Protein function

Encodes an oxidase involved in the catabolism of bioactive gibberellins.

Phenotype

Single mutant:
ga2ox6 single mutant does not display any flowering-time phenotype. [Rieu et al., 2008]

Multiple mutant:
The quintuple ga2ox mutant (i.e. ga2ox1;2;3;4;6)) is early flowering under both SD and LD conditions. ( The flowering-time phenotype much stronger under SD conditions.) [Rieu et al., 2008]

Multiple mutant:
ga2ox2;6 and ga2ox2;4;6 multiple mutants are early flowering under SD conditions. ( No data available under LD conditions.) [Rieu et al., 2008]

Function:
Catalyzes the 2-beta-hydroxylation of several biologically active gibberellins, leading to the homeostatic regulation of their endogenous level. Catabolism of gibberellins (GAs) plays a central role in plant development. Converts GA9/GA20 to GA51/GA29 and GA4/GA1 to GA34/GA8. Has no C20-GA 2 oxidase activity against GA12 and GA53.
