Asymmetric cell division (ACD) is a fundamental process for the development of multicellularity in both animals and plants. The stomatal lineage cells, which divide and differentiate into pavement cells and stomatal guard cells in the leaf epidermis of Arabidopsis, require strictly controlled asymmetric cell division for stomatal production and patterning. The novel protein BASL (Breaking Asymmetry of the Stomatal Lineage) was identified as the key regulator that links cell polarity to asymmetric cell division in the stomatal lineages. I will present a recently established functional connection between this novel protein and a canonical MAPK singling pathway. In stomatal ACD precursor cells, BASL and the YODA MAPK cascade form a positive feedback loop: BASL polarization requires the MAPK-mediated phosphorylation and activated
