Fig. 5From: The genome of a vestimentiferan tubeworm (Ridgeia piscesae) provides insights into its adaptation to a deep-sea environmentGene tree of Hb subunits A1, A2, B1, and B2 from four vestimentiferan tubeworms. The values near the nodes are ultrafast bootstrap (UFBoot) values. Genes from R. piscesae are labeled in redBack to article page
