摘要
木霉 (Trichoderma spp.)作为重要的植病生防因子 (biocontrol agents)一直受到普遍关注。木霉菌株产生的包括几丁质酶在内的细胞壁降解酶 ,在木霉重寄生中起重要作用。本文论述木霉几丁质酶的种类、诱导产生、理化特性及其对植物病原真菌的拮抗作用 ,并对木霉几丁质酶及其基因的生防应用进行讨论。
Some Trichoderma strains are promising biocontrol agents (BCAs) of plant disease. It is observed that chitinolytic enzymes of Trichoderma play an important role in mycoparasitism which is considered as one of the mechanisms involved in the antagonism of Trichoderma against plant fungal pathogens. The induced production, the physical and chemical characteristics of chitinases from Trichoderma strains and their antagonism against plant fungal pathogens are reviewed in the present article, and the potential use of the chitinases and chitinase genes from Trichoderma for biological control is also discussed.
