GA5 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.5HG0536610 (HvGA5) on barley chromosome 5H encodes a gibberellin 20-oxidase, a 2-oxoglutarate-dependent dioxygenase with iron/ascorbate oxidoreductase and DIOX_N domains. The enzyme is associated with gibberellin signaling and response, regulation of growth, leaf and flower development, cell cycle, and polar cell growth. It has been linked to responses to flooding, red/far-red light, short-day flowering, light stimulus, oomycete defense, and flavonoid anabolism. The gene is associated with plant height, grain weight, harvest index, anthesis time, starch and protein content, respiration rate, and grain yield. It has also been connected to seed germination, root growth, biomass, stem internode number, and tolerance to salt, chilling, and wind. The protein localizes to the cytoplasm and nucleus.
