Abstract:

Trichoderma spp.was a broad spectrum antagonistic fungus which could antagonized a variety of pathogenic fungi, mycoparasitism was main mechanism of Trichoderma biological control. To master the molecular mechanisms was in favor of reasonable application and transformation of Trichoderma, therefore, this article reviewed the molecular mechanism research progress of Trichoderma mycoparasitism, including the signal transduction of Trichoderma mycoparasitism and the hydrolytic enzymes producing in the process of mycoparasitism which hydrolysis of pathogenic fungi cell wall. Trichoderma signal transduction pathways in the process of mycoparasitism was heterotrimeric G-proteins and mitogen-activated protein kinase (MAPK) cascades, the cell wall-degrading enzymes of Trichoderma included chitinase, glucanase and protease.
