GLU — Triticum turgidum subsp. durum

Summary

TRITD2BV1G047890, designated GLU in durum wheat and located on chromosome 2B, encodes a ferredoxin-dependent glutamate synthase (Fd-GOGAT), an enzyme with glutamate synthase activity (EC 1.4.7.1) that catalyses the conversion of L-glutamine to L-glutamate. This gene is associated with nitrogen assimilation, photorespiration, and ammonium assimilation, as well as responses to ammonia, sucrose, cold, and light stimulus. It has been linked to grain filling period, grain protein content, photosynthetic rate, leaf senescence, and seedling growth and development traits. Associations also include drought resistance, salt tolerance, cadmium tolerance, oxidative stress response, and biotic and abiotic stress response traits. The product localises to chloroplast stroma, thylakoid, amyloplast, and other cellular compartments. Studies of related genes in other species link the family to glutamate biosynthesis, organ size, and transposable element silencing.
