    Abiotic stresses like drought and high salinity are the most damaging factors to agricultural productivity worldwide. Functional genomics has played a key role in making plant breeding more efficient in development of crop varieties tolerant to biotic and abiotic stresses. Numerous genes and their products respond to these stresses at transcriptional and translational level. Discovery of these novel genes has been the main objective of all plant breeders. Although many drought responsive genes have been discovered, it is still of great importance to analyse drought-inducible genes and their expression in drought-tolerant crops. In addition to various molecular markers, Expressed Sequenced Tags (ESTs) are currently used as a fast and efficient method of profiling genes expressed in various tissues, cell types or developmental stages. The genes, thus, discovered will be utilized in their transfer to commercially important crops through marker assisted selection or transgenic breeding.

    In the present study, an attempt has been made to assess whether the effect of benzene extract of Ocimum sanctum leaves on the spermatogenic pattern and ultrastructure changes in testis of albino rats. Wistar strain male albino rats were orally administered 250 mg/kg body weight of O.sanctum leaves followed by maintaining suitable controls for 48 days. Results indicate that spermatogenesis was arrested either at the primary spermatocytes or the spermatogonial stages. Damaged seminiferous tubules and abundance of vacuoles of varying size were observed. Total count and diameter of spermatogonia, spermatocytes, spermatids and Leydig cells were reduced. Ultrastructural analysis revealed that intercellular spaces primarily, though not exclusively in the Sertoli cell cytoplasm, degeneration started within the nucleus of spermatocytes and from acrosomal granule or Golgi complex of round spermatids. Bridges between Sertoli cells–spermatocytes or spermatids were disturbed and most of mitochondria of cytoplasm were hypertrophied. Within the cytoplasm degenerating spermatids were with less electron dense matrix and commencement of vacuolization. The results suggest that the effect of benzene extract of O.sanctum leaves on the rat testis may be due to curtailing of androgen supply within the testis through its antispermatogenic and antiandrogenic property.

    In order to facilitate genetic studies in mammalian cells, we developed a cost efficient lipid-mediated plasmid DNA transfection protocol utilizing food oil as a transfer-mediator. The intention was to create and/or improve a cheap and efficient method. Compared to the conventional transfection using commercially available lipofection-specimen, this procedure remarkably enhanced the delivery of a GFP reporter plasmid into HEK293 cells. Our technique of gene delivery is adaptable for large scale production since the costs of the reagent is two to three orders of magnitude cheaper than conventional commercial available reagents.

    A survey was conducted in Nanded and Beed district, for the ethno medicinal plants. The paper documents were prepared from ethnomedicinal uses of wild plant species in Nanded and Beed District. The plants parts are most commonly used in treatment of various diseases are roots, leaves, whole plant bark and seeds. Inspite of vast scientific development in modern age man is looking towards traditional medicines. Due to ethno medicines many diseases are cured like jaundice, snakebite, scorpion bite, leucoderma liver and many more challenging, incurable diseases which are not cured by the modern medical science are cured by traditional medicines. This knowledge still exists in the villages. So interviews of traditional Jantas were taken, the details of plants collected, identified were noted. It is suggested that local forest management with Forest Department and NGOs needs to pay attention for Conservation of commercially important species, with sustainable harvesting methods. The cultivation and detailed assessment of the economically valuable medicinal plants is the demand of present day. Hence it is to be collected, preserved, protected and propagated for future generation.

    This study evaluated the toxicological effects of raw and cooked Mucuna pruriens seeds using its effect on liver enzymes and serum bilirubin (total and conjugated) of white albino Wistar rats in the laboratory. Powdered raw and cooked M. pruriens seed meal were incorporated into the feed of rats at different percent (10,20 and 50%) inclusion levels for the test animals while normal feed was given to the negative control rats for 28 days after which blood samples were collected from each rat for serum analysis. The tests conducted were serum Aspartate Amino Transaminase (AST), Alanine Amino Transaminase (ALT), Alkaline Phosphatase (ALP), Total bilirubin (TB) and Conjugated Bilirubin (CB). The liver function tests revealed that the serum AST, ALT, ALP as well as the total and conjugated bilirubin were significantly (P<0.03) increased in the rats that were fed 10 and 20% raw Mucuna seed meal in the feed and also significantly (P<0.0001) increased in the rat fed with 50% raw Mucuna in the feed when compared to the negative control. Also the liver enzymes and serum bilirubin (total and conjugated) of the rats that received different percent (10,20 and 50%) inclusion levels of cooked M. pruriens seed in the feed were significantly (P<0.05) increased when compared to the negative control group. In all the experiments, the level of the liver enzymes and serum bilirubin increased with increase in the percent level of inclusion in the feed. In conclusion this study suggested that M. pruriens may have hepatotoxic potentials which may be dose dependent and may be reduced by cooking the seeds before incorporation into the feed.

