Neighbor-joining phylogenetic tree based on the p-distance among the nucleotide sequences of the complete genomes for PAstV. Along the branches, percentage of bootstrap values based on 10,000 replicates (only values equal or larger than 70% are shown). The filled circles identified the isolates sequenced in this research. GenBank accession number, country and year of the outbreak are also shown below the strains. The PAstV lineages referred in the text are included on the right of the tree. Scale bars indicate nucleotide substitutions per site
