FIG 4.
Distribution of dN/dS values in function of dS for various categories of Melbournevirus protein-coding genes. The dN/dS values were computed from the alignments of Melbournevirus coding regions with their orthologous coding regions in Cannes 8 virus or Marseillevirus. (A) Protein of known or unknown functions; (B) proteins with or without homologs in Lausannevirus (C); core proteins versus regular proteins; (D) proteins of probable bacterial origin versus regular proteins.
