植物致病镰刀菌细胞壁降解酶的研究进展

Research advances on cell wall degrading enzymes produced by pathogenic Fusarium causing plant diseases

镰刀菌是一类重要的寄生性植物病原真菌,细胞壁降解酶(Cell wall degrading enzyme)是镰刀菌侵入寄主使其致病的主要致病因子之一。本文主要从镰刀菌产生的细胞壁降解酶种类、作用机制、影响因素及其与植物抗菌次生代谢物之间的关系等方面,阐释其研究进展,以期为深入研究镰刀菌的侵染致病机制,进而为寻找新的病害控制措施提供思路。

Fusarium is an important type of parasitic pathogenic fungi. Cell wall degrading enzyme（ CWDEs） is one of the main pathogenic factors by which Fusarium invades and infects the host. This paper summarized the research on Fusarium from such aspects as the species of CWDEs produced by Fusarium,their mechanism of action,the factors affecting the production of CWDEs,and the relationship between CWDEs and the disease resistance metabolites of the host plants,in order to provide insights into the pathogenic mechanism of Fusarium so as to find new disease control measures.
