Registration Date 12-01-2024 Organization Taras Shevchenko National University of Kyiv popup.description2 Objects of the research: risk factors for the emergence and spread of plant viral infections. The aim of the work: establishment and evaluation of the role of important risk factors for the emergence and spread of plant viral infections in agriecosystems of Ukraine. Methods of the research: virological, serological, molecular biological and statistical methods. We have complied the list of harmful viruses of commercially important plant crops, as well as have studied their spread, the host range and mechanisms of transmission. Screening of promising varieties of individual crops for (in)susceptibility to the corresponding viruses was carried out. The phylogenetic properties of the most dangerous plant viruses were studied in order to understand the basis of their virulence and the ways of their evolution, as well as methods of molecular diagnostics of such pathogens have been optimized, while the epidemic potential of dangerous viruses in the agroecosystems of Ukraine was analyzed. On the basis of the described properties of Ukrainian isolates of plant viruses, the risk factors for the appearance and spread of viral infections are described, taking into account epidemiologically important criteria. Principles of the virological management system for cost-effective use of biological resources and biosafety of Ukraine have been proposed. It was found that in the conditions of Ukraine, the main risk factors for the appearance and spread of viral plant diseases are the lack of regular monitoring of crops for viral diseases, the import of seeds/plant material, the variety of means of virus transmission, virus adaptability, vector’(s) circulation, wide susceptibility of plant varieties to certain viruses and/or lack of resistant varieties, non-compliance with agricultural techniques and anthropogenic pollution of agroecosystems.   Product Description popup.authors Andriichuk Olena M.
