ACH1 — Lactuca sativa

Summary

LsACH1, also known as LsNRT2, encodes a protein with a NO3_transporter domain and MFS domain, and has nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transport, import, assimilation, and cellular response to nitrate, as well as pH reduction, cell development, cell wall organization, wounding response, triglyceride metabolism, and terpenoid anabolism. It localizes to the plasma membrane, tonoplast, and transporter complexes. LsACH1 is linked to nitrate content, root hair length, root development, nitrogen uptake and transport, lateral root initiation, cadmium uptake and accumulation, pathogen resistance, flowering time, and root system architecture. Studies of related genes in other species associate the family with nitrate high-affinity transport, nitrate acquisition, drought response, disease resistance, seed yield, and biomass accumulation.
