GLS1 — Phaseolus vulgaris

Summary

PHAVU_001G123900 (GLS1, PvGLS1) on French bean chromosome 1 encodes a protein with glutamate synthase activity, NADH-glutamate synthase activity, oxidoreductase activity, 3Fe-4S cluster binding, FAD binding, and FMN binding. The gene is associated with L-glutamate anabolism, the ammonia assimilation cycle, glycine metabolism, L-serine metabolism, photorespiration, and nitrogen assimilation. It has been linked to responses to light stimulus, cold, oxidative stress, sucrose, and brassinosteroid mediated signalling, as well as defense response and HR-PCD. Associations with agronomic traits include nitrate uptake, leaf composition trait, seedling growth and development trait, leaf senescence trait, stomatal complex closure time, and tolerance to salt, drought, cadmium, and oxidative stress. The product localises to chloroplast stroma, thylakoid, chloroplast envelope, stromule, amyloplast, and apoplast. Studies of related genes in other species link the family to iron homeostasis, chlorophyll biosynthesis, and transposable element silencing.
