Roles of MAPKs in bacterial-fungal and fungal-fungal interactions. a. Antagonistic activity of B. velezensis towards the wild type and Gpmk1 mgv1 Fghog1 triple mutant. b. The inhibitory effects of B. velezensis on conidium germination (6 h) and germ tube growth (12 h). Scale bars, 20 μm. c. The formation of swollen hyphal compartments in the triple mutant stimulated by B. velezensis. Scale bars, 50 μm. Conidia were indicated by arrows. d. Antagonistic activity of B. velezensis towards the wild type and Gpmk1, mgv1, and Fghog1 mutants. e. 16-day-old CM confrontation-cultures of C. rosea (top) with the wild type or triple mutant of F. graminearum (bottom) with the initial contact zone amplified on the right to show stimulated conidiation in C. rosea. Mean and standard deviation were estimated with data from at least three (n = 3) independent biological replicates. NS indicates no significant differences based on Student’s t-test
