D18 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.2HG0208900 (symbol D18, also known as HvD18 or HvGA4H) on barley chromosome 2H encodes a gibberellin 3-beta-dioxygenase, a member of the 2-oxoglutarate/Fe(II)-dependent dioxygenase superfamily. The gene is associated with plant height, coleoptile length, respiration rate, seed development, seed dormancy, and flowering time. It is linked to responses to red or far-red light, light stimulus, molecules of fungal origin, and gibberellin. The encoded protein localises to the cytoplasm. Studies of related genes in other species link the family to seed germination, gibberellin A1 biosynthesis, seed coat formation, dwarfism, and starch accumulation.
