Fig. 3.

Phylogenetic relationships of three protein sequences (NS1, NP1, VP1) encoded by ORFs of bocaviruses. Phylogenetic trees of NS1 (a), NP1 (b) and VP1 (c) based on amino acid sequences were constructed by MEGA ver. 4.1 software (neighbor-joining method with 1,000 bootstrap replicates). PBoV3C is labeled with a black circle. MVC, minute virus of canines; BPV, bovine parvovirus; HBoV, human bocavirus; PBoV-WUH1, porcine boca-like virus; 6 V/7 V, partial Chinese porcine bocavirus sequences; GBoV, gorilla bocavirus; CslBoV, California sea lion bocavirus
