Phylogenetic analysis of Bma-RXR and related nuclear receptor sequences.
Maximum Likelihood tree of Bma-RXR and related nuclear receptors (NR2B group). The alignment with gaps includes 514 sites. Numbers at key nodes are aLRT support out of 1000 replicates. Bma-RXR is indicated by the boxed label Brugia malayi. The scale bar represents amino acid substitutions per site. Vertebrate and outgroup sequences were collapsed on this figure for readability. The complete RXR tree with all branches is shown in Fig. S2.
