Canker symptoms and SA/JA production changes of M. sieversii after V. mali infection. a. The twigs and leaves of M. sieversii inoculated with V. mali. Mock: wounds + ddH2O, 5 dpi: wounds + V. mali; Scale bar, 2 cm. b. The productions of free SA and JA (ng/g FW) of twigs inoculated with V. mali at 0, 0.5, 1, 3, 6, 24, 48, 120 hpi. c. The relative expressions of SA and JA related-genes of twigs inoculated with V. mali at 0, 0.5, 1, 2, 3, 6, 24, 36 hpi. Lipoxygenase 3 (LOX3), allene oxide cyclase 4 (AOC4), coronatine-insensitive protein 1 (COI1), isochorismate synthase 1 (ICS1), phenylalanine ammonia-lyases 1 (PAL1), non-expressor of pathogenesis-related (PR) genes 1 (NPR1), pathogenesis-related protein 5 (PR5), pathogenesis-related protein 10 (PR10). Asterisks indicate significant differences (*p<0.05; **p<0.01; LSD’s test) between each infection timepoints and the 0-hpi control
