The Antibiosis of Trichoderma asperellum Resistance Plant Pathogenic Fungi

Abstract:

T. asperellum has been turned out was an important biocontrol fungus and can antagonize many plant pathogenic fungi through a variety of biocontrol mechanisms. The antibiosis was considered one of important mechanisms. The antibiosis of T. asperellum resistance plant pathogenic fungi was examined in this paper. The antibiotic biosynthetic gene polyketide synthase gene pksT1 can be induced by pathogens. Moreover, the growth of the plant pathogens was inhibited by T. asperellum secondary metabolites. The yield of antibiotic 6-PP was 1.32 mg 6-PP/g mycelial dry weight. T. asperellum control plant pathogens through producing antifungal metabolites.
