HKT1 — Triticum turgidum subsp. durum
Summary
TRITD2BV1G212000, designated TtHKT1 on durum wheat chromosome 2B, encodes a transmembrane cation transporter with sodium and potassium transporter activity, belonging to the TrkH potassium transport family. This gene is associated with salinity response, osmotic response, and potassium ion homeostasis, as well as sodium and potassium ion membrane transport. It has been 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. The encoded protein localises to the plasma membrane, Golgi membrane, ER membrane, and mitochondria. Studies of related genes in other species link the family to sodium homeostasis, salt tolerance, and shoot sodium accumulation, as well as salt stress, ion homeostasis, and reproductive development.
