HKT1 — Triticum turgidum subsp. durum

Summary

TRITD7AV1G225880 (symbol HKT1, preferred name TtHKT1) on durum wheat chromosome 7A encodes a transmembrane cation transporter with sodium and potassium transporter activity and symporter activity, belonging to the TrhK_K-transport and Cat_transpt domain families. The gene is associated with sodium and potassium ion membrane transport, regulation of sodium transporter activity, potassium ion homeostasis, and metal ion transport, and its product localises to the plasmalemma, Golgi membrane, and ER membrane. TtHKT1 has been associated with salinity tolerance, seedling vigour, tiller number, germination rate, and chlorophyll content. Related genes in other species are linked to salt stress, potassium homeostasis, shoot and root growth, sodium uptake, grain yield, plant height, and drought tolerance.
