HKT1 — Hordeum vulgare subsp. vulgare
Summary
HORVU.MOREX.R3.2HG0192270, designated HvHKT1 on chromosome 2H of domesticated barley, encodes a transmembrane cation transporter with sodium and potassium transporter activities, belonging to the TrkH/K-transport family. The gene is associated with salinity response, osmotic response, potassium ion homeostasis, and regulation of sodium transporter activity. Its product localises to the plasmalemma, Golgi membrane, ER membrane, and mitochondria. HvHKT1 is associated with sodium concentration, plant height, photosynthetic rate, and the SALTTL trait, as well as phenotypes including salt stress tolerance, sodium exclusion, potassium retention, seed germination under salt stress, and reproductive growth. Studies of related genes in other species link the family to salt tolerance, sodium homeostasis, and shoot sodium accumulation, as well as salt stress and ion homeostasis.
