Figure 4

Phylogenetic tree of the 685 bp partial 16S rRNA gene from saxitoxin-producing cyanobateria. Anabaena circinalis AWQC131C and Aphanizomenon sp. NH-5 show highest similarity to each other compared to C. raciborskii T3 or L. wollei. Bootstrap confidence levels are indicated on top of each branch. Branch lengths are indicated below (nucleotide substitutions per 100 character positions). Trees were reconstructed using PhyML using a GTR+G model with 1000 bootstrap replicas. Bold type indicates known PST producers.
