PPO activity in leaves and roots of common bean following treatment with live pathogen and pathogen fragments. Foliage of common bean (Phaseolus vulgaris) was inoculated with live Colletotrichum gloeosporioides and treated with C. gloeosporioides fragments. Polyphenol oxidase (PPO) activity in leaves (a) and roots (b) was measured (n =9 plants per day; 63 plants total per treatment) over an experimental period of 7 days. Values shown are means ± SD. Letters next to data points indicate significant differences within each pathogen treatment group according to post-hoc analysis (Tukey’s HSD; P <0.05) after one-way ANOVA. ***P <0.001, *P <0.05, ns P >0.05 between treatment groups according to t-test.
