Abstract: To protect themselves against diverse pathogens, plants produce pathogenesis-related (PR) proteins as parts of constitutive and induced chemical defenses.In this study, we investigated the systemic and local induction of two PR proteins, ß-1,3response to Phytophthora palmivora infection in resistant Dendrobium and systemic induction of ß-1,3-glucanase were observed in highly resistant mutants SUT13E18301 induced chitinase activities in both distal and infected leaves.Interestingly, the up-regulated protein bands but not in the non-mutagenized controls.Some of these proteins appeared to be associated with ß-1,3-glucanase and chitinase activities, suggesting that these unique protein bands may be related to antifungal activities during the infection of P. palmivora and may be used as in orchids.These biochemical characteristics provide insight into the resistance mechanism of Dendrobium against P. palmivora and may be effectively utilized to characterize other putative D resistance resource for future breeding programs.
