The taxonomy of heterocystous cyanobacteria belonging to the genera Calothrix and Tolypothrix has long been a matter of debate, but their phylogenetic relationships are still not well understood. Our aim was to compare the phylogeny and morphology of members of these genera, which exhibit basal-apical polarity. A phylogeny was reconstructed on the basis of 16S rRNA gene sequences and compared with the morphological characterization of new isolates and environmental samples. Strains isolated… CONTINUE READING
