 Research Interest
Our program focuses on two major areas of research, namely, improvement of tolerance to abiotic stresses (i.e. drought and salt) in higher plants by improving root traits, and genome sequencing and analyses.
Abiotic Stress Tolerance
Our research interest is in the field of agricultural and plant biotechnogy especially in abiotic stress (drought and salinity) response in plants. Our group focuses on mechanism of root growth and thereby improving abiotic stress tolerance in plant. Phytohormone auxin is the most important regulator of all the stages of root development. We are investigating the nodal point of interaction between auxin and abscisic acid, the hormone that regulates abiotic stress response in plants. Our long-term goal is to use genetic engineering to improve root biomass production and tolerance to abiotic stresses of important crops.
Working with chickpea we identified a number of genes that specifically express at a higher level in drought-tolerant variety in response to drought. To establish the biological functions of the identified genes, we demonstrated that two transcription factors CAP2 and CaZF conferred overall growth, especially of root, and abiotic stress (drought, salinity and heat)-tolerance in transgenic plants. We proposed novel role for a calcium-regulated protein kinase CIPK6. This protein is responsible for shoot to root auxin transport and thereby root-branching at the early seedling stage along with its role in drought-tolerance.
Genome Sequencing
Our laboratory is one of the three Indian centers that sequenced chromosome 5 of tomato genome. We were also involved in whole genome sequencing and analyses of a desi-type chickpea cultivar.
