FIELD: chemistry.
SUBSTANCE: invention relates to biotechnology and fundamental virology. Method includes obtaining chimeric virus by inserting gene of protein of icosahedral low-copy phloem-restricted virus (ILCPRV) envelope into effective viral vector based on tobamovirus RNA. After that plant is infected with obtained chimeric virus for it to multiply and accumulate in plant tissues. Finally, separation of chimeric virus from plant tissues is performed. Also described are plasmid for claimed method realisation, chimeric virus preparation, obtained by method described above, method of obtaining anti-serum to natural PLRV isolates and its application. Invention can be used in field of agriculture.
EFFECT: claimed is method for obtaining preparative quantities of viral particles, imitating virions of potato leaf roll virus (PLRV).
