Source Description
UniProtTranscription factor acting as an integration node for stomata and brassinosteroid (BR) signaling pathways to control stomatal initiation and development (PubMed:22466366, PubMed:28507175). Activates transcription when in the presence of SCRM/ICE1 (PubMed:28507175). Functions as a dimer with SCRM or SCRM2 during stomatal initiation (PubMed:18641265). Required for the initiation, the spacing and the formation of stomata, by promoting the first asymmetric cell divisions (PubMed:25843888, PubMed:25680231, PubMed:19008449). Together with FMA and MUTE, modulates the stomata formation. Involved in the regulation of growth reduction under osmotic stress (e.g. mannitol), associated with a quick decrease of meristemoid mother cells (MMCs) number lower stomatal index and density (PubMed:25381317). {ECO:0000269|PubMed:17183265, ECO:0000269|PubMed:17183267, ECO:0000269|PubMed:18641265, ECO:0000269|PubMed:19008449, ECO:0000269|PubMed:22466366, ECO:0000269|PubMed:25381317, ECO:0000269|PubMed:25680231, ECO:0000269|PubMed:25843888, ECO:0000269|PubMed:28507175}.

Source Description
UniProtINDUCTION: Repressed by brassinazole (BRZ), thus leading to a reduced number of stomata in hypocotyls (PubMed:25680231). Inhibited by low relative humidity (LRH) via epigenetic CG methylation, thus leading to a reduced stomatal index (PubMed:22442411). Repressed by YDA (at protein level) (PubMed:19008449). Post-transcriptional decrease of protein level in response to osmotic stress (e.g. mannitol), through the action of a mitogen-activated protein kinase (MAPK) cascade; this repression is reversed by the MAPK kinase inhibitor PD98059 (PubMed:25381317). {ECO:0000269|PubMed:19008449, ECO:0000269|PubMed:22442411, ECO:0000269|PubMed:25381317, ECO:0000269|PubMed:25680231}.
