ACH1 — Lactuca sativa

Summary

LsACH1, also known as LsNRT2, encodes a protein belonging to the NO3_transporter and 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, and cellular response to nitrate. It is also linked to triglyceride metabolism, terpenoid anabolism, cell wall organization, response to wounding, and pH reduction. Associations include nitrate content, root hair length, root development, lateral root initiation, root elongation, flowering time, cadmium uptake and accumulation, pathogen resistance, and growth promotion. The encoded protein localizes to the plasma membrane, tonoplast, and transporter complex. Studies of related genes in other species link the family to high-affinity nitrate transport, nitrate remobilization, seed yield, drought response, and disease resistance.
