Profile
Our lab’s research focuses on designing nutrient-rich high-yielding crops such as rice and lentil by discovering novel traits and genes through multi-OMICs approach. Improved crop varieties responsive to available resources with high resource use efficiency, and efficient nutrient recycling could sustain food and nutritional security. We explore natural genetic diversity and mutant populations to identify trait(s) for resource responsiveness, climate resilience, and a fine balance between assimilate-nutrient accumulation in grains. Key focus areas include source-sink dynamics, photosynthesis, respiration and tolerance to stress combinations prevalent under changing climate.
Current Focus Areas
Understanding the source-sink dynamics to improve crop yield and grain nutrition
Crop response to combination of multiple abiotic and biotic stress combinations
Photosynthesis and Respiration (carbon use efficiency)
High throughput crop phenotyping for trait discovery
Genome-wide association study
