Maximum likelihood phylogeny of VDRs, PXRs, and CARs. Maximum likelihood phylogeny of 49 amino acid sequences of VDRs, PXRs, and CARs (see Methods for details of analysis). Numbered branch labels indicate bootstrap percentages. Node labels 'AncR1', 'AncR2', and 'AncR3' indicate ancestral nodes that were reconstructed (see Additional files 7 and 8).
