Figure Lengend Snippet: Phylogenetic analysis of monkeypox (mpox) virus sequences first reported in Guangzhou, China. A) The eight local sequences (red dot) in FASTA format were aligned by the BioEdit software 7.0.9 with the reference sequences of mpox viral clade IIb downloaded from GISAID (black dot) and NCBI (NC_063383.1, green dot, selected as the outgroup). The maximum likelihood (ML) phylogenetic tree of the full-length genome sequences of mpox virus was constructed with the MEGA software 11.0.11 using the General Time Reversible model with 500 bootstrap replicates. The scale bar represents the genetic distance. Bootstrap values >75% are presented at the corresponding nodes of the tree. Abbreviations: FASTA, Fast-All; GISAID, Global Initiative on Sharing Avian Influenza Data; NCBI, National Center For Biotechnology Information. B) The analysis of amino acid mutation of the eight local sequences compared to the reference Japan|EPI ISL 17692269|2023-04-28. In most cases, the mutation sites are mixed. Only the dominant amino acid is shown. “*” represents termination codon. As for this special site, the CAG (Q) codon accounts for 29.26% of all reads, but the TAG (stop) codon accounts for 70.74%.
