ACH1 — Brassica napus

Summary

BnACH1 (ACH1) on chromosome A08 of oilseed rape (Brassica napus) encodes a nitrate transporter of the MFS superfamily with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrogen utilization, nitrate assimilation, import and transport, as well as cellular response to nitrate, glutamine metabolism, ethylene anabolism, leaf senescence and development, root hair elongation, cell growth, syngamy and proteolysis. The product localizes to the plasma membrane, tonoplast and transporter complex. Associations with agronomic traits include soluble protein and protein content, root volume, root length and root hair length. Phenotypic connections link the gene to nitrate and nitrogen uptake, cadmium uptake and accumulation, lateral root initiation and development, root elongation, root hydraulic conductivity, flowering time, pathogen resistance, copper toxicity response and shoot-to-root ratio. Related genes in other species are linked to nitrate high-affinity transport, root development and disease resistance.
