NIR — Capsicum annuum

Summary

CaNIR (T459_33018) on pepper chromosome PGAv.1.6.scaffold1041 encodes a ferredoxin-nitrite reductase with NO-forming nitrite reductase and sulfite reductase (ferredoxin) activities, binding 4Fe-4S clusters and heme. The gene is associated with nitrate assimilation and response, sulfate assimilation, sulfide oxidation, sulfur metabolism, lignin anabolism, cadmium transport, plastid DNA packaging, and syngamy. Its product localizes to the chloroplast nucleoid, stroma, apoplast, mitochondria, and the sulfite reductase complex. CaNIR is linked to root nitrogen content, plant dry weight, leaf water potential, amino acid, sugar, protein, and lignin content, photosynthetic and respiration rates, and drought tolerance. Related genes in other species are linked to nitrite reduction, acid rain resistance, and nitrogen utilization.
