Description |
| TAIR | Encodes a putative transcription factor (MYB55). |
| UniProt | Transcription factor that coordinates a small network of downstream target genes required for several aspects of plant growth and development, such as xylem formation and xylem cell differentiation, and lateral root formation (PubMed:22708996). Regulates a specific set of target genes by binding DNA to the AC cis-element 5'-ACCTAC-3' (PubMed:23741471). Functions as a transcriptional regulator of stomatal closure. Plays a role the regulation of stomatal pore size independently of abscisic acid (ABA) (PubMed:16005292). Required for seed coat mucilage deposition during the development of the seed coat epidermis (PubMed:19401413). Involved in the induction of trichome initiation and branching by positively regulating GL1 and GL2. Required for gibberellin (GA) biosynthesis and degradation by positively affecting the expression of the enzymes that convert GA9 into the bioactive GA4, as well as the enzymes involved in the degradation of GA4 (PubMed:28207974). {ECO:0000269|PubMed:16005292, ECO:0000269|PubMed:19401413, ECO:0000269|PubMed:22708996, ECO:0000269|PubMed:23741471, ECO:0000269|PubMed:28207974}. |
