Stomatal development, environmental signaling, transcriptional regulation, plant cell and developmental biology
Environment plays a key role in influencing how living organisms grow and develop. Our research aims at understanding the mechanism of this influence using stomata in plants as our model system. Stomata—the essential surface pores that governs gas exchange—provide a powerful system to address this fundamental question at the cell level. We aim to decipher the environmental signalling network that controls the production of stomata using a multidisciplinary approach, from cell biology, biochemistry, genetics to genomics. Besides its values in basic research, the study of stomata, which directly affect photosynthetic capacity and water usage in plants, has implications in agriculture and food production.
