Figure 4. The baculovirus ptp gene was presumably acquired from a lepidopteran host by an ancestral NPV.

Bayesian phylogeny of ptp nucleotide sequences from diverse invertebrate taxa. GenBank and Butterflybase/InsectaCentral accession numbers are given in Table S2. Numbers in bold indicate maximum likelihood bootstrap values based on 100 replicates, while plain numbers depict Bayesian posterior probabilities. Only values ≥50 are indicated for both analyses. The bar at the bottom indicates a branch length of 10% distance.
