Abstract
Huang-jing (Polygonatum kingianum), an important herb in traditional Chinese medicine, is susceptible to anthracnose, a destructive foliar disease caused by Colletotrichum spp. In September 2020, irregular brown leaf spots were observed on P. kingianum plants in Yunnan Province, China. A Colletotrichum isolate was identified from the infected leaves, and its morphological features matched Colletotrichum nymphaeae. The fungus was further confirmed using molecular techniques, with gene sequences showing 99.27% to 100% homology to known C. nymphaeae strains. A pathogenicity test demonstrated that the fungus caused anthracnose symptoms in plants. This study represents the first report of C. nymphaeae causing anthracnose in P. kingianum in China, providing essential baseline data to inform future development of disease management strategies for this medicinal species.
期刊介绍：
Journal of Phytopathology publishes original and review articles on all scientific aspects of applied phytopathology in agricultural and horticultural crops. Preference is given to contributions improving our understanding of the biotic and abiotic determinants of plant diseases, including epidemics and damage potential, as a basis for innovative disease management, modelling and forecasting. This includes practical aspects and the development of methods for disease diagnosis as well as infection bioassays.
Studies at the population, organism, physiological, biochemical and molecular genetic level are welcome. The journal scope comprises the pathology and epidemiology of plant diseases caused by microbial pathogens, viruses and nematodes.
Accepted papers should advance our conceptual knowledge of plant diseases, rather than presenting descriptive or screening data unrelated to phytopathological mechanisms or functions. Results from unrepeated experimental conditions or data with no or inappropriate statistical processing will not be considered. Authors are encouraged to look at past issues to ensure adherence to the standards of the journal.
