A major aspect of sustaining crop productivity is to protect the plants against diverse insect-pests and pathogens. Plants have a variety of defense responses deployed against insect pests and pathogens. These include the production of chemicals, from small organics to large proteins and enzymes. Our research interest focusses on understanding plant's defense mechanism, the associated signal transduction pathways and the component resistance genes. At present we are working on RNAi mediated strategies, genome editing and introgression of defense genes from wild species for developing insect-pest and pathogen resistance in Brassica oil seeds.
