1 We have previously identified that four members of the Arabidopsis (Arabidopsis thaliana) CYP707A gene family (CYP707A1 to CYP707A4) encode ABA 8"-hydroxylases, and that the cyp707a2 mutants showed an increase in ABA levels in dry and imbibed seeds. Abscisic Acid cytochrome P450, family 707, subfamily A, polypeptide 2 Arabidopsis thaliana

3 On the other hand, CYP707A2 is responsible for the regulation of ABA levels from late-maturation to germination. Abscisic Acid cytochrome P450, family 707, subfamily A, polypeptide 2 Arabidopsis thaliana
