HKT1 — Triticum turgidum subsp. durum

Summary

TRITD7BV1G172380 (symbol HKT1, preferred name TtHKT1) on durum wheat chromosome 7B encodes a high-affinity potassium transporter protein with transmembrane cation transporter activity, including sodium and potassium transporter activity and symporter activity. It is associated with sodium and potassium ion membrane transport, regulation of sodium transporter activity, and potassium ion homeostasis. The gene is associated with salinity tolerance, seedling vigour, tiller number, germination rate, and chlorophyll content. The product localises to the plasmalemma, Golgi membrane, and ER membrane. Related genes in other species are linked to salt stress, potassium homeostasis, shoot and root growth, grain yield, plant height, sodium uptake, and drought tolerance.
