Figure 1From: Genome trees constructed using five different approaches suggest new major bacterial cladesDistribution of conserved gene pairs among 31 clades of prokaryotes. Closely related genomes: E. coli-Buchnera sp., H. influenzae-P. mutocida, C. trachomatis-C. pneumoniae, P. horikoshii-P. abyssi, M. genitalium-M. pneumoniae-U. urealyticum., H. pyroli – C. jejuni, T. acidophilum-T. volcanium, were treated as a single clade. Nis the total number of conserved gene pairs.Back to article page
