ACH1 — Lactuca sativa

Summary

LsACH1 (ACH1) on chromosome 1 of garden lettuce encodes a protein with NO3_transporter and MFS domains, and is associated with nitrite transmembrane transporter activity and nitrate transmembrane transporter activity. The gene is associated with nitrate transmembrane transport, nitrite transport, nitrate import, nitrate assimilation, cellular response to nitrate, 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 linked to nitrate content, root hair length, root development, nitrogen transport and uptake, lateral root initiation and development, root elongation, root system architecture, cadmium uptake and accumulation, pathogen resistance, flowering time, growth promotion, copper toxicity response, root hydraulic conductivity, and fatty acid metabolism. Studies of related genes in other species connect the family to nitrate high-affinity transport, disease resistance, drought response, seed yield, biomass accumulation, and anthocyanin accumulation.
