ACH1 — Brassica napus

Summary

BnACH1 (ACH1) on chromosome A06 encodes a nitrate transporter belonging to the major facilitator superfamily (MFS), with nitrate and nitrite transmembrane transporter activity. In oilseed rape, it is associated with nitrate assimilation, transport, import, and cellular response to nitrate, as well as nitrogen utilization, glutamine metabolism, leaf senescence, root hair elongation, cell growth, ethylene anabolism, and syngamy. The transporter localizes to the plasma membrane, tonoplast, and membrane. Associations with agronomic traits include soluble protein and protein content, root volume, root length, root hair length, nitrate uptake, nitrogen uptake, cadmium uptake and accumulation, lateral root development, root elongation, flowering time, and pathogen resistance. Related genes in other species are linked to nitrate high-affinity transport, root development, and disease resistance.
