ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0543400 (symbol ACH1, also known as BCH1, NRT2, and LIN1) on barley chromosome 6H encodes a nitrate transporter belonging to the MFS superfamily with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transmembrane transport, nitrate assimilation, cellular response to nitrate, pH reduction, and response to wounding. Its product localises to the plasma membrane, tonoplast, and endomembrane system. ACH1 has been linked to grain yield, photosynthetic rate, root and shoot dry weight, leaf weight, root length, seed nitrate content, cadmium uptake and accumulation, lateral root initiation and development, root hair development, pathogen resistance, nitrogen uptake efficiency, and biomass production. Studies of related genes in other species connect the family to nitrate high-affinity transport, root architecture, and drought response.
