[Retracted] The Genomic and Pathogenic Characteristics of the Highly Pathogenic Porcine Reproductive and Respiratory Syndrome Virus Isolate WUH2

Figure 4

Phylogenetic tree of WUH2 and Chinese PRRSV isolates based on the complete genomic sequences. The phylogenetic tree was generated by the distance-based neighbor-joining method using the MEGA3.1 software. Bootstrap values were calculated on 1000 replicates of the alignment. The different subgenotypes are indicated by different colors. The different representative PRRSV isolates were marked with the triangle
