Review of the cyanobacterial genera implying planktic species after recent taxonomic revisions according to polyphasic methods: state as of 2014

The criteria for taxonomic classification of cyanobacteria were radically changed in the last few decades after application of data obtained from EM studies and after use of phylogenetic analyses, mainly derived from molecular sequencing. These changes provided important knowledge of phylogeny of cyanobacteria, and they must be also expressed in the systematic review, usable for ecologists and experimental laboratories. This paper presents short descriptions of modern families with cyanobacterial genera containing planktic types after the latest revisions. The phylogenetic position of the main planktic genera was revised and controlled.
