Table 1 Analyses of the tree topologies for 18 candidates for horizontal gene transfer. Support for putative transfers between Bacteria and Archaea is shown in the B&A column, and between Aquifex and Thermotoga is shown in the A&T column. The compositional bias is listed as "strong", if both the halobacterial sequence and its nearest phylogenetic neighbor failed the test for homogeneous composition. See Materials and Methods for details on performed analyses.
