Interactions between ectomycorrhizal fungi (Suillus laricinus, S.
tomentosus, Amanita vaginata and Gomphidius viscidus) and the pathogen
Rhizoctonia solani in co-culture were studied using both light and
scanning electron microscopy. S. laricinus, S. tomentosus and A.
vaginata inhibited the growth of the pathogen. Moreover, A. vaginata
exhibited coiling around and penetration of the hyphae into R. solani
was observed in the interaction zone. Furthermore, the production of
chitinases, beta-1,3-glucanases and beta-glucosidases by these
ectomycorrhizal fungi on colloidal chitin or cell walls of R. solani
was evaluated: chitinases were not induced by colloidal chitin but all
three enzymes were induced by R. solani cell walls. No correlation
between inhibition rate and production of lytic enzymes was found.
