NHX1 — Beta vulgaris subsp. vulgaris

Summary

BvNHX1 (BVRB_1G006450) on sugar beet chromosome 1 encodes a sodium/hydrogen exchanger belonging to the NaH_exchanger and cation/H_exchanger_CPA1 families, with lithium:proton and potassium:proton antiporter activities. This vacuolar membrane and tonoplast protein is associated with sodium import, lithium export, cell pH regulation, potassium ion homeostasis, and sucrose anabolism. It has been linked to yield, photosynthetic rate, stomatal resistance, plant height, root development, and responses to abiotic stress including high temperature, UV-B light, and salinity. Associations also include iron and phosphorus uptake, auxin content, abscisic acid sensitivity, and disease tolerance. Related genes in other species connect this gene to vacuolar pH homeostasis, potassium accumulation, sodium tolerance, and heat and cold tolerance.
