NHX1 — Nicotiana attenuata
Summary
A4A49_30789 (NHX1/NHX2) in coyote tobacco (Nicotiana attenuata) encodes a sodium/hydrogen exchanger belonging to the CPA1 cation/H⁺ exchanger family, with annotated lithium:proton antiporter, potassium:proton antiporter and sodium transporter activities. The gene is associated with vacuolar membrane transport, sodium and potassium ion membrane transport, cell pH regulation, and cellular 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 high temperature, UV-B light, abscisic acid and jasmonic acid. Associations also include drought tolerance, sodium tolerance, potassium tolerance, stomatal movement and regulation, cell expansion, root growth, gravitropism, auxin homeostasis and apical dominance. The protein localises to the tonoplast, vacuolar membrane, endosome, plastid and chloroplast envelope.
