GA5 — Cucumis sativus

Summary

CsGA5 (CSA_6G075200) on cucumber chromosome 6 encodes a gibberellin 20-oxidase, a 2-oxoglutarate-dependent dioxygenase with vitamin C binding and metal binding activities. The gene is associated with gibberellin biosynthesis and content, plant height, stem elongation, flowering time, fruit set and fruit growth, parthenocarpy, seed germination, root development, and responses to flooding, red/far-red light, and short-day flowering. It has also been linked to chlorophyll content, abscission, cytokinin signaling, defense against oomycetes, and traits including fruit length and size, root number, trichome morphology, ethylene sensitivity, and disease tolerance. Studies of related genes in other species connect the family to gibberellin feedback regulation, meristem maintenance, stem growth, fruit development, parthenocarpic fruit-set, and salt tolerance.
