ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.3HG0283350 (HvACH1) on barley chromosome 3H 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 localizes to the plasmalemma, tonoplast, endomembrane system, and nucleus. HvACH1 is linked to nitrate influx, grain yield, photosynthetic rate, root and shoot dry weight, leaf weight, root length, and seed nitrate content. It has been connected to 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. Related genes in other species link the family to nitrate uptake capacity, root architecture, and nitrate transport from roots to shoots.
