HKT1 — Zea mays
Summary
ZM00001EB130310, designated HKT1 on maize chromosome 3, encodes a transmembrane cation transporter with sodium and potassium transporter activity, belonging to the TrkH/K-transport family. The gene is associated with potassium and sodium ion membrane transport, potassium ion homeostasis, and tissue homeostasis. It has been linked to numerous agronomically important traits including salt stress tolerance, sodium exclusion, leaf relative water content, net photosynthetic rate, water use efficiency, chlorophyll content, plant height, biomass yield, root length and volume, seedling vigor, and total soluble sugar content. The encoded protein localizes to the plasma membrane, Golgi membrane, ER membrane, and mitochondria. Studies of related genes in other species link the family to salt tolerance, sodium homeostasis, and potassium nutrition.
