title: [Properties of potato virus M and potato virus Y isolates in Ukraine].
abstract: Monitoring of viruses of tomato plants (Lycopersicon esculentum Mill.) was carried out. Twenty-seven varieties of tomatoes from different regions of Ukraine were tested for the virus presence. New symptoms, which had not been described before, were revealed. It was found out that the diseases were caused by Potato virus M and Potato virus Y. This is the first report about the infection of tomato plants with such viruses in Ukraine. Some biological, physical and chemical properties of the pathogens are studied. Differences between PVM, PVY and the known isolates were found in morphology and molecular weight of structural protein.
