FIGURE 5.

Phylogenetic tree of the packaging ATPase gene of the Varidnaviria realm, excluding Adenoviridae. The alignment has 116 sequences with 151 positions. The root of the phylogenetic tree was between the prokaryotic and eukaryotic members. The scale-bar indicates the average number of substitutions per site. The best-fit model was LG + R6, which was chosen according to Bayesian Information Criterion (BIC). Branches in black indicate both classical bootstrap and transfer bootstrap expectation (TBE) support values using 1,000 replicates are above 70%. Branches in blue indicate only one of the two support values is above 70% whereas branches in red indicate both support values are below 70%.
