NHX8 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.3HG0221490 (HvNHX8) on barley chromosome 3H encodes a cation/proton exchanger of the CPA1 family with lithium:proton antiporter, sodium:hydrogen exchanger and potassium:proton antiporter activities. The gene is associated with sodium and lithium transport and homeostasis, vacuolar membrane transport, cell pH regulation, and responses to superoxide, hydrogen peroxide and ozone. It is linked to activation of salinity response, systemic acquired resistance, jasmonic acid and ethylene signalling, and regulation of reactive oxygen species. Associations include yield, plant height, root development, photosynthetic rate, stomatal resistance, chlorophyll content, and tolerance to drought, high temperature, oxidative stress and disease. Studies of related genes in other species connect the family to sodium exclusion, ion homeostasis and salt tolerance.
