Comparative phylogenetic analysis of non-marine planktonic picocyanobacterial isolates (based on the 16S ribosomal RNA gene and the phycocyanin operon) revealed that the geographic restriction of several clades is the outcome of under-sampling or database search bias. This result supports the high dispersive potential of planktonic picocyanobacteria and emphasizes that endemic genotypes do not seem as widespread as suggested by the latest publications.
