, although the glucose response did not differ. After intubation of corn oil only, the insulin peak at 15 min was not detected but the peak at 4 h was large. The two plasma GLP-1 peaks appeared 15 min and 4 h after intubation of glucose + corn oil similarly to the insulin responses, although the first peak was small and the second peak was very large. A small peak at 15 min was not significant in rats intubated glucose alone and no peak was seen at 4 h. The GLP-1 concentrations were significantly higher in the following order: portal vein > inferior vena cave > tail vein. The plasma GLP-1 increment in response to oral triacylglycerols was significantly higher in obese rats than in lean rats as was the insulin increment. Thus, oral triacylglycerols (possibly polyunsaturated) appeared to act at the gut lumen to stimulate GLP-1 secretion, which may be responsible for the second (4 h) insulin peak.

AB:   Our study was designed to determine whether hydrogenated fat high in trans monoenes concentration affected prostaglandin synthesis. Corn oil (CO), butter (B), hydrogenated vegetable oil (HF) and coating fat (CF) were used in this study. These fats were fed to rats for 10 wk at 10 g/100 g diet. The phospholipid (PL) fatty acid content of platelets, aorta and heart was determined by gas liquid chromatography, and the in vitro aorta production of prostacyclin (PGI2) from exogenous or endogenous arachidonic acid (AA) was measured using the radioimmuno-assay (RIA) method. Serum thromboxane B2 (TXB2) released by platelets as thromboxane A2 (TXA2) during incubation of whole blood was also measured by this method. In the group fed CF, AA was significantly lower in the PL of aorta, platelet and heart, and the ratio 20:3(n-9)/20:4(n-6) was greater than in the groups fed CO, B or HF, indicating that the group fed CF was essential fatty acid (EFA) deficient. Although AA was significantly lower in the aorta and platelet PL of the group fed HF compared to the group fed CO, that difference did not affect the amounts of PGI2 or TXB2 produced in these groups. The group fed CF had significantly less PGI2 and TXB2 released by aorta and platelets than the other groups. This was the result of the reduced level of AA and the presence of higher amounts of 20:3(n-9) acid in the PL, which might act as a competitive inhibitor for cyclooxygenase. The aortic production of PGI2 from exogenous AA did not differ among the groups indicating that prostaglandin synthetase was not affected by the dietary fat. We conclude that the consumption of hydrogenated fats high in trans 18:1 acids with.
       adequate amount of linoleic acid had no effect on the amount of thromboxane or prostacyclin produced by platelet or aorta in vitro.

AB:   Topical application bioassays of DDT, lindane, malathion, pirimiphos-methyl, deltamethrin, and permethrin were undertaken with 11 held strains of maize weevil, Sitophilus zeamais Motschulsky, collected from nine states in Mexico. Concentration-mortality regression lines were estimated to compare the resistance ratios for each insecticide and strain. For each insecticide, resistance ratios were determined relative to the most susceptible strain. The field-collected strains showed low to moderate levels of resistance to DDT (1.3- to 14.1-fold), moderate to high levels of resistance to lindane (4.7- to 20.9-fold), low to high levels of resistance to malathion (1.6- to 31.4-fold), and low levels of resistance to pirimiphos-methyl (3.0- to 3.7-fold), deltamethrin (1.2- to 1.8-fold), and permethrin (2.3- to 3.5-fold). This is the first report of high levels of lindane and malathion resistance in strains of S. zeamais in Mexico. Given this information, I conclude that insecticide resistance in S. zeamais in Mexico is important, and may become a more serious problem in the future.

AB:   Experiments are described in which data on developmental rate of the lesser grain borer, Rhyzopertha dominica, were collected over a wide range of temperatures (15-39 degrees C) and relative humidities (20-70%). The results differed from previously published work in that development was completed at temperatures as low as 18 degrees C, although only at relative humidities of 55% or above. Development was not completed at less than 30% r.h. at any temperature. In general, the rate of development observed in this study was lower than that in the literature. The data collected from these experiments were used to develop submodels for emergence pattern and rate of development. The derived model of development rate includes both exponential and logarithmic functions of temperature and humidity and does reflect well the critical observed interaction between temperature and relative humidity. This study has important implications for the effective use of grain-cooling with ambient aeration to restrict insect population growth.

AB:   This paper describes a new method for the assessment of weight loss due to insect pests in stored maize cobs. The method involves scoring each cob in the sample on a visual damage scale and then using a simple equation to estimate overall sample weight loss. The coefficients in the equation are determined in advance of field work by calibrating the visual scale against a laboratory loss assessment technique. The visual scale method was found to be rapid, simple and had many advantages for on-farm work. Precision of the results was shown to be similar to that of existing weight loss assessment methods.

AB:   Eight land races of sorghum collected in Ethiopia were found to show significant variation by genotype in soluble phenolic content. Phenolic content, as catechin equivalents, was measured by the Prussian blue procedure. Variation in storage insect resistance was demonstrated using standardized tests with the rice weevil, Sitophilus oryzae. Significant inverse linear relationships were also found between resistance parameters such as weight loss of grain, the Dobie index of susceptibility, number of eggs laid and progeny emerged and the phenolic content of the grain (r(2) = 0.85, 0.55, 0.46 and 0.52 respectively). The results suggest that the soluble phenolic content, which previous studies have shown to consist primarily of proanthocyanidins, can be used as an indicator of resistance.

AB:   The effect of water activity (aw, 0.92-0.98), temperature (15-30 degrees C) and incubation period (2-4 weeks) on growth, calorific losses and fumonisin production by one isolate of Fusarium moniliforme and two of F. proliferatum were studied on maize-based substrates. The calorific losses (kJ) of maize flour due to fungal growth in relation to temperature and aw were quantified and found to be maximal at 0.98 aw (17-64%, after 4 weeks, depending on temperature level) but negligible at 0.92 aw (0-9%). This suggests that growth of mycotoxigenic Fusarium can contribute to both nutritional losses and toxic contamination of staple substrates. Total fumonisin concentrations were optimally produced on ground maize at 30 degrees C and 0.98 aw and were 143.9 micrograms g(-1) for F. moniliforme, and 51.0-104.3 micrograms g(-1) for the F. proliferatum isolates, respectively. In general, both fumonisin production and fungal biomass decreased with temperature and aw. Good correlation was found between fumonisin concentration and fungal biomass, while calorific losses correlated inversely with both fumonisin concentration and fungal biomass. Single, two-, three- and four-way interactions of aw, temperature, time and isolate were all significant (P < 0.01) for calorific losses, and for fumonisin production, with the exception of the aw x temperature x time interaction.

AB:   To determine if spatial variation in soluble carbon sources along the root coincides with different trophic groups of bacteria, copiotrophic and oligotrophic bacteria were enumerated from bulk soil and rhizosphere samples at 2 cm intervals along wheat roots 2, 3, and 4 week's after planting. There was a moderate rhizosphere effect in one experiment with soil rich in fresh plant debris, and a very pronounced rhizosphere effect in the second experiment with soil low in organic matter. We obtained wavelike patterns of both trophic groups of bacteria as well as water-soluble total organic carbon (TOC) along the whole root length (60 or 90 cm). TOC concentrations were maximal at the root tip and base and minimal in the middle part of the roots. Oscillations in populations of copiotrophic and oligotrophic bacteria had two maxima close to the root tip and at the root base, or three maxima close to the tip, in the middle section, and at the root base. The location and pattern of the waves in bacterial populations changed progressively from week to week and was not consistently correlated with TOC concentrations or the location of lateral root formation. Thus, the traditional view that patterns in bacterial numbers along the root directly reflect patterns in exudation and rhizodeposition from several fixed sources along the root may not be true. We attributed the observed wavelike patterns in bacterial populations to bacterial growth and death cycles (due to autolysis or grazing by predators). Considering the root tip as a moving nutrient source, temporal oscillations in bacterial populations at any location where the root tip passed would result in moving waves along the root.
       This change in concept about bacterial populations in the rhizosphere could have significant implications for plant growth promotion and bioremediation.

AB:   The gelation of concentrated barley (1 lead to 3) (1 leads to 4)-beta-glucan solutions was investigated. The gelation rate was quantified by a novel parameter called the elasticity increment I(E), accessible via oscillatory time experiments. Decreasing molar mass and increasing concentration proved to raise the gelation rate. Despite a very similar plateau storage modulus G'p of the final gels for a given concentration, the mechanical stability increases with increasing molar mass. Oat beta-glucan and lichenan, both (1 leads to 3) (1 leads to 4)-beta-glucans, are also able to form solid gels. The turbidity, syneresis, melting temperature of the gels and the gelation rate increase in the order oat beta-glucan, barley beta-glucan and lichenan, indicating an increasing extent of the junction zones. Examination of the fine structure revealed the most regular chain structure for lichenan, with cellotriose units linked by beta-(1 leads to 3) bonds as the main structural feature. From this it was deduced that sections of consecutive cellotriose units constitute the cross-links. A gelation model based on sporadic nucleation similar to crystallization of polymer melts is proposed.

AB:   A (1 leads to 3)(1 leads to 4)-beta-D-glucan isolated from barley by a set of commercial beta-glucans differing in molecular size was characterized by means of viscometry and size exclusion chromatography coupled with multi-angle laser light scattering. A eta(0)-Mw-c relationship (eta(0) = 10(-3) + 6.04 x 10(-5) cMw(0.71) + 2.56 x 10(-6) c(2) Mw(1.42) + 2.70 x 10(-15) c(5.18) Mw(3.68) did not reveal any evidence of association tendencies in the concentrated fresh solution either. However, rheological measurements showed a transition from typical viscoelastic behaviour to gel-like properties over a period of several hours, with a long induction period which allows rheological measurements in the sol state. In shear experiments the concentrated beta-glucan solutions showed flow irregularities correlating with a Weissenberg number (N1/tau) in the range 1-3. Repeated cycles of short-term steady shear and rest periods accelerated the sol-gel transition, whereas steady shear did not induce gelation. Barley beta-glucan in freshly prepared aqueous solution behaves like a viscoelastic liquid, without any associated structures being detected even over a period of several hours, despite its ability to form solid gels.

AB:   Corn fiber consists of about 20% starch, 14% cellulose, and 35% hemicellulose, and has the potential to serve as a low-cost feedstock for production of fuel ethanol. Several pretreatments (hot water, alkali, and dilute acid) and enzymatic saccharification procedures were evaluated for the conversion of corn fiber starch, cellulose, and hemicellulose to monomeric sugars. Hot water pretreatment (121 degrees C, 1 h) facilitated the enzymatic saccharification of starch and cellulose but not hemicellulose. Hydrolysis of corn fiber pretreated with alkali under similar conditions by enzymatic means gave similar results. Hemicellulose and starch components were converted to monomeric sugars by dilute H2SO4 pretreatment (0.5-1.0%, v/v) at 121 degrees C. Based on these findings, a method for pretreatment and enzymatic saccharification of corn fiber is presented. It involves the pretreatment of corn fiber (15% solid, w/v) with dilute acid (0.5% H2SO4, v/v) at 121 degrees C for 1 h, neutralization to pH 5.0, then saccharification of the pretreated corn fiber material with commercial cellulase and beta-glucosidase preparations. The yield of monomeric sugars from corn fiber was typically 85-100% of the theoretical yield.

AB:   Waxy wheat (Triticum aestivum L.) lacks the waxy protein, which is also known as granule-bound starch synthase I (GBSSI). The starch granules of waxy wheat endosperm and pollen do not contain amylose and therefore stain red-brown with iodine. However, we observed that starch from pericarp tissue of waxy wheat stained blue-black and contained amylose. Significantly higher starch synthase activity was detected in pericarp starch granules than in endosperm starch granules. A granule-bound protein that differed from GBSSI in molecular mass and isoelectric point was detected in the pericarp starch granules but not in granules from endosperm. This protein was designated GBSSII. The N-terminal amino acid sequence of GBSSII, although not identical to wheat GBSSI, showed strong homology to waxy proteins or GBSSIs of cereals and potato, and contained the motif KTGGL, which is the putative substrate-binding site of GBSSI of plants and of glycogen synthase of Escherichia coli. GBSSII cross-reacted specifically with antisera raised against potato and maize GBSSI. This study indicates that GBSSI and GBSSII are expressed in a tissue-specific manner in different organs, with GBSSII having an important function in amylose synthesis in the pericarp.

AB:   S-Adenosyl-L-methionine:L-methionine S-methyltransferase (MMT) catalyzes the synthesis of S-methyl-L-methionine (SMM) from L-methionine and S-adenosyl-L-methionine. SMM content increases during barley (Hordeum vulgare L.) germination. Elucidating the role of this compound is important from both a fundamental and a technological standpoint, because SMM is the precursor of dimethylsulfide, a biogenic source of atmospheric S and an undesired component in beer. We present a simple purification scheme for the MMT from barley consisting of 10% to 25% polyethylene glycol fractionation, anion-exchange chromatography on diethylaminoethyl-Sepharose, and affinity chromatography on adenosine-agarose. A final activity yield of 23% and a 2765-fold purification factor were obtained. After digestion of the protein with protease, the amino acid sequence of a major peptide was determined and used to produce a synthetic peptide. A polyclonal antibody was raised against this synthetic peptide conjugated to activated keyhole limpet hemocyanin. The antibody recognized the 115-kD denatured MMT protein and native MMT. During barley germination, both the specific activity and the amount of MMT protein increased. MMT-specific activity was found to be higher in the root and shoot than in the endosperm. MMT could be localized by an immunohistochemical approach in the shoot, scutellum, and aleurone cells but not in the root or endosperm (including aleurone).

AB:   The influence of extrusion processing in the presence of corn on the quantity and quality of genistein, daidzein, and their respective beta-glucoside, acetyl glucoside, and malonyl glucoside derivatives was evaluated. Products of 100% soy (textured) and a blend of 20% soy protein concentrate (SPC) and 80% corn meal (direct-expanded) were extruded, with evaluations before and after extrusion. In addition, a 3 x (3 x 3) split-plot factorial experiment investigated the influence of barrel temperature (110, 130, 150 degrees C), moisture content (22, 24, 26%), and relative residence time (1, 0.8, 0.6) on extruder response and isoflavone profile. The extrusion barrel temperature had the most influence on isoflavone profile, especially decarboxylation of the malonyl beta-glucoside, followed by the moisture content. The amount of extractable isoflavones decreased after extrusion for both the SPC and SPC/corn meal blend when extracted with 80% aqueous methanol but remained approximately the same when first hydrated with water before extraction. However, initially hydrating with water produced enzymatic glycolysis in the unextruded samples, increasing the aglycons dramatically.

AB:   Six 100 ppm fumonisin B1 (FB1) solutions were prepared by dissolving pure standard in six different solvents containing SO2. Two of the solvents contained 0.2 or 0.4% SO2 in distilled water. The other four solvents were obtained by steeping corn kernels at 60 degrees C in a 0.2% SO2 aqueous solution for 6, 12, 24, or 48 h. After the addition of FB1, all solutions were maintained at 60 degrees C for 7 days. Fumonisin B1 content in each solution was determined in triplicate by HPLC. Steeping corn kernels in 0.2% solution at 60 degrees C for 6 h seems to be the most effective treatment to decrease the amount of FB1.

AB:   In 19 wheat-milling fractions total pentosan content, calculated as 0.88 x (% L-arabinose + % D-xylose), varied between 1.44 and 30.66% on dry matter (dm). It increased with ash content once the latter exceeded 0.6% (dm basis). Water-extractable arabinoxylans were recovered by saturating water extracts to 65% ethanol. Their contents in the milling fractions varied between 0.35 and 1.38%, and above 0.6% ash content also increased with this parameter. Their L-arabinose-to-D-xylose ratios ranged between 0.65 and 0.39, with the lowest values found for the fractions with highest ash content, indicating that the ash-rich tissues contain more arabinoxylans that are less branched. 1H NMR spectroscopy revealed that the decrease in L-arabinose-to-D-xylose ratio was accompanied by an increase in unsubstituted xylose residues and a decrease in disubstituted xylose residues, while the contents of monosubstituted xyloses were virtually constant.

