Natural variations in the OsCPK9 promoter confer chilling tolerance in rice by stabilizing OsSAPK8 through phosphorylation
Our findings demonstrated that the OsCPK9-OsSAPK8 module regulates chilling tolerance through Ca<sup>2+</sup>-mediated phosphorylation during the early stages of cold signal transduction. Furthermore, the elite allelic variation of OsCPK9 is an excellent candidate site for precise editing to enhance rice's tolerance to chilling stress.
