Abstract: Anthracnose is one of the major leaf diseases of many plants such as walnut and chestnut in the world, its pathogen is Colletotrichum gloeosporioides which is destructive to a vast variety of plants important to forestry and caused large economic losses to production. The infection process includes the prophase biotrophic stage, middle stage and late death nutritional stage. In this study, the cloned gene in infection process was reviewed, and heredity relationship was analyzed based on ITS data of Colletotrichum genus, to further research the pathogen and make effective control strategy of anthracnose.
