ACH1 — Medicago truncatula

Summary

MTR_4G057865 (MtACH1) on barrel medic chromosome 4 encodes a nitrate transporter family protein with a major facilitator superfamily (MFS) domain, possessing both nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transport, assimilation, import, and cellular response to nitrate, as well as nitrogen fixation, nodulation, root system development, and response to wounding. It localizes to the plasma membrane, tonoplast, and transporter complex. MtACH1 is associated with nitrate uptake, lateral root initiation and development, root elongation, root hair development, root system architecture, flowering time, plant growth, cadmium uptake and accumulation, pathogen resistance, copper toxicity response, and fatty acid and amino acid metabolism. Studies of related genes in other species connect the family to nitrate high-affinity transport, root and shoot development, disease resistance, and seed yield.
