Transcription 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). Interacts with SAD2. Expressed in anthers (PubMed:24319076, PubMed:25053018). Expressed in pollen grains and mature seeds (PubMed:25053018). Expressed in roots and vasculature of leaves (PubMed:24319076). Induced by abscisic acid (ABA) and osmotic stress (PubMed:25053018). Induced by salt stress (PubMed:24319076, PubMed:25053018). No visible phenotype under normal growth conditions. Increased levels of flavonols (PubMed:24319076). Decreased levels of anthocyanins (PubMed:24319076, PubMed:25053018). Truncated N-terminus.
