GT1 — Zea mays

Summary

ZM00001EB128410 (ZmGT1, GT1) on maize chromosome 3 encodes a protein with transglycosidase activity, belonging to the Glyco_trans_1 and Glyco_trans_4_5 families. The gene is associated with sex determination, meristem determinacy, carpel development, shade avoidance, detoxification, anthocyanin anabolism, nitric oxide storage, programmed cell death, and secondary metabolite biosynthesis. It is linked to inflorescence branching, flavonoid content, ear number, tiller number, and grain traits, as well as decreased sensitivity to cold and oxidative stress. The product localises to the trans-Golgi network, endosome, and Golgi complex. Studies of related genes in other species connect the family to spikelet number, grain number, growth, stress responses, pollen development, and reproductive traits.
