Özet

The complete genome of plum pox virus strain T isolates from five different Prunus spp., including almond (P. dulcis) and sour cherry (P. ceracus) isolates, was fully sequenced using the primer pairs designed in this study. The five isolates were aligned with other 50 PPV-T isolates whose complete genome sequences were available in GenBank and then subjected to phylogenetic and diversity analyses. Recombination analysis showed no significant signal detected in the five newly sequenced isolates while confirming four recombinant isolates reported in a previous study. Nucleotide and amino acid phylogenetic trees clustered the tested isolates into three major groups: Balkan 1, 2, and 3. Strain T isolates shared high nucleotide and amino acid identities among them. Diversity analysis applied different parameters to found that the sequences of P3 and 6K1 genes were more conserved over other genes. In accordance, the highly variable P1 and CP genes were found to experience weaker purifying pressures, ? = 0.127 and 0.219, respectively, than other genes. The three neutrality tests gave negative values to all genes, suggesting that strain T populations have expanding or bottleneck selections. Genetic make-up of the only known sour cherry isolate is highly identical to isolates from other Prunus spp. Therefore, this study has updated our knowledge of T strain diversity in new hosts and provided a clear picture of genetic variation and host relationships.
