Phylogenetic trees of cyr genes and 16S rRNA genes. (A and B) Trees (topology based on NJ trees) constructed using data sets of 16S rrn-5 and multi-cyr genes. Trees in panels C and D (topology based on Bayesian trees) were constructed using data sets of 16S rrn-10 and cyrA. Bootstrap values above 50% were indicated in the order of ML, Bayesian, and NJ analysis at the nodes of the trees. Outgroup taxa and distantly related Oscillatoria sp. strain PCC 6506 were not shown in panels C and D. Vertical bar, C/R group, including Cylindrospermopsis and Raphidiopsis species. The dash in panel C means there are no data on this branch.
