Multiple Sequence Alignment of the DNA pol (DNA polymerase) gene of ten coccolithoviruses (EhVs) and five other algal viruses. The evolutionary history was inferred using the Neighbor-Joining method . The bootstrap consensus tree inferred from 1000 replicates is taken to represent the evolutionary history of the taxa analyzed . The percentage of replicate trees in which the associated taxa clustered together in the bootstrap test (1000 replicates) are shown next to the branches when greater than 50% . The evolutionary distances were computed using the Maximum Composite Likelihood method  and are in the units of the number of base substitutions per site. All positions containing gaps and missing data were eliminated from the dataset (Complete deletion option). Phylogenetic analyses were conducted in MEGA4 .
