ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0543580 (HvACH1) on barley chromosome 6H encodes a nitrate transporter with nitrate and nitrite transmembrane transporter activity, belonging to the MFS superfamily and NO3_transporter family. The gene is associated with nitrate transmembrane transport, nitrate import, nitrate assimilation, cellular response to nitrate, and response to wounding. It localises to the plasma membrane, tonoplast, endomembrane system, transporter complex, cytoplasm, and nucleus. HvACH1 is associated with nitrate influx, grain yield, photosynthetic rate, shoot and root dry weight, leaf weight, root length, and seed nitrate content. Additional associations include cadmium uptake and accumulation, pathogen resistance, lateral root initiation and development, root elongation, root hair development, flowering time, biomass production, nitrogen uptake efficiency, and adaptation to nitrogen starvation. Studies of related genes in other species connect the family to nitrate transport, root-to-shoot nitrate movement, disease resistance, and seed yield.
