ACH1 — Brachypodium distachyon

Summary

BdACH1 (BRADI_2G26210V3) on chromosome 2 of Brachypodium distachyon encodes a nitrate transporter belonging to the MFS superfamily with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate assimilation, cellular response to nitrate, and nitrate and nitrite transport, and its product localises to the membrane, tonoplast, plasmalemma, cytoplasm, nucleus, and transporter complex. BdACH1 has been linked to grain number, grain yield, photosynthetic rate, seed nitrate content, cadmium uptake and accumulation, nitrogen uptake and remobilisation, lateral root initiation and development, root elongation, root hair development, biomass production, flowering time, pathogen resistance, and copper toxicity response. Studies of related genes in other species connect the family to nitrate high-affinity transport, root architecture, and drought response, as well as nitrate transport from roots to shoots and yield.
