To analyze the already known results of virological tests and to investigate virus diseases in agricultural lands and forest ecosystems. Methods. Visual examination, enzyme-linked immunosorbent assay in various modifications, allocation of total RNA from plant material, purification of cDNA, electrophoresis of nucleic acids, CT-PCR, and method of statistical data processing. Results. They analyzed the results of domestic and foreign researches on phytovirusology. Joint research was conducted in the Institute of Agroecology and environmental management of NAAS and the National University of life and environmental Sciences of Ukraine regarding the prevention of viral infections of plants at the use of the composition of basidiomycetes fungi. For the recovery of plants from viral diseases, they used a process of simulated microgravity. Conclusions. Taking into account scientific, environmental and social importance of biological security in agriculture as an important condition of balanced development of Ukraine and the production of quality food products, agriculture and forestry should be based primarily on the use of quality certified diseasefree seed of resistant varieties. So pressing is the problem of the creation of the Depositary of the main viruses affecting agricultural and forest crops, and scientific center «Virus», which was initiated by the Bureau of the
The purpose. To show structure and function of pathogens of virus nature on the basis of own researches and researches carried out together with pupils-virologists and scientists of specialized laboratories of researches as well as analysis of results of studying viruses of different taxonomic groups. To present a substantiation of problems and tasks in the field of virology. Methods. Virologic, ecological, molecular and other specialized techniques in versatile experiments (electronic microscopy, IFA, PCR, culture of tissues, mathematical modelling, etc.). Results. Screening of virus infections of various organisms is made. On separate modelling systems it is opened nocuity of causal organisms of diseases and their modern molecular-biological properties, ubiquity. Viruses also are considered as vector systems of transfer of biological information in technologies of different levels of complexity. Problems with virus infections in agrarian and industrial complex, as well as virologic situations on state level are presented. Conclusions. At the state level it is necessary to change the attitude to development of virologic researches. Control of virus infections, their diagnostics and prophylaxis demand highly skilled experts, modern understanding of the role of viruses in nature, health protection, agriculture, defensive industry.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
