GA2OX3 (TRAESCS1D02G400700) — triticum aestivum

Summary

TRAESCS1D02G400700, designated TaGA2ox or GA2OX3 on bread wheat chromosome 1D, encodes a protein with domains including Iron_ascorbate_oxido_reductase, DIOX_N, and Oxoglu/Fe-dep_dioxygenase_dom, and is annotated with gibberellin 2-oxidase activity, gibberellin 3-beta-dioxygenase activity, gibberellin 20-oxidase activity, flavanone 3-dioxygenase activity, dioxygenase activity, 2-oxoglutarate dioxygenase activity, vitamin C binding, redox activity, and metal binding. The gene is associated with gibberellin catabolism and metabolism, as well as with coumarin anabolism, phenylpropanoid anabolism, and flavonoid anabolism. It has been linked to plant height and grain yield, and to response to flooding, response to light stimulus, response to molecule of fungal origin, and defense response to oomycetes. The encoded protein localises to the cytosol and cytoplasm. Studies of related genes in other species connect the family to osmotic stress, stress tolerance, seed dormancy, and signalling involving abscisic acid, jasmonic acid and gibberellin.
