Regulatory interactions between TGA and ATHB1 in abscisic acid biosynthesis. The three abscisic acid metabolic pathways are regulated differently by both TGA1 and ATHB1, The two TFs reciprocally regulate CYP707A1 (AT4G19230, an abscisic acid 8’-hydroxylase) gene in phaseic acid biosynthesis pathway. The regulation of ATHB1 on three pathways cooperates with its negative regulation on TGA1’s expression.
