HKT1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G226240, the durum wheat gene TtHKT1 on chromosome 7A, encodes a transmembrane cation transporter with sodium and potassium transporter activity, belonging to the TrkH/K-transport family. This gene is associated with sodium and potassium ion membrane transport, regulation of sodium transporter activity, and potassium ion homeostasis. It localizes to the plasmalemma, Golgi membrane, and ER membrane. TtHKT1 is linked to salinity tolerance, seedling vigour, tiller number, germination rate, and chlorophyll content. Studies of related genes in other species connect the family to salt stress tolerance, potassium homeostasis, and shoot and root growth under saline conditions, while broader family associations include grain yield, plant height, sodium uptake, and drought tolerance.
