ACH1 — Brachypodium distachyon

Summary

BdACH1 (BRADI_3G01290V3) on chromosome 3 of Brachypodium distachyon encodes a protein of the NO3_transporter family and MFS superfamily with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate assimilation, cellular response to nitrate, and response to wounding. Its product localizes to the plasma membrane, tonoplast, and transporter complex. BdACH1 is associated with grain number, grain yield, and photosynthetic rate, as well as with nitrate uptake, nitrogen uptake efficiency, and cadmium accumulation. It is linked to lateral root initiation, root elongation, root hair development, and biomass production. Studies of related genes in other species link the family to nitrate transport from roots to shoots, seed yield, disease resistance, and drought response.
