NHX1 — Brassica juncea

Summary

BJUA06G32840S (BjNHX8, also known as NHX1 and SOS1) encodes a cation/H+ exchanger of the CPA1 family with lithium:proton antiporter, potassium:proton antiporter and sodium:hydrogen exchanger activities. It is associated with vacuolar membrane and tonoplast localisation, as well as chloroplast envelope and plasmalemma. The gene is linked to lithium export and transport, sodium import, cell pH regulation, photoprotection, detoxification, and responses to superoxide, ozone, hydrogen peroxide and stress. It has been connected to yield, chlorophyll content, photosynthetic rate, plant height, root development, drought tolerance, salt tolerance, disease tolerance, and abscisic acid and jasmonic acid sensitivity. Studies of related genes in other species link the family to lithium tolerance, high-salinity stress tolerance, sodium homeostasis, potassium uptake, heat tolerance and abiotic stress response.
