The calciumdependent kinase 3 (CPK3) has been demonstrated to be a positive regulator of PCD in plants. Sphingosine or phytosphingosine (PHS) activate CPK3 which phosphorylates its binding partner, the 1433 proteins. This binding leads to the disruption of the CPK31433 protein complex and CPK3 degradation. Moreover,
