Fig.1 Phylogenetic analysis based on the complete genome sequences of two PBoV strains CH/HNZM and PBoV-TY together with 35 reference strains. The tree was generated by the neighbor-joining method in MEGA7 software, and bootstrap values were indicated for each node from 1, 000 replicates. The two PBoV strains from the present study are marked with black solid circles, and the GenBank accession numbers are shown in parentheses.
Fig.2 Determination of potential recombination events by RDP4.39 programs (RDP, GENECONV, BOOTSCAN, MaxChi, Chimaera, SiScan and 3Seq) (P < 0.01). One putatively recombinant breakpoint was existed in GD18 (KJ755666) strain that in the VP1/2 gene and located at position 3,458 to 4,986 nt of complete genome. The analysis was performed with an RDP distance model with window size of 20.
