Figure 3.
An unrooted phylogenetic tree constructed using the maximum likelihood method based on analyzed Polish peach latent mosaic viroid isolates and selected sequences available in GenBank Isolates are described by Acc. No., host plant, and country of origin. Isolates analyzed in this study are marked in bold. Numbers at the nodes are bootstrap values based on 1,000 repetitions. Only values above 70 are shown
