ACH1 — Brassica napus

Summary

BnACH1 (DARMORV10_C05P06220.1) on chromosome C05 of oilseed rape encodes a protein with a NO3_transporter domain and MFS superfamily domain, possessing both nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrogen utilization, nitrate assimilation, import and transport, as well as glutamine metabolism, ethylene anabolism, proteolysis, leaf senescence and development, root hair elongation, cell growth, and syngamy. The transporter localizes to the plasma membrane, tonoplast, and membrane transporter complexes. Associations include soluble protein and protein content, root volume, length and hair length, nitrate and cadmium uptake and accumulation, lateral root initiation and development, root elongation and hydraulic conductivity, flowering time, pathogen resistance, and copper toxicity response. Studies of related genes in other species link the family to nitrate high-affinity transport, root development, and disease resistance.
