First report of the complete genomic sequences of strawberry mild yellow edge virus and strawberry vein banding virus isolated in Japan


Strawberry vein banding virus (SVBV) and strawberry mild yellow edge virus (SMYEV) have caused disease in strawberries for many years in Japan, but little is known about their molecular properties. We thus determined the complete genomic sequence of an isolate of each virus from Tochigi Prefecture. A nucleotide sequence analysis showed that SVBV is closely related to Chinese isolates, whereas SMYEV is closely related to German and Argentine isolates. This is the first report describing the complete genome sequences of SVBV and SMYEV isolated in Japan. Moreover, we constructed an infectious SMYEV clone, which induced mild yellowing on inoculated strawberry plants.
