Maximum-Likelihood trees of ancestral NCLDV genes present in Pandoraviruses. A, DNA polymerase B, D5 primase-helicase. C, Poxvirus Late Transcription Factor VLTF3 like (A2L). D, A32-like packaging ATPase. Branches with bootstrap support less than 0.5 were collapsed. For individual sequences, the species name and the gene identification numbers are indicated; triangles denote multiple, collapsed sequences; env stands for environmental sequences (marine metagenome). Taxa abbreviations: c1, Asfarviridae; q2, Coccolithovirus; q3, Phaeovirus; q7, Raphidovirus.
