PPV-CR: a new strain of Plum pox virus described from sour cherry in Russia

Until 2012, seven strains of Plum pox virus (Potyvirus – EPPO A2 list) were known:
- PPV-D (Dideron)
- PPV-M (Marcus)
- PPV-C (Cherry)
- PPV-W (Winona)
- PPV-EA (El Amar)
- PPV-Rec (recombinant between PPV-D and PPV-M)
- PPV-T (Turkey)
Recent studies have showed that PPV isolates naturally infecting sour cherry trees (Prunus cerasus) in the Samara and Saratov oblasts of the Volga Basin in Russia corresponded to a new type of strain which was called PPV-CR (PPV Cherry Russia). Affected sour cherry trees showed mid-rib yellowing on the lower leaves; chlorotic or light-green patterns as well as ring spots on leaves in the middle part of the tree; and slight spotting and leaf deformation on top leaves. This new strain is not limited to the Volga basin, as later studies detected 9 isolates of PPV-CR in the Greater Moscow area.
