ACH1 — Lactuca sativa

Summary

LsACH1 (also known as LsNRT2) on chromosome 6 encodes a nitrate transporter belonging to the major facilitator superfamily (MFS) with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transport, import, assimilation, and cellular response to nitrate, as well as nitrite transport, pH reduction, cell development, cell wall organization, terpenoid anabolism, triglyceride metabolism, and response to wounding. It localizes to the plasma membrane, tonoplast, and transporter complex. LsACH1 is associated with nitrate content, root hair length, root development, nitrogen uptake and transport, lateral root initiation, cadmium uptake and accumulation, flowering time, pathogen resistance, growth promotion, root elongation, and root hydraulic conductivity. Studies of related genes in other species connect the family to additional traits including biomass yield, seed yield, drought tolerance, disease tolerance, plant height, and anthocyanin content.
