1. Deciphering the gene regulatory network associated with nutritional quality of rice.

Our research is directed towards the molecular and functional aspects of transcription factor(s) in rice to reveal cellular pathways associated with seed development and maturation. We are investigating the gene regulatory network of seed-related transcription factors, their molecular basis of regulation, and their downstream target that plays a crucial role in determining the rice grain quality.

2. Understanding the cellular signaling and abiotic stress responses in plants

In another project, we are working on stress response and pathways that mediate tolerance/resistance to abiotic stresses in plants. We are mainly interested to understand how abiotic stressors impact seed development and quality. Abiotic stresses substantially affect the global economy by curtailing plant growth and biomass production. These stresses are also relevant to the present scenario of climate change to ensure the food security and safety of the growing human population. We are interested in exploring the physiological, biochemical, and molecular response to abiotic stresses and decode the complex network and the candidate genes involved in stress response.
