Source Description
UniProtTranscription factor. {ECO:0000305}.
UniProtTranscription factor involved in the negative regulation of flavonol biosynthesis. Represses the early phenylpropanoid genes, phenylalanine ammonia-lyase (PAL), cinnamate 4-hydroxylase (C4H) and 4-coumarate-CoA ligase (4CL), as well as the flavonoid-specific genes, flavonoid 3'-hydroxylase (F3'H) and dihydroflavonol 4-reductase (DFR) (PubMed:24319076). Plays a role in seed germination inhibition. Negatively regulates the expression of the abscisic acid (ABA) signaling transcription factor ABI5 in seeds (PubMed:25053018). {ECO:0000269|PubMed:24319076, ECO:0000269|PubMed:25053018}.
