ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0543390 (symbol ACH1, also known as BCH3, 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 assimilation, import, and transport, as well as cellular response to nitrate and response to wounding. It localises to the plasma membrane, tonoplast, and endomembrane system. Associations include grain yield, shoot and root dry weight, leaf weight, root length, photosynthetic rate, and seed nitrate content. The gene has been linked to nitrate and cadmium uptake, lateral root initiation and development, root elongation, pathogen resistance, nitrogen uptake efficiency, biomass production, and flowering time. Related genes in other species link the family to nitrate high-affinity transport, root development, and disease resistance.