AB:   Water shortage produced an early and large stimulation of acid-soluble invertase activity in adult maize leaves whereas cell wall invertase activity remained constant. This response was closely related to the mRNA level for only one of the invertase gene (Ivr2), encoding a vacuolar isoform. In parallel, four quantitative trait loci (QTLs) were detected for invertase activity under control and nine under stressful conditions. One QTL in control and one in stressed plants was located near to the Ivr2 gene on chromosome 5. Other QTLs for invertase activity were found close to carbohydrate QTLs; some of them formed 'stress clusters'.

AB:   For identification of genes involved in embryogenesis in the model cereal rice, we have constructed a collection of cDNA libraries of well-defined stages of embryo development before, during and after organ differentiation. Here, we focus on the possible role of KNOX (maize Knotted1-like) class homeobox genes in regulation of rice embryogenesis. Three types of KNOX clones were identified in libraries of early zygotic embryos. Two of these, Oskn2 and Oskn3, encode newly described KNOX genes, whereas the third (Oskn1) corresponds to the previously described OSH1 gene. In situ hybridizations showed that during the early stages of embryo development, all three KNOX genes are expressed in the region where the shoot apical meristem (SAM) is organizing, suggesting that these genes are involved in regulating SAM formation. Whereas OSH1 was previously proposed to function also in SAM maintenance, Oskn3 may be involved in patterning organ positions, as its expression was found to mark the boundaries of different embryonic organs following SAM formation. The expression pattern of Oskn2 suggested an additional role in scutellum and epiblast development. Transgenic expression of Oskn2 and Oskn3 in tobacco further supported their involvement in cell fate determination, like previously reported for Knotted1 and OSH1 ectopic expression. Whereas Oskn3 transformants showed the most pronounced phenotypic effects during vegetative development, Oskn2 transformants showed relatively mild alterations in the vegetative phase but a more severly affected flower morphology. The observation that the KNOX genes produce similar though distinct phenotypic reponses in tobacco, indicates that their gene products act on.

AB:   A model consisting of a plug flow reactor (PFR) in series to a continuous stirred tank reactor with a fraction of flow held up in a stagnant dead volume has been developed. The model was tested against the experimental measurements obtained from a single screw extruder fed with rice flour and the literature data. The fitting of the model to the experimental data was very good with correlation coefficients (r2) higher than 0.97. Through the paired comparison, no difference exists between the literature data and the model at the 95% confidence level. Feed rate and screw speed showed strong effects on the fraction of PFR (P) which was in the range of 0.36-0.65. The fraction of dead volume (d) varied from 0.04 to 0.16. Both the mean residence time and P were further expressed as functions of the screw speed and feed rate. With the average value of d for a specific screw profile, the residence time distributions were estimated from the operating conditions. The results demonstrated that no difference existed between the calculated values and experimental data at the 95% confidence level.

AB:   Yellows maize grits were extrusion cooked in a conical, counter-rotating twin-screw extruder, at different barrel temperatures (140-180 degrees C), feed moistures (13-17% wet basis), feed rates (38-52 kg/h), and screw speeds (60-80 rpm). Residence time distribution was measured by a dye tracer technique. The kinetics of colour changes during extrusion cooking was studied using the CIE Lab colour parameters (L* a* b* scale) as physical parameters. The lightness (L*) and redness (a*) were markedly dependent on barrel temperature and feed moisture content, whereas screw speed was not significant. The yellowness parameter (b*) was only slightly dependent on extrusion variables. A zero order rate equation was used to model the kinetics of colour changes. The kinetic rate constants for the change in lightness and redness were dependent on product temperature and feed moisture content. The activation energy, according to the Arrhenius equation, was 65 and 74 kJ/mol for lightness and redness, respectively. The lightness parameter (L*) showed marked changes due to extrusion cooking and was the best parameter in the modelling of extrudate browning kinetics.

AB:   We consider a problem, that is basic to perception measurement: an artificial system that mimics the integration of perceptual information into a proposed framework performed by the human senses. The paper presents a method for optimising complex information from one single sensor that is indirectly based on the human measurement capability, in the mixing process of dough. We propose a method to measure, analyse and correlate sensor information. This technique is exemplified by an industrial application, where the influence of the properties of the human senses on the rheological behaviour of wheat flour dough is estimated and has further been studied in the dynamic mixing process. It is shown that, by dynamic measurements on the mixing machine, the complex behaviour of the mixing process could clearly be followed. However, by implementing human knowledge and experience to the sensor system we manage to adapt a process that works with human preferences. The system's ability to optimise various types of bread formulae and different types of wheat flour is also described. An additional benefit is the possibility, by calculations, to predict the behaviour of the wheat flour dough process.

The cooking time is reduced by at least 30%. The process saves about 40% energy and can be easily adopted by primary processors in developing countries. The rices have been organoleptically evaluated and found acceptable.

AB:   In west Asia, it is traditional for sheep to gain body condition when low-cost native pastures are available and to mobilize reserves thus built up at other times. With diminishing shares of native pasture, crop by-products and food grains are increasing in sheep diets, and facilitate feeding for constant body condition. In a 2 X 2 X 2 factorial experiment, 48 Awassi ewes were individually fed indoors, nursed single lambs for 42 days, and were hand-milked from day 29 after lambing. Dietary treatments were imposed at different times: level of feeding (i) in the last 24 days of pregnancy (Pconst v. Pmob) (ii) in days 18 to 60 after lambing (Lconst v. Lmob), and (iii) level of fibre in days 60 to 102 after lambing (Fhigh v. Flow). Rations Pconst, Lconst, Flow and Fhigh were calculated to maintain body condition. Ehigh provided the calculated maximum ingestible quantity of barley straw and Flow provided 0(.)08 kg barley straw per kg diet. Live weights (M) of ewes and lambs, milk yield and milk quality were recorded. With Pconst, and Pmob (0(.)51 and 0(.)33 MJ metabolizable energy (ME) per kg M0(.)75 per day), M gains were 140 and 23 g/day (P < 0(.)001). Lamb birth mass and subsequent maternal milk yield were not affected. With Lconst and Lmob (0(.)81 and 0(.)61 MJ ME per kg M0(.)75 per day), M changes were -28 and -70 g/day (P < 0(.)001) and milk yields (calculated in part from lamb growth) were 1042 and 892 g/day (P < 0(.)01). Fhigh and Flow (385 and 170 g acid-detergent fibre per kg dry matter) were compared in a two-period change-over design experiment. Milk yields were similar (414 and 427 g/day), milk fat concentrations were 64(.)8 and 72(.)9 g/kg (P < 0(.)001) and milk.
       fat yields were 26(.)5 and 31(.)1 g/day (P < 0(.)001) but solids-not fat and protein yields were not affected. There were benefits and costs in manipulating body reserves in Awassi sheep. M at lambing affects milk yield and body condition around mating is known to improve lambing rate. The existence of body reserves also allows body condition to be lost in late pregnancy and early lactation without affecting health or apparent welfare, which simplifies management of pregnant ewes, permits feeding of milk fat-increasing high-fibre diets but the ME to maintain increased body reserves must not be ignored.

AB:   The disappearance of neutral-detergent fibre (NDF) from six fibrous foods (lucerne hay, NaOH-treated barley straw, olive leaves, paprika meal, soya-bean hulls and sunflower hulls) when incubated in the rumen of sheep in nylon bags was investigated. Source of fibre, time of incubation and its interaction had a significant (P < 0(.)001) effect on NDF degradation. Stepwise regression analysis showed that the best single predictor for NDF degradation rate was the hemicellulose fraction of NDF (HEMndf). The variables selected to predict potential degradability and degradability of NDF at 72 h were the proportions of acid-detergent lignin in NDF (ADLndf, first step) and of acid detergent cutin in ADL (ADCadl, second step). For NDF degradability at 12 h, the variables selected were the proportions of HEMndf, ADLndf and ADCadl, in the first, second and third step, respectively. The results showed that ADC is an important component to understand NDF degradability at both 12 and 72 h.

AB:   A 28-day experiment with 12 9-month-old cattle (275 kg initial weight, M1), used a 2 X 2 arrangement of treatments to compare the effect of doubling the ad-libitum quantity of long barley straw offered daily (25 or 50 g dry matter (DM) per kg M1) and sex/genotype (Limousin X Friesian steers or Friesian heifers) on intake and selection. All animals received a protein concentrate at 20 g DM per kg M1(0(.)75) per day. Prior to the experiment the cattle had grazed for 6 months and were given 110 pre-experimental change-over period. On day 1 animals were weighed (M1), allocated to treatment and penned individually. Animals were weighed on day 28 (M2). Doubling the amount offered did not affect straw intake (g DM per kg M3 per day; M3 = mean of M1 and M2) during days 22 to 28 (steers: 17(.)9, 17(.)2; heifers 14(.)3, 13(.)3; s.e. 0(.)50) but increased the proportion (g DM per kg DM offered) refused (steers: 258, 635; heifers: 412, 721; s.e. 22). During days 22 to 28, at each level of offer (25, 50), refused straw contained (g DM per kg DM) less leaf-plus-sheath than offered straw (25 g steers: 251, 430, s.e. 16(.)7; 50 g steers: 393, 450, s.e. 19(.)7; 25 g heifers: 304, 420, s.e. 7(.)2; 50 g heifers: 405, 446, s.e. 9(.)6). The sex/genotype effect on intake was attributed to differences in growth potential. Straw intakes increased significantly over the first 14 days, but there were no differences between days 15 to 21 and days 22 to 28. It is concluded that all excess feeding strategy, involving a doubling of the ad libitum amount of barley straw offered did not result in growing cattle consuming more straw, in contrast to published results with sheep and goats. However, the cattle did show a.
       limited ability to selectively consume leaf-plus-sheath in preference to stem but the improvement in diet digestible organic content (estimated in vitro) was presumably insufficient to stimulate intake.

AB:   The objective was to elucidate the influences of two analytical methods, which employed neutral detergent or enzymes, on the digestion of carbohydrate fractions in the rumen and post-rumen of steers. Structural carbohydrates in diets and digesta were directly measured using both procedures and the contents of non-fibre carbohydrates (NFC) and non-fibre non-starch polysaccharides (NFSP) were estimated by subtracting the structural carbohydrates and other components from the organic matter. Carbohydrate sources were Italian ryegrass and rolled barley in the control diet and, in each of other three diets, Italian ryegrass and rolled barley plus either beet pulp, citrus pulp or soya-bean hulls. All diets contained similar proportions of dry matter as crude protein, structural carbohydrates and NFC but the starch proportion of the NFC was different in each diet, as follows: control (0(.)62), beet pulp (0(.)48), citrus pulp (0(.)30) and soya-bean hulls (0(.)63). Four Holstein steers with ruminal, duodenal and ileal cannulas were offered the four diets in a 4 X 4 Latin-square design. Estimated digestibilities of the structural carbohydrates in the rumen and the whole tract were greater (P < 0(.)01) when the detergent method was used than when the enzymatic method was used. The maximal difference in the ruminal digestion among the four diets was only 0(.)05 by the detergent method but 0(.)17 by the enzymatic method. Conversely, the digestibility of NFC in the rumen, as estimated from the detergent structural carbohydrates was less (P < 0(.)01) than that estimated from enzymatic structural carbohydrates with no evident differences among the four diets. Starch digestibility.
       in the rumen was extensive for all diets but the ruminal digestibility of NFSP was much lower in the control and soya-bean hull diets, especially when it was estimated using the detergent method. The duodenal flow of microbial protein was greater (P < 0(.)05) for the beet pulp and citrus pulp diets than for the control. The acetate concentration of the ruminal fluids ranged from 84 for the control diet to 128 mmol/l for the soya-bean hulls diet. The digestion of carbohydrate fractions and the fermentation characteristics in the rumen suggested that the enzymatic method is the more appropriate method for fractionating carbohydrates.

AB:   The oil stability index (OSI) and peroxide value (PV) were used to determine the quality of oil blends. The quality of soybean oil (SBO) blended with other refined, bleached and deodorized (RBD) oils was between the quality of SBO and the RBD oils selected for blending. However, crude peanut oil blended with SBO diminished the quality of SBO while crude sesame oil with unique antioxidants improved the quality of SBO blends. To study the effect of fatty acid composition (FAC) on the oxidative stability of oil blends, 21 oil blends were prepared by using 7 commercial RBD oils which were re-deodorized and followed by tocopherol adjustment. A mathematical model describing the relationship between OSI and FAC of 21 oil blends was obtained as follows: OSI (h) = 7.5123 + %C16:0 x (0.2733) + %C18:0 x (0.0797) + %C18:1 x (0.0159) + %C18:2 x (-0.1141) + %C18:3 x (-0.3962), r2 = 0.911. The difference between the values of each predicted and measured OSI were within 10%, which indicated that the oxidative stability of oil blends of any ratio from the 7 RBD oils under study could be predicted by using this model.

AB:   Two bread cultivars and one durum Indian wheat cultivar were evaluated for ash distribution pattern using a McGill No.2 rice polisher. Grains of all the wheat cultivars were debranned for 30, 60, 90 and 120 s and determined for ash content. Ash content progressively decreased with the increase in debranning time. Statistical analysis showed significant differences among cultivars for ash content and weight of grain removed by debranning. Ash determined by a standard method showed a linear relationship with conductivity (R2 value in the range of 0.93-0.99) among the cultivars. The conductivity of extract from whole and debranned grains was found to be highly influenced by extraction time as well as temperature.

AB:   The rheological properties of wheat meal and wheat starch with and without added wheat germ oil (WGO) and of oat flour under low moisture conditions were investigated using a capillary rheometer and the flow behaviour described by the power law model. The consistency coefficient of wheat starch and wheat meal decreased with increase in moisture content from 21% to 28% (wet weight basis) and barrel temperature from 100 degrees C to 125 degrees C and with the addition of WGO to 8%. The flow behaviour index of wheat starch and wheat meal generally increased with this increase in extrusion moisture content and temperature and with the addition of WGO. Wheat starch showed the highest consistency coefficient and oat flour showed the lowest under identical set extrusion conditions of these temperatures and moistures. Both power law indices for oat flour showed a less well defined change for the same range of moisture and temperature. The effect of WGO addition to wheat starch or meal to the 8% level was to reduce their viscosities towards the value observed for oat flour. The power law indices varied with die diameter indicating possible wall slip.

AB:   Particle bombardment has been used to transform three cultivars (L35, Ofanto, Svevo) and one breeding line (Latino X Lira) of durum wheat (Triticum turgidum L. var. durum). These varieties were co-transformed with plasmids containing selectable and scorable marker genes (bar and uidA) and plasmids containing one of two high-molecular-weight (HMW) glutenin subunit genes (encoding subunits 1Ax1 or 1Dx5). Ten independent transgenic lines were recovered from 1683 bombarded scutella (transformation efficiency thus 0.6%). Five lines expressed either subunit 1Dx5 or 1Ax1 at levels similar to those of endogenous subunits encoded on chromosome 1B. To identify the effects of the transgenes on the functional properties of grain, three lines showing segregation for transgene expression were used to isolate sibling T2 plants which were null or positive for the transgene product. Analysis of these plants using a small-scale mixograph showed that expression of the additional subunits resulted in increased dough strength and stability, demonstrating that transformation can be used to modify the quality of durum wheat for bread and pasta making.

AB:   Proteinase inhibitors have been used to increase resistance to insect pests in transgenic plants. A cDNA clone encoding a multi-domain proteinase inhibitor precursor from Nicotiana alata (Na-PI) was transferred into tobacco and peas under the control of a promoter from a ribulose-1,5-bisphosphate carboxylase small subunit gene. The Na-PI precursor was cleaved in the leaves of transgenic tobacco and peas, and Mr 6000 polypeptides accumulated to levels of 0.3% and 0.1%, respectively, of the total soluble protein. The Na-PI cDNA segregated as a dominant Mendelian trait and was stably transmitted for at least two generations of both species. Helicoverpa armigera larvae that ingested tobacco or pea leaves containing Na-PI exhibited higher mortality or were delayed in growth and development relative to control larvae.

