Fig. 1From: A comparative genomics study of neuropeptide genes in the cnidarian subclasses Hexacorallia and CerianthariaSchematic drawing showing the phylogenetic positions of the subclasses Ceriantharia, Hexacorallia and Octocorallia and the classes Hydrozoa, Cubozoa, Scyphozoa, and Staurozoa. Cnidaria are a sister group to Bilateria. The figure also shows that X1PRX2amide and GRFamide peptides are present in all testet Octocorallia, Cubozoa, Scyphozoa, and Staurozoa [34]. In the current paper, we are investigating these and other neuropeptides in Ceriantharia and Hexacorallia. Modified from [34]Back to article page
