Current projects: External calcium and nitric oxide signaling in Arabidopsis
Research Description: My laboratory is interested in the early signaling events by which plants sense environmental signals and decode to give the appropriate responses. Upon perception of external signals, cell surface receptors trigger an increase in cytosolic free calcium concentration, which is mediated by ion channels. Our long-term goals are to identify these receptors and ion channels, isolate their interacting components, and assign molecular functions to them. Currently, we are using multidisciplinary approaches of biophysics, biochemistry, cell biology, molecular genetics, and function genomics to dissect the signaling cascades of external calcium as well as nitric oxide in the model plant Arabidopsis.
