Gene : TT8 A. thaliana

DB identifier  ? AT4G09820 Secondary Identifier  ? locus:2118524
Name  ? TRANSPARENT TESTA 8 Brief Description  basic helix-loop-helix (bHLH) DNA-binding superfamily protein
TAIR Computational Description  basic helix-loop-helix (bHLH) DNA-binding superfamily protein;(source:Araport11)
TAIR Curator Summary  TT8 is a regulation factor that acts in a concerted action with TT1, PAP1 and TTG1 on the regulation of flavonoid pathways, namely proanthocyanidin and anthocyanin biosynthesis. Affects dihydroflavonol 4-reductase gene expression. It is thought that a ternary complex composed of TT2, TT8 and TTG1 is necessary for correct expression of BAN in seed endothelium. Also important for important for marginal trichome development. It binds the promoter of both AT3G26790 and AT1G28300.TT8 interacts with JAZ proteins to regulate anthocyanin accumulation. TT8 acts maternally to affect seed FA biosynthesis and inhibits seed FA accumulation by down-regulating a group of genes either critical to embryonic development or important in the FA biosynthesis pathway. TT8 represses the activities of LEAFY COTYLEDON1, LEAFY COTYLEDON2, and FUSCA3, the critical transcriptional factors important for seed development.
