The taxonomy of Aphanizomenon flos-aquae strain NH-5, a producer of cyanotoxins, was re-evaluated by comparison with six other Aphanizomenon strains using morphological characteristics and 16S rRNA gene sequences. Strain NH-5 was concluded to be improperly identified as Aph. flos-aquae based upon (1) lack of bundle formation in the trichomes, (2) location of akinetes next to heterocytes, (3) lower similarities (less than 97.5%) in the 16S rRNA gene sequences relative to Aph. flos-aquae strains… 
UNRAVELING MOLECULAR DIVERSITY AND PHYLOGENY OF APHANIZOMENON (NOSTOCALES, CYANOBACTERIA) STRAINS ISOLATED FROM CHINA 1
TLDR
It is suggested that the taxonomic revision of Aphanizomenon and Anabaena genera is required to be performed by employing multilocus sequence analysis and polyphasic studies.
MORPHOLOGICAL AND 16S rRNA GENE EVIDENCE FOR RECLASSIFICATION OF THE PARALYTIC SHELLFISH TOXIN PRODUCING APHANIZOMENON FLOS‐AQUAE LMECYA 31 AS APHANIZOMENON ISSATSCHENKOI (CYANOPHYCEAE) 1
TLDR
A taxonomic reevaluation of the paralytic shellfish toxin (saxitoxins) producing cyanobacterium Aphanizomenon flos‐aquae was done using morphology and 16S rRNA gene sequences and phylogenetic clusters support the conclusion that strain LMECYA31 should be Aph.
Assessing Taxonomic Issues with the Genera Anabaena, Aphanizomenon and Nostoc Using Morphology, 16S rRNA and efp genes
TLDR
The taxonomic and phylogenetic relationships among isolates from these three genera using 16S rRNA and bacterial elongation factor P (efp) gene sequences as well as morphological analyses confirmed the nonmonophyly of Anabaena and Aphanizomenon and demonstrated that many of the isolates were intermixed among various clades in both gene phylogenies.
Phylogenetic comparison of the cyanobacterial genera Anabaena and Aphanizomenon.
TLDR
The data suggest that the planktic Anabaena and Aphanizomenon isolates belong to the same genus, regardless of their morphological differences, and a taxonomic revision of the two genera is required.
PHYLOGENETIC CHARACTERIZATION OF NOSTOC LINCKIA AND NOSTOC PUNCTIFORME (CYANOPROKARYOTA) BASED ON cpcB-cpcA GENE SEQUENCES
TLDR
The first molecular and phylogenetic characterization of two species of the genus Nostoc - Nostoc linckia and Nostoc punctiforme based on the cpcB-IGS-cpcA locus of the phycocyanin operon is presented.
Morphological characteristics and phylogenetic relationship of Anabaena species from Lakes Dianchi and Erhai, China
TLDR
Morphological characteristics and phylogenetic relationships of seven Anabaena strains isolated from two plateau lakes, Lakes Dianchi and Erhai, were investigated and showed that these seven strains were in three groups.
Diversity of Aphanizomenon-like cyanobacteria
TLDR
The diversity of the traditional genus Aphanizomenon according to recent state of knowledge is demonstrated and the close genetic relation to planktic Anabaena is recognised.
Molecular Verification of Bloom-forming Aphanizomenon flos-aquae and Their Secondary Metabolites in the Nakdong River
TLDR
There is a low potential for the production of off-flavor metabolites and cyanotoxins in Aphanizomenon blooms in the Nakdong River, likely to minimize the risk to both water quality and public health.

TLDR
It is shown that the vegetative cells, heterocysts, and spores of Aphanizomenon flos-aquae should be classes with A. morreni Kufferath as separate taxonomic units.
Taxonomic position of three planktonic blue-green algae from the genera Aphanizomenon and Cylindrospermopsis
TLDR
The classification of t hi ::; a lga to the separntP gC'nus Cylindrospermopsis SEENAYYA et SunB A RAJU 1972 is supported and the diacritical generic feature», An(/,boenn aphanizomenoicle8, which occurs m ai nly in tropical andubtropical Asia, is most related to the genus Oylinrlrospermum.
Reinvestigation of the toxins from the blue‐green alga, Aphanizomenon flos‐aquae, by a high performance chromatographic method
TLDR
Toxic red tides due to blue green alga‐Aphanizomenon flos‐aquae are becomming common occurrence in the lakes of New Hampshire, with reactions indicating their structural similarity to toxins isolated from Gonyaulax tamarensis.
Chemotaxonomy of planktonic cyanobacteria based on non‐polar and 3‐hydroxy fatty acid composition
TLDR
The classification of 28 strains was demonstrated that the unweighted pair group method with arithmetic averages (UPGMA) dendrogram corresponded to morphological species criteria, suggesting that non‐polar fatty acid composition is a valuable chemical marker in the taxonomy of planktonic cyanobacteria.

Demonstration of a toxin from Aphanizomenon flos-aquae (L.) Ralfs.
TLDR
Preliminary studies show that the blue-green alga contains a toxin which, when released from lysed cells, operates at the membrane level, destroying excitability without alteration of the transmembrane resting potential.
