GLN1.3 — Brassica napus

Summary

BnGLN1.3 (DARMORV10_A09P38590.1) on chromosome A09 encodes a glutamine synthetase, an enzyme with glutamine synthetase activity that also binds ATP and copper. This cytosolic protein is associated with nitrogen assimilation and metabolism, ammonium assimilation, glutamate metabolism, and proline metabolism. It is linked to nitrate assimilation, photorespiration, the glyoxylate cycle, and fatty acid and lipid oxidation. In terms of development, it is connected to anther development, microsporogenesis, sporopollenin biosynthesis, seed development, root development and senescence, and vegetative growth. The gene is also associated with drought tolerance and cytoplasmic male sterility. Studies of related genes in other species link the family to ammonium tolerance, lateral root development, and glutamine synthesis.
