Source Description
UniProtTranscription activator (PubMed:17088607, PubMed:17183265, PubMed:17183267). Together with MYB88 and MYB124, ensures that stomata contain just two guard cells (GCs) by enforcing a single symmetric precursor cell division before stomatal maturity (PubMed:24571519). Together with SPCH and MUTE, regulates the stomata formation. Required to promote differentiation and morphogenesis of stomatal guard cells and to halt proliferative divisions in their immediate precursors. Mediates the formation of stomata (PubMed:17088607, PubMed:17183265, PubMed:17183267). Prevents histone H3K27me3 marks and derepresses stem cell gene expression (PubMed:24654956). {ECO:0000269|PubMed:17088607, ECO:0000269|PubMed:17183265, ECO:0000269|PubMed:17183267, ECO:0000269|PubMed:24571519, ECO:0000269|PubMed:24654956}.
