NHX1 — Nicotiana attenuata
Summary
A4A49_13700 (NHX1) in coyote tobacco (Nicotiana attenuata) encodes a sodium/hydrogen exchanger of the CPA1 family, with lithium:proton and potassium:proton antiporter activity. This gene is associated with vacuolar membrane transport, sodium import, cell pH regulation, and potassium ion homeostasis. It has been linked to leaf potassium content, sodium uptake, yield, photosynthetic rate, stomatal resistance, transpiration rate, root development traits, plant height, and responses to UV-B light, high temperature, and abiotic stress. Associations also include disease tolerance, abscisic acid sensitivity, and jasmonic acid sensitivity. The encoded protein localizes to the tonoplast, vacuole, endosome, and chloroplast envelope. Studies of related genes in other species connect the NHX family to ion homeostasis, salt tolerance, drought tolerance, and auxin-mediated development.
