ID 86229
Name ABA8ox1 (GENE SYMBOL)
Synonyms (2)
GRAMENE GENEGR:0101185
Type Gene
Species Oryza sativa (Oryza sativa) [ GR_tax:013681 ]
Germplasm
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.
