UniprotTISSUE SPECIFICITY: Expressed specifically in guard cells (PubMed:16005292). Expressed in sink tissues, such as xylem, roots and developing seeds (PubMed:22708996). {ECO:0000269|PubMed:16005292, ECO:0000269|PubMed:22708996}.
Functional Description ? help Back to Top
Source Description
TAIREncodes putative transcription factor. Mutants lack of mucilage extrusion from the seeds during imbibition. Reduced quantities of mucilage are deposited during the development of the seed coat epidermis in myb61 mutants. Expressed in guard cells,loss of function mutations show an increase in stomatal pore opening suggesting a role in ABA independent regulation of stomatal pore size.
UniProtTranscription 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}.
