Abstract:
To study phylogenetic relationships among Okinawan soft corals of the genus Clavularia, the ribosomal internal transcribed spacer sequences of host corals and the 18S rDNA sequences of symbiotic algae were analyzed. The molecular phylogenetic trees of hosts showed that a prostanoid-containing species, Clavularia viridis, is deeply diverged from other species of Clavularia which do not biosynthesize the prostanoids as the main secondary metabolites. Comparison of their trees suggested poor phylogenetic concordance between hosts and symbionts.
