Effects of physiological stresses, nutrients, CAT inducers and CAT inhibitors on inter-specific CAT fusion frequency in C. gloeosporioides and C. siamense. Inter-specific CAT fusion percentage in water, PDB, oxidative stress (H₂O₂), osmotic stress (NaCl and sorbitol), heat, antifungal stress, glucose, KNO₃, combination of glucose and KNO₃, NaNO₃, MgCl₂, tryptophan, Insolution™ PD98059 (inhibitor of MAPKK pathway). Average from 3 replicates (n = 3) and 150 conidial pairs were counted per replicate. Bar indicates standard deviation. Statistical significance of differences was analyzed by one-way ANOVA with Tukey’s multiple comparison post-hoc test (bars with the same letter are not significantly different; p ≤ 0.05)
