A Sensitive PCR‐Based Assay to Detect Neotyphodium Fungi in Seed and Plant Tissue of Tall Fescue and Ryegrass Species
Authors: Dombrowski James E. , Baldwin James C. , Azevedo Mark D. , Banowetz Gary M.
Published: March 2006

A polymerase chain reaction (PCR)‐based method for detection of Neotyphodium endophytes in seed and plant tissue from tall fescue (Festuca arundinacea Schreb.), Italian (Lolium multiflorum Lam.), and perennial (Lolium perenne L.) ryegrasses was developed. The primers were designed to amplify products from a conserved region of the Neotyphodium spp. tubulin 2 gene which is present in N. coenophialum (Morgan‐Jones and W. Gams) Glenn, C.W. Bacon, and Hanlin (endophyte of tall fescue), N. lolii (Latch, M.J. Chr., and Samuels) Glenn, C.W. Bacon, and Hanlin (endophyte of perennial ryegrass), and N. occultans C.D. Moon, B. Scott, and M.J. Chr. (endophyte of Italian ryegrass). PCR yielded the expected amplification products from infected seed lots for tall fescue (358 base pairs [bp]), Italian ryegrass (364 bp), and perennial ryegrass (370 bp). Based on DNA mixture tests and bulk seed analysis, the PCR assay was sensitive enough to detect as little as one infected seed per 50 seeds tested. In addition, the primer set detected the Neotyphodium spp. endophyte in all plant tissues except roots. Comparison of the PCR‐based assay to microscopic examination and immunoblot detection of endophytes in seed lots showed that all three methods compared favorably to one another. However, none of the three methods could distinguish between viable and nonviable endophyte in seed. This PCR method provides an accurate, sensitive approach for detecting the presence of the endophyte in these grasses, while maintaining enough specificity to discriminate Neotyphodium spp. from related fungal contaminants such as ergot [Claviceps purpurea (Fr.:Fr.) Tul.].
Recurrent Selection in a Synthetic Brachiariagrass Population Improves Resistance to Three Spittlebug Species
Authors: Miles J. W. , Cardona C. , Sotelo G.
Published: March 2006

Spittlebugs (Homoptera: Cercopidae) are important pests of forage grasses in the genus Brachiaria (Trin.) Griseb. throughout the neotropics. Results of recurrent selection on resistance to spittlebugs in a synthetic brachiariagrass population are reported. The population was synthesized by recombining sexual hybrids obtained from crosses between a tetraploidized sexual ruzigrass (B. ruziziensis Germain & Evrard) biotype and nine natural apomictic tetraploid accessions of signalgrass (B. decumbens Stapf) and palisadegrass [B. brizantha (A. Rich.) Stapf]. The first three selection cycles were on resistance to a single Colombian spittlebug species [Aeneolamia varia (F.)], and the final two cycles simultaneously on resistance to A. varia and to two additional Colombian spittlebug species [A. reducta (Lallemand) and Zulia carbonaria (Lallemand)]. Selection was based on survival of spittlebug nymphs feeding on artificially infested, greenhouse‐grown plants. From C2 to C6, mean survival of A. varia nymphs on selected genotypes dropped from 55.6 to 7.0%. Tetraploid sexual clones with combined high levels of resistance to all three spittlebug species have been obtained. The effectiveness of this resistance against spittlebug species not occurring in Colombia needs to be determined, and its expression in crosses with spittlebug‐susceptible, apomictic genotypes needs to be assessed.
Improvement of a Maize Population by Full‐Sib Selection Alone versus Full‐Sib with Selection during Inbreeding
Authors: Pixley Kevin V. , Dhliwayo Thanda , Tongoona Pangirayi
Published: March 2006

