Phylogenetic Trees of Nuclear Receptor Subfamily 2 Groups. In this graph, each circular tree represents the corresponding color subtrees illustrated in Fig. 8. a The green circular tree represent the NR2E3 subtree, with 3 Anguilla Japonica homologs marked in red dots. b The brown circular tree represent the NR2E1 subtree, with 1 Anguilla Japonica homolog marked in red dot. c The purple circular tree represent the NR2C1 subtree, with 2 Anguilla Japonica homologs marked in red dots. d The gray circular tree represent the NR2C2 subtree, with 1 Anguilla Japonica homolog marked in red dot. e The yellow circular tree represent the NR2F2 subtree, with 3 Anguilla Japonica homologs marked in red dots. f The blue circular tree represent the NR2F6 subtree, with 2 Anguilla Japonica homologs marked in red dots. Through the analysis we found that the thyroid hormone receptor interactor family genes of Japanese eel are homologous to Asian arowana, Northern Pike, Rainbow trout, Marbled rockcod, Atlantic herring and Spotted gar
