ACH1 — Brassica napus

Summary

BnACH1 (ACH1) on chromosome A06 of oilseed rape (Brassica napus) encodes a nitrate transporter belonging to the NO3_transporter and major facilitator superfamily (MFS), with both nitrate and nitrite transmembrane transporter activities. The gene is associated with nitrate transport, import, assimilation, and cellular response to nitrate, as well as nitrogen utilization, glutamine metabolism, and ethylene anabolism. It is linked to root and leaf development, leaf senescence, root hair elongation, cell growth, and syngamy. The encoded protein localizes to the plasma membrane, tonoplast, and transporter complexes. Associations with traits include soluble protein and protein content, root volume, root length, root hair length, pathogen resistance, cadmium uptake and accumulation, flowering time, lateral root development, root hydraulic conductivity, and shoot-to-root ratio. Related genes in other species link the family to nitrate high-affinity transport, root development, and disease resistance.
