Microcystis wesenbergii (Komárek) Komárek in Kondrateva, a major bloom forming cyanobacterial species, possesses unique colonial characteristics which can be easily distinguished from other Microcystis species. However, there is still no genetic marker to effectively characterize M. wesenbergii. In this research, thirteen strains of M. wesenbergii, collected from eight locations in Chinese water bodies were examined for molecular characterization of both cpcBA-IGS sequences (phycocyanin intergenic spacer and flanking regions) and ITS sequences (internal transcribed spacer region between 16S and 23S rDNA). The phylogenetic analysis based on cpcBA-IGS sequences showed that the M. wesenbergii strains formed a distinct cluster with high support values, indicating the cpcBA-IGS region could be used to characterize and distinguish M. wesenbergii from other species of Microcystis. These developed primers were verified to be effective in distinguishing M. wesenbergii from other species of Microcystis and from other species in different genera of cyanobacteria.
