摘　　要：植物病原真菌在侵染植物的过程中会分泌细胞壁降解酶来破坏植物细胞壁,以达到成功入侵寄主的目的。研究表明,病原菌分泌的细胞壁降解酶中的纤维素酶、果胶酶、木聚糖酶、几丁质酶、酯酶均参与了植物细胞壁的降解和病原菌致病的过程,但是对于细胞壁降解酶中的裂解多糖单加氧酶在病原菌侵染植物过程中的功能研究较少。根据近年来辅助活性酶类以及属于辅助活性酶类中的裂解多糖单加氧酶的研究进展,综述了辅助活性酶的分布、种类、功能以及裂解多糖单加氧酶植物病害中的作用研究,旨在为辅助活性酶类在植物病害中的功能研究和病害防控提供参考和依据。During the process of infecting plants,phytopathogenic fungi secrete cell wall degrading enzymes to destroy plant cell walls in order to successfully invade the host.Studies have shown that cellulase,pectinase,xylanase,chitinase,and esterase in the cell wall degrading enzymes secreted by pathogenic bacteria are involved in the process of plant cell wall degradation and pathogenic bacteria.However,there is relatively little research on the function of the lytic polysaccharide monooxygenase in the cell wall degrading enzymes in the process of pathogen invasion of plants.Based on the recent research progress of auxiliary active enzymes and cleavage polysaccharide monooxygenases belonging to the auxiliary active enzymes,this article summarizes the distribution,types,functions of auxiliary active enzymes and the role of cleavage polysaccharide monooxygenases in plant diseases.The research aims to provide reference and basis for the function research and disease prevention and control of auxiliary active enzymes in plant diseases.
