NHX1 — Cucumis melo
Summary
MELO3C026096.2, designated CmNHX1 on melon chromosome 13, encodes a sodium/hydrogen exchanger belonging to the NaH_exchanger and cation/H_exchanger_CPA1 families. The product exhibits lithium:proton and potassium:proton antiporter activity, sodium transporter activity, and is annotated with protein kinase and NAD ADP-ribosyltransferase activities. CmNHX1 is associated with vacuolar membrane transport, sodium and potassium ion homeostasis, cell pH regulation, and response to superoxide. It localizes to the tonoplast, vacuole, endosome, and chloroplast envelope. The gene is associated with yield, photosynthetic rate, stomatal resistance, plant height, root development, and abiotic stress responses including high temperature and salinity. Studies of related genes in other species connect the family to vacuolar pH regulation, sodium accumulation, potassium uptake, heat and cold tolerance, and biomass production.
