Protein function
Encodes an oxidase involved in the conversion of inactive gibberellins to their bioactive form.
Phenotype
Multiple mutant: ga20ox1;
ga20ox2 multiple mutant is late flowering under both SD and LD conditions.
[Rieu et al., 2008] Overexpressor: GA20OX2 overexpressor is early flowering under both SD and LD conditions.
[Coles et al., 1999] Single mutant: ga20ox2 single mutant is very slighlty late flowering under SD conditions only.
[Rieu et al., 2008] Function:Key oxidase enzyme in the biosynthesis of gibberellin that catalyzes the conversion of GA12 and GA53 to GA9 and GA20 respectively, via a three-step oxidation at C-20 of the GA skeleton. GA53 is less effectively oxidized than GA12, and GA25 is also formed as a minor product. Involved in the promotion of the floral transition, fertiliy and silique elongation, but plays only a minor role in elongation of seedling organs. Acts redundantly with GA20OX1.
