Genetic Diversity Analysis of Genotype 2 Porcine Reproductive and Respiratory Syndrome Viruses Emerging in Recent Years in China

<table>Phylogenetic tree based on the deduced amino acid sequence of ORF3. The bootstrap consensus tree is shown. The sequence downloaded from GenBank had a suffix “ORF3.” The representative strains were labeled with “black triangle” and the vaccine strains were labeled with “black diamond.” The bootstrap values were shown close to the branches.</table>
