Fig. 1. Phylogenetic tree based on G6 (A) and G10 (B) VP7 complete nucleotide sequences. Sequence alignments and clustering were performed using ClustalW in MEGA 7.0 software. The tree was constructed with the maximum likelihood method, with bootstrap values calculated for 1000 replicates. ▴ represents the VP7 gene of dairy calf BoRVA strains from this study (GenBank no. MN928482-MN928498; GenBank no. MN937499-MN937501); ∘ represents the VP7 gene of two yak G6 BoRVA strains; • represents the VP7 gene of BoRVA strains in China.
