| Description | The gene encodes for an enzyme ABA 8'-hydroxylase that catalyses the oxidation of plant hormone abscisic acid (ABA) to phaseic acid (PA), thsu playing a role in the ABA catabolism.Its mRNA expression increased within 1h after submergence with a simultaneous decrease in ABA levels in submerged rice shoots, that is controlled partly by ethylene-induced expression of ABA8ox1 and partly by ethylene-independent suppression of genes involved in the biosynthesis of ABA e.g. Zeaxanthin epoxidase (ZEP) and Epoxycarotenoid dioxygenase (NCED). The protein is localized in the endoplasmic reticulum. |
