| Abstract:
The diversity of PPV isolates was monitored during up to 10 years in a cluster of infected orchards. Differences between isolates were characterized by SSCP analysis and then by the coat protein gene sequence. Differences were detected both among PPV-M and PPV-D isolates. CP gene sequence allowed the clustering of PPV-D isolates into 3 types. The repartition of the isolates in the focus correlated with the type of sequences. A central parcel accommodates all types of PPV-D which were found. | |
