Source Description
UniProtTranscription factor that binds to DNA in promoters cis-regulatory element 5'-GGCGCGC-3' of cell cycle genes, including cyclins, cyclin-dependent kinases (CDKs), and components of the pre-replication complex (PubMed:20675570, PubMed:24687979). Binds to DNA in promoters cis-regulatory element 5'-AGCCG-3' of auxin regulated genes (e.g. PIN3 and PIN7) (PubMed:26578169). Together with FAMA and MYB88, ensures that stomata contain just two guard cells (GCs) by enforcing a single symmetric precursor cell division before stomatal maturity (PubMed:24571519). Represses the expression of the mitosis-inducing factors CDKB1-1 and CDKA-1, specifically required for the last guard mother cells (GMC) symmetric divisions in the stomatal pathway (PubMed:20675570, PubMed:24687979). Represses CYCA2-3 in newly formed guard cells (PubMed:21772250). Together with MYB88, regulates stomata spacing by restricting divisions late in the stomatal cell lineage thus limiting the number of GMC divisions (PubMed:11536724, PubMed:9684356, PubMed:16155180, PubMed:24123248). In collaboration with CDKB1-1 and CDKB1-2, restrict the G1/S transition and chloroplast and nuclear number during stomatal formation, and normally maintain fate and developmental progression throughout the stomatal cell lineage (PubMed:24123248). Also involved in the shape regulation of pavement cells (PubMed:9684356). Involved in sensing and/or transducing abiotic stress (e.g. drought and salt), probably via the positive regulation of NAC019 (PubMed:21105921). Regulates female reproduction being required for entry into megasporogenesis, probably via the regulation of cell cycle genes (PubMed:22915737). Promotes histone H3K27me3 marks and represses stem cell gene expression (PubMed:24654956). Required for lateral roots (LRs) initiation via the regulation of PIN3 expression in an auxin-dependent manner (PubMed:26578065). Involved in responses to gravity stimulation in primary roots by regulating the transcription of PIN3 and PIN7 in gravity-sensing cells, thus modulating auxin asymmetric redistribution (PubMed:26578169). {ECO:0000269|PubMed:11536724, ECO:0000269|PubMed:16155180, ECO:0000269|PubMed:20675570, ECO:0000269|PubMed:21105921, ECO:0000269|PubMed:21772250, ECO:0000269|PubMed:22915737, ECO:0000269|PubMed:24123248, ECO:0000269|PubMed:24571519, ECO:0000269|PubMed:24654956, ECO:0000269|PubMed:24687979, ECO:0000269|PubMed:26578065, ECO:0000269|PubMed:26578169, ECO:0000269|PubMed:9684356}.
