GLU — Zea mays

Summary

ZM00001EB329710, designated ZmGLU (also known as GLU1, GLU2, FD-GOGAT, and GLS1) on maize chromosome 7, encodes a ferredoxin-dependent glutamate synthase (Fd-GOGAT) with glutamate synthase (ferredoxin) activity (EC 1.4.7.1). The gene is associated with numerous agronomic traits, including grain dry weight, grain moisture content, seed weight, biomass yield, harvest index, and grain filling period. It is linked to nitrogen content, nitrate transport, amino acid content, soluble protein content, and phosphorus concentration. ZmGLU has been connected to leaf thickness, canopy temperature, root architecture (root branching, lateral root number, root fresh and dry weight), stem diameter, and cell membrane stability. Associations also include responses to biotic and abiotic stress, leaf color, early leaf senescence, and regulation of photosynthesis and hormone metabolism. The protein localizes to chloroplast thylakoids, stroma, and envelope, as well as amyloplasts and stromules.
