Fig. 7 in Five newly recorded species of cyanobacteria in Korea

Fig. 7. Maximum-Likelihood (ML) phylogenetic tree based on 16S rRNA gene sequences of Myxacorys chilensis, Tildeniella torsiva and other cyanobacterial strains. 16S rRNA gene sequences of genera (Gloeobacter violaceus PCC 7421, Pseudanabaena catenata PCC 7408) were included as the outgroups. Additionally, the probability of Bayesian analysis was incorporated into the ML tree to support the strength of each branch. The first and second numbers at the nodes display the bootstrap proportions (>50%) in ML and posterior probabilities (>0.50) in Bayesian analysis, respectively. The branch lengths are proportional to the scale given.
