ACH1 — Lactuca sativa

Summary

LsACH1 (also known as NRT2.1, NRT2.2, NRT2.3, NRT2.4, LIN1) on chromosome 7 encodes a nitrate transporter belonging to the major facilitator superfamily (MFS) with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transmembrane transport, nitrate import, nitrite transport, nitrate assimilation, cellular response to nitrate, pH reduction, cell development, cell wall organization, terpenoid anabolism, triglyceride metabolism, and response to wounding. The product localizes to the plasma membrane, tonoplast, and transporter complex. LsACH1 is associated with nitrate content, root hair length, root development, lateral root initiation, nitrogen uptake and transport, cadmium uptake and accumulation, pathogen resistance, flowering time, root hydraulic conductivity, and fatty acid metabolism. Studies of related genes in other species connect the family to acyl-CoA thioesterase activity, nitrate high-affinity transport, disease resistance, drought response, seed yield, and biomass accumulation.
