cytochrome P450, family 707, subfamily A, polypeptide 2
Brief Description
cytochrome P450, family 707, subfamily A, polypeptide 2
TAIR Computational Description
cytochrome P450, family 707, subfamily A, polypeptide 2;(source:Araport11)
TAIR Curator Summary
Encodes a protein with ABA 8'-hydroxylase activity, involved in ABA catabolism. Member of the CYP707A gene family. This gene predominantly accumulates in dry seeds and is up-regulated immediately following imbibition. CYP707A2 appears to play a major role in the rapid decrease in ABA levels during early seed imbibition.
TAIR Short Description
cytochrome P450, family 707, subfamily A, polypeptide 2
Up-regulated from late-maturation to mature dry seed. Up-regulated immediately after seed imbibition, reaching a maximum at 6 hours and decreasing therafter.
Involved in the oxidative degradation of abscisic acid, but not in the isomerization of the produced 8'-hydroxyabscisic acid (8'-OH-ABA) to (-)-phaseic acid (PA). Involved in the control of seed dormancy and germination.
Mainly expressed in dry seeds. Lower expression in rosette leaves, flowers, siliques and stems. Not expressed in roots. Expressed in both endosperm and vascular tissues of embryo during the seed development and in cortex and endodermis in germinating embryo.
