A New Porcine Reproductive and Respiratory Syndrome Virus with N-Linked Glycosylation Site Deletion in GP5 44th Amino Acid from JXA1, NADC30-Like, and JM Triparental Recombination
Figure 3
Complete genome-based (a) and GP5-based (b) phylogenetic tree of PRRSV-HQ-2020 and 123 reference PRRSV-2 strains. PRRSV-2 strains are divided into four lineages in both trees, which are shown in distinct colors. The recombinant virus PRRSV-HQ-2020 was clustered into a separate branch of lineage 8 in the complete genome-based phylogenetic tree and lineage 3 in GP5-based phylogenetic tree, marked with a black star. Each virus is presented by the virus name. Scale bar = 0.1 indicates the nucleotide substitution per site.
