| Abstract: | ThreeSynechococcus strains were isolated from seawater near the Ieodo Ocean Research Station (IORS), and their 16S rDNA genes and the internal
transcribed spacer (ITS) between the 16S and 23S rRNA genes were sequenced to investigate their phylogenetic relationships.
Phylogenetic trees based on the 16S rDNA and ITS sequences showed that they clustered in the main MC-ASynechococcus group (subcluster 5.1), but formed branches differentiating them from the described clades. As the IORS is located in an
area affected by diverse water masses, highSynechococcus diversity is expected in the area. Therefore, the IORS might be a good site to study the diversity, physiology, and distribution
of theSynechococcus group. Key words —Synechococcus, Phylogeney, 16S rRNA, ITS gene, Ieodo |
