GE1 — Triticum aestivum

Summary

TaGE1 (TRAESCS2B02G201900) on wheat chromosome 2B encodes a cytochrome P450 monooxygenase of the CYP78A family, with oxidoreductase activity acting on paired donors and incorporating molecular oxygen. The gene is associated with regulation of growth rate, timing of organ formation, positive regulation of organ growth, seed growth, leaf formation, floral organ development, and auxin biosynthesis. It has been connected to grain yield, grain weight, embryo development, abiotic stress tolerance, leaf size, plastochron length, and organ size. The encoded protein localises to the endoplasmic reticulum and membrane. Studies of related genes in other species link the family to seed size, grain growth, shoot branching, leaf longevity, and drought tolerance.
