NHX1 — Capsicum annuum
Summary
CaNHX1 (T459_24667) on pepper chromosome 10 encodes a sodium/hydrogen exchanger 4, a member of the CPA1 cation/H+ exchanger family with lithium:proton antiporter, potassium:proton antiporter, sodium:hydrogen exchanger and sodium transporter activities. The gene is associated with vacuolar membrane transport, sodium import, lithium export, potassium ion homeostasis, cell pH regulation, and abscisic acid and nitric oxide anabolism. It localises to the tonoplast, vacuolar membrane, endosome and plastid. CaNHX1 is associated with yield, photosynthetic rate, stomatal resistance, plant height, root development, disease tolerance, and responses to high temperature, UV-B, salt and abiotic stress. Related genes in other species link it to sodium tolerance, potassium accumulation, vacuolar pH homeostasis, heat and cold tolerance, seed germination, biomass production and ion transport.
