Expression -- Description ? help Back to Top
Source Description
UniprotDEVELOPMENTAL STAGE: Not expressed in meristemoids, but strongly expressed in guard mother cells (GMCs) and in young guard cells (at protein level) (PubMed:17088607). Expressed at the transition to terminal stomatal differentiation, just before and after the symmetric division of stomatal differentiation, being confined to late-stage GMC and to young, still differentiating guard cells (PubMed:24571519). {ECO:0000269|PubMed:17088607, ECO:0000269|PubMed:24571519}.
UniprotTISSUE SPECIFICITY: Resctricted to stomatal cell lineages (at protein level). Expressed in roots, leaves, stems, and flowers. {ECO:0000269|PubMed:12679534, ECO:0000269|PubMed:17088607}.

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}.

UniProtINDUCTION: Inhibited by low relative humidity (LRH) via epigenetic CG methylation, thus leading to a reduced stomatal index. {ECO:0000269|PubMed:22442411}.
