Phylogenetic tree map of HBV S gene sequencing. 32 HBV genomes of eight different genotypes were sequenced by HBV S gene sequencing, and software MEGA4 was used to analyze these genomes to get the phylogenetic trees of HBV S gene sequencing. Tree Inference: [Method: Neighbor-Joining; Phylogeny Test and options: Bootstrap (1000 replicates; seed = 100000)]; Include Sites: [Gaps/Missing Data: Complete Deletion; Codon Positions: 1st+2nd+3rd]; Substitution Model: [Model: Nucleotide: Maximum Composite Likelihood; Substitutions to Include: d: Transitions + Transversions; Pattern among Lineages: Same (Homogeneous); Rates among sites: Uniform rates]
