Figure 1. Phylogenetic Relationships of Fully Sequenced Bacteroidetes.

Figure 1

(A) The 16S rRNA sequences were taken from a previously published alignment created using the NAST aligner [60]. A maximum-likelihood tree was generated using parameters estimated with ModelTest 3.7 and PAUP* (version 4.0b10). Terminal branch lengths are not drawn to scale.

(B) The average percent amino acid sequence identities were calculated using ClustalW alignments for the 530 sets of seven-way orthologs that include the five intestinal Bacteroidetes genomes, P. gingivalis, and Cy. hutchinsonii. B. thetaiotaomicron was used as a reference.
