Arrow denotes a gene duplication event. In cDNA clones, only one was identified from non-teleosts, whereas two genes were identified from teleosts. The two genes differed by about 20% in amino acid sequence, and were grouped into separate clades (and ). In both clades, the gene relationships were consistent with the evolutionary relationships of teleost species [18, 19, 21]. (B) Partial-length gel images of the RT-PCR expression analysis of genes and positive control () genes in ray-finned fishes. The tree in the left panel shows the relationships among the genes inferred in this study. The black circle on the tree denotes the timing of the gene duplication event. Letters indicate tissues: M, muscle; L, liver; H, heart; Gi, gill; B, brain; K, kidney. Full-length gels, including negative controls and size markers, are presented in Additional file : Fig. S5
