Manuela Filippini Cattani, Dr. Miroslav Svercel and Valentina Rossetti for helpful comments on various versions of the manuscript. Electronic supplementary material Additional file 1: Identified gene copies. The sheet contains Information on 41 gene copies and their presence in 22 cyanobacterial species. Amino acid sequences of the coded proteins exhibit 98% similarity within a genome and 50% across species. (PDF 59 KB) Additional file 2: 16S rRNA

gene copy data including data from the rrndb-database. Table with information on 16S rRNA copy numbers including data received from the rrnDB database [45] marked (*). (PDF 30 KB) Additional file 3: Distribution of 16S rRNA copy numbers using additional data from rrndb3. Boxplot representations https://www.selleckchem.com/products/lazertinib-yh25448-gns-1480.html of the 16S rRNA gene copy number distribution across the previously defined morphological groups. NCT-501 Additional data on 16S rRNA copy numbers were received from the rrndb-database [45]. Spearman’s rank correlation coefficient (ρ) and Pearson’s correlation coefficient (R) are displayed above the graph. A strong correlation of 16S rRNA gene copies to terminally differentiated cyanobacteria is supported. (PDF 82 KB) Additional file 4: Distribution of mean distances within

species of bootstrap GM6001 ic50 samples for the different eubacterial phyla. The distribution of mean distances of the bootstrap samples presented as a histogram. The 95% confidence intervals between cyanobacteria and Chloroflexi, Spirochaetes and Bacteroidetes do not overlap. Cyanobacterial 16S rRNA gene sequence variation within species is significantly lower. (PDF 117 KB) Additional file 5: Distribution of mean distances between species of bootstrap samples for the different eubacterial phyla. The distribution of mean distances of the bootstrap samples presented as a histogram. The 95% confidence intervals between cyanobacteria and the other eubacterial phyla do not overlap. Cyanobacterial 16S rRNA gene sequence

variation between species are significantly lower. (PDF before 105 KB) Additional file 6: Phylogenetic tree and distance matrix of Spirochaetes. (A) Phylogenetic tree of the eubacterial phylum Spirochaetes including all 16S rRNA gene copies, reconstructed using Bayesian analysis. On the nodes posterior probabilities >0.90 are displayed. The letter “R” denote gene copies that are positioned on the reverse DNA strand. (B) Distance matrix of Spirochaetes. Genetic distances have been estimated according to the K80 substitution model. White lines separate sequence copies of different species. (PDF 698 KB) Additional file 7: Phylogenetic tree of Bacteroidetes. Phylogenetic tree of the eubacterial phylum Bacteroidetes including all 16S rRNA gene copies, reconstructed using Bayesian analysis. On the nodes posterior probabilities >0.90 are displayed.The letter “R” denote gene copies that are positioned on the reverse DNA strand.