Maize (Zea mays L.) improvement involves formation, evaluation, selection, and recombination of genetically variable families or inbred lines, and because cultivars must combine many desirable traits, the process can be complicated and lengthy. This study compared 12 experimental open‐pollinated varieties (OPVs) developed from maize population Pool 9A by two approaches, full‐sib (FS) selection alone and FS selection combined with inbreeding with selection for Maize streakvirus (MSV) resistance. The experimental OPVs were evaluated in 13 environments in Africa, including three sites with artificial MSV inoculation. Full‐sib selection combined with inbreeding and selection for MSV resistance [with mild selection for gray leaf spot resistance (GLS, caused by Cercospora zeae maydis Tehon & Daniels)], reduced ear height and reduced days to flowering] resulted in OPVs with similar grain yield but superior MSV resistance (P < 0.01), fewer days to anthesis (P < 0.01), and lower ear height (P < 0.05) than OPVs developed by FS selection alone. Each generation (from S0 to S3) of inbreeding with selection resulted in OPVs that were 16, 8, 2, and 1% improved for MSV and GLS resistance, ear height, and days to anthesis, respectively. Our results demonstrate improvement of a maize population for MSV resistance and other traits by selection during inbreeding (from S0 to S3), without negative impact on gains for grain yield achieved by evaluation and selection among the progenitor FS families.
Response of Stored Potato Seed Tubers from Contrasting Cultivars to Accumulated Day‐Degrees
Authors: Struik P. C. , van der Putten P. E. L. , Caldiz D. O. , Scholte K.
Published: March 2006

In potato (Solanum tuberosum L.), the accumulated day‐degrees (temperature sum, calculated by accumulating the daily temperatures) from dormancy break until seed tuber use has been suggested as an indicator of the physiological status of the seed. We tested whether similar temperature sums differing in timing of a short period of high temperatures gave similar seed performance. Four field experiments were performed in which seed was used that had been exposed to different storage temperature regimes, differing in total temperature sum or in timing or duration of a warm period. Emergence, number of stems, number of tubers, and early and mature tuber yield were assessed. During the storage period, the onset of sprouting was recorded. Cultivars with a high rate of physiological degeneration (“ageing”) were usually sensitive to warm storage during the second part of the storage period, especially if the first 12 to 18 wk of storage had also been warm. This was reflected in reduced emergence (≤10%), low densities of stems (≤0.5 stems m−2) and tubers (≤5 tubers m−2), and low yields, especially with early harvesting (≤20 g m−2). Specific phasing of the warm period could reduce yields to levels even below the yield of the seed tubers exposed to the highest accumulated temperature sum. A higher temperature sum after the end of dormancy advanced and accelerated the process of ageing of seed tubers. Cultivars with a high rate of ageing showed much greater difference between the same temperature sums built up over time in different ways than cultivars with a low rate of ageing. The resulting maximum differences in final fresh tuber yield between seed lots exposed to the same temperature sum could be 65 Mg ha−1 for Astarte (a cultivar with a high rate of ageing) compared with nil for Désirée (a cultivar with a low rate of ageing).
Response of Selected Hard Red Wheat Lines to Imazamox as Affected by Number and Location of Resistance Genes, Parental Background, and Growth Habit
Authors: Hanson Bradley D. , Shaner Dale L. , Westra Philip , Nissen Scott J.
Published: March 2006

Imidazolinone‐resistant (IR) wheat (Triticum aestivum L.) was released for commercial production in portions of the USA in 2002 and has provided growers with a new technology to selectively control winter annual grass weeds. Imidazolinone herbicides inhibit acetolactate synthase (ALS) in susceptible plants; however, IR wheat has an altered target site which confers resistance to these herbicides. The mutation‐derived resistance trait of most commercially available IR winter wheat cultivars is located on the D‐genome; however, winter and spring wheat cultivars with the resistance trait on the A, B, or D genome or on multiple genomes are currently under development. Four groups of near‐isoline wheat with spring or winter growth habit and resistance genes on the B, D, or both B and D genomes were compared for whole plant and ALS enzyme response to imazamox. Biomass accumulation after treatment was similar among B‐ and D‐ genome resistant winter wheat biotypes and was always higher than B‐ and D‐genome resistant spring wheat biotypes. D‐genome resistant spring wheat was more resistant than B‐genome resistant spring wheat and the two‐gene resistant spring wheat had an additive level of tolerance to imazamox compared with single‐gene resistant spring wheat. Growth habit (spring vs. winter) did not affect in vitro ALS activity among B‐ or among D‐genome resistant cultivars; however, D‐genome resistant cultivars had significantly higher in vitro ALS activity in the presence of imazamox compared with B‐genome resistant cultivars regardless of growth habit. D‐genome resistance appears to provide greater tolerance to imazamox compared with B‐genome resistance; however, multiple‐genome resistance likely will be required to consistently avoid crop injury in spring wheat from labeled U.S. rates. Although ALS extracted from winter wheat and spring wheat responded similarly to imazamox, whole plant responses demonstrates that tolerance is affected by factors other than resistance gene location.