AB:   The development of genetic transformation technology for plants has stimulated an interest in using transgenic plants as a novel manufacturing system for producing different classes of proteins of industrial and pharmaceutical value. In this regard, we report the generation and characterization of transgenic maize lines producing recombinant aprotinin. The transgenic aprotinin lines recovered were transformed with the aprotinin gene using the bar gene as a selectable marker. The bar and aprotinin genes were introduced into immature maize embryos via particle bombardment. Aprotinin gene expression was driven by the maize ubiquitin promoter and protein accumulation was targeted to the extracellular matrix. One line that showed a high level of aprotinin expression was characterized in detail. The protein accumulates primarily in the embryo of the seed. Southern blot analysis showed that the line had at least 20 copies of the bar and aprotinin genes. Further genetic analysis revealed that numerous plants derived from this transgenic line had a large range of levels of expression of the aprotinin gene (0-0.069%) of water-soluble protein in T2 seeds. One plant lineage that showed stable expression after 4 selfing generations was recovered from the parental transgenic line. This line showed an accumulation of the protein in seeds that was comparable to the best T2 lines, and the recombinant aprotinin could be effectively recovered and purified from seeds. Biochemical analysis of the purified aprotinin from seeds revealed that the recombinant aprotinin had the same molecular weight, N-terminal amino acid sequence, isoelectric point, and trypsin inhibition activity as native.
       aprotinin. The demonstration that the recombinant aprotinin protein purified from transgenic maize seeds has biochemical and functional properties identical to its native counterpart provides a proof-of-concept example for producing new generation products for the pharmaceutical industry.

AB:   Wild abortive cytoplasmic male sterility has been extensively used in hybrid seed production in the tropics. Using protoplast fusion between cytoplasmic male sterile and fertile maintainer lines; we report here, transfer of wild abortive cytoplasmic male sterility to the nuclear background of RCPL1-2C, an advance breeding line which also served as maintainer of this cytoplasm. In total, 27 putative cybrids between V20A and RCPL1-2C and 23 lines between V20A and V20B were recovered and all of them were sterile. DNA blots prepared from the mitochondrial DNA of the cybrid lines from both the sets were probed with orf155 that is known to exhibit polymorphism between the mitochondrial DNA of the male-sterile and fertile maintainer lines. Hybridization of orf155 to 1.3 kb HindIII-digested mitochondrial DNA fragment of the cybrids showed transfer of mitochondrial DNA from wild abortive cytoplasmic male-sterile line to the maintainers, viz. RCPL1-2C and V20B. Expression of male sterility was confirmed by the presence of sterile pollen grains and the lack of seed setting due to selfing in all the cybrid lines. These cybrids, on crossing with respective fertile maintainers set seeds that in turn, produced sterile BC1 plants. DNA blots from HindIII-digested mitochondrial DNA of these BC1 plants when probed with orf155 again exhibited localization of orf155 in wild abortive cytoplasm-specific 1.3 kb HindIII-digested mitochondrial DNA fragments. This demonstrated that the cytoplasmic male sterility transferred through protoplast fusion retained intact female fertility and was inherited and expressed in BC1 plants. Fusion-derived CMS lines, on pollination with pollen.
       grains from restorer, showed restoration of fertility in all the lines. The results demonstrate that protoplasts fusion can be used for transferring maternally inherited traits like cytoplasmic male sterility to the desired nuclear background which can, in turn, be used in hybrid seed production programme of rice in the tropical world.

AB:   Coeliac disease (CD) is an inflammatory disorder of the upper small intestine in which gluten acts as an essential factor in its pathogenesis. Although it is generally accepted that cereal protein activation of the immune system is involved in CD progression, a non-immunomediated cytotoxic activity of gliadin-derived peptides on the jejunal/duodenal tract cannot be excluded. In this work considering that (a) little has been reported about the intracellular metabolic events associated with gliadin toxicity, and (b) an important role for free radicals in a number of gastrointestinal disease has been demonstrated, we investigated the in vitro effects of gliadin-derived peptides on redox metabolism of Caco-2 intestinal cells during a kinetic study in which cells were exposed to peptic-tryptic digest of bread wheat up to 48 h. We found that the antiproliferative effects displayed by gliadin exposure was associated with intracellular oxidative imbalance, characterised by an increased presence of lipid peroxides, an augmented oxidised (GSSG)/reduced (GSH) glutathione ratio and a loss in protein-bound sulfhydryl groups. Significant structural perturbations of the cell plasma membrane were also detected. Additional experiments performed by using the specific GSH-depleting agent buthionine sulfoximine provide evidence that the extent of gliadin-induced cell growth arrest critically depends upon the 'basal' redox profile of the enterocytes. On the whole, these findings seem to suggest that, besides the adoption of a strictly gluten-free diet, the possibility for an adjuvant therapy with antioxidants may be considered for CD patients.

AB:   The present paper is intended for removing inconsistencies from available information concerning the interrelationhips of nitrogen (N) and amino acids in seeds (or grains). It consists of a critical survey of data reported in a series of papers by Mosse and collaborators (see Mosse and Huet, Sci. Aliments 1990, 10, 151 for review). These authors contended for perfectly linear relationships (Ai = aiN + bi) to hold between N and amino acid i (g(100 g seed dry matter) for seeds of a given species on the basis of correlation coefficient (r) found to be close to 1. Three linear regressions are called upon to analyze variations in the amino acid compositions of 33 samples of pea seeds. The regression Ci (g amino acid i/16gN) = 16ai + 16biN(-1), not used customarily, is the more amenable to accommodate all the facts in pointing out values significantly lower than 1 for ri2, and parameters ai and bi similar to those found with the regression Ai = NCi/16 = aiN + bi whose ri2 values, very close to 1, are overestimated on account of the presence of N in both sides of equation and sampling limited in number. Examination of variations in lysine content of maize grains as a function of N shows that the phenotypic variations for a given genotype are a poor fit to the linear relationship Alys = aN + b available in the literature, as determined from 153 commercial samples. It is concluded that linear N-amino acid relationships hold only approximately for predicting amino acid composition of seed of a given species from its N content.

AB:   This research evaluated the direct and interactive effects of atmospheric CO2 and soil NO3(-) availability on growth and biomass partitioning of quaking aspen (Popular tremuloides Michx.), red oak (Quercus rubra L.), and sugar maple (Acer saccharum Marsh.). In the split split plot experimental design, NO3(-) availability (low and high) and tree species were nested in two levels of atmospheric CO2 (ambient, 355 microliters/L; elevated, 650 microliters/L). Seedlings were grown for 57 days in environmental control rooms. Increased CO2 and NO3(-) availability positively and (mostly) independently influenced total growth and relative growth rates. Moderate to weak interactions between CO2 and NO3(-) for several growth parameters (e.g., leaf production, shoot length, root collar diameter) in some species indicated an enhanced response to CO2 enrichment under conditions of high NO3(-) availability. Interactive effects were most pronounced in aspen. Seedling growth and allocation responses to CO2 and NO3(-) were frequently species specific and associated with successional status. For example, proportional increases in growth in response to elevated CO2 were greatest for sugar maple and least for quaking aspen, whereas the converse was true with respect to response to high NO3(-) availability. This research indicates that the impact of enriched CO2 atmospheres on forest communities will be influenced by both nutrient availability and unique species characteristics.

AB:   Availability of soil nitrogen, soil moisture, and light were examined, along with the growth, biomass allocation, and leaf nitrogen concentration of naturally established Acer saccharum Marsh. seedlings, in the understories of 12 forest sites in northern Wisconsin. The sites represented a nutrient and moisture gradient (poor to rich) according to a habitat classification system. We asked (1) Are seedling growth rates, biomass allocation patterns, and leaf nitrogen related to soil water and nitrogen availability? and (2) Do soil resource rankings predicted by habitat classifications mirror our direct observations? Across sites compared in a low-light data set (plots with < 5% canopy openness), rich sites had 2- to 4-fold higher seedling growth, percent leaf nitrogen, nitrogen mineralization rates, and nitrification rates than poor sites. Seedling growth in low light correlated (P greater than or equal to 0.05) positively with nitrification, total nitrogen mineralization, percent leaf nitrogen, soil moisture, and organic carbon, and negatively with fine root density. In multiple regression, soil moisture (P = 0.033) and nitrification (P = 0.015) together explained 79% of the variation in growth. Thus, seedling growth in shade was enhanced on richer sites in part because of higher nitrate N and water availability. This has potential implications for forest dynamics, since the probability of sugar maple becoming the dominant woody regeneration in any given understory may be partially dependent upon the level of soil resources.

AB:   Optimization models are useful in ascertaining optimum parameters as they relate to a particular response. Ethanol production with different cellulase-systems and substrate concentrations were subjected to this model and the results revealed that crude unextracted cellulase-systems are more efficient than crude extracted cellulase-systems in producing hydrolysates for ethanol production with Pichia stipitis (Y-7124), Saccharomyces cerevisiae (AT 60868) and their mixture. Response surface plots showed that for 80-90% of high concentrations of delignified wheat straw up to 11% could be converted into ethanol by simultaneous hydrolysis with enzyme loading of 16 IU/mL and fermentation with P. stipitis. P. stipitis was found to be the most suitable yeast for the fermentation of mixed hexose and pentose sugars in the wheat straw hydrolysate.

AB:   Three treatments, exogenous amylase, endogenous amylase (use of germinating cereal on untreated flour, also known as power flour or kimea treatment) and germination, were used to reduce the viscosity of the cereal component of a cowpea-sorghum weaning food. Proximate composition of seed samples and flour blends (ratio 1:1) showed that the samples contained 12-13% protein, 1-2% fat and 352-364 kcal/g. The relative viscosity, reconstitution time, sensory and nutritional properties of the samples given different treatments were evaluated. Viscosity reduction was achieved maximally by the use of exogenous amylase. The sample treated with endogenous amylase had the highest PER (2.1) and digestibility (98.7%). Digestibility values were, however, not significantly different (P less than or equal to 0.05) from one another. The germinated sample had the lowest reconstitution time (180 s.). A commercial weaning food 'Nutrend ' (Nestle foods) possessed better sensory properties but poorer reconstitutability and viscosity characteristics than treated samples. There is need to improve the sensory characteristics of these products to ensure better consumer acceptance.

AB:   When etiolated angiosperm seedlings break through the soil after germination, they are immediately exposed to sunlight, but at this stage they are unable to perform photosynthesis. In the absence of chlorophyll a and chlorophyll b, two other porphyrin species cooperate as the basic light-harvesting structure of etiolated plants. Protochlorophyllide a and protochlorophyllide b form supramolecular complexes with NADPH and two closely related NADPH:protochlorophyllide oxidoreductase (POR) proteins--PORA and PORB--in the prolamellar body of etioplasts. Here we report that these light-harvesting POR-protochlorophyllide complexes, named LHPP, are essential for the establishment of the photosynthetic apparatus and also confer photoprotection on the plant. They collect sunlight for rapid chlorophyll a biosynthesis and, simultaneously, dissipate excess light energy in the bulk of non-photoreducible protochlorophyllide b. Based on this dual function, it seems that LHPP provides the link between skotomorphogenesis and photosynthesis that is required for efficient de-etiolation.

AB:   The non-Newtonian behavior and dynamic viscoelasticity of rice starch (Nihonbare; amylose content, 15.8%) solutions were measured with a rheogoniometer. A gelatinization of Nihonbare starch occurred above 3.0% after heating at 100 degrees C for 30 min. The Nihonbare starch showed shear-thinning behavior at a concentration of 2.0%, but plastic behavior above 3.0% at 25 degrees C. The viscosity of Nihonbare starch at a concentration of 2.0% solution decreased gradually with increase in temperature from 10 to 55 degrees C, then it stayed at a constant value with further increase in the temperature. However, for 4.0% solution, rapid decrease in the viscosity was observed after the temperature reached 25 degrees C up to 50 degrees C, then it stayed at a constant value. The dynamic modulus of Nihonbare starch stayed at a constant value during increase in the temperature at 4%. The tan delta of the starch showed low values, 0.28, at low temperature range and stayed at a constant up to 30 degrees, then it increased a little with increasing temperature. A little decrease of dynamic modulus of Nihonbare starch was observed at low temperature range upon addition of urea (4.0 M). The dynamic modulus, however, decreased rapidly when the temperature reached 50 degrees C, which was estimated to be a transition temperature. The dynamic modulus also decreased rapidly in 0.10 M NaOH solution above 50 degrees C. A possible mode of intermolecular hydrogen bonding between amylose and amylopectin molecules of Nihonbare starch is proposed. The short chains (A and B1) of the amylopectin molecules may take part in the intermolecular association in aqueous solution.

AB:   This study specifies a procedure to quantify the determinants of sustainable crop production, and applies the method to wheat cultivation in the Tarai of Nepal. Three aspects of sustainability were considered. First, the fertility of the land was found to have deteriorated owing to long-term practices incompatible with soil and drainage conditions. Three-quarters of the farmers had reduced land fertility and for one-third of them the wheat yield was at least 20% lower than for farmers who applied farmyard manure to every crop and adopted a rotation consistent with soil and drainage conditions. Secondly, the study found that it was possible to improve resource-use efficiency in wheat production to give 25% higher production at current levels, type, and quality of farm resources. Resource-use efficiency was significantly related to farm management practices such as crop stand, variety, disease, and land preparation quality. and socio-economic factors such as off-farm job opportunities, poor plot accessibility, and migration. Thirdly, the increasing population pressure on land, decreasing livestock number per cropped area, and diminishing fuel wood sources, significantly reduced farm-based nutrient cycling because farmyard manure had to be used for fuel. This had implications for the higher use of the fossil-based inputs in crop production.

AB:   The short-run effects of fungicide application on economic risk and the effects of risk on fungicide use in Swiss wheat production are empirically explored. A quadratic production function model is developed. With the help of the moment-based approach, marginal contributions of fungicides (representing controlled inputs) and of rain (representing uncontrolled inputs) to the variances of yield and revenue are analyzed. It is not possible to show risk-reducing effects of fungicides on yield or revenue. At low rain quantities during the vegetation period fungicides have a statistically significant risk-increasing effect on revenue. Increasing risk leads Swiss wheat growers to use more fungicide. This increase is statistically significant at higher levels of revenue. For example, when risk is doubled fungicide inputs are raised by 44% at the highest revenue quartile.

Deoxynivalenol (DON), 3- and 15-acetyl-deoxynivalenol (3-, 15-ADON), nivalenol (NIV), fusarenon-X (FUS-X), T-2 toxin (T-2), HT-2 toxin (HT-2) and diacetoxyscirpenol (DAS) were determined by gas chromatography with mass selective detection (GC-MS), zearalenone (ZEA), alpha and beta-zearalenol (alpha-beta-ZOL) by GC-MS or by HPLC. DON was the major toxin with incidences at 49-85% and mean levels in positive samples of 52-302 microgram/kg. Incidences of ZEA, 3-ADON, NIV, HT-2, and T-2 were at 20-37, 0-30, 18-67, 0-29, and 27-61%, respectively, with mean levels in positive samples at 8-25, 5-63, 11-192, 205-296, and 20-244 microgram/kg, respectively. alpha- and beta-ZOL and DAS were not detected in any sample. 15-ADON and FUS-X were assayed in samples from 1987, 1991 and 1992. 15-ADON was detected in 9, 4 and 0% of samples, with an average of 9 and 18 microgram/kg, respectively; FUS-X was not detected. The incidence and levels of toxins varied from year to year. The correlation between the occurrence of toxins and precipitation is discussed.

AB:   A glucose tolerance study performed using 60 malnourished children of interior parts of rural Maharashtra indicated that 41% of the malnourished children showed an imparied glucose tolerance (IGT) and 59% a normal glucose tolerance (i.e. mean fasting glucose levels as: 130.2 +/- 12.6 and 88.7 +/- 7.4 mg/dl respectively). Dietary analysis of the groups indicated that the food energy intake of the tolerant group though low when expressed as percent RDA i.e. 36.1% was significantly higher than the intolerant group i.e. 31.5% (p < 0.001). The food energy intake of the controls was comparable with the RDA. The daily protein intake of the controls and tolerant group was also significantly higher than the intolerant group (p < 0.001 and p < 0.1). On comparing the intake of staple millets, it was seen that the percent calories from sorghum in the IGT group was significantly higher than the control and tolerant group (p < 0.001 and p < 0.001). Intake of sulphur containing amino acids of the IGT group was significantly lower than the tolerant group and controls i.e. 0.382, 0.693 and 3.385 g respectively (p < 0.001 and p < 0.001). These amino acids are essential for detoxification of dietary toxins.

