NHX1 — Capsicum annuum
Summary
CaNHX1 (T459_21189) on pepper chromosome 8 encodes a sodium/hydrogen exchanger 7, a member of the cation/H⁺ exchanger CPA1 family with lithium:proton antiporter, potassium:proton antiporter, sodium:hydrogen exchanger, sodium transporter, NAD ADP-ribosyltransferase, and protein kinase activities. The gene is associated with vacuolar membrane transport, sodium import, lithium export, potassium ion homeostasis, cell pH regulation, abscisic acid and nitric oxide anabolism, and response to superoxide. It localizes to the tonoplast, vacuole, endosome, plastid, and chloroplast envelope. CaNHX1 is associated with yield, sodium uptake, iron concentration, phosphorus uptake, photosynthetic rate, stomatal resistance, plant height, root development, high temperature stress response, disease tolerance, and salt tolerance. Related genes in other species link the family to vacuolar pH homeostasis, potassium accumulation, heat and cold tolerance, seed germination, and biomass production.
