ACH1 — Brachypodium distachyon

Summary

BdACH1 (BRADI_3G01277V3) encodes a nitrate transporter of the MFS superfamily with nitrate and nitrite transmembrane transporter activity, localised to the plasma membrane, tonoplast, and endomembrane system. It is associated with nitrate assimilation, transport, and cellular response to nitrate, as well as response to wounding. The gene has been linked to grain number, grain yield, photosynthetic rate, seed nitrate content, cadmium uptake and accumulation, lateral root initiation and development, root elongation, root hair development, pathogen resistance, nitrogen uptake and remobilization, biomass production, and flowering time. Studies of related genes in other species connect the family to additional traits including seed protein content, carotenoid content, drought response, and disease resistance, though these associations are not yet established in Brachypodium.
