Phylogeny and the dN/dS rate value of Schizothoracine fish and other four fish species. a Phylogenetic tree [38] used in present study, spotted gar as outgroup. Red and black arrows indicate decreased or increased terminal dN/dS rate value compared with the ancestral branch. b The dN/dS rate value for terminal branches were estimated from each orthologous genes. c Average dN/dS rate value of concatenated all orthologs in four fish species
