Figure 2From: Genome-wide identification of nuclear receptor (NR) superfamily genes in the copepod Tigriopus japonicusGene phylogeny of nuclear receptors in T. japonicus and other related species. Phylogenetic distance was calculated with combined DBD-LBD amino acid sequences from T. japonicus and other species. A best-fit substitution model was established using maximum likelihood (ML) analysis supported by MEGA (ver.6.0). Numbers at nodes represent ML bootstrap support values and Bayesian posterior probabilities (=1.00). Details of model testing and parameters are provided in the Methods section. Tree is proportionally scaled, with the scale bar indicating sequence distance as number of substitutions. Species abbreviations: Ce: Caenorhabditis elegans, Dm: Drosophila melanogaster, Dp: Daphnia pulex, Dr: Danio rerio, Gg: Gallus gallus, Hs: Homo sapiens, Tj: Tigriopus japonicus, Xl: Xenopus laevis.Back to article page
