- Abstract
Anthracnose is one of the most important diseases of Heptacodium miconioides subsp. jasminoides, which seriously affects plant growth and threatens the survival of this rare species. To clarify the causative pathogen, infected leaves of H. miconioides subsp. jasminoides were collected, and the pathogen was obtained by the tissue isolation method. After determining the pathogenicity of the isolated strains, both morphological and multi-gene approaches were applied to identify the causative pathogen. Three strains were isolated, and only one isolate namely QZH could cause anthracnose disease according to Koch’s Rule. The morphological characteristics were identical with those of Colletotrichum fructicola. The multi-gene analysis results indicated that QZH and C. fructicola shared the same clade, with high support rates. Based on the morphological characteristics and multi-gene identification results, it was confirmed that the pathogen causing anthracnose disease of H. miconioidessubsp. jasminoides was C. fructicola. These data provided a start point for both disease prevention and pathogenic mechanism studies in the future.
