Phylogenetic relationship within the Ciona GPCR set of Adhesion receptors. A phylogeny of Ciona Adhesion GPCRs shows the presence of five different paralogous clusters (group I- group V). Tree branches that support the five groups (> 75% bootstrap support) are coloured and their bootstrap values are represented. Branches that suggest gene duplication events (>98% bootstrap support) are reported with the bootstrap values in bold italics. Ciona Adhesion GPCR homologs of Human members are depicted with a '*' symbol and the GPCRs that deviate from the predicted 7TM structure are marked using a '#' symbol.
