The Function of Chitinases CmCH1 and CmCH10 in the Interaction of <i>Coniothyrium minitans</i> and <i>Sclerotinia sclerotiorum</i>.

ABSTRACT: Sclerotinia sclerotiorum, a devastating phytopathogenic fungus with global distribution, exhibits a broad host range encompassing over 700 plant species. Sclerotinia stem rot caused by this pathogen poses a significant threat to sustainable oilseed rape production. Coniothyrium minitans, a mycoparasite of S. sclerotiorum, is a promising biological control agent against this devastating disease. C. minitans-based formulations have been commercially developed for field application. A transcriptomic analysis revealed significant upregulation of the chitinase-encoding gene CmCH1 in C. minitans during interaction with S. sclerotiorum. Knockout of either CmCH1 or another chitinase-encoding gene CmCH10 in C. minitans did not ma
