We are investigating the transcriptional and post transcriptional regulatory mechanisms of gene expression cascade activated during biotic stress response in plant. Plants respond to a stress by reprogramming of existing gene expression cascade which provides robustness and specificity to the response. Regulation of initiation of transcription and microRNA (miRNA)-mediated posttranscriptional gene-silencing have crucial roles in this process.

Using tomato plant and various pathogens, and utilizing genomics, molecular biological and plant biotechnological tools our research programmes include Genome-wide analysis of Alternaria stress-responsive microRNAs and their targets Analysis of mechanism of regulation of expression of miRNAs during stress. Studies on molecular signalling associated with disease symptom manifestation. Investigating the signalling cascade leading to the activation of membrane-bound
