NHX1 — Beta vulgaris subsp. vulgaris
Summary
BvNHX1 (BVRB_4G083400) on sugar beet chromosome 4 encodes a sodium/hydrogen exchanger of the CPA1 family, with lithium:proton and potassium:proton antiporter activity. It is associated with vacuolar membrane transport, sodium import, lithium export, cell pH regulation, potassium ion homeostasis, and response to superoxide. The gene is linked to yield, photosynthetic rate, stomatal resistance, plant height, root development, and abiotic stress responses including high temperature and UV-B sensitivity. It has been connected to sodium uptake, iron concentration, phosphorus uptake, and disease tolerance. Related genes in other species link it to ion homeostasis, vacuolar pH regulation, potassium accumulation, and heat, cold, and drought tolerance.
