20ox2 — Solanum tuberosum

Summary

PGSC0003DMG400039990 (symbol 20ox2, preferred name StGA20OX1) on potato chromosome 12 encodes a gibberellin 20-oxidase, a 2-oxoglutarate-dependent dioxygenase with annotated gibberellin 20-oxidase and 2-oxidase activities. The gene is associated with gibberellin biosynthesis, catabolism and homeostasis, as well as responses to flooding, light stimulus, fungal molecules, and oomycete defense. It is linked to seed germination, fruit ripening, ethylene sensitivity, stem elongation and stem length. The encoded protein localises to the cytoplasm and nucleus. Studies of related genes in other species connect the family to drought tolerance, chlorophyll content, root length, leaf shape, auxin content and fruit firmness.
