title: Hyphal in vitro growth of the arbuscular mycorrhizal fungus Glomus mosseae is affected by chitinase but not by β-1,3-glucanase.
abstract: Purified basic chitinase or β-1,3-glucanase or a combination of the two enzymes were applied to hyphae of the arbuscular mycorrhizal fungus Glomus mosseae grown in vitro. Chitinase applied to the hyphal tip produced an inhibition of hyphal extension, lysis of the apex and alterations of the growth pattern of the fungus. No effect was observed, however, when chitinase was applied to subapical parts of the hyphae or when glucanase was applied to any part of the hyphae. Application of a combination of the two enzymes to the hyphal tip produced an effect similar to that of chitinase alone.
