Possible pathways of cyanobacterial evolution are discussed on the basis of in silico analysis of fully sequenced genomes of 45 species/strains of cyanobacteria. The information on quantity and functions of different mobile elements (IS, MITE elements and group II introns) was reviewed. Positive correlation between whole genome sizes and number of genes, encoding transposases has been revealed. It is suggested that transpositions play significant role in genome rearrangements taking part in gene regulation and adaptation processes determining the directions of microevolution processes in cyanobacterial populations.
