Our lab is interested in studying how plants sense and respond to environmental stresses such as high soil salinity, alkalinity and drought. Particularly, we are interested in understanding regulation of Ca2+ signaling and pH homeostasis under these stresses in plants.
Our researches focus on genetic and molecular characterization of Arabidopsis mutants that are altered in response to environmental stimuli. The goals are to elucidate the plant signaling pathways in response to environmental stresses and to identify key components that can potentially be engineered for improvement of crop plants response to the stresses.
