A newly-discovered Cd-hyperaccumulator Solanum nigrum L.

A systematic investigation was conducted to screen for cadmium-hyperaccumulator from 54 species in 20 weed families using outdoor pot-culture experiment and small-scale field experiment. The results from the outdoor pot-culture experiment showed that Cd concentrations in the stems and leaves of Solanum nigrum L. growing in a soil spiked with 25 mg/kg Cd were up to 103.8 and 124.6 mg/kg (DW), respectively, which was greater than 100 mg/kg, minimum Cd concentration for a Cd-hyperaccumulator. The Cd enrichment factor (EF, concentration ratio in plant to soil) in shoots was as high as 2.68. Moreover, Cd accumulation in shoots was greater than that in roots (TF, concentration ratio in shoots to roots) and the plant biomass growth was not inhibited at the Cd concentrations tested compared with the control. The results of the small-scale field experiment also showed that the characteristics of Cd accumulation in S. nigrum were all consistent with the characteristics of Cd-hyperaccumulators. Thus S. nigrum can be classified as a Cd-hyperaccumulator. This work is important for further research in the areas of hyperaccumulators screening, and plant-tolerance physiology and evolution. It provides a patentable new plant species for phytoremediation of Cd-con- taminated soils.

30 Arabidopsis thaliana as a Model for Studying Mechanisms of Plant Cold Tolerance

Plants vary widely in their ability to tolerate cold temperatures. Many species from tropical and subtropical regions are chilling-sensitive (Lyons 1973; Levitt 1980). Such plants suffer a wide range of damage, ranging from loss of vigor to death, when temperatures drop below about 10°C. In contrast, plants from temperate regions are not only chilling-tolerant, but many can survive freezing at high subzero temperatures (Sakai and Larcher 1987). Moreover, many chilling-tolerant plants increase in freezing tolerance in response to low nonfreezing temperature, a process known as cold acclimation (Levitt 1980; Sakai and Larcher 1987). Nonacclimated wheat and rye, for example, are killed at about −5°C, but after cold acclimation, they can survive temperatures as low as about −20°C and −30°C, respectively. A major challenge for plant scientists interested in low-temperature biology is to determine the molecular bases for plant chilling and freezing tolerance. Why are certain plants such as rice and cucumber sensitive to chilling temperatures whereas plants such as wheat and rye are not? Why is it that the common potato, Solanum tuberosum, cannot cold-acclimate although its close tuber-bearing relative, Solanum commersonii, can? What is the molecular basis for the enhancement of freezing tolerance that occurs with cold acclimation? Considerable effort has been directed toward addressing these and related questions, and much has been learned. However, our understanding of the underlying bases for chilling sensitivity and freezing tolerance remains at an elementary level. We cannot yet answer the questions posed above, for instance, or rationally design from first principles a.
Db-cAMP, forskolin or 2’-d3’-AMP infuence on proliferation of Raphanus sativus root meristem cells

Abstract — Cyclic AMP is a one of the main factors regulating cell proliferation in animals. The role of this second messenger in plant cell cycle control is still much less understood compared to animal or even yeast cells. In this work we checked if cAMP might affect Raphanus sativus root meristem cell proliferation. The studies were conducted on 2-day old seedling roots of Raphanus sativus L. The mitotic index (MI) and radioactive thymidine labelling index (LI) were analyzed after 4-, 8- and 24-hour incubation with 50 μM solutions of db-cAMP (cAMP analogue) and of forskolin or 2’-d3’-AMP (cAMP enzyme synthesis stimulator or inhibitor, respectively) and after postincubation without these substances. All the tested substances are known to modify cAMP level in cells: db-cAMP and forskolin increase and 2’-d3’-AMP decreases intracellular cAMP level. We observed that: 1) increase in cAMP level delayed while decrease accelerated cell transition to S phase; 2) increase in cAMP level accelerated while decrease inhibited initiation of mitosis; 3) removal of db-cAMP and forskolin from the medium enhanced the number of cells starting both replication and mitosis while lack of 2’-d3’-AMP transiently reduced the number of dividing cells. These results seem to suggest that cAMP can be involved in the radish cell cycle transition both at the replication and mitosis levels and its different concentrations are needed for the commencement of DNA replication and mitosis.
STUDIES ON VIRULENCE REACTIONS OF LOCAL ISOLATES OF XANTHOMONAS ORYZAE PV. ORYZAE

Local isolates of Xanthomonas oryzae pv. oryzae were collected from different rice producing areas of Pakistan and evaluated for their virulence on 12 rice lines viz., IRBB1, IRBB2, IRBB3, IRBB4, IRBB5, IRBB7, IRBB8, IRBB10, IRBB11, IRBB13, IRBB14 and IRBB21. The ability of an isolate to cause lesions with different lengths across the lines was interpreted as virulence. Isolates that were consistently associated with high or low virulence were differentiated. Isolates produced lesions of different sizes on different rice lines. Five virulence groups (races) were identified based on the virulence of the bacterial isolates on these lines. No single gene tested was found to be resistant against all virulence groups prevalent in Pakistan. The results of this study will facilitate the breeders in deployment of effective resistance genes against X. oryzae pv. oryzae strains prevalent in Pakistan.

