Abstract
The genetic diversity of plum pox virus strain M (PPV-M) was assessed by analyzing 28 isolates collected in 8 European countries. Two genomic fragments spanning the (Cter)P3-6K1-(Nter)CI coding region as well as the full coat protein coding region were sequenced directly from PCR products. Phylogenetic analysis showed that the geographical origin of the collected isolates was clearly associated with two different PPV-M clades. Moreover, the pattern of substitutions in the CP gene shed light on the evolutionary relationships between PPV-M and the recombinant strains PPV-Rec and PPV-T.
