Research Description:

One of the early responses of plants to adverse environmental stimuli is rapid and transient fluxes in the reactive oxygen species (ROS), also called as the oxidative burst. This oxidative burst is an intricate response since different stimuli can activate different subsets of cellular enzymes that produce ROS and other redox-modulated proteins. One of my research interests is in identifying and characterizing redox-regulated stress responsive genes in plants employing genetic, molecular and functional genomics approaches.
