NHX1 — Cucumis melo
Summary
MELO3C015375.2, also known as CmNHX1, encodes a sodium/hydrogen exchanger belonging to the CPA1 family of cation/H+ exchangers. The protein exhibits lithium:proton antiporter, potassium:proton antiporter, and sodium transporter activities. In melon, CmNHX1 is associated with vacuolar membrane transport, sodium and potassium ion membrane transport, cell pH regulation, and response to superoxide. It localizes to the tonoplast, vacuole, endosome, and plastid. The gene is associated with yield, plant height, root development, photosynthetic rate, stomatal resistance, and responses to abiotic stresses including high temperature stress response and UV-B light sensitivity. Associations also include iron concentration, phosphorus uptake, auxin content, jasmonic acid sensitivity, and disease tolerance. Studies of related genes in other species connect this gene family to ion homeostasis, vacuolar pH regulation, salt tolerance, and plant growth and development.
