Programmed cell death (PCD) occurs in plants, animals and several branches of unicellular eukaryotes as a part of developmental and/or defense processes. Caspase proteases are universal mediators of animal apoptosis, a type of PCD. In plants, there are not animal caspase homologs; therefore, the characterization of caspase-like activities is of considerable importance to our understanding of PCD in plants. Here we report for the first time the involvement of caspase-3-like activity in the resistance mechanism of potato to Phytophthora infestans infection. We showed that disease development in infected potato leaves is dependent of caspase-3-like activityfirst time the involvement of caspase-3-like activity in the resistance mechanism of potato to Phytophthora infestans infection.
