Phylogenetic and morphological evaluation of the genera Anabaena, Aphanizomenon, Trichormus and Nostoc (Nostocales, Cyanobacteria)
Original language description
This study was investigated the taxonomy of the genera Anabaena, Aphanizomenon, Nostoc and Trichormus by morphological and phylogenetic analyses of 16S rRNA gene, rpoB and rbcLX sequences. Data showed that benthic and planktic Anabaena strains were intermixed, confirmed that Anabaena and Aphanizomenon strains were not monophyletic, as previously demonstrated. On the basis of gene sequences, the Anabaena/Aphanizomenon strains were divided into nine supported subclusters which could also be separated morphologically, and which might represent different species. Trichormus strains were morphologically and phylogenetically heterogeneous and did not form a monophyletic cluster. Nostoc strains were heterogeneous and seemed to form a monophyletic cluster, which may contain more than one genus. This study with fresh isolates showed that the current classification of these anabaenoid genera needs to be revised.

Czech description
Cílem práce bylo studovat taxonomii rodu Anabaena, Aphanizomenon, Nostoc a Trichormus morfologicky a fylogenetickými analýzami genů pro 16SrRNA, rpoB a rbcLX. Data ukázala, že bentické a planktonní rody Anabaena jsou promíchány a netvoří oddělené fylogenetické klastry, potvrdila, že rody Anabaena a Aphanizomenon nejsou monofyletické, jak se dříve předpokládalo. Dále se ukázalo, že rod Trichormus je heterogenní a netvoří monofyletický klastr. Naopak rod Nostoc tvoří monofyletickou skupinu, která může obsahovat víc rodů než jeden. Závěr práce je, že současná klasifikace heterocytózních sinic z řádu Nostocales potřebuje revizi.
