Research Interests
 
        Polarity is a fundamental feature of the cells and can manifest itself both in overall morphology and in unequal distribution of molecular components. The establishment and maintenance of cell polarity are required for asymmetric cell division (ACD), an indispensable mechanism for multi-cellular organisms to generate cellular diversity by producing daughter cells with distinctive identities from a single mother cell. Studies on the plant-specific protein BASL (Breaking of Asymmetry in the Stomatal Lineage) provided strong evidence that plant cells have the capability to polarize non-transmembrane proteins and utilize polarized protein distribution to regulate asymmetric cell division (Dong, et al., 2009). During the past years, we established a positive feedback loop between BASL and a mitogen-activated protein kinase (MAPK) signaling cascade that promotes cell polarity. Our recent research identified additional polarized proteins that are key to establish cell polarity and/or enable stomatal ACD. Our research is dedicated to 1) uncovering the fundamental principles that govern cell polarization and ACD and 2) elucidating the mechanisms underpinning the connections among cell polarization, ACD, and cell differentiation using stomatal development as a model system.