To understanding of the mechanisms of DNA deactivation in ion therapy of cancer cells

Changes in the medium of biological cell nucleus under ion beam action is considered as a possible cause of cell functioning disruption in the living body. As the most long-lived molecular product appeared in the cell after the passage of high energy ions, the hydrogen peroxide molecule is picked out. The possibility of the formation of stable complexes of hydrogen peroxide molecules with active sites of DNA nonspecific recognition (phosphate groups of the double helix backbone) is studied, and the formation of stable DNA-peroxide complexes is considered. Due to the negative charge on the oxygen atoms of DNA phosphate group in solution the counterions that under natural conditions neutralize the double helix have been also taken into consideration. The complexes consisting of oxygen atoms of DNA phosphate group, H2O2 and H2O molecules, and Na + counterion have been considered. Energy of the complexes have been determined based on the electrostatic and van der Waals interactions within the approach of atom-atom potential functions. The stability of various configurations of molecular complexes has been estimated. It has been found that hydrogen peroxide molecules can form the stable complexes with phosphate groups of DNA and counterions which are no less stable than the complexes with water molecules. It is shown that the formation of stable complexes of H2O2–Na + –PO − can be detected experimentally by the observation of specific DNA vibrations in the low-frequency Raman spectra. The interaction of H2O2 molecule with phosphate group of the double helix backbone can block the processes of DNA biological functioning and induce the deactivation of the genetic apparatus of the cell. Thus, the new channel of high-energy ions action on living cell has been proposed.
Experimental Methods for Use with Lambda

INTRODUCTION This paper is addressed particularly (but not exclusively) to those who use λ as a vector for cloning genes of other organisms. In it we describe techniques for growing and purifying phage and offer a brief menu of tests that are useful for verification of genetic characters found in some widely used vectors. We also suggest methods for simple strain construction, mutagenesis, DNA purification, and in vitro DNA packaging. Alternative and overlapping procedures can also be found (Miller 1972; Davis et al. 1980; Maniatis et al. 1982; Berman et al. 1983). We emphasize that the choice of route is often a matter of individual preference and that methods can and should be varied to suit the particular phage strain, laboratory conditions, and the convenience of the investigator. We have indicated why certain manipulations are to be preferred or avoided, but we warn the reader that the reasons are often speculative and are presented to demystify our subject rather than to inhibit experimentation. GROWTH AND STORAGE OF BACTERIAL HOST STRAINS The commonly used hosts for the growth of phage λ are derivatives of Escherichia coli K12. Those few strains to which particular reference is made in this paper are given in Table 1. All known genes of E. coli K12 and their symbols are listed by Bachmann and Low (1980). For the titration and propagation of λ , bacteria are best grown in a rich medium, such as tryptone broth, with aeration at 37°C, and used when they have reached a.
Antihyperlipidemic, antioxidant and weightlowering effects of “Vitalplant”

Abstract BACKGROUND: “VITALPLANT” medicinal plant mixture, aimed at body weight regulation and metabolism enhancement was formulated in order to be incorporated as an ingredient in functional food formulations on the basis of known biological activity of the alder buckthorn bark, peppermint, caraway and parsley. METHODOLOGY: The body weight-lowering potential, hypolipidemic effects and antioxidant activity of “Vitalplant” mixture were examined on five groups of male Wistar rats on different food regimes for 14 weeks. RESULTS: “Vitalplant” mixture supplementation caused an increase in food intake, but induced a decrease in body weight gain. The lipid status and atherogenic index (AI) were significantly improved in “Vitalplant” mixture supplemented hyperlipidemic (HF) groups in comparison to HF group. “Vitalplant” mixture was able to influence the activity of antioxidant enzymes and to protect erythrocytes of the rats fed the HF diet from oxidative damage, which was indicated by significantly lower malondialdehyde (MDA) levels in “Vitalplant”- HF groups in comparison to the HF group. CONCLUSION: “Vitalplant” mixture seemed to be beneficial for the reduction of body weight and improvement of antioxidant status of the erythrocytes, and its antihyperlipidemic property was highly active for enhancing the profile of plasma lipids in rats.

