Figure 2. Assemblage of a baculovirus DNA-dependent-DNA polymerase (DdDp or cores) maximum likelihood tree rooted at the Heliothis zea nudivirus Hz-1 (left) and a phenogram clustered with the neighbor-joining method implemented in the Weighbor program for baculovirus “core-less” genomes, i.e., without the DdDp (including satellite functions) rooted at the most distantly-related baculovirus the CuniNPV (right).

Nodes encircled by black dots indicate co-divergence events. Values near the nodes of the DdDp indicate the number of times that each tree component was observed during 500 non-parametric bootstrap maximum likelihood iterations with phyml, value between parenthesis are the posterior Bayesian probability of the node estimated with MrBayes. Nodes encircled by black dots indicate codivergence events estimated with the TreeMap program.
