HKT1 — triticum aestivum

Summary

TRAESCS7B02G318400 (HKT1, also known as TaHKT1-7B or HKT2;1) on bread wheat chromosome 7B encodes an uncharacterized protein belonging to the Trk/HKT family, with transmembrane cation transporter, sodium transporter, and potassium transporter activity. This gene is associated with sodium and potassium ion membrane transport, regulation of sodium transporter activity, potassium ion homeostasis, and water transport. It has been linked to salinity tolerance, drought tolerance, grain yield, seedling vigour, tiller number, canopy temperature, stand establishment, germination rate, chlorophyll content, proline content, and sodium concentration. The encoded protein localises to the plasmalemma, Golgi membrane, and ER membrane. Related genes in other species are associated with salt stress tolerance, sodium uptake, and potassium homeostasis.
