Plant Ca(2+)ATPases regulate many signalling pathways which are important for plant growth, development and abiotic stress responses. Our previous work identified that overexpression of OsACA6 confers salinity and drought tolerance in tobacco. In the present work we report, the function of OsACA6 in cold stress tolerance in transgenic tobacco plants. The(More)
To overcome the salinity-induced loss of crop yield, a salinity-tolerant trait is required. The SUV3 helicase is involved in the regulation of RNA surveillance and turnover in mitochondria, but the helicase activity of plant SUV3 and its role in abiotic stress tolerance have not been reported so far. Here we report that the Oryza sativa (rice) SUV3 protein(More)
During the efficient genetic transformation of plants with the gene of interest, some selectable marker genes are also used in order to identify the transgenic plant cells or tissues. Usually, antibiotic- or herbicide-selective agents and their corresponding resistance genes are used to introduce economically valuable genes into crop plants. From the(More)
The helicases provide duplex unwinding function in an ATP-dependent manner and thereby play important role in almost all the nucleic acids transaction. Since stress reduces the protein synthesis by affecting the cellular gene expression machinery, so it is evident that molecules involved in nucleic acid processing including translation factors/helicases are(More)
The p68, a prototypic member of DEAD-box protein family, is involved in pre-mRNA splicing, RNA-induced silencing and transcription regulation. However, the role of plant p68 in stress tolerance and molecular targets responsible for this has not been reported. Here, we report the isolation and characterization of salinity-induced pea p68 (Psp68). The(More)
Coping with salinity-induced reduction in crop yield is essential for food security. Human leukocyte antigen-B associated transcript 1 (BAT1) also called as UAP56 is a DExD/H-box protein involved in messenger RNA (mRNA) splicing. Function of plant homologue of BAT1, especially its involvement in stress tolerance, has not been reported so far. Here, we(More)
Indica rice cultivar IR64 is most recalcitrant to regenerate, which affects the transformation efficiency especially when mature seed-derived callus tissues are used as explants. Therefore, a simple, rapid and improved genetic transformation protocol has been developed for the indica rice cultivar IR64 using Agrobacterium-mediated genetic transformation.(More)
Biological nitrogen fixation (BNF) is highly effective in the field and potentially useful to reduce adverse effects chemical fertilisers. Here, Azotobacter species were selected via phenotypic, biochemical and molecular characterisations from different rice fields. Acetylene reduction assay of Azotobacter spp. showed that Azotobacter vinelandii (Az3) fixed(More)
The beneficial fungi are potentially useful in agriculture sector to avail several services to crop plants such as water status, nutrient enrichment, stress tolerance, protection, weed control and bio-control. Natural agro-ecosystem relies on fungi because of it takes part in soil organic matter decomposition, nutrient acquisition, organic matter recycling,(More)
Current soil management strategies are mainly dependent on inorganic chemical-based fertilizers, which caused a serious threat to human health and environment. The exploitation of beneficial microbes as a biofertilizer has become paramount importance in agriculture sector for their potential role in food safety and sustainable crop production. The(More)
