Biological control of plant diseases is strongly emerging as an effective alternative to the use of chemical pesticides and fungicides. Stress tolerance is an important attribute in the selection of bacteria for the development of microbial inoculants. Fourteen salt-tolerant bacteria showing different morphological features isolated from the rhizosphere of maize were evaluated for different plant...
The increasing temperature is going to be more vulnerable for cool season crops like potato which requires an optimum productivity temperature of 18 to 20 °C. Thus, breeding for heat tolerance has become very important. Therefore, some previously used indices for abiotic stress tolerance have been used in our study for screening of high temperature stress tolerance in potato. Three high yielding (Kufri...
In 2011 year research project on breeding spring barley genotypes tolerant to temporary drought stresses has started. The authors’ responsibility was to test the productivity of genotypes derived from different parental forms obtained in scope of the project for a drought tolerance in pot experiment. In the years 2011–2013 three consequtive series of experiments with approximately seventy genotypes...
The present study deals with biomonitoring to know mollusc species as an indicator. In the present study, presence, absence and abundance of particular gastropod and bivalve species were identified in the different banks of river Ganga. The study was carried out at two experimental sites, Sodepur (Exp-1) and Khardah (Exp-2), West Bengal, India as the area exhibits a major sewage water outfall in the...
Lepidium latifolium L., a weed distributed in the Ladakh region of Himalayan range, belongs to Brassicaceae family and reported to withstand low temperature stress <-20°C. RACE primers were designed from EST encoding Ras-related GTP-binding like protein (FG618354) from L. latifolium and full-length LlaRan (GU014818) was obtained. Its cDNA sequence consisted of 672 bp long open-reading frame, 5'UTR...
Salicylic acid (SA), a key signaling molecule in higher plants, has been found to play a role in the response to a diverse range of phytopathogens and is essential for the establishment of both local and systemic-acquired resistance. Recent studies have indicated that SA also plays an important role in abiotic stress-induced signaling, and studies on SA-modulated abiotic tolerance have mainly focused...
Plant glutathione peroxidases are an important class of enzymes which play key roles in the stress adaptability of plants both in context of biotic and abiotic stress pathways. They have been over the years much studied in animals since the catalytic residues are comprised of selenocysteine a variant amino acid which is ribosomally encoded with the help of an RNA structural element known as SECIS...
Two methylotrophic strains of Bina coalmine spoil BNV7b and BRV25 were identified based on physiological traits and 16S rDNA sequence as Methylophilus and Methylobacterium species. The strains exhibited similar carbon utilization but differed in N utilization and their response to the metabolic inhibitors. Methylophilus sp. was less tolerant to salt stress and it viability declined to one tenth within...
