HKT1 (TRAESCS2B02G451600) — triticum aestivum
Summary
TRAESCS2B02G451600 (HKT1;4) on wheat chromosome 2B encodes a transmembrane cation transporter with sodium and potassium transporter activity and symporter activity, belonging to the TrkH/K-transport family. This gene is associated with salinity response, osmotic response, potassium ion homeostasis, and C4 photosynthesis. It has been linked to numerous agronomically important traits including salt stress tolerance, sodium concentration, grain protein content, spikelet number, seed size, grain number, stripe rust resistance, heat tolerance, cold tolerance, drought tolerance, chlorophyll content, net photosynthetic rate, transpiration rate, stomatal resistance, root length, seminal root length, coleoptile length, cell membrane stability, germination rate, and stand establishment. The encoded protein localizes to the plasma membrane, Golgi membrane, ER membrane, and mitochondria. Studies of related genes in other species link the family to sodium transport, ion homeostasis, and salt tolerance.
