HKT1 — Triticum turgidum subsp. durum

Summary

TRITD2BV1G211910 (HKT1, TtHKT1) on durum wheat chromosome 2B 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, and potassium ion homeostasis, and its product localises to the plasma membrane, Golgi, ER and mitochondria. HKT1 is linked to seedling vigour, tiller number, germination rate, photosynthetic rate, chlorophyll content, and salt tolerance traits including sodium exclusion, potassium retention, and seed germination under salt stress. It has been connected to sodium ion accumulation, xylem transport, leaf and shoot sodium distribution, and reproductive growth. Studies of related genes in other species link the family to salt tolerance, sodium homeostasis, and ion distribution, as well as shoot sodium accumulation and development.
