NHX1 — Nicotiana attenuata
Summary
A4A49_37316, designated NHX1 (also known as NHX6 and several other synonyms) on chromosome 1 of coyote tobacco (Nicotiana attenuata), encodes a sodium/hydrogen exchanger belonging to the NaH_exchanger and cation/H_exchanger_CPA1 families. The product exhibits lithium:proton antiporter, potassium:proton antiporter, sodium:hydrogen exchanger, and sodium transporter activities. NHX1 is associated with vacuolar membrane transport, sodium import, lithium export, cell pH regulation, potassium ion homeostasis, and response to superoxide. It localizes to the tonoplast, vacuole, endosome, and plastid. The gene is associated with leaf potassium content, sodium uptake, yield, photosynthetic rate, stomatal resistance, plant height, root development, and responses to high temperature, UV-B light, and abiotic stress. Associations also include drought tolerance, auxin homeostasis, gravitropism, and seed storage protein processing.
