NHX8 — Brachypodium distachyon
Summary
BdNHX8 (BRADI_4G00290V3) on chromosome 4 of Brachypodium distachyon encodes a cation/H⁺ exchanger of the CPA1 family with lithium:proton antiporter, sodium:hydrogen exchanger, and potassium:proton antiporter activities, as well as NAD ADP-ribosyltransferase and protein kinase activities. It is associated with vacuolar membrane and tonoplast localisation, and linked to lithium export and transport, sodium import, cell pH regulation, and responses to superoxide, hydrogen peroxide, ozone, and ethylene- and jasmonic acid-mediated signalling. The gene has been connected to yield, plant height, root thickness, photosynthetic rate, stomatal resistance, drought tolerance, salt tolerance, and disease tolerance. Related genes in other species link the family to sodium exclusion, ion homeostasis, and high-salinity stress tolerance.
