Cyanobacteria are ancient photosynthetic organisms that under certain conditions (high temperature, eutrophication) can grow rapidly and form "cyanobacterial blooms". Very often, these blooms are accompanied by production of cyanotoxins, which in most cases are dangerous to the other organisms. Knowing the producers of cyanotoxins is of utmost importance, especially today when climate change has been shown to increase the frequency of toxic cyanobacterial blooms worldwide. The aim of the present study was to chara...

Cyanobacteria are a diverse group of photosynthetic bacteria found in a wide variety of habitats where they play crucial roles. They are one of the most morphologically diverse groups. The evolutionary relationships and the classification are poorly understood. The whole genome sequencing added a new dimension to our understanding of genomes of cyanobacteria and the genome-based phylogeny came into existence. The aim of this study was to conduct a genomic comparison of phylogenetically closely related filamentous ...
