ACH1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.6HG0543380 (HvACH1) on barley chromosome 6H encodes a nitrate transporter belonging to the MFS superfamily with NO3_transporter and MFS_trans_sf domains, and exhibits both nitrate and nitrite transmembrane transporter activity. 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, membrane, cytoplasm, and nucleus. HvACH1 is linked to nitrate influx, grain yield, photosynthetic rate, root and shoot dry weight, leaf weight, root length, seed nitrate content, cadmium uptake and accumulation, pathogen resistance, lateral root initiation and development, root elongation, root hair development, flowering time, and biomass production. Studies of related genes in other species connect the family to nitrate transport, nitrogen remobilization, seed yield, drought response, and disease resistance.
