Light and electron microscope observations on chlorotic rusty spot, a disorder of cherry in Italy
Journal of Plant Pathology 85 (3), 215-218
Abstract: Cherry chlorotic rusty spot (CCRS), a disease found in southern Italy, is similar to Amasya cherry disease, described in 1970 in Turkey. The same set of doublestranded (ds) RNAs was found associated with both diseases. Light and electron microscopy showed the presence of a fungus-like organism in naturally infected Italian and Turkish cherry material. Attempts to culture, isolate and identify the fungus failed. Although the dsRNAs and the fungus were regularly associated with the diseases, the relationships between them are not yet clear. The possibility exists that the CCRS and Amasya-associated dsRNAs could be genome components of a fungal virus.
