HKT1 — Hordeum vulgare subsp. vulgare

Summary

HORVU.MOREX.R3.7HG0727320, designated HvHKT1 on barley chromosome 7H, encodes a transmembrane cation transporter with sodium and potassium transporter activity and symporter activity, belonging to the TrkH-K_transport and Cat_transpt domain families. The gene is associated with sodium and potassium ion membrane transport, regulation of sodium transporter activity, and potassium ion homeostasis. It has been linked to salinity tolerance, sodium concentration, plant height, and relative plant height. The encoded protein localises to the plasmalemma, Golgi membrane, and ER membrane. Studies of related genes in other species connect the family to sodium uptake, seedling vigour, grain yield, drought tolerance, and canopy temperature.
