GLU (TRAESCS2D02G132900) — triticum aestivum

Summary

TRAESCS2D02G132900 (symbol GLU) on wheat chromosome 2D encodes a glutamate synthase (ferredoxin) enzyme (EC 1.4.7.1) that catalyses the conversion of glutamine and 2-oxoglutarate to two molecules of glutamate. The gene is associated with grain end-use quality, flour quality, gluten quality, grain protein concentration, and grain weight and yield. It is linked to photorespiration, ammonia assimilation, starch metabolism, endosperm development, and responses to sucrose and immune signals. The product localises to chloroplast stroma, thylakoid, amyloplast, and other compartments. Studies of related genes in other species link the family to glutamate biosynthesis, leaf senescence, and organ size, and to drought and salt stress responses and aluminium tolerance.
