HKT1 — Oryza sativa Japonica
Summary
OS01G0307500, designated HKT1 (also known as SKC1, HKT1;5), encodes a transmembrane cation transporter with sodium and potassium transporter activity, belonging to the TrkH-K_transport family. In rice, this gene is associated with salt stress tolerance, sodium and potassium ion homeostasis, and localization to the plasma membrane, xylem, phloem, and vascular bundles. It has been linked to leaf, shoot, and root development, as well as responses to desiccation and salinity. Associations extend to agronomically important traits including grain number, grain size, grain weight, grain yield, plant height, panicle length, leaf angle, chlorophyll content, photosynthetic rate, water use efficiency, germination rate, root length, and drought tolerance. Studies of related genes in other species connect the family to sodium homeostasis, salt tolerance, and ion distribution.
