NHX1 — Cucumis sativus
Summary
CSA_7G393470 (NHX1) on cucumber chromosome 7 encodes a sodium/hydrogen exchanger belonging to the CPA1 family, with lithium:proton and potassium:proton antiporter activities. The gene is associated with vacuolar membrane transport, sodium import and export, potassium ion homeostasis, cell pH regulation, and responses to superoxide. It localizes to the tonoplast, vacuole, endosome, and plastid. NHX1 is associated with sodium exclusion, yield traits, root development, plant height, chlorophyll content, photosynthetic rate, stomatal resistance, and abiotic stress responses including high temperature and UV-B sensitivity. Associations also include auxin content, jasmonic acid sensitivity, and disease tolerance. Related genes in other species are linked to vacuolar pH regulation, potassium accumulation, heat and cold tolerance, seed germination, and biomass production.
