Further studies on the sour cherry strain of plum pox potyvirus
A sour cherry strain of plum pox potyvirus (PPV - EPPO A2 quarantine pest) has recently been characterized on plant material from Moldova (EPPO RS 94/143 and 96/149). Preliminary studies had suggested that the sour cherry isolate could represent a new subgroup of PPV strains. Further molecular and serological studies have confirmed that PPV-sour cherry is a prototype of a new subgroup called PPV-C which differs significantly from the D or M subgroups. In addition, aphid transmission (with Myzus persicae) of the PPV-sour cherry strain has been confirmed experimentally. Preliminary studies using molecular and serological methods have shown that the Italian sweet cherry isolate of PPV (EPPO RS 94/144) is indeed a member of the PPV-C subgroup.
