Source Description
UniprotDEVELOPMENTAL STAGE: Expressed at the transition to terminal stomatal differentiation, just before and after the symmetric division of stomatal differentiation, being confined to late-stage guard mother cells (GMC) and to young, still differentiating guard cells (PubMed:16155180, PubMed:24571519). Detected in unopened flower buds, at the bases of sepals, petals, and stamens and in the receptacle of carpels, as well as both in style and stigma. Present at strong levels in the placenta within the ovary. Accumulates during ovule development in a dynamic pattern; first observed at high levels in the funiculus once integument outgrowth has begun and persists into later stages. Also expressed in the nucellus of younger ovules, especially in the megaspore mother cell (MMC) and in epidermal cells. Present in integuments, in the endothelial layer and the outer layer of the outer integument, which will form the mucilage-containing seed coat cells (PubMed:22915737). In developing embryos, first detected in cells in the ground tissue meristem at the early heart stage accumulates in the torpedo stage. In mature embryos, expressed in the embryonic hypocotyl and root tip. In seedlings, present first in the lower part of the hypocotyl and in the root tip, and later in petioles of cotyledons, young leaves, and lateral root primordia, near the pericycle. In young plants, strongly expressed in petioles of young leaves and cotyledons, especially in veins, in the basal part of young first leaves and cotyledons, and in root tips of lateral roots. Detected in the phloem, as well as in the cortex of inflorescence stems (PubMed:26391711). In roots, present in the root tip in columella cells, specifically in the lower tier of columella cells, as well as in developing metaxylem (PubMed:26391711, PubMed:26578169). Widely expressed in freshly emerged lateral roots. In elongating lateral roots, confined at high levels transiently in columella cells until differentiation (PubMed:26578169). Expressed at the base of developing flowers, including ovaries. In flowers, detected in ovaries, receptacles, and transiently, in anthers, and, later, in filaments. Also detected in the valve margins and receptacles of siliques and at the joint between the stigma and the style, as well as in the tapetum around pollen grains in maturing anthers (PubMed:26391711). {ECO:0000269|PubMed:16155180, ECO:0000269|PubMed:22915737, ECO:0000269|PubMed:24571519, ECO:0000269|PubMed:26391711, ECO:0000269|PubMed:26578169}.
UniprotTISSUE SPECIFICITY: Expressed in all shoot organs with higher levels in leaves, stems, flowers, siliques and floral buds. Also detected in roots tips. {ECO:0000269|PubMed:16155180, ECO:0000269|PubMed:26391711}.

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}.
