Abstract

Camellia sinensis and C. japonica plant leaves with spots were collected in Zhejiang Province, China. Three representative isolates resembling Nigrospora were selected for identification and pathogenicity test. Based on morphological characteristics and phylogenetic analyses of the partial regions of internal transcribed spacer (ITS), beta-tubulin (TUB2), and translation elongation factor 1-alpha (TEF) sequences, the isolates from C. japonica were identified as Nigrospora. oryzae and N. philosophiae-doctoris, while the one from C. sinensis as N. camelliae-sinensis. Inoculation of the isolates on healthy leaves showed symptoms similar to those observed in the field, and the fungi were reisolated from the lesions. To our knowledge, this represents the first report of leaf spot disease caused by Nigrospora species on C. japonica worldwide. The result further confirms that species residing the genus of Nigrospora act as causal agents of plant leaf spot disease, and their potential impact deserves further investigation.

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.