AB:   The nutritional quality of six baby foods based on milk or milk-cereals consumed in Saudi Arabia, was evaluated by means of chemical and biological assays. The baby foods (milk-based vs milk-cereal) provided (per 100 kcal) protein (5.0-5.3 g vs 2.8-3.9 g), fat (5.5-5.6 g vs 2.0-4.5 g), carbohydrates (7.2-7.4 g vs 12.1-16.5 g), Ca (188-200 mg vs 115-180 mg), P (146-153 mg vs 80-105 mg) and Fe (0.18-0.20 mg vs 1.5-2.0 mg). Metabolizable energy (ME) varied between 476-480 kcal vs 390-454 kca1/100 g. The content of linoleic acid were lower and saturated fatty acids were higher in milk-based foods than milk-cereal blends. Most of the baby foods were inadequate in linoleic acid to meet the Codex requirements. An imbalance of calories from protein, fat and carbohydrates was found. The true protein digestibility (TD), net protein utilization (NPU) and net dietary protein calorie percent (NDp cal %) in milk-based vs milk-cereal blends ranged from 94-95% vs 92-95%, 0.72-0.74 vs 0.72-0.76 and 14.4-16.0% vs 8.4-11.9% respectively. Low protein quality reflects the influence of processing techniques and storage conditions.

AB:   In order to determine the effects of increased soil temperature resulting from global warming on microbiological reactions, a 21-month field experiment was carried out in the Bavarian tertiary hills. The major objective was to focus on N2O releases as either a positive or negative feedback in response to global warming. The soils of a fallow field and a wheat field were heated 3 degrees C above ambient temperature and N2O fluxes were measured weekly from June 1994 to March 1996. During the experimental period, measured temperature differences between the control plots and the heated plots were 2.9 +/- 0.3 degrees C at a depth of 0.01 m and 1.0-1.8 degrees C at a depth of 1 m. Soil moisture decreased with the elevated soil temperatures of the heated plots. The mean differences in soil moisture between the treatments were 6.4% (fallow field) and 5.2%DW (wheat field dry weight, DW), respectively. Overall N2O releases during the experimental period from the fallow field were 4.8 kg N2O-N ha-1 in the control plot against 5.0 kg N2O-N ha-1 in the heated plot, and releases from the wheat field were 8.0 N2O-N ha-1 in the control plot and 7.6 N2O-N kg ha-1 in the heated plot. However, on a seasonal basis, cumulated N2O emissions differed between the plots. During the summer months (May-October), releases from the heated fallow plot were 3 times the rates from the control plot. In the winter months, N2O releases increased in both the fallow and wheat fields and were related to the number of freezing and thawing cycles.

AB:   N2O emissions were periodically measured using the static chamber method over a 1-year period in a cultivated field subjected to different agricultural practices including the type of N fertilizer (NH4NO3, (NH4)2SO4, CO(NH2)2 or KNO3 and the type of crop (rapeseed and winter wheat). N2O emissions exhibited the same seasonal pattern whatever the treatment, with emissions between 1.5 and 15 g N ha-1 day-1 during the autumn, 1656 g N ha-1 day-1 in winter after a lengthy period of freezing, 0.5-70 g N ha-1 day-1 during the spring and lower emissions during the summer. The type of crop had little impact on the level of N2O emission. These emissions were a little higher under wheat during the autumn in relation to an higher soil NO3-content, but the level of emissions was similar over a 7-month period (2163 and 2093 g N ha-1 for rape and wheat, respectively). The form of N fertilizer affected N2O emissions during the month following fertilizer application, with higher emissions in the case of NH4NO3 and (NH4)2SO4, and a different temporal pattern of emissions after CO(NH2)2 application. The proportion of applied N lost as N2O varied from 0.42% to 0.55% with the form of N applied, suggesting that controlling this agricultural factor would not be an efficient way of limiting N2O emissions under certain climatic and pedological situations.

AB:   In the central highlands of Mexico, the vegetation is dominated by mesquite (Prosopis spp.), a leguminous tree or shrub. An experiment was carried out to investigate how cultivating the land and the disappearance of the natural ecosystem affected the biological functioning of the soil. Soil was sampled from under the canopy of isolated (MESQ treatment) and densely growing mesquite trees (DENS treatment), from the surrounding soil not covered by the canopies of the trees (BARE treatment) and from adjacent land cultivated with maize (ARABLE treatment). Soil was characterized and then incubated aerobically for 39 days at 22 +/- 1 degree C and CO2, N2O production, microbial biomass C and inorganic N concentrations were monitored. The organic C content was 2.3 times and 1.1 times greater in the MESQ and the BARE treatments, respectively, than in the ARABLE treatment, while microbial biomass C was 3.5 times and 1.3 times greater. The microbial biomass activity as expressed by CO2 production was 5.9 times and 3.9 times greater in the MESQ and the BARE treatments, respectively, than in the ARABLE treatment, while N mineralization, as witnessed by the increase in NO3- concentrations, was 3.4 times and 1.7 times greater. No significant amounts of N2O were produced in any of the treatments. It was found that cultivating land characterized by the presence of mesquite changed its characteristics profoundly, and even soil not covered by tree canopies had higher microbial biomass C, and C and N mineralization than soil cultivated with maize and beans.

AB:   The carbon balance is ill defined for agricultural lands so that their role in global C balance cannot be accurately estimated. Changes in agriculture in the last 50 years have resulted in a general increase in grain yields, total net annual production (TNAP), and C input to the soil. Amounts of C returned annually with crop residues on Sanborn Field, one of the oldest experimental fields in the United States, increased after 1950, and this was accompanied by C accumulation in soils. Under wheat monocrop (with mineral fertilizer), C accumulated at a rate of 50 g m-2 year-1. A 3-year rotation (corn/wheat/clover) with manure and nitrogen applications sequestered 150 g m-2 year-1 of C. Total C balance for the wheat and corn production area in the United States, approximated on the basis of these rates, indicates that at least 32 Tg C was sequestered annually during the last 40-50 years.

AB:   The effects of fire on the carbon and nitrogen balance of northern red oak (Quercus rubra L.), white ash (Fraxinus americana L.), and sugar maple (Acer saccharum Marsh.) regeneration were studied in mesic openings in a hardwood forest. A plot in each of four openings was burned in the spring of both 1989 and 1990. Relative growth rate, leaf weight ratio, and concentrations of nonstructural carbohydrate and N were monitored on planted and extant regeneration in burned and nonburned plots. In the absence of fire, extant oak grew as rapidly as ash and maple, but the relative growth rate of planted oak was the lowest of any species or regeneration type. Repeated burning had little effect on the net growth of oak, but it decreased that of ash and maple by 24-85%. Fire effects on relative growth rate were mediated primarily by changes in leaf weight ratio, but the causes underlying these changes were not fully elucidated. They were not consistent with trends in plant nonstructural carbohydrate or N-concentration, which increased or remained unaffected alter fire in all species. In general, oak possessed a number of characteristics, such as a high root starch concentration and an abundance of belowground dormant buds, which appeared to contribute to its post-fire vigor.

AB:   The physiological responses of tree regeneration to fire were studied in openings in a mesic hardwood forest. Gas exchange, nitrogen concentration, and water potential were monitored on foliage of burned and nonburned regeneration of northern red oak (Quercus rubra L.), white ash (Fraxinus americana L.), and sugar maple (Acer saccharum Marsh.) following spring fires in 1989 and 1990. Fire led to a stimulation of light-saturated photosynthesis in foliage of resprouting plants, but the effect varied in magnitude among species. On average, photosynthesis of post-fire maple was 42% higher than that on nonburned plots, with corresponding increases occurring in stomatal conductance and leaf N concentration. In general, fire had a marginal effect on leaf properties of oak and ash. In 1990, the ratio of root area to leaf area and the water potential of sunlit foliage were significantly higher on burned than nonburned plots for maple, but not for oak or ash, paralleling trends in photosynthesis. There was little evidence of a treatment difference in soil moisture or nitrogen availability, and it appeared that fire-induced stimulations in photosynthesis were mediated primarily by changes in intrinsic (e.g., root area/leaf area ratio) as opposed to extrinsic (e.g.. soil moisture) factors governing resource availability to the canopy of post-fire sprouts.

AB:   The influence of fire on the regeneration ecology of northern red oak (Quercus rubra L.) and sympatric tree species was examined in mesic hardwood stands in southwestern Wisconsin. A plot in each of four openings was burned in the spring of 1989 and 1990. Density and height growth of tree regeneration, and leaf area index and percent cover of all plant growth forms were monitored on burned and nonburned plots in both years. Tree height growth was also measured in 1991. Fire substantially decreased tree regeneration density, and grasses and sedges became the most abundant vegetation on burn plots. Post-fire survival varied among the most common tree species. Densities of Acer saccharum Marsh. and Ostrya virginiana (Mill.) K. Koch decreased by more than 80%, while those of Q. rubra and Carya cordiformis (Wangenh.) K. Koch increased or were unaffected. Net 2-year height growth decreased by 65% or more on burn plots for all of the common tree species except Q. rubra and C. cordiformis, which experienced losses of 25-35%. The differential effects of fire on species survival and growth enhanced the competitive status of Q. rubra. In the absence of fire, it was uncertain whether Q. rubra would maintain a dominant or codominant position in the canopy of these developing stands.

AB:   Chemical composition (proximate, minerals, and fatty acids) of semimembranosus (SM) and cardiac muscle from cattle fed grass (G) and grain on grass without (GG) or with (GGP) zeranol implant were determined. The protein content of SM muscle from GG and GGP cattle was higher (p "< or =" 0.05) while the moisture content was lower (p "< or =" 0.05) than that from G cattle. The lipid content of cardiac muscle from GG cattle was higher (p "< or =" 0.05) compared to that of G cattle. Grain supplementation (GG and GGP) increased the potassium level in SM muscle while a decrease was observed in cardiac muscle. Grain supplementation also increased linoleic acid but decreased polyunsaturated (PUFA) fatty acids in both muscles. There was 3 times more PUFA, particularly linolenic and arachidonic acids, in cardiac muscle than in SM muscle irrespective of the feed type. The concentrations of PUFA in SM and cardiac muscle were higher for G cattle than for GG and GGP cattle, which could make muscles from G cattle more prone to oxidation.

AB:   Triticale cv. Beagle 82, cotton cv. McNair 235, and soybean cv. Twiggs were arranged in three cropping sequences to determine the effects of fenamiphos and cropping sequence on nematode population densities and crop yields under conservation tillage for 4 years. The cropping sequences were triticale (T)-cotton (C)-T-C, T-soybean (S)-T-S, and T-C-T-S. Numbers of Meloidogyne incognita second-stage juveniles declined on triticale but increased on cotton and soybean each year. Root-gall indices of cotton and soybean ranged from 1.00 to 1.08 (1 to 5 scale: 1 = 0%, 2 = 1% to 25%, 3 = 26% to 50%, 4 = 51% to 75%, 5 = 76% to 100% of roots galled) each year and were not affected by fenamiphos treatment or cropping sequence. Numbers of Pratylenchus brachyurus were maintained on triticale and generally increased more on soybean than on cotton. Population densities of Helicotylenchus dihystera wee near or below detection levels in all plots during the first year and increased thereafter in untreated plots in the T-C-T-C and T-S-T-S sequences. Generally, yields of triticale in all cropping sequences declined over the years. Yields of cotton and soybean were not affected by fenamiphos at 6.7 kg a.i./ha. Cotton and soybean were grown successfully with little or no suppression in yields caused by nematodes in conservation tillage following triticale harvested for grain.

AB:   Pin cherry (Prunus pensylvanica L.) develops an early height advantage over associated species. Data from three long-term studies, extending up to 70 years after complete overstory removal, were used to evaluate the effects of pin cherry density on associates. Survival of seedling-origin stems of black cherry (Prunus serotina Ehrh.), red maple (Acer rubrum L.), and sugar maple (Acer saccharum Marsh.) at age 15 decreased as the density of pin cherry >1.5 m tall at age 3 increased. The regression of pin cherry with black cherry was particularly strong (R2 = 0.632). Height of the tallest black cherry and white ash (Fraxinus americana L.) at age 15 also decreased. If the density of pin cherry at age 3 was > 1 stem > 1.5 m tall per 0.0004 ha (high density), the number of black cherry fell below full stocking at age 15. When pin cherry occurred in high density, it lived longer than when it occurred at low density (< 1 stem > 1.5 m tall per 0.0004 ha). High pin cherry density early in stand development delayed the time when shade-intolerant and shade-intermediate species reached a stable proportion of the total basal area. In the long term, pin cherry reduced stand diameter and volume growth, particularly of black cherry.

AB:   While volume growth of individual sawtimber trees is dependent on changes in diameter and merchantable height, value growth is dependent on these along with changes in tree quality, the quality of logs recovered from the tree, and market prices. For sugar maple and other northern hardwood species, quality development is at least as important as biological growth in determining value growth, making development of silvicultural prescriptions and marketing guidelines complex but extremely important for maximizing returns. This paper utilizes projection methods from the literature to develop expected rates of biological and value growth for sugar maple in managed, uneven-aged forests. These rates are presented by 2 in. diameter class and one-half 16 ft log merchantable height classes. Based on the models, the projected rate of biological growth increases with tree diameter and decreases with merchantable height. The rate of value growth generally increases with tree diameter and decreases with merchantable height, but the relationships with tree grade are complex.

AB:   Nematicidcs are used to control a wide variety of nematodes on many crops; unfortunately, oftentimes the control they provide is erratic. This erratic behavior is not always predictable and has been associated with chemical, physical, and biological degradation of nematicides. Their accelerated degradation is an agricultural problem that has been observed in crop monocultures and in other crop production systems where a biodegradable compound is repeatedly applied to the same soil. The problem can occur in field soil and golf course greens; it is not unique to any single nematicide or class of nematicides, but rather to many classes of pesticides. As indicated by the population density of root-knot nematodes (Meloidogyne incognita) in the soil in a 6-year sweet corn-sweet potato-vetch rotation, the efficacy of the nematicide fenamiphos diminished during the third year. Therefore, use of the nematicide applied immediately before planting sweet corn, sweet potato, and vetch should not exceed 3 years. After 3 years, the crop rotation and(or) the nematicide should be changed.

AB:   This manuscript develops an empirical test for identifying the presence of non-price discriminatory trade in the Japanese wheat imports. The test only requires statistical comparison of the mean markups by port of import, by class of wheat, and country of origin. The non-parametric test reveals a trade preference by Japan for Australian Soft White wheat and the Canada Western Red Spring wheat relative to US Hard Red Winter wheat. This apparent trade preference may account for the intensity of the US trade policy to liberalize Japanese wheat import access under the WTO.

AB:   A dose-dependent inhibitory effect of wheat, alfalfa and ginkgo biloba (EGb) extracts on TBARS production was measured. The half-inhibition concentration (IC50) of the tested antioxidants were 2.7+/-0.2, 1.3+/-0.1, and 0.20+/-0.02 mg/ml for wheat, alfalfa and EGb extracts, respectively. Lipid radicals combined with the spin trap POBN resulted in adducts that gave a characteristic EPR spectrum. The IC50 of the tested antioxidants on lipid radical content, were 12.4+/-0.2, 7.7+/-0.3, and 1.20+/-0.06 mg/ml for wheat, alfalfa and EGb extracts, respectively. Rat liver microsomes in the presence of DMPO, NADPH and iron-citrate generate an EPR spectra with characteristics of the DMPO-OH spin adduct. The basic system, without the addition of any scavenger showed an area of 3.5 AU/mg protein. The areas in the presence of 1.5 mg/ml EGb, 4 mg/ml wheat or alfalfa, were of 1.7+/-0.2, 3.4+/-0.3, and 3.6+/-0.2 AU/mg protein, respectively. O2- generation rate by the microsomes exposed to EGb extract was decreased by 40%, as compared to the rate measured in microsomes incubated in the absence of the extract. However, the supplementation of rat liver microsomes with either wheat or alfalfa extracts did not affect microsomal generation of O2-. Iron reduction rate was not affected by the addition of any of the tested extracts. The data presented here showed that EGb extracts were able to limit lipid peroxidation and scavenge lipid radicals in rat liver microsomes more efficiently than alfalfa and wheat bran extracts. Moreover, wheat and alfalfa extracts were not able to inhibit O2- and (.)OH generation by biological membranes, suggesting that their potentiality to be successfully used in human health in the.
       treatment of diseases involving free radical and oxidative damage are not as promising as that for the use of EGb extracts.

