NHX1 — Beta vulgaris subsp. vulgaris
Summary
BvNHX1 (BVRB_9G203100) on sugar beet chromosome 9 encodes a sodium/hydrogen exchanger of the CPA1 family, with lithium:proton and potassium:proton antiporter activities. It is associated with vacuolar membrane transport, sodium import, potassium ion homeostasis, cell pH regulation, and responses to superoxide. The gene is linked to yield, photosynthetic rate, stomatal resistance, plant height, root development, and abiotic stress responses including salt and high temperature tolerance. It has been connected to sucrose anabolism, nitric oxide production, and protein localization to the plasma membrane. Related genes in other species are linked to ion homeostasis, vacuolar pH regulation, sodium exclusion, potassium accumulation, and tolerance to drought, heat, cold, and alkaline stress.
