NHX8 — Triticum aestivum
Summary
TRAESCS2D02G135600 (TaNHX8) on wheat chromosome 2D encodes a cation/H⁺ exchanger of the CPA1 family with lithium:proton antiporter, sodium:hydrogen exchanger, and potassium:proton antiporter activities. It is associated with salt stress tolerance, sodium uptake and efflux, lithium transport and homeostasis, potassium acquisition, and cell pH regulation. The gene has been linked to yield, plant height, root development, leaf chlorophyll content, photosynthetic rate, stomatal resistance, drought tolerance, high temperature stress response, disease tolerance, and oxidative stress response. It localises to the vacuolar membrane, tonoplast, plasmalemma, and chloroplast envelope. Studies of related genes in other species connect the family to sodium exclusion, ion homeostasis, and high-salinity stress tolerance.
