GA2OX3 (TRAESCS3A02G133400) — triticum aestivum

Summary

TRAESCS3A02G133400, also known as GA2OX3 or TaGA2ox, encodes a protein with gibberellin 2-oxidase activity on wheat chromosome 3A, a member of the 2-oxoglutarate-dependent dioxygenase family. The gene is associated with gibberellin catabolism, gibberellin metabolism, and gibberellin biosynthesis, as well as regulation of growth, leaf senescence, flower development, and defense response. It has been linked to chlorophyll content in wheat and to grain width, grain weight, and sugar content. Studies of related genes in other species connect the family to mesocotyl length, seed viability, seed growth, and grain yield, while maize GA2OX2 has been associated with seed germination. The gene also shows connections to ethylene sensitivity and response to light stimulus.
