ACH1 — Brassica napus

Summary

BnACH1, located on chromosome A09 of oilseed rape (Brassica napus), encodes a nitrate transporter belonging to the NO3_transporter and major facilitator superfamily (MFS). The gene product possesses nitrate and nitrite transmembrane transporter activity and is associated with nitrate import, assimilation, and transport, as well as nitrogen utilization, cellular response to nitrate, and glutamine metabolism. It has been linked to root hair elongation, leaf development and senescence, cell growth, ethylene anabolism, and syngamy. The transporter localizes to the plasma membrane, tonoplast, and membrane transporter complexes. Associations with agronomically relevant traits include root volume, root length, root hair length, soluble protein content, and protein content. Related genes in other species have been linked to nitrate uptake, root development, flowering time, and disease resistance.