SEASONAL CHANGES IN ABUNDANCE AND COMPOSITION OF DIATOMS IN THE SUYUNG BAY, PUSAN

The present paper deals with the seasonal changes in abundance and composition of diatoms in the Suyung Bay, Pusan, Korea. This study was carried out from August 1966 through July 1967 As a result of the present study, 123 species of diatoms were Identified. While the highest number of diatoms (2,554,000 cells per liter) was recorded in April of 1967, the lowest number (20,400 cells per liter) appeared in December of 1966. In genera the standing stock of diatoms was high in spring and early fall and was low in late fall and winter. Two genera of the diatoms, Chaetoceros and Skeletonema, occupied a great portion of the diatom population throughout the course of this study. The following genera also appeared abundantly: Asterionella, Eucompia, Leptocylindrus and Nitzschia.
Uwebraunia and Dissoconium, two morphologically similar anamorph genera with distinct teleomorph affinity

Crous, P. W. , L. Hong, M. J. Wingfield, B. Wingfield & J. C. Kang (1999). Uwebraunia and Dissoconium, two morphologically similar anamorph genera with different teleomorph affinities. Sydowia 51(2): 155-166. More than 20 anamorph form genera, including Uwebraunia, have been linked to Mycosphaerella. The diversity of anamorphs associated with Mycosphaerella has led to hypotheses that the genus is either polyphyletic, or that the features used to separate anamorphs are indicative of natural lineages within Mycosphaerella. Uwebraunia is morphologically similar to Dissoconium, a genus suspected to include species hyperparasitic on other fungi. Phylogenetic analysis of 5.8S, ITS! and ITS2 rDNA operon of several Mycosphaerella spp. with Uwebraunia, Dissoconium and other anamorphs, as well as species of Ramulispora (Tapesia teleomorph), using Mycocentrospora (teleomorph unknown) as the outgroup taxon, identified three clades. One major clade represented species of Mycosphaerella sensu stricto, comprising several subclades that correlate with the various anamorph form-genera. The other two clades were distinct from the larger Mycosphaerella clade, and represented a smaller clade with Dissoconium anamorphs, and a Tapesia clade with Ramulispora anamorphs. Uwebraunia was shown to include two species representing Mycosphaerella anamorphs. A third species was synonymous with Dissoconium dekkeri, forming a clade separate from Mycosphaerella sensu stricto. Species of Dissoconium are thought to be hyperparasitic on other fungi, whereas species of Uwebraunia are apparent plant pathogens. These findings suggest that divergence occurred in the Mycosphaerella lineage, followed by convergent evolution of morphological form, which accounts for the similar anamorphs.
Nesting Success of a Disturbance‐Dependent Songbird on Different Kinds of Edges

We compared the nesting success of a disturbance‐dependent species, the Indigo Bunting ( Passerina cyanea), on different kinds of habitat edges in five sites (225 total nests) in southern Illinois from 1989 to 1993. Nest predation rates along agricultural and abrupt, permanent edges (e.g., wildlife openings, campgrounds) were nearly twice as high as rates along more gradual edges where plant succession was allowed to occur (e.g., treefalls, streamsides, gaps created by selective logging ). Levels of brood parasitism by Brown‐headed Cowbirds ( Molothrus ater) varied significantly among sites and years, but not among edge types. Clutch sizes, however, were significantly smaller at agricultural edges where nest predation rates were also high, which suggests either decreased food availability or a population dominated by younger and/or lower‐quality ( poor condition) birds. The results of this study illustrate the need to reevaluate management practices (e.g., wildlife openings) that are designed to promote populations of disturbance‐dependent wildlife.
Influence of Bacillus subtilis and acetic acid on Cobb500 intestinal microflora.

The beneficial modes of probiotic action include regulation of intestinal microbial homeostasis, stabilization of the gastrointestinal barrier function expression of bacteriocins and interference with the ability of pathogens to colonize and infect the mucosa. Organic acids as feed additives have been used to reduce or eliminate pathogenic bacteria and fungal contamination, control microbial growth and reduction of microbial metabolites. The aim of this study was to determine the effect of Bacillus subtilis , acetic acid and their combination on the intestinal microflora of broiler chickens (Cobb 500). The experiment was carried out on 4 groups each contains 100 chicks as follows: control (without addition), treatment 1 (acetic acid), treatment 2 ( Bacillus subtilis ) and treatment 3 (acetic acid + Bacillus subtilis ). Six samples from each group were selected as a sample (mixed sex). The highest average number of log CFU.g -1 Lactobacillus sp. was in the treatment 3 – 7.11 log CFU.g -1 and the lowest was in the control group – 6.85. The highest average number of log CFU.g -1 Enterococcus sp. was in the treatment 2 – 7.17 log CFU.g -1 and the lowest was in the control group – 5.65. In both observing additions of Bacillus subtilis and acetic acid increase the number of log CFU.g -1 Lactobacillus sp. and Enterococcus sp. compared with control group. The lower average number of log CFU.g -1 coliform bacteria was in the treatment 2 – 5.9 log CFU.g -1 and the higher was in control group – 6.98. The additional supplement decreased the number of log CFU.g -1 coliform bacteria in the treatment groups compared with the control.
