KT1 — Oryza sativa Japonica

Summary

OsKT1 (OS01G0369300) encodes a potassium transporter family protein with potassium transporter, sodium transporter, and potassium:sodium symporter activities, and also carries domains characteristic of potassium transporters. The gene is associated with potassium ion import across the plasma membrane, potassium ion membrane transport, regulation of stomatal movement and closure, response to salt, and regulation of ROS metabolic process. It is linked to traits including potassium and sodium concentration, grain yield, seed yield, biomass yield, water use efficiency, transpiration rate, root hair length, leaf elongation rate, chlorophyll content, and low temperature stress response. Studies of related genes in other species connect the family to pollen development, fertility, seed setting rate, lateral root and root hair growth, auxin transport, and tiller architecture. The protein localises to the plasma membrane, vacuolar membrane, cytosol, nucleus, and mitochondria.
