Effects of Bacillus velezensis CB13 treatment on the activities of enzymes related to resistance in Sclerotium rolfsii-induced peanut leaves. (A) phenylalanine ammonia-lyase; (B) polyphenol oxidase; (C) peroxidase; (D) catalase; (E) superoxide dismutase; (F) ascorbate peroxidase; (G) β-1,3-glucanase and (H) chitinase. Uninoculated, uninfected, and untreated plants; CB13, peanut plants watered with 20 mL of bacterial inoculum alone; Inoculated peanut plants infected with S. rolfsii alone; CB13 + inoculated, seeds were soaked in bacterial inoculum for 24 h before sowing and then infected with S. rolfsii. Data are the means ± SE of three repeated experiments. Significant differences are shown using asterisks (*p < 0.05, **p < 0.01, and ***p < 0.001).
