PPOX and infection: As shown in Figure 6, the results indicate that following the infection of A. phaeospermum, the levels of defense enzymes (CAT, PPO, POD, SOD, GPX, PAL), chlorophyll, total phenols, and plant hormones in the three transgenic lines (OE-BDUbc, OE-BDSKL1, and OE-BDUbc + BDSKL1) were higher compared to the wild-type plants.
