Fig. 3: Maximum likelihood trees showing the phylogenetic relationship between biofilm cyanobacteria and other cyanobacteria.

a Phylogenetic tree of cyanobacterial full-length 16S rRNA genes. EMIRGE-reconstructed 16S rRNA genes from this study are indicated in bold. The tree is rooted to Escherichia coli (A14565.1). b Tree based on 88 concatenated protein markers genes. The five biofilm cyanobacterial genomes are indicated in bold. The tree is rooted to GTDB Gammaproteobacteria UBA1515 (GCA_002323935.1). Scale bars represent number of substitutions per site. Bootstrap values over 50% are shown.
