ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0543510 (HvACH1) 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 import, nitrate assimilation, and cellular response to nitrate, as well as response to wounding. It localizes to the plasma membrane, tonoplast, endomembrane system, and transporter complex. HvACH1 is linked to nitrate influx, and associations include grain yield, photosynthetic rate, root and shoot dry weight, leaf weight, root length, seed nitrate content, cadmium uptake and accumulation, pathogen resistance, lateral root development, root hair development, flowering time, and nitrogen uptake efficiency. Studies of related genes in other species connect the family to nitrate transport, root architecture, biomass accumulation, disease resistance, and nitrogen remobilization.
