ACH1 — Lactuca sativa

Summary

LsACH1 (ACH1) on lettuce chromosome 1 encodes a protein with a NO3_transporter domain and a major facilitator superfamily (MFS) domain, and is annotated 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, response to wounding, triglyceride metabolism, and terpenoid anabolism. 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, cadmium uptake and accumulation, pathogen resistance, flowering time, growth promotion, and root hydraulic conductivity. Studies of related genes in other species associate the family with high-affinity nitrate transport, nitrate remobilization, drought response, disease resistance, seed yield, and biomass accumulation.
