Adaptation of plants to abiotic stress

I have been involved in looking at adaptations of plants to drought, salinity and heavy metal stress at the cellular, and molecular level for over three decades. More recently since the last five years, I have been interested in looking at glutathione homoeastasis and the links between heavy metal stress and oxidative stress in rice and groundnut seedlings. Our group has now shifted focus to using biotechnological approaches to enhance salinity tolerance of major crops like Rice
