Phylogenetic trees of ancestral NCLDV genes involved in mRNA processing/maturation. (A). Superfamily 2 helicases homologous to Vaccinia A18. (B). Superfamily 2 helicases homologous to Vaccinia D6 and D11. (C). Capping enzyme (guanylyltransferase domain). (D). Capping enzyme (methyltransferase domain). (E). RNA ligase. Branches with bootstrap support less than 50 were collapsed. For each sequence, the species name abbreviation and the gene identification numbers are indicated; env stands for sequences retrieved from env_nr database.