AB:   Objective: To describe the health practices and energy and nutrient intakes from diet and supplements of foreign- and US-born Latinas and white non-Latinas in the 3 months before pregnancy. Design: A descriptive study in which data were obtained retrospectively from 2 questionnaires: an interviewer-administered questionnaire on the subject's medical, reproductive, family, occupational, and lifestyle history and a subject-administered (and interviewer-assisted) 100-item food frequency questionnaire. Subjects/setting: A population-based sample of California women (n=462) who gave birth between 1989 and 1991 to single, live-born infants. One third of women were Latinas, of whom 58.1% were foreign born. Statistical analyses: Means, standard deviations, and percentiles were computed for energy and nutrient intakes of the total population and for white non-Latinas; US-born Latinas; and foreign-born Latinas. One-way analysis of variance was used to compare group means. Results: Mean and median energy intake in all ethnic groups exceeded 2,000 kcal/day, although less than half of the population consumed 5 servings of fruit and vegetables per day. For iron, half of the women were below the Recommended Dietary Allowance. In contrast to the dietary intake of white non-Latinas and US-born Latinas, foreign-born Latinas had the lowest contribution of fat to total energy intake and the highest dietary intake of carbohydrate, cholesterol, fiber, grain products, protein foods, folate, vitamin C, iron, and zinc. Conclusions: A woman's ethnicity, as well as whether her place of birth was within or outside of the United States, may be predictors of her dietary and health practices before pregnancy. Vitamin, mineral, and food.
       supplementation and consumption of cold breakfast cereal may be avenues for improving perinatal micronutrient intake.

AB:   Variation in the DNA content attributed to sources such as variation in the amount of heterochromatin and occurrence of supernumerary chromosomes (Bs) in native races of maize cultivated at different altitudes (80-3620 m) is discussed. These populations present intra- and interpopulational variation in the DNA content of the regular complement (A-DNA) and the heterochromatic zones (DAPI bands). The mean number of Bs varied from 0 to 2.62 per plant among these populations, showing a positive correlation with the altitude of cultivation. In contrast, both the A-DNA content and the mean number of DAPI bands per plant were negatively correlated with altitude and the mean number of Bs per plant. These clinal variations in A-DNA content and the mean number of DAPI bands, and the inverse correlation of the mean number of Bs per plant over an altitudinal gradient could have an adaptative significance. Analysis of total DNA content and the number of DAPI bands, in individuals with different doses of Bs, indicates that in populations with high A-DNA content the increase in genome size due to Bs could be masked. This phenomenon is associated with the fact that individuals with Bs have a low number of DAPI bands. These results suggest that there is an optimum nucleotype for each population and that Bs are tolerated so long as this nucleotype is not exceeded.

AB:   Previously, we found a significant negative correlation between DNA C-value and altitude among eight natural populations of Dactylis glomerata L. (Creber et al., New Phytologist 128: 555-561, 1994). We have examined the extent to which similar negative relationships exist in other altitudinal transects, one in southern France and the other in Italy. Using Feulgen microdensitometry, C-values were negatively correlated with altitude both for the French and Italian populations. A combined plot of DNA C-values against altitude for all of the transects (representing C-values for 17 natural populations), exhibited a highly significant negative relationship; there was a 1.3-fold variation in DNA C-value from the largest genome-lowest altitude to the smallest genome-highest altitude natural population. Such a consistent marked altitudinal cline suggests strong nucleotypic selection acting upon these populations with increasing altitude. Preliminary examination of amplified fragment length polymorphisms between populations selected from the upper and lower limits of the French and Italian transects has shown that these populations are genetically distinct. The extent to which this genetic separation is related to altitude or genome size, or both, is discussed.

AB:   Estimates of the size and copy number of the retrotransposons in a 240 kb region flanking the adh1 gene of maize suggest that 33-62% of the maize genome is composed of the high copy-number retrotransposons found in this region. An additional 16% of the maize genome is estimated to be composed of middle and low copy-number retrotransposons. The sorghum genome, which is more than three-fold smaller than the maize genome, does not have any detected copies of the maize retrotransposons in a region orthologous to that of maize adh1. Thus, it appears that retrotransposons have increased the size of the maize genome two- to five-fold since the divergence of maize and sorghum from a common ancestor about 16 million years ago.

AB:   High pressure freezing and freeze substitution (HPF-FS) were used to prepare barley (Hordeum vulgare L. cv Himalaya) aleurone protoplasts for transmission electron microscopy (TEM). We show that HPF-FS is superior to conventional chemical fixation and dehydration techniques for the preservation of cellular fine structure and antigenicity of proteins in barley aleurone protoplasts. HPF-FS extracted fewer proteins from the cytosol and organelles of aleurone protoplasts and maintained the details of cellular structure. The cortical cytoskeleton, made up of microtubules, was observed for the first time by TEM in barley aleurone protoplasts prepared by HPF-FS. Organelles such as protein storage vacuoles retained their proteinaceous contents, and other cellular organelles (including the Golgi apparatus, the nucleus and mitochondria) were also well preserved in protoplasts fixed by HPF-FS. Antibodies to the vacuolar enzyme nuclease I, the tonoplast aquaporin alpha-TIP and the glyoxysomal enzyme malate synthase showed that the antigenicity of organellar enzymes and membrane proteins was preserved in cells prepared by HPF-FS. We conclude that HPF-FS is superior to chemical fixation for the preparation of plant protoplasts for TEM and is the method of choice for the preservation of aleurone protoplasts for structural and immunochemical studies.

AB:   Dof proteins are a family of transcription factors that share a unique DNA-binding domain. Dof proteins were found recently in association with diverse promoters of plant-specific genes, suggesting various roles of Dof proteins in plants. Through binding site selection experiments using randomly synthesized DNA, the recognition sequences of four maize Dof proteins were systematically analyzed. All selected oligonucleotides contained an AAAG sequence, suggesting that this sequence is the recognition core of Dof proteins. In fact, a single mutation in this sequence abolished binding of all four Dof proteins. Furthermore, the preference of each Dof protein for the sequence flanking the core motif was also analyzed using oligonucleotides containing a fixed AAAG and random flanking sequences. Similar, as well as distinct, flanking sequences were observed among the optimal binding sites. Changes in the flanking sequences did affect DNA-binding of Dof proteins.

AB:   Improving estimates of the nutrient content of boles in forest ecosystems requires more information on how the chemistry of wood varies with characteristics of the tree and site. We examined Ca and Mg concentrations in wood at the Hubbard Brook Experimental Forest. Species examined were the dominant tree species of the northern hardwood forest and the spruce-fir forest. The concentrations of Ca and Mg, respectively, in lightwood of these species, mass weighted by elevation, were 661 and 145 microgram/g for sugar maple (Acer saccharum Marsh.), 664 and 140 microgram/g for American beech (Fagus grandifolia Ehrh.), 515 and 93 microgram/g for yellow birch (Betula alleghaniensis Britt.), 525 and 70 microgram/g for red spruce (Picea rubens Sarg.), 555 and 118 microgram/g for balsam fir (Abies balsamea (L.) Mill.), and 393 and 101 microgram/g for white birch (Betula papyrifera Marsh.). There were significant patterns in Ca and Mg concentrations with wood age. The size of the tree was not an important source of variation. Beech showed significantly greater concentrations of both Ca (30%) and Mg (33%) in trees growing in moist sites relative to drier sites; sugar maple and yellow birch were less sensitive to mesotopography. In addition to species differences in lightwood chemistry, Ca and Mg concentrations in wood decreased with increasing elevation, coinciding with a pattern of decreasing Ca and Mg in the forest floor. Differences in Ca and Mg concentration in lightwood accounted for by elevation ranged from 12 to 23% for Ca and 16 to 30% for Mg for the three northern hardwood species. At the ecosystem scale, the magnitude of the elevational effect on lightwood chemistry, weighted by species, amounts to 18% of.
       lightwood Ca in the watershed and 24% of lightwood Mg but only 2% of aboveground biomass Ca and 7% of aboveground Mg.

AB:   Spatial patterns of litterfall and soil nitrogen (N) mineralization were investigated in an old growth hemlock-hardwood forest to test the hypothesis that the lignin/N ratio of litterfall is negatively correlated with soil N availability. Litterfall was measured at 50 small subplots on a 7.2-ha mapped plot in Sylvania Wilderness Area, Michigan, where there is pronounced patchiness of species in the canopy. Nitrogen mineralization and nitrification were measured concurrently at the subplots using buried-bag incubations. Total aboveground litterfall was 3723 kg(.)ha-1 per year with leaf litterfall contributing 69% of the total, and N mineralization was 68.0 kg(.)ha-1 per year. The lignin/N ratios of leaf litter and total litterfall were negatively correlated with soil N mineralization and nitrification at the 50 subplots. Nitrogen mineralization rates, especially percent nitrification, were higher where basswood and sugar maple litterfall dominated and lower where hemlock litterfall was high, demonstrating the importance of litterfall and leaf litter chemistry to soil N pattern on a fine spatial scale. The effect of leaf litter chemistry on soil N may be a positive feedback mechanism that maintains the landscape-scale canopy mosaic at Sylvania.

AB:   Zonation is often seen in environments with a strong physico-chemical gradient, such as salt marshes. It has been hypothesized that plant species are limited in their distribution by abiotic factors towards the more extreme end of the gradient, and by competition towards the more favourable end. Invasion of the native clonal grass genus Elymus in many Wadden Sea marshes may be due to increasing atmospheric nitrogen input into a nitrogen-limited environment. However, at Thmlauer Bay, Germany, Elymus athericus does not occur in lower salt marsh communities that are dominated by a dwarf shrub (Atriplex portulacoides). We therefore hypothesized that at this site the downslope ( = more extreme) distributional boundary of E. athericus is a result of competition with A. portulacoides rather than of physiological limits. A factorial experiment was set up to investigate the effects of removal of each competitor and fertilization. The reciprocal effects of the species on each other were measured in terms of vegetation cover and above-ground biomass. The impact of the tidal regime on plant zonation was investigated by calculating inundation frequencies at the boundary between the two plant populations from water level recordings. Elymus athericus extended its distribution into the lower salt marsh when A.portulacoides was removed. The latter increased in cover but not in biomass after the removal of E. athericus. Neither species showed a response to nitrogen fertilization. The boundary between the two species in the control plots varied considerably in elevation and inundation frequency. The lower distributional boundary of E. athericus can be interpreted as the result of competition with A.
       portulacoides. Improvement of nitrogen availability in concentrations of the same order of magnitude as annual atmospheric input had no detectable effect on plant zonation and growth. Elevation and inundation frequency were not strictly correlated with plant zonation.

AB:   Several hypotheses have been put forward to explain the phenomenon of masting or mast seeding, i.e. the supra-annual, periodic production of a large number of seeds in long-lived plants. Some of these hypotheses deal with the proximate causes of masting (e.g. the climate hypothesis) but others are concerned mostly with ultimate, evolutionary explanations (e.g. the pollination efficiency hypothesis). The seed production of three tree species, Abies balsamea, Acer saccharum and Betula alleghaniensis, was followed over a 7-year period in an old-growth, cold temperate forest of north-eastern North America. The main objectives were to determine the extent of interannual variations in seed production, to investigate the relationship between viable and potential seed crop and crop efficiency, and to explore the effects of climate on seed production. Potential and viable seed production varied significantly among years for all three species. However, the timing of dispersal remained the same regardless of the level of seed production. Seed rain was spatially less heterogeneous in years of high seed production, suggesting that most trees were reproducing in such years. Over the 7-year period, there was a significant concordance among species in their viable seed crop and crop efficiency, but not in their potential seed crop. Crop efficiency was positively correlated to potential seed crop for Abies and Betula, but not for Acer. High seed production was related to warm, dry conditions in the spring of the previous year (i.e. at reproductive bud initiation) but to a moist summer in the year of seed maturation. Masting in these three species thus appears to be controlled by several factors, including climate and.
       pollination efficiency.

AB:   Photoconversion of the plant photoreceptor phytochrome A (phyA) from its inactive Pr form to its biologically active Pfr form initiates its rapid proteolysis. Previous kinetic and biochemical studies implicated a role for the ubiquitin/26S proteasome pathway in this breakdown and suggested that multiple domains within the chromo-protein are involved. To further resolve the essential residues, we constructed a series of mutant PHY genes in vitro and analyzed the Pfr-specific degradation of the resulting photoreceptors expressed in transgenic tobacco. One important site is within the C-terminal half of the polypeptide as its removal stabilizes oat phyA as Pfr. Within this half is a set of conserved lysines that are potentially required for ubiquitin attachment. Substitution of these lysines did not prevent ubiquitination or breakdown of Pfr, suggesting either that they are not the attachment sites or that other lysines can be used in their absence. A small domain just proximal to the C-terminus is essential for the form-dependent breakdown of the holoprotein. Removal of just six amino acids in this domain generated a chromoprotein that was not rapidly degraded as Pfr. Using chimeric photoreceptors generated from potato PHYA and PHYB, we found that the N-terminal half of phyA is also required for Pfr-specific breakdown. Only those chimeras containing the N-terminal sequences from phyA were ubiquitinated and rapidly degraded as Pfr. Taken together, our data demonstrate that, whereas an intact C-terminal domain is essential for phyA degradation, the N-terminal domain is responsible for the selective recognition and ubiquitination of Pfr.

AB:   January 1, 1998 was the effective date for FDA regulations that mandated the fortification in the USA of a wide range of enriched cereal-grain products with folic acid at levels specified in federal regulations. Because data on prefortification levels of folate in such products are limited, we measured folate in 56 enriched foods, including enriched breads and rolls, flours, corn grits and meals, rices, and macaroni and noodle products. Folate was measured by a modification of the Association of Official Analytical Chemists' microbiological method 992.05 using Lactobacillus casei. Foods were composited, suspended in 0.1 M phosphate buffer containing 1% ascorbic acid (pH 7.8), autoclaved and cooled. Chicken pancreas conjugase was added and the suspensions were incubated for 16h at 37 degrees C. Values for folate in enriched products were (micrograms/100g): bread and rolls, 24-40; flours, 19-24; corn grits and meals, 22-32; macaroni and noodle products, 27-42; rice, 19-32. Because the single-enzyme method is usually insufficient to liberate food-bound folates, suspensions of foods were also incubated with alpha-amylase and conjugase followed by treatment with protease to determine the effects of the tri-enzyme digestion on release of folates. For many foods, total folate was 20-30% higher after the tri-enzyme digestion than after incubation with conjugase alone. The modifications of AOAC method 992.05 described here provide a microbiological assay method for the determination of folates in cereal-grain products that may be appropriate for collaborative testing.

AB:   The amounts of browning due to the interaction of lysine and xylose occurring when these reactants were in different liquids have been investigated. The reactants were suspended/solvated in water, corn oil, glycerol, different propylene gylcols and mixtures of these liquids. In water the amount of browning was found to equate to the concentration of the reactants to the third power. In glycerol and polypropylene glycol 76 degrees the amount of browning was higher than that achieved for the same amount of reactants in water. In corn oil and polypropylene glycol 1200 no browning was observed. In all samples the addition of water to another liquid caused the level of browning to be increased, until a maximum was achieved. This maximum may have corresponded to the point where all the reactants were soluble in the matrix. Further addition of water decreased the amount of browning. In all cases the amount of browning seemed to relate to the concentration of the reactants if they were calculated as just occurring in the water portion of the matrix. Values calculated in this way were significantly, but constantly a little lower than the experimental results in all cases except for the corn oil, where the values directly corresponded. The predictability of these values was surprising considering that the matrices gave miscible and phase-separated systems.

