ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0543590 (HvACH1) on barley chromosome 6H encodes a nitrate transporter belonging to the NO3_transporter and MFS superfamilies, with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transmembrane transport, nitrate import, nitrite transport, nitrate assimilation, and cellular response to nitrate, as well as 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, root and shoot dry weight, leaf weight, root length, and seed nitrate content. Associations also include cadmium uptake and accumulation, lateral root initiation and development, root elongation, pathogen resistance, flowering time, and biomass production. Studies of related genes in other species connect the family to nitrate acquisition, nitrogen remobilisation, root architecture, and disease resistance.
