Interactions between lifestyle (pathogenic or non-pathogenic) and substrates. Fitted values from mixed-effect model on activity standardized within substrates. Lifestyle [non-pathogenic (NP) or pathogenic (P)], substrate (FP, XG, XY, AXW, AL, SS, CS, SG) and the lifestyle*substrate interaction were treated as fixed effects; genus/species/isolate were nested random effects. Data used for this analysis included 47 species of pathogens and 16 species of non-pathogens. Non-pathogenic and pathogenic species are the same as presented in Table 1 with the addition of three pathogens of woody species, Cylindrocarpon didymum, Fusicoccum aesculi and Schizophyllum commune. Pathogenic species had significantly higher activity on the substrates FP, AXW, AL, SS, CS and SG as determined by pairwise t-tests on fitted values from the model (P < 0.005). There was no significant difference on XG (P = 0.059) and XY (P = 0.08). The middle black bar at the center of the notch indicates the median value, edges of boxes indicate the interquartile range and whiskers indicate minimum and maximum values.
