Phylogenetic reconstruction of Panulirus ornatus nuclear receptors, verified by the inclusion of respective orthologs from Drosophila melanogaster (Dr) and Daphnia magna (Da). Phylogenetic relationship was inferred using the maximum likelihood method based on the JTT matrix-based model [19], supported by bootstrap analysis with 500 replicates; the number adjacent to each node describes the percentage of trees in which the node’s sub-clade recurred. The scale bar shows amino acid substitutions per site. Designated NR families are shown on the outside of the phylogram with radial colors emphasising different genes
