Pathogenic Fungi Induce the Expression of Trichoderma asperellum Cell Wall Degrading Enzymes in the Process of Mycoparasitism

Abstract:

Trichoderma asperellum is an important biocontrol fungus which has been shown to control plant soil-borne pathogens, such as: Pythium ultimum, Fusarium oxysporum, Cytospora chrysosperma and Sclerotinia sclerotiorum. The goal of this research is to study whether the cell wall degrading enzymes genes were induced by pathogens or not in the process of T. asperellum mycoparasitism. The results suggest that chitinase gene ech42, β-1,3 glucanase gene bgn13.1, and β-1,6 glucanase gene bgn16.1 can be induced by pathogens. However, two N-acetyl-amino glycosidase nag1 and nag2 can not be induced by pathogens.
