| Research Abstract |
The molecular phylogenetic analysis of 276 genotypes of Microcystis aeruginosa clearly showed that M. aeruginosa composed of 11 intraspecific, genetic groups (A-K). Since Japanese strains and the ASEAN strains were intermingled in the 11 clusters, it is possible that the moving of M. aeruginosa frequently occurs between these countries. From PC-IGS analysis of 30strains of Cylindrospermopsis raciborskii, it was found that C. raciborskii composed of the four different clusters which were geographically differentiated into Australia-ASEAN, East Asia, Europe, and American groups, respectively.
