NHX1 — Solanum tuberosum
Summary
StNHX1 (PGSC0003DMG401021988) on potato chromosome 6 encodes a sodium/hydrogen exchanger belonging to the cation/H⁺ exchanger CPA1 family, with annotated lithium:proton and potassium:proton antiporter activities, sodium transporter activity, and additional annotations for NAD ADP-ribosyltransferase and protein kinase activities. The gene is associated with vacuolar membrane transport, sodium import and export, potassium ion homeostasis, cell pH regulation, and responses to copper and superoxide. It localizes to the tonoplast, vacuole, endosome, and chloroplast envelope. StNHX1 is associated with yield, plant height, root development, photosynthetic rate, stomatal resistance, disease tolerance, and responses to high temperature, UV-B, abscisic acid, and jasmonic acid. Related genes in other species are linked to sodium tolerance, potassium accumulation, vacuolar pH homeostasis, and heat and cold tolerance.