AB:   The Representative Soil Sampling Scheme of England and Wales was started in 1969. During the 25 year period 1969-1993 mean soil pH values under arable and ley-arable cropping changed little, but under grassland they fell by 0.3 units. Under arable cropping, mean available phosphorus declined whilst available potassium increased fairly steeply for the first eight years then declined again to near the start value by 1993. No significant changes in soil phosphorus and potassium levels were found under ley-arable cropping, but the percentage of fields under ley-arable rotations declined from 33% to 14%. Under grassland, phosphorus and potassium levels both declined, although potassium levels rose initially before falling. For this report England and Wales were also divided into five regions. Wales and the West Country had the lowest pH values; these regions together with the Northern region were also found to have declining pH values. Phosphorus and potassium concentrations have been falling in the Northern region which stands out as having the lowest current potassium status with 20% of all fields deficient at index 0. Changes in pH and nutrients are discussed for soils sampled following the main arable crops. The largest changes found were the reductions in phosphorus and potassium in soils after potatoes. In 1993 almost one in ten sugarbeet crop soils had an excessive phosphorus level (index 5+) giving an increased risk of water pollution by this element. Under arable cropping the proportion of soils with low (< 1.8%) organic matter declined. Average soil organic matter levels for all crops and grass have remained static during the period. It is concluded that agricultural.
       soils in England and Wales have not contributed to an increase in the greenhouse gas carbon dioxide.

AB:   A practical and simple agro-ecological zonation of Mozambique is presented to facilitate the identification of production conditions and to serve as a basis for agricultural recommendations. The zonation is based on: FAO Major Soil Groupings, altitude and mean annual rainfall. The rationale of the zonation is evaluated by correlating these criteria with other climatic variables and the maize growth cycle. The effectiveness of the zonation was tested with maize yield data from fertilizer trials. The results show that FAO Major Soil Groupings explain a significant part of the total variation in N and organic C contents, Olsen P, exchangeable K, pH and CEC. Altitude relates significantly with temperature, maize growth cycle, radiation and rainfall reliability. Mean annual rainfall relates significantly with rainfall reliability and radiation. Grouping the maize fertilizer trials according to the zonation criteria explained 39% of the variation in unfertilized yields and yield responses to NPK fertilization, and 51% of the variation in fertilized (NPK) yields. The agro-ecological zonation on the basis of soil, altitude and mean annual rainfall proved to be a sound and practical way to identify land areas sufficiently homogeneous to be served by the same fertilizer recommendation.

AB:   Experiments were set up at two sites to measure nitrogen (N) leaching loss from applications of separated pig/cattle slurry and cattle farmyard manure (FYM), during winters 1990/91-1993/94 (site A) and from broiler litter and FYM, during winters 1990/91-1992/93 (site B). The manures were applied at a target rate of 200 kg ha-1 total N during the autumn and winter to overwinter fallow or top dressed onto winter rye. The total N in leachate was calculated from leachate N concentrations, in samples collected using ceramic cups buried at 90cm and an estimate of drainage volume. Nitrogen losses were greatest following manure applications in September, October and November but losses following applications in December or January were not significantly elevated above those from untreated controls. Losses were consistently lower from FYM than from broiler litter or separated slurry. The presence of a cover crop (winter rye) significantly reduced overall N leaching compared with the fallow but only reduced the manure N leaching losses at one site during one winter when a high proportion of drainage occurred late. The incorporation of a nitrification inhibitor (DCD) with manures applied in October did not significantly reduce the manure N leaching.

AB:   A (glucurono)arabinoxylan extract obtained from water-unextractable cell wall material of industrial wheat bran was fractionated by means of anion-exchange chromatography and graded ethanol precipitation. Methylation analysis and enzymic degradability of various fractions were used to elucidate their structures. Approximately one third of the extracted (glucurono)arabinoxylan was very lowly substituted (Ara/Xyl approximately equal to 0(.)2). Substitution occurred predominantly by arabinose at the O-3 position of xylose residues. Enzymatic degradation showed a random distribution of the substituents, which are probably interrupted by stretches of 6 or more contiguous unsubstituted xylose residues. More than half the extracted (glucurono)arabinoxylan was highly substituted (Ara/Xyl greater than or equal to 1). The complexity of the structure was shown by poor enzymic degradability and the presence of considerable amounts of branched arabinose and terminal xylose. Substitution of xylose occurred not only through O-3 mono, O-2 and O-3 disubstitution by terminal arabinose and O-2 monosubstitution by (4-O-methyl) glucuronic acid, but also through dimeric arabinose, xylose and possibly galactose containing branches as well as through 2,3-linked arabinose. The remainder of the extracted (glucurono)arabinoxylan (15%) was either intermediately substituted (Ara/Xyl approximately equal to 0(.)5) or very highly substituted (Ara-Xyl approximately equal to 1(.)2) and associated with protein and lignin.

AB:   Short term incubations (4 d) were conducted to assess the effect of a wetting/drying cycle on atrazine sorption, as well as biodegradation, as a function of various atrazine concentrations (ca. 5, 10, and 25 microgram g-1 soil) and levels of added crop residues (0, 5, and 10% cornstalks by weight), using a technique that allowed independent analysis of soluble and sorbed atrazine. Soil solution atrazine concentrations decreased, and KdS increased with increasing crop residues. The sorptive capacity of cornstalks for atrazine was estimated to be 860 microgram g-1 vs 28 microgram g-1 for unamended soil. Drying and rewetting resulted in lower soil solution concentrations and decreased extraction efficiencies (13 to 22%) for sorbed atrazine; the effect was most pronounced with added cornstalks. High recoveries of 14C from soils (combustion data) indicated that atrazine was not lost to volatilization. Rapid rates of biodegradation were observed in cornstalk-amended soils shortly after rewetting; degradation was not observed in unamended soil. A longer incubation (6 wk) was conducted with ca. 10 microgram g-1 atrazine and 5% cornstalks to assess metabolites and kinetics of biodegradation. Atrazine disappearance was observed after ca. 2 wk with concomitant production of deethyl- and deisopropyl-atrazine at a ratio of ca. 2:1. Dealkylated-atrazine accumulated after ca. 3 wk; there was no evidence for hydroxy-atrazine production. These data suggest that biodegradation may play an important role in atrazine losses in the field despite wetting/drying cycles. In addition, there may be apparent losses of atrazine due to decreased extraction efficiencies as a consequence of wetting/drying cycles.

AB:   Studies were conducted from 1990 through 1994 near Tifton, GA, on the population dynamics of yellow nutsedge and certain annual weeds in peanut-corn and peanut-cotton rotations. Converse rotation sequences were included to eliminate year effects. Continuous fallow plots (noncrop) were included for comparison. Within each crop, including fallow, were 3 levels of weed management: low, moderate, and intensive. Weed densities and numbers of yellow nutsedge tubers were not affected by crop rotations, but they were affected by individual crops and weed management systems in each crop. Fallow plots, including those with intensive fallow weed management using tillage and nonselective herbicides, consistently contained more yellow nutsedge plants and tubers than other plots. Moderate and intensive weed control systems in peanut and cotton reduced yellow nutsedge densities and tubers, but only peanut yields were increased by intensive weed management. Weed management systems did not affect yellow nutsedge densities in corn, although yields were increased by moderate and intensive systems due to improved control of other weeds. Our results suggest that uninterrupted plantings of peanut, corn, or cotton with moderate levels of weed management are generally sufficient to suppress yellow nutsedge and allow for optimum crop yield. If fields are fallow, yellow nutsedge population densities and tubers will increase exponentially, even with intensive fallow weed management.

AB:   A bioeconomic model was tested as a decision aid for weed control in soybean at Rosemount, MN, from 1991 to 1994. The model makes recommendations for preplant incorporated and preemergence control tactics based on the weed seed content of the soil and postemergence decisions based on weed seedling densities. Weed control, soybean yield, herbicide use, and economic return with model-generated treatments were compared to standard herbicide and mechanical control systems. Effects of these treatments on weed populations and corn yield the following year were also determined. In most cases, the model-generated treatments controlled weeds as well as a standard herbicide treatment. Averaged over the 3 yr, the quantity of herbicide active ingredient applied was decreased by 47% with the seedbank model and 93% with the seedling model compared with a standard soil-applied herbicide treatment. However, the frequency of herbicide application was not reduced. Soybean yields reflected differences in weed control and crop injury. Net economic return to weed control was increased 50% of the time using model-recommended treatments compared with a standard herbicide treatment. Weed control treatments the previous year affected weed density in the following corn crop but had little effect on weed control or corn yield. The bioeconomic model was responsive to differing weed populations, maintained weed control and soybean yield and often increased economic returns under the weed species and densities in this research.

AB:   Research was conducted from 1993 through 1995 to evaluate barnyardgrass control, rice yield, and estimated economic return with POST applications of propanil or propanil + molinate applied alone or with quinclorac. Herbicides were applied under a variety of water management practices and environmental conditions at rates ranging from 1.1 to 3.4, 1.7 to 5.6, and 0.17 to 0.40 kg ai ha-1 for propanil, propanil + molinate, and quinclorac, respectively. Reduced-rate combinations of propanil or propanil + molinate with reduced rates of quinclorac controlled small, actively growing barnyardgrass and provided yields and estimated economic returns similar to combinations of these herbicides at higher rates when irrigated. When herbicides were applied to larger barnyardgrass, propanil + molinate at 5.6 kg ha-1 was more effective than propanil at 3.4 kg ha-1 or quinclorac at 0.40 kg ha-1 applied alone. Propanil + molinate applied with quinclorac at 0.28 or 0.40 kg ha-1 controlled barnyardgrass more effectively and provided higher yields and greater estimated economic returns than propanil at 3.4 kg ha-1, propanil + molinate at 5.6 kg ha-1, quinclorac at 0.17, 0.28, or 0.40 kg ha-1, or combinations of propanil and quinclorac.

AB:   Efficacy of an indigenous fungus, Exserohilum monoceras, for the control of 3 Echinochloa species was evaluated and compared under both regulated greenhouse and screenhouse (field plots netted with 2 layers of metal mesh screening to exclude vertebrate pests) conditions. Under greenhouse conditions, an inoculum dose of 2.5 X 10(7) conidia m-2 killed all seedlings of both barnyardgrass and E. glabrescens, whereas an inoculum dose of 5.0 X 10(7) conidia m-2 was required to obtain 100% mortality of junglerice seedlings. The 1.5-leaf stage of all 3 Echinochloa species was the most susceptible. Increasing inoculum density increased weed control efficacy on younger or older Echinochloa seedlings. The highest level of control was observed for E. glabrescens, less for barnyardgrass, and least for junglerice. Under screenhouse conditions, Exserohilum monoceras caused more than 90% mortality of Echinochloa species when the inoculum was formulated as an oil emulsion or when applied as a dry powder.

AB:   Giant foxtail, woolly cupgrass, and wild-proso millet infest millions of hectares of land devoted to corn production in the midwestern U.S. Control of these species and effects on corn grain yield were evaluated at various timings using POST applications of nicosulfuron vs. applications of various PRE herbicides at 17 locations across the midwestern U.S. in 1992 and 1993. Nicosulfuron applied to 5 to 10 cm giant foxtail and woolly cupgrass provided greater control than that observed with selected PRE herbicides. Giant foxtail control with nicosulfuron averaged 88%, and control of woolly cupgrass averaged 77% across all sites. Nicosulfuron, applied to 5 to 10 cm wild-proso millet, provided a level of control similar to that of selected PRE herbicides. Corn grain yield was greater when giant foxtail was controlled POST with nicosulfuron vs. PRE control with selected soil-applied herbicides. Corn grain yields were similar when nicosulfuron was applied POST to 5 to 10 cm woolly cupgrass or wild-proso millet vs. PRE control of these grass weeds. Across a broad range of geographical locations, nicosulfuron, applied POST to 5 to 10 cm tall grass, provided greater or similar levels of weed control vs. the selected PRE herbicides, with no deleterious effect on grain yield.

AB:   Resistance to fluazifop-P and quizalofop-P, (aryloxyphenoxypropionates) and sethoxydim (cyclohexanedione) was identified in 2 populations of johnsongrass in both field and greenhouse studies. The cropping history (1983-1991) of the sites indicated 1 or more annual applications of a graminicide (primarily fluazifop-P) since the early 1980s. Under field conditions, control of resistant seedling and rhizome johnsongrass (R91F) with fluazifop-P, quizalofop-P, fenoxaprop-ethyl, and sethoxydim was less than 35%. Clethodim provided up to 80% control of R91F Under greenhouse conditions, ratios (R/S) of the I50 values (amount of herbicide required to inhibit plant growth by 50%) of resistant (2 sites: R91F and R91S) to susceptible (S91H) seedling (20-30-cm height) plants were > 388 (fluazifop-P), > 15 (quizalofop-P), and from 2.3 (R91S) to 3.4 (R91F) (both sethoxydim). For rhizome (30-45 cm height) plants, the R/S ratios were > 388 (fluazifop-P), > 16 (quizalofop-P), and 2.8 (R91S) to 8.5 (R91F) (both sethoxydim). Labeled rates (in kg ai ha-1) of fluazifop-P (0.10 and 0.21), quizalofop-P (0.039 and 0.08), and sethoxydim (0.21 and 0.21) were applied on seedling and rhizome plants, respectively, and resulted in little or no control of resistant johnsongrass. Greenhouse studies indicated registered rates of clethodim (0.10 and 0.14 kg ai ha-1 for seedling and rhizome plants, respectively) effectively controlled the resistant populations, but tolerance was measured for both seedling and rhizome plants at sublethal doses (down to 0.007 and 0.009 kg ai ha-1, respectively), with I50 ratios ranging from 1.5 (R91S) to 2.1 (R91F) for seedling plants and 4.5 (R91S) to 4.8 (R91F) for rhizome plants. Control of resistant.
       seedling and rhizome johnsongrass under field conditions was adequate with glyphosate at 0.84, glufosinate at 0.84, and sulfosate at 0.84 kg ai ha-1, indicating no cross-resistance.

AB:   Yield loss of hard red spring wheat due to competition from common milkweed was measured in grower fields in Minnesota. Wheat yield loss was measured using the area of influence and additive competitive methods. Simple linear regression of wheat yield and percentage wheat yield loss against distance from a common milkweed shoot gave r2 values of 0.013 and 0.015, respectively, indicating limited value of the area of influence model for common milkweed in spring wheat. In an additive competition model, wheat yield was reduced 47% at the highest density of 12 common milkweed shoots m-2. Coefficients of determination for percentage yield loss regressed against common milkweed shoot density were 0.548, 0.547, and 0.529 for simple linear, nonlinear rectangular hyperbolic, and linear square root function models, respectively. Regression of percentage yield loss against common milkweed biomass resulted in r2 values of 0.566, 0.645, and 0.658 for simple linear, nonlinear rectangular hyperbolic, and linear square root function models, respectively. Restrictions of common milkweed density due to factors other than competition limited yield loss response to the simple linear phase of both the nonlinear rectangular hyperbolic and the linear square root function models previously described.

AB:   We studied the effect of no-till, chisel, and moldboard plow and the presence or absence of corn on soil temperature, moisture and, subsequently, the emergence phenology and density of pigweed seedlings at 2 sites from 1993 to 1995 inclusively. Tillage significantly affected the phenology of pigweed seedling emergence only during a June drought at one site in 1994. Soil temperature and moisture, measured at 2.5-cm depths, also were unaffected by tillage. Weed phenology is usually earlier in no-till because more seeds are located closer to the surface (< 5 cm deep) in no-till, thereby reducing the delay in penetrating through the soil, and because soil temperatures and moisture are nearer the germination and emergence optima. However, pigweed seedlings are already physiologically restricted to germination depths of less than 2.5 cm regardless of tillage; therefore, this prior constraint eliminated any potential differences in emergence phenologies caused by tillage. The presence or absence of corn also did not affect soil temperatures, soil moisture, or pigweed seedling emergence phenologies. Pigweed seedling density was significantly higher in no-till; this may have been caused by increased numbers of seeds near the soil surface in no-till. The presence or absence of corn did not affect pigweed seedling density; the lack of a significant effect probably reflects high variances in density. Although necessary for most weed species, tillage may be a less important factor to consider in predicting pigweed population dynamics and subsequent management recommendations.

