While involved in a functional genomics program, we found that the overexpression of potato (Solanum tuberosum) glyceraldehyde 3-phosphate dehydrogenase (GAPDH) gene in yeast improves its water-deficit stress (drought) tolerance. But, the effect of altered (under and over) expression of GAPDH on water-deficit stress tolerance of higher plants is not yet(More)
Identification of major stress tolerance genes of a crop plant is important for the rapid development of its stress-tolerant cultivar. Here, we used a yeast functional screen method to identify potential drought-tolerance genes from a potato plant. A cDNA expression library was constructed from hyperosmotic stressed potato plants. The yeast transformants(More)
Reverse osmosis (RO) membrane systems are widely used in water purification plants. Reduction in plant performance due to biofilm formation over the membrane is an inherent problem. As quorum sensing (QS) mechanisms of microorganisms have been reported to be involved in the formation of biofilm, ways are sought for quorum quenching (QQ) and thereby(More)
Biofouling is a serious problem on filter membranes of water purification systems due to formation of bacterial biofilms, which can be detrimental to the membrane performance. Biofouling occurs on membrane surface and therefore greatly influences the physical and chemical aspects of the surface. Several membranes including microfiltration, ultrafiltration,(More)
Many rhizobacteria are known to influence several plant growth parameters in many crop species. The influence of rhizobacteria on potato tuber production was reported in few earlier studies but none of the studies explored the molecular mechanism involved in such effects. In the present study, we isolated and identified 13 bacteria from potato rhizosphere(More)
