GA2OX6 — triticum aestivum
Summary
TRAESCS6A02G221900 (symbol GA2OX6, also known as TaGA2ox and Rht24) on wheat chromosome 6A encodes a gibberellin 2beta-dioxygenase (EC 1.14.11.13), an enzyme with gibberellin 2-oxidase activity that belongs to the 2-oxoglutarate/Fe(II)-dependent dioxygenase family. The gene is associated with gibberellin catabolism and homeostasis, and has been linked to plant height, harvest index, grain weight, and grain yield. It is also associated with responses to flooding, defense against oomycetes, and salt stress tolerance. The encoded protein localizes to the cytoplasm and nucleus. Studies of related genes in other species link the family to dwarfism, root elongation under salt stress, seed dormancy, flowering time, and biomass accumulation.
