Gene clusters. Orthologous genes were subjected to BLASTP against seven other organisms, colored in gray and black when using Parachlamydia and Legionella proteins as queries, respectively. Genes were clustered according to their presence (gray) or absence (black) in the six related bacteria and the amoebal species, D. discoideum. The genes form 8 major groups at a height of 3 (A to H).
