Figure 5
Phylogenetic tree of lineage 3 ORF5 sequences constructed in MrBayes40. PRRSV 2 prototype strain VR2332 (AY150564) was used as an outgroup. Some minor clusters were collapsed for clarity. Posterior probability values supporting main nodes were shown. Geographical origin and year of isolation were indicated for each sequence. Braces indicate clades 3 A–3 G.
