Research Intersts:  Development of transgenic wheat with increased tolerance against drought and salinity The world population has topped 6 billion people and is predicted to double in the next 50 years. Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. GM foods promise to meet this need in a number of ways. Some benefits of genetic engineering in agriculture are increased crop yields, reduced costs for food or drug production, reduced need for pesticides, enhanced nutrient composition and food quality, resistance to pests and disease, greater food security and medical benefits to the worlds growing population. Currently we have developed transgenic wheat by transferring DREB1A and gdhA genes to improve tolerance against drought and salinity. Gene tagging and development of EMS mutant lines in basmati rice is also going on.
