Cyanobacteria are amongst the most important primary producers on the
Earth. However, the evolutionary forces driving cyanobacterial species
diversity remain largely enigmatic due to both their distinction from
macroorganisms, and an undersampling of sequenced genomes. Thus, we
present a new genome of a Synechococcus-like cyanobacterium from a novel
evolutionary lineage. Further, we analyse all existing 16S rRNA sequences
and genomes of Synechococcus-like cyanobacteria. Chronograms showed
extremely polyphyletic relationships in Synechococcus, which has not been
observed in any other cyanobacteria. Moreover, most Synechococcus lineages
bifurcated after the Great Oxidation Event, including the most abundant
marine picoplankton lineage. Quantification of horizontal gene transfer
among 70 cyanobacterial genomes revealed significant differences among
studied genomes. Horizontal gene transfer levels were not correlated with
ecology, genome size, or phenotype, but were correlated with the age of
divergence. All findings were synthetized into a novel model of
cyanobacterial evolution, characterized by serial convergence of the
features, i.e. multicellularity and ecology.
