FIG 3.

ML consensus trees (1,000 replicates for bootstrapping) for ORF5 sequences from genotype 2 isolates of the United States. Only bootstrap values of >65% are shown. Panels a and b represent phylogenetic trees resulting from splitting American ORF5 sequences into two segments, up to the detected recombination breakpoint (nt 1 to 153) and after the recombination breakpoint (nt 154 to 603). The red arrow indicates the recombinant strains, and the black arrow indicates the parental strain before the breakpoint.
