Abstract
    Partial 16S ribosomal RNA sequences from five marine oscillatoriacean strains with narrow trichomes were determined by a dideoxynucleotide-termination method. A phenogram was constructed by a distance matrix method including a bootstrap analysis. In addition, a consensus tree was built using cladistic analysis. The results were largely congruent and indicate that the five strains belong to two different lineages. The first lineage groups four phycoerythrin-producing strains with the strain PCC7375 (“Phormidium ectocarpi Gomont”). The second cluster groups strain PCC7105 (“Oscillatoria williamsii Drouet”) with the previously studied strain Microcoleus 10mfx. Comparisons to morphological data are made and the taxonomic level of the separations is estimated.
