Encodes an oxidase involved in the catabolism of bioactive gibberellins.
overexpressor is late flowering under both SD and LD conditions. ( Plants are dwarfed and show pleiotropic defects. The flowering-time phenotype is stronger under SD conditions.) [Schomburg et al., 2003] Multiple mutant: ga2ox7;8
multiple mutant is early flowering under both SD and LD conditions. [Schomburg et al., 2003] Single mutant: ga2ox8
single mutant is early flowering under SD conditions only. [Schomburg et al., 2003] Function:
Catalyzes the 2-beta-hydroxylation of gibberellins (GA) precursors, rendering them unable to be converted to active GAs. Hydroxylates the C20-GA GA12 and GA53, but is not active on C19-GAs, like GA1, GA4, GA9 and GA20. [Data from UniProt]
