NR — Glycine max

Summary

GmNR (GLYMA_14G164900V4) encodes a protein with nitrate reductase (NADPH) activity, NADH:nitrate reductase activity, cytochrome-b5 reductase activity, sulfite oxidase activity, and cytokinin riboside 5'-monophosphate phosphoribohydrolase activity, along with molybdenum cofactor and FAD binding. In soybean, this gene is associated with regulation of nitrate assimilation, cellular responses to nitrogen and potassium starvation, nitric oxide and cytokinin anabolism, sulfur metabolism, and stomatal complex patterning. It is linked to traits including nitrate sensitivity and transport, phosphorus response, oleic acid content, seed coat morphology, adventitious root number, aluminum response, and whole plant size. Associations also include cytokinin production, nitrogen use efficiency, freezing tolerance, stomatal function, and disease susceptibility. Related genes in other species are linked to nitrate reduction, nitric oxide generation, lateral root development, and stress responses including salt and herbicide resistance.
