Abstract
Kiwifruit postharvest rot causes significant economic loss during handling process from field to table. In our attempt to identify pathogens associated with kiwifruits in 2019, about a quarter of cold-stored kiwifruits collected from Guizhou, China, were observed suffering postharvest rot. Diseased tissues were sampled for pathogen isolation. About 20% of the isolated pure cultures were identified to be Trichothecium roseum based on morphology and ITS sequence similarity. Identity was further supported by phylogeny analysis based on the LSU and TEF1α loci. Pathogenicity was confirmed on wounded kiwifruits and similar symptoms were observed. Koch's postulate was fulfilled by re-isolation of T. roseum from symptomatic inoculated fruits. To our knowledge, this is the first solid confirmation of this pathogen infecting kiwifruits and resulting in postharvest rot.
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.
