HKT1 — Medicago truncatula

Summary

MTR_6G092970 (MtHKT1) on barrel medic chromosome 6 encodes a transmembrane cation transporter with sodium and potassium transporter activity and symporter activity, belonging to the TrkH_K-transport and Cat_transpt domain families. The gene is associated with regulation of sodium transporter activity, sodium and potassium ion membrane transport, metal ion transport, potassium ion homeostasis, and responses to salt, salinity, and osmotic stress. It has been linked to photosynthetic rate, chlorophyll content, salt tolerance, sodium ion accumulation and homeostasis, sodium exclusion, potassium retention, seed production, seed germination under salt stress, and lateral root development. The encoded protein localises to the plasmalemma, Golgi membrane, ER membrane, and mitochondria. Studies of related genes in other species connect the family to sodium transport, recirculation, homeostasis, potassium uptake, and ion distribution.
