Protein

Gibberellin 20 oxidase 2

Gene

20ox2

Organism
Oryza sativa subsp. indica (Rice)
Status
Reviewed-Annotation score: Annotation score: 4 out of 5-Experimental evidence at protein leveli

Functioni

Key oxidase enzyme in the biosynthesis of gibberellin that catalyzes the conversion of GA53 to GA20 via a three-step oxidation at C-20 of the GA skeleton.1 Publication

Miscellaneous

A second gene, 20ox1, is preferentially expressed in the reproductive organs and enables the flowers in sd1 plants to develop and be fertilized normally.

Cofactori

Protein has several cofactor binding sites:

Pathology & Biotechi

Biotechnological usei

This gene, also known as the 'green revolution gene' has been introduced by conventional breeding procedures into several cultivars. It provides rice cultivars with short, thick culms, raises the harvest index, improves lodging resistance and responsiveness to nitrogen fertilizer, resulting high yields without affecting panicle and grain quality.
