Figure 2

Phylogenetic tree showing pros and cons of both ortholog detection methods. We used PhyML [59] to reconstruct a maximum likelihood tree for family 4565 that groups chemotaxis proteins CheC. The table on the right summarizes the data obtained when listing the orthologs of the Archaeoglobus fulgidus (O29223_ARCFU) and the Bacillus subtilis (CHEC_BACSU) sequences respectively. Orthologs found by the RSD approach are indicated by a star, those detected with the phylogeny approach by black triangles, and those found by both methods with a chevron. All nodes are supposed to correspond to speciation events except those labeled with a black dot, which are assumed to be due to gene duplication events.
