Description |
| UniProt | Transcription activator (PubMed:24278028, PubMed:25268707). Binds to 5'-CAACTGTC-3' and/or 5'-TAACAAA-3' motif in target gene promoter (e.g. alpha-amylase) to promote their expression (PubMed:11743113). Positive regulator of abscisic acid (ABA) responses leading to growth arrest during seed germination (PubMed:17217461). Promotes the expression of aleurone-related genes (e.g. CP1, CP, GASA1, BXL1 and BXL2) in seeds. Together with MYB33 and MYB65, promotes the programmed cell death (PCD) leading to vacuolation of protein storage vacuoles (PSVs) in the aleurone layers during seed germination (PubMed:20699403). Maybe involved in the regulation of leaves lamina morphogenesis (PubMed:25268707). Involved in pollen grain development (PubMed:22101548). Together with MYB97 and MYB120, functions as a male factor that controls pollen tube-synergid interaction in fertilization. Required for pollen tube growth arrest and sperm cell release in the female gametophyte, probably via the regulation of pollen tube-specific gene expression (PubMed:24278028, PubMed:23791732). {ECO:0000269|PubMed:11743113, ECO:0000269|PubMed:17217461, ECO:0000269|PubMed:20699403, ECO:0000269|PubMed:22101548, ECO:0000269|PubMed:23791732, ECO:0000269|PubMed:24278028, ECO:0000269|PubMed:25268707}. |
| UniProt | Transcriptional activator of gibberellin-dependent alpha-amylase expression in aleurone cells. Involved in pollen and floral organs development. May bind to the 5'-TAACAAA-3' box of alpha-amylase promoter. {ECO:0000269|PubMed:9150608}. |
| UniProt | Transcriptional activator of gibberellin-dependent alpha-amylase expression in aleurone cells. Involved in pollen and floral organs development. May bind to the 5'-TAACAAA-3' box of alpha-amylase promoter. Required for anther development (PubMed:19454733, PubMed:20590996). Functions in parallel with UDT1 to regulate early anther development. Functions upstream of the transcription factor TDR and may positively regulate its transcription (PubMed:20590996). Required for pollen development. Probably required for controlling tapetal cell size and promoting tapetal programmed cell death (PCD) during anther development. Required for exine and Ubisch body formation in anthers. Interacts with the DNA specific motifs of giberrellin-up-regulated genes of anthers and regulates their expression. Positively regulates the expression of the laurate hydroxylase CYP703A3, known to be essential for the development of pollen exine and anther epicuticular layer (PubMed:19454733). Functions with MYBS1 to integrate diverse nutrient starvation and gibberellin (GA) signaling pathways during germination of grains. Sugar, nitrogen and phosphate starvation signals converge and interconnect with GA to promote the co-nuclear import of GAMYB and MYBS1, resulting in the expression of a large set of GA-inducible hydrolases, transporters and regulators that are essential for mobilization of nutrient reserves in the endosperm to support seedling growth (PubMed:22773748). {ECO:0000269|PubMed:14688295, ECO:0000269|PubMed:19454733, ECO:0000269|PubMed:20590996, ECO:0000269|PubMed:22773748}. |
