NIR — Solanum tuberosum

Summary

PGSC0003DMG400025823 (NIR, StNIR) on potato chromosome 1 encodes a ferredoxin-nitrite reductase (EC 1.7.7.1) with 4Fe-4S cluster and heme binding, also annotated with sulfite reductase activity. The gene is associated with nitrate assimilation, nitrogen utilization, response to nitrate and iron, sulfate assimilation, sulfide oxidation, anammox, malate secretion, plastid DNA packaging, and alkaloid anabolism. It localizes to the chloroplast stroma and nucleoid, mitochondria, and apoplast. Associations include leaf chlorophyll and relative chlorophyll content, nitrogen content, nitrate transport, photosynthetic and respiration rates, stomatal resistance, protein content, drought tolerance, and salt tolerance. Related genes in other species are linked to nitrite reduction and acid rain resistance, leaf protein content, and disease susceptibility.