AB:   Intensive surveys were conducted in 2 fields in eastern Nebraska to determine the spatial stability of common sunflower, velvetleaf, green and yellow foxtail, and hemp dogbane over 4 yr (1992 to 1995). The 1st field was planted to soybean in 1992 and corn in 1993, 1994, and 1995. The 2nd field was planted to corn in 1992 and 1994 and soybean in 1993 and 1995. Weed density was sampled prior to post-emergence herbicide application at approximately 800 locations per year in each field on a regular 7 m grid. The same locations were sampled every year. Weed density at locations between the sample sites was determined by linear triangulation interpolation. Weed seedling distribution was significantly aggregated, with large weed-free areas in both fields. Common sunflower, velvetleaf, and hemp dogbane patches were very persistent in diameter in the east-west and north-south directions and in location and area over 4 yr in the 1st field. Foxtail distribution and density continuously increased in each of the 4 yr in the first field and decreased in the 2nd field. A geographic information system was used to overlay maps from each year for a species. This showed that 36% of the sampled area was continuously free of common sunflower, 62.5% was free of hemp dogbane, and 11.5% was free of velvetleaf in the 1st field, but only 1% was free of velvetleaf in the 2nd field. The persistence of broadleaf weed patches suggests that weed seedling distributions mapped in one year are good predictors of future seedling distributions. Improved and more efficient sampling methods are needed.

AB:   The impact of seed production by subthreshold weed populations on future weed problems has impeded the adoption of integrated pest-management principles for weed management. Studies were conducted in fields with no velvetleaf history to determine how seedbanks and seedling populations change following seed production 1 yr or 5 consecutive yr in plow-disk and no-tillage corn. Cumulative seed production by 0.19 velvetleaf plants m-2 increased in a linear fashion from 1989 to 1994, with annual additions averaging from 330 seeds m-2 for velvetleaf in corn to 2,500 seeds m-2 for velvetleaf without competition from corn. Five-year cumulative seed production was 1,480 seeds m-2 in plow-disk and 1,810 seeds m-2 in no-till corn. In no-till corn, 42 velvetleaf seedlings m-2 emerged the 1st year after the 1989 seed rain, but only 35 seedlings m-2 emerged over the next 4 yr. In plow-disk plots, annual emergence averaged 12 seedlings m-2. Five years after the 1989 seed rain, the proportion of seeds lost to emergence was about 20% in both tillage treatments. Where velvetleaf seeds were allowed to return to the soil every year, cumulative seedling emergence was lower in plow-disk than in no-till corn, with total emergence of 70 and 360 seedlings m-2, respectively, after 5 yr. Seedbank numbers ranged from 10 seeds m-2 5 yr after a single seed rain (290 seeds m-2) by velvetleaf in plow-disk corn to 1,020 seeds m-2 following 5 consecutive yr of seed rain where 12,580 seeds m-2 were returned without corn competition in no-till. Seedbank samples in the fall of the 5th year had 69 to 98% fewer seeds than were accounted for by cumulative seed rain and seedling emergence, with greater apparent seed losses.
       in plow-disk corn than in no-till corn. Over 90% velvetleaf control would be required annually to maintain subthreshold populations for 5 yr following a single seed rain. By comparison, over 95% control would he required annually to maintain subthreshold populations where velvetleaf seed return is permitted each year.

AB:   The establishment of common milkweed in corn, soybean, and wheat and rotations of corn-soybean and soybean-wheat was determined in field studies at Rosemount and Morris, MN. Common milkweed seedling density 115 d after initial seedling emergence was 500, 15,000, and 31,300 seedlings ha-1 in corn, soybean, and wheat, respectively, in 1990; 500, 7,300, and 15,600 in 1991 at Rosemount and 2,900, 26,500, and 37,000 in 1990; and 2,200, 6,700, and 8,100 in 1991 at Morris in the year of seedling establishment. Common milkweed seedling defoliation by monarch butterfly larva was 1, 31, and 0% at Rosemount and 20, 78, and 0% at Morris for corn, soybean, and wheat, respectively. In the 2nd and 3rd rotational years, corn-soybean rotations had fewer shoots ha-1 115 d after shoot emergence than soybean-wheat rotations. Seedling densities 115 d after initial seedling emergence were greater in corn-soybean rotations where soybean rather than corn was the rotational crop and in soybean-wheat rotations where wheat rather than soybean was the rotational crop immediately following common milkweed seeding. Conventional tillage treatments had lower common milkweed shoot density than conservation tillage in all years of all rotations except in the initial count, when soybean was the first rotational crop in which shoot density was greater in conventional than in conservation tillage treatments. Cyanazine, imazethapyr, or bromoxynil applications in corn, soybean, or wheat rotational crops, respectively, reduced common milkweed shoot density.

AB:   Greenhouse and laboratory studies were conducted to determine the physiological basis for selectivity of nicosulfuron and primisulfuron in 5 plant species. Differential sensitivity of the species was quantified by determining GR50 values (herbicide rate required to reduce plant growth 50%) for each species/herbicide combination. GR50 data indicated the following levels of sensitivity: corn--tolerant to both herbicides; seedling johnsongrass--sensitive to both herbicides; barnyardgrass--sensitive to nicosulfuron and tolerant to primisulfuron; giant foxtail--sensitive to nicosulfuron and tolerant to primisulfuron; and eastern black nightshade--tolerant to nicosulfuron and sensitive to primisulfuron. Studies using 14C-radiolabeled herbicides were conducted to determine whether differential herbicide absorption, translocation, or metabolism contributed to whole plant responses. Nicosulfuron and primisulfuron selectivity in corn, johnsongrass, barnyardgrass, and giant foxtail was primarily due to differential herbicide metabolism rate. Tolerant species metabolized the herbicide more rapidly and extensively than sensitive species. Differential herbicide absorption, translocation, or metabolism did not explain differential sensitivity of eastern black nightshade to the herbicides. Further studies indicated that the tolerance of eastern black nightshade to nicosulfuron and its sensitivity to primisulfuron was directly related to lower sensitivity of the acetolactate synthase (ALS) to nicosulfuron than to primisulfuron. Eastern black nightshade translocated very little (3%) of the nicosulfuron applied. The ALS sensitivity of johnsongrass and eastern black nightshade was similar.
       in the presence of nicosulfuron. A combination of a higher ALS level and less herbicide translocation contributes to tolerance of eastern black nightshade and to sensitivity of johnsongrass to nicosulfuron.

AB:   Controlled environment experiments were completed to determine the effect of temperature on giant foxtail and fall panicum germination, emergence, and growth. Giant foxtail seed germination decreased when exposed to a constant 30 C compared to 20 C. Germination also decreased in the alternating 20/30 C temperature regime when the hours of exposure to 30 C as compared to 20 C increased. Fall panicum required alternating temperatures of 14 C (9 h)/28 C (15 h) to germinate. Giant foxtail seed germination exceeded 60% 4 d after exposure to an alternating temperature of 7 C (9.4 h)/20 C (14.6 h). Conversely, fall panicum seed did not germinate at the 7 C (9.4 h)/20 C (14.6 h) temperature regime and required a minimum of 7 d exposure to alternating temperatures of 13 C (8.7 h)/26 C (15.3 h) for 88% of the seed to germinate. The greatest emergence of giant foxtail and fall panicum was from 1 cm and 1 to 2.5 cm, respectively. Less than 5% of the giant foxtail and fall panicum seed emerged from 7.5 cm. The growth of giant foxtail seedlings was five times greater than that of fall panicum at each temperature regime tested. Incorporation of this information into bioeconomic models could result in accurate predictions of weed germination for effective weed management strategies.

AB:   In order to determine the gene structure and promoter region of vacuolar H+ -translocating inorganic pyrophosphatase (V-PPase), we isolated the genomic clones using a rice BAC library and probes derived from rice V-PPase cDNA (OVP1). The entire OVP1 gene is approx. 5.4 kb in length, and seven introns interrupt the coding sequence of OVP1. The first intron is extremely large (1869 bp), while the other introns are between 82 and 170 bp. A transcription initiation site, identified by a primer extension analysis, indicated the first exon to be 366 bp. A 1.1 kb fragment containing the 5'-flanking region of the first exon with the GUS reporter gene showed specific promoter activity in rice cells. These data show that the OVP1 gene is composed of eight exons and seven introns, and regulatory elements are present within 1.1 kb upstream from the first exon.

AB:   A genomic DNA fragment from Triticum tauschii, the donor of the wheat D genome, contains a starch branching enzyme-I (SBE-I) gene spread over 6.5 kb. This gene (designated wSBE I-D4) encodes an amino acid sequence identical to that determined for the N-terminus of SBE-I from the hexaploid wheat (T. aestivum) endosperm. Cognate cDNA sequences for wSBE I-D4 were isolated from hexaploid wheat by hybridisation screening from an endosperm library and also by PCR. A contiguous sequence (D4 cDNA) was assembled from the sequence of five overlapping partial cDNAs which spanned wSBE I-D4. D4 cDNA encodes a mature polypeptide of 87 kDa that shows 90% identity to SBE-I amino acid sequences from rice and maize and contains all the residues considered essential for activity. D4 mRNA has been detected only in the endosperm and is at a maximum concentration mid-way through grain development. The wSBE I-D4 gene consists of 14 exons, similar to the structure for the equivalent gene in rice; the rice gene has a strikingly longer intron 2. The 3' end of wSBE I-D4 was used to show that the gene is located on group 7 chromosomes. The sequence upstream of wSBE I-D4 was analysed with respect to conserved motifs.

AB:   Three genes encoding the low-molecular-weight glutenin subunits (LMW-GSs). LMWG-E2 and LMWG-E4, from A-genome diploid wheat species, and LMW-16/10 from a D-genome diploid wheat were expressed in bacteria. The respective proteins were produced on a relatively large scale and compared with respect to their effects on flour-processing properties such as dough mixing, extensibility and maximum resistance; these are important features in the end-use of wheat for producing food products. The LMWG-E2 and LMWG-E4 proteins caused significant increases in peak resistance and mixing time, compared to the control, when incorporated into dough preparations. The LMWG-16/10 protein was qualitatively less effective in producing these changes. All three proteins also conferred varying degrees of decrease in dough breakdown. LMWG-E2 and LMWG-E4 caused significant increases in dough extensibility, and decreases in maximum resistance, relative to the control, LMW-16/10 did not show a significant effect on extensibility but showed a significant decrease in maximum resistance. The refinement of relating specific features of the structure of the LMW-GS genes to the functional properties of their respective proteins is discussed.

AB:   The isolation and characterisation by DNA sequencing of two different low molecular weight glutenin subunit (LMW-GS) genes from a genomic library derived from Triticum tauschii is described. These genes are similar (more than 90% similarity) but not identical to previously published LMW-GS gene sequences from cultivated wheats. A comparison of nucleotide sequence of the coding regions revealed the presence of insertions and deletions preferentially located in the region encoding the domains in the LMW-GS proteins rich in proline and glutamine and the middle part of the C-domain. The signal sequences, the amino-terminus and the remaining parts of the C-domain were conserved between all the LMW-GSs compared. The differences detected between the deduced amino-acid sequences in these three regions are only due to single nucleotide substitutions. The most important characteristic of all compared LMW-GS genes is the conservation of eight cysteine residues that could be involved in potential secondary or tertiary structure and disulphide-bond interactions. Comparisons between the 5 and 3' non-coding sequences of one of the isolated clones (LMW-16/10) with those of different prolamin genes from wheat, barley and rye led to the distinction of five different gene families, and confirmed the evolutionary relationships determined previously for these genes mainly on the basis of the coding region. In particular, the LMW-GS sequences are more closely related to the B-hordein sequences than to any other prolamin genes from wheat, barley and rye, Formal proof that the isolated genes coded for LMW-GSs, as defined by gel electrophoresis, was obtained by moving one of these genes (LMW-16/10) into a bacterial.
       expression vector based on bacteriophage T7 RNA polymerase. The resulting plasmid directed the synthesis of large amounts of the mature form of the subunit in Escherichia coli. This protein exhibited solubility characteristics identical to those of the LMW-GSs and cross-reacted with antibodies reactive with these proteins.

AB:   Three accessions of T. boeoticum were selected for the cloning and sequencing of novel low-molecular-weight glutenin subunit (LMW-GS) genes, based on the results of SDS-PAGE and PCR analyses of the LMW-GS diversity in A-genome wheat (Lee et al. 1998 a). A comparison of the nucleotide and deduced amino-acid sequences of three cloned genes, LMWG-E2, LMWG-E4 and LMWG-AQ1, both to each other and to other known LMW-GS genes was carried out. The N-terminal domains showed one variable position; GAG (coding for a glutamic acid) for the E-type, and GAT (coding for an aspartic acid) for the Q-type. The comparisons of the LMW-GSs in the literature and this paper define three different types of N-terminal sequences; METSCIPGLERPW and MDTSCIPGLERPW from the durum and A-genome wheats, and METRCIPGLERPW from the hexaploid and D-genome wheats. The repetitive domains were AC-rich at the nucleotide level and coded for a large number of glutamine residues; this region showed 16 variable positions changing 12 amino-acid residues, three triple nucleotide deletions/additions, a large deletion of 18 nucleotides in LMWG-E4 and a deletion of 12 nucleotides in LMWG-E2. In the C-terminal domains 26 variable positions were found and 12 of these mutations changed amino-acid residues; no deletions/additions were present in this region. It was shown that the LMWG-E2 and LMWG-E4 genes could be expressed in bacteria and this allowed the respective protein products to be related back to the proteins defined as LMW-GSs in vivo.

AB:   A Tris-Tricine gel-electrophoresis system (Schaegger and von Jagow 1987) combined with a gradient gel has been employed to provide an improved resolution of the B and C low-molecular-weight glutenin subunits (LMW-GSs) found in the endosperm of wheat grain. The gel system was used to document the variation in the gluten subunit proteins present in A-genome diploid wheats. The majority of LMW-GSs found in the A-genome diploid wheats were not present in normal bread wheats; the data suggest that they represent a rich source of new variation for the LMW-GSs which are considered to be very important in modulating wheat flour-processing properties. The analysis of variation in the nature of the LMW-GS genes, using PCR, demonstrated that the subclass of C-subunits assayed by primers from a previously published sequence did not show as much variation as the proteins. However, the data collected suggest that sufficient variation may exist in the LMW-GS genes of A-genome diploid wheats to use them as a source of genes for altering the flour-processing properties of hexaploid wheat.

AB:   Fusarium head blight (FHB or scab) caused by Fusarium spp. is a widespread disease of cereals causing yield and quality losses and contaminating cereal products with mycotoxins. The breeding of resistant varieties is the method of choice for controlling the disease. Unfortunately, the genetic basis of scab resistance is still poorly understood. We present the results of a back-cross reciprocal monosomic analysis of FHB resistance using the highly resistant Hungarian winter wheat line 'U-136.1' and the highly susceptible cultivar 'Hobbit-sib'. Resistance testing was performed in a field trial artificially inoculated with a Fusarium culmorum conidial suspension. Five hemizygous families containing 'U-136.1' chromosomes 6B, 5A, 6D, 1B, and 4B had a visually reduced spread of infection compared to lines having the 'Hobbit-sib chromosome. Chromosome 2B from 'U-136.1' had an increased spread of infection. The critical chromosomes controlling seed weight were 6D, 3B, 5A, and 6B while those controlling deoxynivalenol (DON) content were homoeologous groups 2 and 6, although the latter effects were not significant due to a high coefficient of variation. Results from this and other studies show that chromosomes 6D, 6B, 5A, 4D, and 7A have frequently been associated with scab resistance in a number of wheat cultivars. Research groups now attempting to map scab resistance in wheat using markers should pay special attention to the above-mentioned chromosomes.

AB:   Commercial maize (Zea mays L.) in the USA has a restricted genetic base as newer hybrids are largely produced from crosses among elite inbred lines representing a small sample predominantly about 6- to 8-base inbreds) of the Stiff stalk and Lancaster genetic backgrounds. Thus, expansion of genetic diversity in maize has been a continuous challenge to breeders. Tropical germplasm has been viewed as a useable source of diversity, although the integration of tropical germplasm into existing inbred line and hybrid development is laborious. The present study is an evaluation of the potential of tropical germplasm for temperate maize improvement. All possible single-, three-way-, and double-cross hybrids among three largely temperate and three temperate-adapted, all-tropical inbred lines were evaluated in yield-trial tests. Single-cross hybrids containing as much as 50-60% tropical germplasm produced 8.0 t ha-1 of grain yield, equivalent to the mean yield of the commercial check hybrids. On the other hand, three-way and double-cross hybrids with the highest mean yield contained lower amounts of tropical germplasm, 10-19% and 34-44%, respectively. Overall, hybrids containing 10-60% tropical germplasm yielded within the range of the commercial hybrid checks. Hybrids with more than 60% tropical germplasm had significantly lower yields, and 100% tropical hybrids yielded the least among all hybrids evaluated. The results indicate that inbred lines containing tropical germplasm are not only a useful source to expand the genetic diversity of commercial maize hybrids, but they, also are competitive in crosses with temperate materials, producing high-yielding hybrids. These experimental hybrids.
       exhibited good standability (comparable to the commercial check hybrids) but contained 1-2% higher grain moisture, leading to delayed maturity. Recurrent selection procedures are being conducted on derivatives of these materials to extract lines with superior yield, good standability, and reduced grain moisture which can be used for commercial exploitation.