Published: March 2006

In this study, the feasibility of the synthesis of various flavor esters catalyzed by a commercial lipase from Candida rugosa was investigated and the process parameters were optimized. Lipase from C. rugosa successfully catalyzed the synthesis of 19 esters. The highest yields, of more than 90 % after 20 h, were observed in the synthesis of short-chain esters, pentyl propanoate, isopentyl butanoate, and butyl butanoate. Increasing the number of carbon atoms of both substrates above 8 caused a significant decrease of the initial reaction rates and the final yields. The enzyme showed surprisingly low affinity towards pentanoic acid and hexanoic acid, compared with the higher homologues, octanoic acid and decanoic acid. In addition to the number of carbon atoms, the structure of the substrates had a significant influence on the enzyme activity. Namely, the activity of the enzyme towards isopropanol was significantly lower compared with n-propanol. Additionally, cis-9-octadecenoic acid was a better substrate than octadecanoic acid, its saturated analogue.
Potentiometric investigation of acid-base equilibria of two new pyrimidine derivatives in various methanol-water media
Authors: Kiliç Hasan , Birol Er
Published: March 2006

The acid-base properties of 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-one (L1) and 1-amino-5-benzoyl-4-phenyl-1H-pyrimidine-2-thione (L2) were investigated potentiometrically at an ionic strength of 0.10M(LiCl) in 19.8, 33.6 and 55.9 % (v/v) methanol-water mixtures at 25.0 ? 0.1 ?C. The apparent dissociation constants (psKa) were calculated for the di-protonated form (L1H2+2 and L2H2+2) of pyrimidine bases, using a software package TITFIT, which were then extrapolated to pure water to derive the dissociation constants in aqueous solution (pKa). The aqueous pKa constants were found to be: L1, pKa1 = 3.76 and pKa2 = 6.95; L2, pKa1 = 3.57 and pKa1 = 6.90. At pH <- 2.00, the dominant species in solution were the protonated form of the amino group substituted at the 1-position, while at a pH around 5.00, they were the protonated form of the pyrimidine ring nitrogen at the 3-position. An effect of intramolecular hydrogen bonding on the psKa values was observed with L1 but not L2. The effects of molecular structure and solvent medium on the psKa values are also discussed.
Dip‐Pen Nanolithography Using the Amide‐Coupling Reaction with Interchain Carboxylic Anhydride‐ Terminated Self‐Assembled Monolayers
Authors: Chi Y. S. , Choi I. S.
Published: March 2006

Herein we report on a new type of dip‐pen nanolithography (DPN), which utilizes an interfacial organic reaction—the amide‐coupling reaction—between chemically activated surfaces and amine ink molecules transferred from an atomic force microscopy tip. As a representative of the chemically activated surfaces that could react with amine compounds, we formed a self‐assembled monolayer terminating in interchain carboxylic anhydride (ICA) groups on gold, and generated chemically derived nanopatterns using alkylamines as ink molecules. Amine inks showed diffusive behavior similar to thiol inks on gold in conventional DPN, and the pattern sizes were controlled by changing the tip dwell times. In addition, nanopatterns of hydrolyzed ICAs were generated by taking advantage of the participation of the water meniscus in the DPN process and the chemical nature of the ICAs.
Latino farmworker perceptions of the risk factors for occupational skin disease
Authors: Arcury Thomas A. , Vallejos Quirina M. , Marín Antonio J. , Feldman Steven R. , Smith Gerrell , Quandt Sara A.
Published: March 2006

Background

Farmworkers in the US constitute a medically underserved population at substantial risk for numerous environmental and occupational health problems. Most US farmworkers are Latino. Skin disease is one health problem to which farmworkers are particularly vulnerable. Interventions to reduce skin disease must be adapted to farmworkers' understanding of such disease, including their beliefs or knowledge of risk factors for skin disease.