    The present studies have emphasizes on the correction of soil and water quality of china clay mines with the help of organic and inorganic fertilizer and become transfer to like a productive pond. After successful transformation of china clay mines like a productive one, fingerling stages of Indian major carps were released to the mine water and the growth performance was observed with minute care. At the initial stage, mortality rate was high and after acclimation it slowed down. Monthly variation of growth, biochemical composition and nutritional quality were estimated and recorded. After one year culture period the remaining experimental fishes were harvested by cast net and distributed among the local people for tasting the organoleptic quality. They could not find any deviation of taste in between fish reared in china clay mines and in general Indian major carps. Protein and lipid content of experimental fishes (Protein percentage of Catla catla, Labeo rohita and Cirrhinus mrigala was 11.55, 13.04 and 11.02 respectively and the lipid percentage was 4.59, 3.94 and 4.34 respectively) were slightly lower than the fish culture in highly productive pond (Protein percentage of Catla catla, Labeo rohita and Cirrhinus mrigala was 12.83, 14.47 and 11.86 respectively and the lipid percentage was 4.71, 4.23 and 4.52 respectively). There are various factors causing variation of protein and lipid in fish flesh. The factors like food, temperature, size or age, season, maturity, environment etc. are reported to have influencing effect on protein or lipid concentration in fishes. Therefore, moderate deviation of protein and lipid quality does not markedly vary the demand, taste as well as the market value of fish. Statistical analysis of experimental results reveled that the taste, flavour and biochemical composition are highly significant.

    The competitive nodulation ability of a Bradyrhizobium strain is an important property, as strains must compete with other Bradyrhizobia in the rhizosphere for nodulation sites on the host plant. If inoculants strains are to succeed, they must have the ability of competitiveness as well as being effective in symbiosis. The establishment of effective nodulation of soybean plant can be enhanced by using effective and competitive strains of Bradyrhizobium. In the present study 30 isolates of Bradyrhizobium japonicum obtained from semiarid locations were compared for their N2 fixing efficiency based on IAA production, EPS production, nodulation, nodule ARA activity and nodule N content. The isolate obtained from Tiruchengodu SBJ-14 produced maximum of IAA, EPS and ARA activity and this isolate also recorded the highest number of 30.00 nodules plant-1 ARA activity of 215.00 n moles C2H4 formed h-1 g-1 and nodule nitrogen content of 7.44%.

    Aflatoxins, the most frequently studied mycotoxins, are produced by certain Aspergillus species/strains/isolates of fungi. The aflatoxin biosynthetic pathway studies have led to a number of discoveries. Several structural and their enzymes involved in the biosynthesis of aflatoxins have been discovered and purified. Aflatoxin production and contamination of agricultural crops are major causes of economic losses in agriculture. Thus, better methods of characterization/differentiation are required for both aflatoxigenic and non-aflatoxigenic isolates. Polymerase Chain Reaction (PCR)-based, single sequence repeats (SSR) micro satellites analysis has been used successfully in the analysis of DNA relatedness of species of fungi, bacteria, plants and animals. SSR micro satellites analysis present in nuclear and organelles DNA can be used as molecular markers and has wide ranging applications in the field of genetics including kinship and population studies. These Inter simple sequence repeats (ISSR) represent genome region between micro satellite loci. Sequences amplified by ISSR-PCR can be used for delimiting species. Dendograms which evaluate the likeness between different isolates has also been used.

    The effect of lethal concentrations as 0.33 ppm, 0.26 ppm, 0.17 ppm and 0.09 ppm of tributyltin chloride on lipid content in ovary, hepatopancreas, gill and muscle of a freshwater prawn, Macrobrachium kistnensis for 24, 48, 72 and 96 hours respectively has been investigated. The result showed that TBTCl induces significant alteration in lipid metabolic profiles in ovary, hepatopancreas, gill and muscle after exposure to lethal concentration. The depletion in lipid content during exposure of different concentration of TBTCl might be due to its utilization in energy production by oxidation of lipids under the influence of lipase enzyme to derive fatty acids precursor for TCA cycle.

