NHX1 — Solanum tuberosum
Summary
StNHX1 (PGSC0003DMG400022786) on potato chromosome 1 encodes a cation/H+ exchanger of the CPA1 family with sodium:hydrogen exchanger, lithium:proton antiporter and potassium:proton antiporter activities. The product localises to the tonoplast, vacuolar membrane, endosome and plastid, and is associated with vacuolar membrane transport, sodium and potassium ion import and homeostasis, cell pH regulation, response to copper and superoxide, and nitric oxide anabolism. StNHX1 is linked to yield, plant height, root development, photosynthetic rate, stomatal resistance, and responses to high temperature, UV-B, salinity, drought, abscisic acid and jasmonic acid. It has also been connected to iron and phosphorus uptake, auxin content, meristem identity, cell cycle traits, and disease tolerance. Related genes in other species link the family to vacuolar pH regulation, potassium accumulation, heat and cold tolerance, seed germination, and biomass production.
