The understanding of genetic diversity, geographic distribution, and antigenic properties of <i>Plum pox virus</i> (PPV) is a prerequisite to improve control of sharka, the most detrimental viral disease of stone fruit crops worldwide. Forty new PPV strain C isolates were detected in sour cherry (<i>Prunus cerasus</i>) from three geographically distant (700⁻1100 km) regions of European Russia. Analysis of their 3'-terminal genomic sequences showed that nineteen isolates (47.5%) bear the D96E mut
