NR — Glycine max

Summary

GmNR (GLYMA_14G165000V4) encodes a nitrate reductase (NADPH) enzyme, possessing NADH:nitrate reductase activity, cytochrome-b5 reductase activity, sulfite oxidase activity, and cytokinin riboside 5'-monophosphate phosphoribohydrolase activity, along with FAD, molybdenum cofactor, and heme binding domains. This soybean gene on chromosome 14 is associated with the regulation of nitrate assimilation, cellular responses to nitrogen and potassium starvation, nitric oxide and cytokinin anabolism, sulfur metabolism, stomatal complex patterning, and pollen-pistil interaction. It has been linked to numerous agronomic traits including nitrate sensitivity and transport, nitrogen use efficiency, seed size, oleic acid content, leaf length, whole plant size, shoot branching, adventitious root number, and responses to aluminum, copper, osmotic stress, UV-B light, herbicides, viral disease, and powdery mildew. Studies of related genes in other species connect the family to stomatal function, freezing tolerance, pathogen resistance, and biomass accumulation.
