Research Interests:

Dr. Subramanyam works on phenotypic and molecular characterization of plant-insect interactions in economically important cereal crops and model genomes with special emphasis on wheat and its destructive pests Hessian fly and greenbug. The Subramanyam lab research focuses on two main areas: (i) discovering new and novel sources of insect resistance in wheat and other cereals that can be used in breeding programs for molecular stacking to develop elite resistant cultivars; and (ii) deciphering the molecular basis of plant resistance and insect virulence to develop effective alternate molecular strategies to complement and enhance durability of native resistance. The research team uses multidisciplinary approaches including traditional and next generation ‘omic’ technologies to decipher factors involved in plant resistance to insect pests.
