20ox2 — Medicago truncatula

Summary

MTR_3G096500 (symbol 20ox2, preferred name MtGA20OX5) encodes a protein with a DIOX_N domain and an IPNS-like Fe2OG oxygenase domain, and is annotated with gibberellin 20-oxidase activity, (S)-tetrahydroprotoberberine N-methyltransferase activity, flavanone 3-dioxygenase activity, dioxygenase activity, 2-oxoglutarate dioxygenase activity, vitamin C binding, and metal binding. In barrel medic, this gene is associated with gibberellin biosynthesis and metabolism, as well as responses to flooding, salt stress, light stimulus, and oomycete defense. It has been linked to somatic embryogenesis, seed germination, leaf development, and regulation of growth. Associations with biomass yield, stem elongation, leaf size, plant height, and seed dormancy have been noted. The encoded protein is predicted to localize to the cytoplasm. Studies of related genes in other species connect the family to additional dioxygenase activities.
