NHX1 — Brassica juncea

Summary

BJUA10G11100S, the NHX1 gene on chromosome A10 of Indian mustard (Brassica juncea), encodes a sodium:hydrogen exchanger with potassium:proton antiporter activity, belonging to the NaH_exchanger and cation/H_exchanger_CPA1 families. The protein is localised to the vacuolar membrane and plasmalemma. This gene is associated with vacuolar membrane transport, sodium import, cell pH regulation, potassium ion membrane transport, photoprotection, detoxification, calcium signaling, chlorophyll fluorescence, response to stress, homeostasis, and activation of salinity response. It has been linked to chlorophyll content and salt tolerance (SALTTL). Related genes in other species link the family to sodium sequestration and salt stress tolerance.
