KT1 — Oryza sativa Japonica

Summary

OsKT1 (OS09G0448200) encodes a potassium transporter with K_trans_C and K_trans_N domains, possessing both potassium and sodium transporter activity. It is localized to the membrane and plasmalemma. The gene is associated with potassium ion transport, response to salt, salinity response, pollen development and germination, leaf senescence, cellular homeostasis, and glutathione metabolism. It has been linked to traits including potassium concentration and uptake, sodium concentration, relative chlorophyll and chlorophyll content, sucrose and proline content, germination rate, grain yield, salt tolerance, and drought tolerance. Related genes in other species are linked to saline-alkaline stress tolerance.
