Infection structures formed in C. rosea G67-1 strain against B. cinerea. (a) Hook-like structures of G67-1 formed at 72 h after encountering B. cinerea. (b) Production of appressoria and penetration into host hyphae. (c) Appressorium branches produced inside host cells. (d) Disintegration of B. cinerea after 6 days. Mycoparasitic interaction between the two isolates was observed using a fluorescence microscope under phase-contrast, differential interference contrast (DIC), and normal fields.
