Abstract
Plum pox virus (PPV), the causal agent of Sharka disease, is an important pathogen of stone fruit trees. In this study, 24 new Czech PPV isolates from five different orchards were collected and characterized, molecularly. PPV-D isolates were identified in all orchards studied; whereas PPV-Rec isolates were identified in only two of them. A phylogenetic analysis on (Cter) NIb-(Nter) CP was performed. Three Czech PPV-D isolates BOH11CZ, BOH12CZ, and BOH13CZ diverged into a significantly separated cluster. PPV-Rec isolates formed a fairly homogenous group. However, the Bohutice and the Lipov PPV-Rec isolates clustered in two significantly separated branches.
