GS1 — Triticum turgidum subsp. durum

Summary

TRITD4AV1G024730 (GS1) on durum wheat chromosome 4A encodes a protein with a Gln_synt_N domain and catalytic domain, and is annotated with glutamine synthetase activity and EC 6.3.1.2, as well as several other molecular functions including glutamate-tRNA ligase activity, histone acetyltransferase activity, and SUMO transferase activity. The gene is associated with nitrogen metabolism, the ammonia assimilation cycle, nitrate assimilation, glutamine synthesis, grain filling period, grain protein content, grain weight, grain size, leaf senescence, photosynthetic rate, starch grain synthesis, flowering time, abscisic acid sensitivity, and response to cadmium. The product is associated with localisation to the chloroplast thylakoid membrane, chloroplast envelope, chloroplast stroma, thylakoid, apoplast, plant-type cell wall, and plasmodesma. Related genes in other species are linked to grain nitrogen content, seedling vigour, flag leaf senescence, drought and salt stress tolerance, and lateral root development.
