Phylogenetic tree of cyanobacteria based on 16S rRNA gene sequences. The phylogenetic tree was constructed by using neighbor-joining, maximum parsimony, and maximum likelihood methods using 1,000 bootstraps. Strains producing anabaenolysins are marked according to the main variant produced: blue (anabaenolysin A), red (anabaenolysin B), and green (anabaenolysin C).
