NHX8 — Triticum turgidum subsp. durum
Summary
TRITD3BV1G005720 (symbol NHX8, also known as TtNHX8, TtSOS1, or SOS1) on durum wheat chromosome 3B 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, lithium export, sodium import, cell pH regulation, vacuolar membrane and tonoplast localisation, and responses to reactive oxygen species, ozone, hydrogen peroxide, and jasmonic acid. The gene is linked to yield, grain yield, plant height, root development, photosynthetic rate, stomatal resistance, drought tolerance, disease tolerance, and high-temperature stress response. Studies of related genes in other species connect the family to sodium exclusion, ion homeostasis, and salt tolerance.
