Fig 4. Phylogenetic relationship of cyanobacterium OCN074, isolated from disease lesions from Kaua‘i, to other cyanobacteria.

All 16S rRNA gene sequences from the three Kaua‘i BBD cyanobacterial isolates were identical. A phylogenetic tree was generated using the Maximum Likelihood method. The ‘*’ indicates cyanobacteria associated with BBD of Palau (*[42]) the Red Sea (**[41]), and the Florida Keys (***[43]). The tree with the highest log likelihood is shown, and 1000 bootstrap replicates were used. NCBI accession numbers are in brackets and bootstrap values are indicated at branch nodes. Scale bar represents two substitutions per 100 nucleotide positions.
