PPV-CV: a new strain of Plum pox virus described from sour cherry in Russia
Based on biological, serological and molecular properties, the following strains of Plum pox virus (Potyvirus – EPPO A2 list) have been described:
- PPV-D (Dideron)
- PPV-M (Marcus)
- PPV-Rec (recombinant between PPV-D and PPV-M)
- PPV-C (Cherry)
- PPV-CR (Cherry Russia)
- PPV-W (Winona)
- PPV-EA (El Amar)
- PPV-T (Turkey)
- PPV-An (Ancestor*)
Recent studies have showed that PPV isolates naturally infecting sour cherry trees (Prunus cerasus) in the Republic of Tatarstan, Middle Volga region of Russia corresponded to a new type of strain which was called PPV-CV (PPV Cherry Volga).

* According to Palmisano et al. (2012): an Albanian isolate which could be the ancestor of PPV-M.