Methods

Structured by the Explanatory Models of Illness framework, this analysis uses a qualitative design based on in‐depth interviews with 30 Latino farmworkers (6 females, 24 males) to determine beliefs and perceptions of the causes of common occupational skin diseases in this population. Computer assisted, systematic procedures are used to analyze the verbatim transcripts of these interviews.

Results

Skin disease is a major concern among farmworkers because it affects work, social interaction, and other aspects of their lives. Farmworker beliefs and perceptions of skin disease causation can be integrated into a general model in which perceived risk factors include sun and heat, chemicals, plants, insects, moisture, hygiene, and contagion. Each of these factors is moderated by the individual's personal susceptibility to that cause. The interaction or combination of two or more factors is thought to amplify their individual effects.

Conclusions

The farmworker model of skin disease causation suggests important content for health education to reduce skin disease among farmworkers. Am. J. Ind. Med. 2006. © 2006 Wiley‐Liss, Inc.
Birth seasonality and interbirth interval of captive Rhinopithecus bieti
Authors: Cui Liang‐Wei , Sheng Ai‐Hong , He Shao‐Chun , Xiao Wen
Published: March 2006

This study, which is based on 10 years of birth records, shows that black‐and‐white snub‐nosed monkeys (Rhinopithecus bieti) in captivity display marked birth seasonality. The birth season starts in December and ends in June, with a peak from March to May, and a median birth date of April 10. More male infants than female ones are born in captivity. More males were born at the Kunming Institute of Zoology (KIZ) than at the Kunming Zoo (KZ). Of 17 interbirth intervals (IBIs), 29% were from females that had lost an infant at <1 year of age or experienced stillbirth, and 71% were from females whose infant survived more than 1 year. The mean IBI for the former group (428±SD 87 days) was significantly shorter than that for the latter group (706±71 days), in agreement with reports of other Colobine species. Infant mortality was lower in captivity than in the field, which may reflect the relatively stable food availability and climate in captivity compared to the harsh conditions in the wild. Am. J.

Thermally activated mineralogical transformations in archaeological hearths: inversion from maghemite γFe2O4 phase to haematite αFe2O4 form
Authors: Maki David , Homburg Jeffrey A. , Brosowske Scott D.
Published: March 2006

A series of laboratory experiments were conducted in an effort to understand why magnetic field gradient survey techniques failed to detect hearths at a prehistoric archaeological site in southern California. The study used various methods of environmental magnetism to examine the effects of exposing soil samples to a temperature of 650°C over a period 26 h. Results of the study indicate that the failure was associated with a reduction in soil magnetic susceptibility to below background levels within hearth soils. This reduction was due to high‐temperature transformation of iron oxides from a highly magnetic form to a relatively non‐magnetic form. The reduction in susceptibility is thought to have proceeded via the oxidation of primary (lithogenic) magnetite, Fe3O4 to maghemite, γ Fe2O4 followed by the inversion of maghemite to haematite, αFe2O4. The study suggests that in some instances high temperature inversion can reduce the proportion of ferrimagnetic minerals within a hearth to below initial concentrations (resulting in a negative magnetic field gradient anomaly, the opposite of what is normally expected). A field experiment was also conducted to determine what soil temperatures might be achieved 2 cm beneath a hearth. The experiment recorded temperatures ranging from approximately 400°C to 650°C, with an average temperature of about 470°C. Soil colour changes and magnetic susceptibility enhancement observed at the conclusion of the field experiment indicate that these temperatures were sufficient to activate some mineralogical changes, possibly including inversion to haematite. The implications of high temperature inversion to archaeological prospection are discussed, as is a potential archaeological application. Copyright © 2006 John Wiley & Sons, Ltd.

