Figure. Phylogenetic tree of Senecavirus A P1 sequences. Maximum-likelihood analysis in combination with 1,000 bootstrap replicates as implemented in MEGA 6.06 (http://www.megasoftware.net) was used to derive the tree on the basis of nucleotide sequences. GenBank accession numbers are shown in parentheses. SVV in some isolate names indicates Seneca Valley virus, the original name for Senecavirus A. Scale bar indicates number of nucleotide changes per site.
