Genetic Variability and Phylogeny of Current Chinese Porcine Epidemic Diarrhea Virus Strains Based on Spike, ORF3, and Membrane Genes
Figure 1
Comprehensive analysis of S genes from current PEDV with reference strains. (a) Phylogenetic analysis based on S aa; (b) point mutations analysis of S aa; (c) hydrophobic analysis of S aa. Phylogenetic tree is constructed by the neighbor-joining method with the MEGA 4.0 program. The percentage bootstrap support (per 1000 replicates) is indicated by the values at each node. Cross asterisk indicated present isolates; triangle indicated attenuated strains; box indicated point mutations.