Solvent Exchange in Thermally Stable Resorcinarene Nanotubes

Published: March 2006

The assembly of C‐methyl resorcinarene into a tubular supramolecular solid‐state structure, its thermal stability, and its hosting properties are reported. Careful control of the crystallisation conditions of C‐methyl resorcinarene and 1,4‐dimethyl‐1,4‐diazoniabicyclo[2.2.2]octane (1,4‐dimethyl DABCO) dibromide leads to a formation of two crystallographically different, but structurally very similar, solid‐state nanotube structures. These structures undergo a remarkable variety of supramolecular interactions, which lead to the formation of 0.5 nm diameter nonpolar tubes through the crystal lattice. The formation of these tubes is templated by suitably sized small alcohols, namely, n‐propanol, 2‐propanol, or n‐butanol. The self‐assembly involves close π⋅⋅⋅π interactions between the adjacent resorcinarenes, and CH⋅⋅⋅π and cation⋅⋅⋅π interactions between the resorcinarenes and the guest 1,4‐dimethyl DABCO dications. The crystals of these supramolecular tube structures are thermally very stable and the included solvent alcohol can be removed from the tubes without breaking the single‐crystalline structure of the assembly. After removal of the solvent molecules the tubes can be filled with other small, less polar solvent molecules such as dichloromethane.

Self‐Supported Chiral Catalysts for Heterogeneous Enantioselective Reactions
Authors: Ding Kuiling , Wang Zheng , Wang Xingwang , Liang Yuxue , Wang Xisheng
Published: March 2006

The development of heterogeneous chiral catalysts for enantioselective reactions is highly desirable in order to overcome some drawbacks of homogeneous catalysts. Different from the conventional approaches by using various types of supports or biphasic systems for the recovery and reuse of homogeneous catalysts, a conceptually new strategy for heterogenization of homogeneous chiral catalysts, that is, a “self‐supporting” approach, has been developed to use homochiral metal–organic coordination polymers generated by the self‐assembly of chiral multitopic ligands with metal ions, and thus obviates the use of any support. In this concept article, the success of this “self‐supporting” strategy will be exemplified in heterogeneous catalysis of asymmetric carbonyl–ene, sulfoxidation, epoxidation, and asymmetric hydrogenation reactions.
A User‐Friendly, All‐Purpose Pd–NHC (NHC=N‐Heterocyclic Carbene) Precatalyst for the Negishi Reaction: A Step Towards a Universal Cross‐Coupling Catalyst
Authors: Organ Michael G. , Avola Stephanie , Dubovyk Igor , Hadei Niloufar , Kantchev Eric Assen B. , O'Brien Christopher J. , Valente Cory
Published: March 2006

We have developed the first user‐friendly Negishi protocol capable of routinely cross‐coupling all combinations of alkyl and aryl centers. The use of an easily synthesized, air stable, highly active, well‐defined precatalyst PEPPSI‐IPr (1; PEPPSI=pyridine‐enhanced precatalyst preparation, stabilization and initiation; IPr=diisopropylphenylimidazolium derivative) substantially increases the scope, reliability, and ease‐of‐use of the Negishi reaction. All organohalides and routinely used pseudohalides were excellent coupling partners, with the use of chlorides, bromides, iodides, triflates, tosylates, and mesylates resulting in high yield of the coupled product. Furthermore, all reactions were performed by using general laboratory techniques, with no glove‐box necessary as the precatalyst was weighed and stored in air. Utilization of this methodology allowed for the easy synthesis of an assortment of sterically encumbered biaryls and druglike heteroaromatics, demonstrating the value of the PEPPSI‐IPr system. Furthermore, this is also the first time Pd–NHC (NHC=N‐heterocyclic carbene) methodology has surpassed the related phosphine‐ligated Negishi processes both in activity and use.

Published: March 2006

The synthesis of NHC‐PdCl2‐3‐chloropyridine (NHC=N‐heterocyclic carbene) complexes from readily available starting materials in air is described. The 2,6‐diisopropylphenyl derivative was found to be highly catalytically active in alkyl–alkyl Suzuki and Negishi cross‐coupling reactions. The synthesis, ease‐of‐use, and activity of this complex are substantial improvements over in situ catalyst generation and all current Pd–NHC complexes. The utilization of complex 4 led to the development of a reliable, easily employed Suzuki–Miyama protocol. Employing various reaction conditions allowed a large array of hindered biaryl and drug‐like heteroaromatic compounds to be synthesized without difficulty.
