Shared and unique orthogroups between transcriptome assemblies. a Shared orthogroups between blood transcriptomes from four species of marine turtles, hawksbill (E. imbricata), loggerhead (C. caretta), green (C. mydas), and leatherback (D. coriacea). Red represents a “core set” of orthogroups represented in all species and blue represents orthogroups shared among all hardshell species. The cladogram on the left represents the phylogenetic relationships between these species as reported by Duchene et al. ([31]; note that branch lengths depicted are representative of relative relationships only, and not drawn to scale to represent estimated divergence times). b orthogroups shared between four leatherback tissues (ovary, brain, blood, and lung). Red represents orthogroups shared between all four tissues and blue represents orthogroups present in tissue combinations that include blood
