ACH1 — Zea mays
Summary
ZmACH1 (also known as LIN1, NRT2, and several NRT2 family members) on maize chromosome 8 encodes a nitrate transporter of the MFS superfamily with nitrate and nitrite transmembrane transporter activity. The gene is associated with nitrate transport, nitrogen utilization, nitrate assimilation, and cellular response to nitrate, as well as starch metabolism, carotenoid anabolism, endosperm development, and seedling development. It localizes to the membrane, tonoplast, plasmalemma, cytoplasm, and nucleus. ZmACH1 has been linked to grain yield, nitrate content, seed protein content, carotenoid and lutein content, chlorophyll content, photosynthetic rate, leaf width, root length, lateral root length, and salt response. Studies of related genes in other species connect the family to nitrate uptake, root architecture, nitrogen remobilization, disease resistance, and biomass accumulation.
