SAPK2 — Oryza sativa Japonica

Summary

OsSAPK2 (also known as SAPK9, SAPK2, and SAPK3) on rice chromosome 12 encodes a serine/threonine protein kinase with ATP binding activity. This gene is associated with resistance to bacterial blight, drought tolerance, salt stress tolerance, and yield-related traits including grain size, tiller number, and grains per panicle. It is linked to abscisic acid signaling, nitrogen utilization, nitrate import, programmed cell death, seed germination, seedling development, root development, and jasmonic acid signaling. The protein localizes to the cytosol, cytoplasm, and nucleus.
