GA5 — Cucumis sativus

Summary

CsGA5 (CSA_3G179110) in cucumber encodes a gibberellin 20-oxidase, a 2-oxoglutarate-dependent dioxygenase with leucocyanidin oxygenase activity, and is associated with gibberellin biosynthesis and signaling. The gene is linked to regulation of growth, plant height, stem internode number, leaf size, root growth, fruit length and size, fruit set, parthenocarpy, and biomass. It has been connected to flowering time, floral transition, seed germination, chlorophyll content, stomatal resistance, ethylene sensitivity, and responses to flooding, red or far red light, and short-day conditions. Associations also include abscission, abscisic acid and anthocyanin anabolism, downregulation of chlorophyll anabolism, and tolerance to salt stress and wind. The protein localizes to the cytoplasm. Studies of related genes in other species link the family to gibberellin metabolism, stem and hypocotyl elongation, fruit development, trichome formation, and salt tolerance.
