KT1 — Oryza sativa Japonica

Summary

OS06G0625900, also known as KT1 or HAK10, encodes a protein with potassium transporter activity, sodium transporter activity, RNA binding, and zinc binding. It is associated with potassium ion transport, response to salt, pollen germination and development, leaf senescence, mRNA processing, cellular homeostasis, and glutathione metabolism. The gene has been linked to vacuolar membrane, mitochondria, and plasmalemma localization. In rice, HAK10 is associated with salt stress, and associations with potassium and sodium concentration, potassium uptake, chlorophyll and proline content, germination rate, grain yield, and drought tolerance have been reported. Studies of related genes in other species link the pentatricopeptide repeat-containing protein family to RNA processing, and yeast studies connect the transporter family to ion transport.
