PDC and infection: In order to decrypt how the simultaneous infection by F. circinatum and Phytophthora species affects the plant defense response, this study describes the modulation of the SAR and plant cellular respiration by the analysis of the transcriptomic profile of three genes encoding for pathogenesis-related proteins (PR3, PR5, and PAL) as well as that of the pyruvate decarboxylase- (PDC) encoding gene.
