NHX1 — Cucumis melo
Summary
MELO3C015897.2, designated CmNHX1 on melon chromosome 2, encodes a member of the cation/H⁺ exchanger CPA1 family with sodium:hydrogen exchanger, lithium:proton antiporter and potassium:proton antiporter activities. The product localises to the tonoplast, vacuole, endosome and plastid. CmNHX1 is associated with vacuolar membrane transport, sodium and potassium ion membrane transport, cell pH regulation, potassium ion homeostasis, response to superoxide, nitric oxide anabolism, lateral root morphogenesis and protein sorting. It has been linked to yield, plant height, root development, seedling growth, photosynthetic rate, stomatal resistance, abscisic acid sensitivity, disease tolerance, and responses to high temperature, UV-B and abiotic stress. Associations also include sodium uptake, iron concentration, phosphorus uptake, auxin content and jasmonic acid sensitivity.
