NR — Cicer arietinum

Summary

LOC101498580 (CaNR) on chickpea chromosome 2 encodes a protein with nitrate reductase (NADPH) activity, and is also annotated with cytokinin riboside 5'-monophosphate phosphoribohydrolase, cytochrome-b5 reductase, sulfite oxidase, and NADH:nitrate reductase activities, and binds molybdenum cofactor, FAD, and SUMO. The gene is associated with regulation of nitrate assimilation, nitric oxide and cytokinin anabolism, sulfur metabolism, cellular responses to nitrogen and potassium starvation, post-embryonic root development, stomatal complex patterning, and downregulation of systemic acquired resistance. It is linked to traits including nitrate sensitivity and transport, phosphorus response, seed coat morphology, leaf length, oleic acid content, adventitious root number, and cytokinin content. Related genes in other species are associated with nitrate reduction, nitric oxide generation, lateral root development, stomatal function, freezing tolerance, pathogen resistance, and biomass accumulation.
