Abstract

Abstract: Sclerotinia sclerotiorum（Lib.） de Bary is an important phytopathogenic fungus in the worldwide. S. sclerotiorum has a wide host range and can infect many kinds of crops. Sclerotinia diseases causes significant yield losses and economic damage of many crops. S. sclerotiorum is an necrotrophic phytopathogenic fungus,which obtain nutrient from plant by killing host cells and destroying host tissue. Previous studies focused on the role of hydrolytic enzymes（cutinase,cell wall degrading enzymes and proteases） and oxalic acid during infection. The pathogenicity mechanism of S. sclerotiorum is extremely complicated,more and more recent studies have shown that secreted proteins also play an important role in the interaction of host and S. sclerotiorum. Secreted proteins facilitate the invasion and colonization of S. sclerotiorum by inducing plant cell death or suppressing host cell immune responses. This review summarizes the latest research progress on the pathogenesis of S. sclerotiorum including hydrolases,oxalic acid,secreted proteins and other pathogenic proteins. We also prospect the research of pathogenicity mechanism of S. sclerotiorum,in order to provide new ideas and theoretical basis for the safety and control of Sclerotinia disease.

Key words: Sclerotinia sclerotiorum, pathogenesis, secretary protein, hydrolase, oxalic acid