AB:   beta-Amylase deficiency in various cultivars of rice was examined at the molecular level. Using an antibody against beta-amylase purified from germinating seeds of rice, we were able to demonstrate the expression and organization of the beta-amylase gene in normal and deficient cultivars. Although beta-amylase is a starch-hydrolyzing enzyme, as is beta-amylase, the beta-amylase protein/gene is expressed differently from the beta-amylase protein/gene; i.e. 1) beta-amylase is synthesized only in aleurone cells, (2) the enzyme production in the embryo-less half-seeds is not under hormonal control. We identified some cultivars of rice that are deficient for beta-amylase activity. We present new evidence that synthesis is blocked at the level of mRNA synthesis in the deficient cultivars. The usefulness of beta-amylase as a crop trait is also discussed.

H. vulgare ssp. spontaneum (2n = 2x = 14; I-genome) had a similar composition of 5S and 18S-25S rDNA to cultivated barley (H. vulgare ssp. vulgare, I-genome), with two major 18S-25S rDNA sites and minor sites on four of the other five chromosomes; three chromosomes had 5S rDNA sites. The closely related H. bulbosuin (2x; also I-genome) showed only one pair of 5S rDNA sites and one pair of 18S-25S rDNA sites on different chromosomes. Four wild diploid species, H. marinum (X-genome), H. glaucum and H. murinum (Y-genomes) and H. chilense (H-genome), differed in the number (2-3 pairs), location, and relative order of 5S and the one or two major 18S-25S rDNA sites, but no minor 1S-25S rDNA sites were observed. H. murinum 4 had three chromosome pairs carrying 5S rDNA, while the diploid had only a single pair. Two other tetraploid species, H. brachyantherum 4x and H. brevisubulatum 4x (both considered to have H-type genomes), had minor 18S-25S rDNA sites, as well as the major sites. Unusual double 5S rDNA sites -- two sites on one chromosome arm separated by a short distance -- were found in the American H-genome species. H. clilense and H. brachyantherum 4x. The results indicate that the species H. brachyantherum 4x and H. brevisubulatum 4x have a complex evolutionary history, probably involving the multiplication of minor rDNA sites (as in H. vulgare sensu lato), or the incorporation of both I and H types of genome. The rDNA markers are useful for an.

AB:   Resistant starch (RS) was determined in patties (5.1 cm diameter, 1.27 cm high) prepared by mixing starch (corn, rice, wheat, or potato) in distilled water and immersion fried in canola oil (at 170 +/- 3C). The RS content (expressed as % of total starch) in corn starch increased from 4.25 to 5.43% (+/- 0.11) in the core region of a patty, whereas in the outer crust region the RS level was constant throughout the frying process. Similar trend was observed in potato, rice, and wheat starch patties. Upon varying the amylose content in the corn starch from 21 to 70%, the initial RS content (prior to frying) increased from 3.47 to 22. 74 (+/- 0. 11%), following a linear relationship. Maximum force (MF) to puncture the crust of each starch patty was determined for frying duration of 3 to 15 min. Patties exhibiting higher RS content prior to frying, developed crusts with higher MF to puncture the crust, exhibiting a linear relationship between those two variables.

AB:   The ultraviolet (UV), visible and near-infrared (NIR) absorption changes in corn oil were measured awing processes simulating deep fat frying. Corn oil, maintained at 185C, was exposed to various treatments with nitrogen, air, water injection, air with water injection, and steam. Autoxidation due to a combination of air and high temperature in the simulated frying trials caused visible absorption changes between 400 and 580 nm as the oil deteriorated similar to those observed in potato frying experiments. These absorption changes were found to be associated with changes in an ultraviolet absorption band with a maximum near 270 nm. Second-derivative calibration equations developed at various visible and NIR absorption wavelengths successfully predicted the percentage of total polar materials (%TPM) which accumulated in the corn oil during simulated trials of autoxidation (P values from 0.93 to 0.98). Using spectral data from repetitive potato frying experiments, the predicted %TPM calculated with these equations correlated well with kinematic viscosity measurements (R values from 086 to 0.97).

AB:   Chemical analysis of apple pomace revealed that it contains 29.4% neutral detergent fiber and 13.0% pectin. Pomace-flour blends were prepared by incorporating 2, 5, 8 and 11% pomace in wheat flour. Blends were evaluated for their bread making quality. Water absorption increased with the increase of pomace in the blends. Neutralizing the acidity of pomace blended dough did not change the water absorption significantly. As the percentage of pomace in blends increased from 0 to 11, a reduction of 42.8% in loaf volume was observed but neutralization of pomace acidity in dough resulted in only 26.6% reduction in volume under similar conditions. On the other hand loaf weight of the breads, prepared from blends with 11% pomace under unneutralized and neutralized conditions, increased by 7.0 and 3.1%, respectively. With increase of pomace percentage in blends up to 11, the bread firmness increased from 3N in control to 12 and 10N respectively, in unneutralized and neutralized pomace blended dough. Blending of pomace (0-11%) increased baking time from 20 min for control to 33 min for unneutralized and 27 min for neutralized blends. Sensory evaluation of the product revealed that breads containing up to 5% pomace were acceptable.

AB:   This study investigated whether the risk to birds from pesticide-treated cereal seed could be reduced by increasing sowing depth and hence reducing the density of seed exposed on the soil surface. Results are presented from both commercially farmed fields and experimental field trials on light fenland soils in England. Farmers' intended sowing depth for winter wheat varied considerably (20-60 mm) and often exceeded the recommended depth. The density of exposed seeds on commercial fields and in two experimental sowings was inversely related to actual sowing depth. In the experimental trials, better incorporation was achieved on a fine seedbed than on a rough seedbed drilled at similar depth. Results suggest that the manipulation of the depth of sowing provides satisfactory seed coverage in the centre of fields (mainfield) with a fine seedbed, but it is less effective in rough seedbeds and in the margins (headlands). In trials, deep sowing (46-50 mm) gave better yields than shallower sowings (20-36 mm). An estimated, risk index to woodpigeons (Columba palumbus) and house sparrows (Passer domesticus) showed that increasing the depth from 25 to 40-55 mm reduced the risk by a factor of 3-15 in the mainfield but a lower reduction in risk was achieved in the headlands. Potential risks to birds can therefore be significantly reduced by feasible increases in sowing depth using standard seed drills, at least on light fenland soils.

AB:   Field experiments were conducted in Louisiana over 2 yr to evaluate the influence of full-season interference from johnsongrass, common cocklebur, or hemp sesbania at densities of 2.5, 0.5, and 2.0 plants m-1 of row, respectively, and simulated insect defoliation of soybean on weed and soybean growth. Defoliation at R2 (full bloom) and R5 (beginning seed development) soybean growth stages was accomplished by removal of zero, one, or two leaflets per soybean trifoliate, which approximated 0, 33, and 66% defoliation, respectively. Height and dry weight of all weeds were not affected by soybean defoliation level or defoliation stage. Soybean height 3 wk after defoliation at R5 was not influenced by weed interference, soybean defoliation level, or defoliation stage in either year. Averaged across soybean defoliation levels and stages in 1994, johnsongrass, common cocklebur, and hemp sesbania reduced soybean yields 30, 15, and 14%, respectively. In 1995, johnsongrass reduced soybean yield 35%. As soybean defoliation level increased, a linear decrease in soybean yield was observed. Averaged across weeds and soybean defoliation stages, 33 and 66% defoliation reduced soybean yield 6 and 20% in 1994 and 12 and 33% in 1995, respectively. Defoliation at R5 resulted in 10% lower yield than defoliation at R2 in one of two years. Yield reduction due to combinations of weeds and soybean defoliation was additive.

AB:   Field studies were conducted at two locations near Manhattan, KS, in 1994 and 1995 to determine the influence of density (0.5, 1, 2, 4, and 12 plants m(-1) row) and time of emergence on redroot pigweed growth in monoculture or with sorghum. Redroot pigweed was seeded at sorghum planting and at the three- to four-leaf stage of sorghum in plots with sorghum or alone. When redroot pigweed grew with sorghum, dry matter and seed production were reduced with later times of emergence. In monoculture, there was no reduction in dry matter or seed number between the emergence dates studied. Redroot pigweed dry matter and seed production per plant were reduced as plant density increased for plants grown in monoculture. The same trend was observed for redroot pigweed grown with sorghum that did not emerge early relative to sorghum. Plants grown at low density exhibited more lateral growth than when grown at higher densities because of intraspecific competition.

AB:   Mechanisms of resistance to infection by the fungus Aspergillus flavus and accumulation of aflatoxin were studied in kernels of resistant (GT-MAS:gk, Mp420) and susceptible (Pioneer 3154, Deltapine G-4666) com genotypes. Proteins from kernel extracts of com genotypes were analyzed by several methods of polyacrylamide gel electrophoresis. Consistent differences in protein profiles were detected among genotypes. Several proteins were unique to or present in greater concentration in resistant genotypes, whereas others were present only in susceptible genotypes. Extracts of resistant kernels showed markedly greater antifungal activity against A. flavus than did susceptible kernel extracts. Results from the present study suggest a role for kernel proteins in resistance to A. flavus infection and aflatoxin contamination in corn genotypes GT-MAS:gk and Mp420.

AB:   Intensively managed crop systems are normally dependent on nitrogen input to maximize yield potential. Improvenments in nitrogen-use efficieney (NUE) in crop plants may support the development of cropping systems that are more economically efficient and environment friendly. The objective of this study was to map and characterize quantitative trait loci (QTL) for NUE in a maize population. In preliminary experiments, inbred lines contrasting for NUE were identified and were used to generate populations of F2:3 families for genetic study. A total of 214 F2:3 families were evaluated in replicated trials under high nitrogen (280 kg/ha) and low nitrogen (30 kg/ha) conditions in 1996 an 1997.     Analysis of ear-leaf area, plant height, grain yield, ears per plant, kernels number per ear, and kernel weight indicated significant genetic variation among F2:3 families. The heritability of these traits was found to be high h2 = 0.57-8). The mapping pupulation were genotyped using a set of 99 restriction fragment length polymorphism (RFLP) markers. A linkage map of these markers was developed and used to identify QTL. Between two and six loci were found to be associated with each trait. The correspondence of several genomic regions with traits measured under nitrogen limited conditions suggests the presence of QTL associated with NUE, QTLs will help breeders to improve their maize ideotype of a low-nitrogen efficiency by identifying those constitutive and adaptive traits involved in the expression of traits significantly correlated with yield, such as ear leaf area and number of ears per plant.

AB:   Chlorophyll meters have been used to estimate leaf chlorophyll content, and therefore nitrogen (N) status and fertilization requirements for several crops. However, until now C4 forage grasses have not been investigated in this regard. A field study was conducted in 1995 and 1996 to evaluate the potential of chlorophyll (SPAD) meter readings to determine switchgrass N concentration and herbage yield. Meter readings were taken on the top most fully expanded leaves of switchgrass grown on a free draining sandy clay loam soil (St Bernard, Typic Hapludalf) fertilized at 0, 75, or 150 kg N ha-1. The switchgrass was either cut at the end of the season or every four or six weeks. Herbage N concentration in uncut stands declined with time while SPAD readings increased to a mid-season maximum, beyond which they declined rapidly. The relationship between N concentration and SPAD readings was linear (r2=0.62-0.93; p<0.01) for the cut systems. Except for the 1st cut under the 4-week harvest regime, there were positive correlations between dry matter yield and SPAD meter readings (r2=0.58-0.96; p<0.01). These results indicate that SPAD meter readings can be used to measure N concentration and/or monitor N availability for seed production, and when N is the limiting factor, to estimate yield of switchgrass (Panicum virgatum L.).

AB:   The dispersal potential of Xanthomonas oryzae pv. oryzae, causal agent of bacterial blight of rice (Oryzae sativa), was investigated through measurement of primary disease gradients. Plants within individual hills of rice were inoculated, and the number of new lesions in the primary generation of dispersal from these inoculated sources was counted. Two dispersal models that can describe the number of infections at the source (the Kiyosawa and Shiyomi and the modified Gregory) were fit to the lesion counts. Estimated gradient slopes were similar in the 2 years of the study for both gradient models. However, the Kiyosawa and Shiyomi model gave a better fit in both years, as indicated by higher coefficients of determination and significances of slopes and by a more random pattern of residuals. Primary disease gradients were very steep, with half-distances (distances over which lesion numbers are calculated to decrease by half) estimated from the Kiyosawa and Shiyomi model of 0.091 and 0.081 m in 1994 and 1995, respectively. Splash dispersal of X. oryzae pv. oryzae is the most likely explanation for both the steep slopes measured and the superior fit of the Kiyosawa and Shiyomi model over the modified Gregory model.

AB:   Grain feeding often causes a decrease in ruminal pH, and experiments were conducted to define the role of pH in regulating the acetate to propionate ratio and production of CH4. Cows that were fed 90% concentrate had lower ruminal pH values (6.22 vs. 6.86), higher VFA concentrations (85 vs. 68 mM), and lower acetate to propionate ratios (2.24 vs. 4.12) than did cows that were fed forage only. When mixed ruminal bacteria from cows that were fed 90% concentrate or 100% forage were incubated (48 h) with hay (10 g/L) or cracked corn (5 g/L) in a medium containing bicarbonate (38 mM) and tricarballylate (50 mM), the final pH values were less than 0.3 units lower than the initial pH. At final pH values less than 5.7, hay fermentation was inhibited, the acetate to propionate ratio and CH4 production declined more than twofold, and the inoculum source was without effect. Small amounts of H2 were detected at pH values less than 5.5. Total VFA production from cracked corn decreased when pH declined, but only if the inoculum was obtained from cows that were fed 90% concentrate. The acetate to propionate ratio of cracked corn incubations declined from 1.2 to 0.6 when final pH was decreased from 6.5 to 5.3, and CH4, as a percentage of total VFA production, also decreased. At pH values less than 5.3, the acetate to propionate ratio of cracked corn increased more than fourfold, and large amounts of H2 could be detected. Over the final pH range of 6.5 to 5.3, CH4 production was highly correlated with acetate to propionate ratio, which was dependent on pH and substrate (CH4 = 0.02 + 0.05 pH; r2 = 0.80). Calculations based on the differences between pH 6.5 and 5.8 indicated that as much as 25% of the decrease.
       in acetate to propionate ratio could be explained by the effect of pH alone.

AB:   The actin binding protein profilin has dramatic effects on actin polymerization in vitro and in living cells. Plants have large multigene families encoding profilins, and many cells or tissues can express multiple profilin isoforms. Recently, we characterized several profilin isoforms from maize pollen for their ability to alter cytoarchitecture when microinjected into living plant cells and for their association with poly-L-proline and monomeric actin from maize pollen. In this study, we characterize a new profilin isoform from maize, which has been designated ZmPRO4, that is expressed predominantly in endosperm but is also found at low levels in all tissues examined, including mature and germinated pollen. The affinity of ZmPRO4 for monomeric actin, which was measured by two independent methods, is similar to that of the three profilin isoforms previously identified in pollen. In contrast, the affinity of ZmPRO4 for poly-L-proline is nearly twofold higher than that of native pollen profilin and the other recombinant profilin isoforms. When ZmPRO4 was microinjected into plant cells, the effect on actin-dependent nuclear position was significantly more rapid than that of another pollen profilin isoform, ZmPRO1. A gain-of-function mutant (ZmPRO1-Y6F) was created and found to enhance poly-L-proline binding activity and to disrupt cytoarchitecture as effectively as ZmPRO4. In this study, we demonstrate that profilin isoforms expressed in a single cell can have different effects on actin in living cells and that the poly-L-proline binding function of profilin may have important consequences for the regulation of actin cytoskeletal dynamics in plant cells.