    When HEK293 cells were transfected with a plasmid containing CMV promoter driven human wild-type PRND gene, the doppel protein was diffusely observed at the cytoplasm as seen in cancer cells. The transfected cells incubated with proteasome inhibitor N-acetyl-leucinal- leucinal- norleucinal (ALLN), resulted in apparent accumulation of the doppel protein. Furthermore, an alpha helix domain of the doppel protein appeared to be coimmunoprecipitated with ubiquitin related HSP70 protein. These findings suggested that the cytosolic doppel protein chaperoned with HSP70 could be subjected to ubiquitin proteasome degradation system.

    A simple, economic, and time-efficient stability-indicating, reverse-phase ultra-performance liquid chromatographic (RP-UPLC) method has been developed for analysis of donepezil hydrochloride in the presence of both impurities and degradation products generated by forced degradation. When donepezil hydrochloride was subjected to acid hydrolytic, oxidative, base hydrolysis, photolytic, and thermal stress, degradation was observed after oxidative and base hydrolysis. The drug was found to be stable to other stress conditions. Successful chromatographic separation of the drug from impurities formed during synthesis and from degradation products formed under stress conditions was achieved on a Waters Acquity C18, 50 mm x 2.1mm, 1.7µ particle size column, UV detection 286nm and a gradient elution of trifluoro acetic acid, acetonitrile and methanol as mobile phase. The method was validated for specificity, precision, linearity, accuracy and robustness and can be used for quality control during manufacture and for assessment of the stability of samples of donepezil hydrochloride. To the best of our knowledge, a validated stability indicating UPLC method which separates all the eight impurities disclosed in this investigation has not been published elsewhere. Total elution time was about 8 min which allowed quantification of more than 100 samples per day.

    We have developed an artificial dual promoter cassette system called APRICOT-1-2-3, in which a target gene specific sequence is inserted between inverted two short artificial promoters. A single step PCR protocol has been developed by using this system that allows the production of this cassette in a high throughput manner. Actually, easily prepared APRICOT-1-2-3 constructs induced effective protein expression-silencing for p38MAPK and JNK. The flexibility of this unique design system suggests that additional modification can also easily be introduced into this siRNA expression cassette to improve the convenience applying RNAi.

    Glaucidae is a taxonomic family of colorful sea slugs (blue ocean slugs). This is the first report presenting the occurrence of G. atlanticus and G. marginata in Nagapattinam coastal area, Bay of Bengal coastal shore (South East coast of India). All these animals float on the surface of the ocean being carried by the currents and the winds. Both species of G. atlanticus and G. matginata are closely associated with other open ocean invertebrates such as the Portuguese-man-of-war (Physalia physalis), the wind-sailor (Velella velella) and Porpita porpita. The nematocysts of Physalia pass unharmed through the digestive system and are used as defense system in the papillae. Male animals having its reproductive part (penis) with large looped and hook structure.

    This study was carried out to investigate the therapeutic role of the aqueous extract of Pleurotus florida (PF) on thioacetamide induced hepatotoxicity in rats. Thioacetamide at the dose of 600mg/kg body weight orally produced liver damage in rats as manifested by the significant rise in serum levels of aspartate aminotransferase (AST), alanine aminotransferase (ALT), alkaline phosphatase (ALP), bilirubin, cholesterol and decreases the protein level compared with control. The body and liver weight of each animal was determined, to assess any possible weight gain or loss in experimental animals compared with control groups. Oral administration of aqueous extracts of P. florida (100, 200, 400mg/kg) and silymarin (25mg/kg) once daily for 28 days to thioacetamide treated rats shows lowered significantly where as protein level increased. It also shows a significant increase in body weight and decrease in liver weight. The extract alone treated rats did not adversely affect the serum biochemical estimation. Treatment with P. florida (100, 200, 400mg/kg) of the extract revealed a antihepatotoxic action compared with the rats that were administered thioacetamide alone. This study has shown that the aqueous extract of P. florida possesses antihepatotoxic property.
