Characterization of a Novel Far-Eastern Potato Virus Y Isolates

Potato Virus Y (PVY) isolates differed in pathogenicity and molecular properties were found in potato and wild plants in the Far East of Russia. The results of linking research of nucleotide sequence similarity and polymorphism of P1 gene region and serological and biological assays suggested that the viruses originated from a recombination and/or host adaptation events involving the ordinary type virus (PVY0) that led to development of necrotic type virus (PVYN/NTN) properties in the Far-Eastern PVY isolates.
