Microcystis sp. has been recognized in recent years as a producer of a high number of secondary metabolites. Among these, peptides that are produced by the non-ribosomal peptide synthetase pathway often show bioactivity or are toxic to humans. The production of particular peptides is specific for individual Microcystis clones, allowing their characterization as chemotypes by analysing the peptidome. The authors studied the in situ diversity of peptides and chemotypes in Microcystis communities…

Diversity of coexisting Planktothrix (Cyanobacteria) chemotypes deduced by mass spectral analysis of microystins and other oligopeptides

18 clonal strains of Planktothrix are isolated from a single water sample from lake Maxsee near Berlin and analyzed by matrix-assisted laser desorption/ionization time-of-flight mass spectrometry, HPLC, and PCR for their production of peptides and the presence of microcystin synthetase genes.

Identification of peptide metabolites of Microcystis (Cyanobacteria) that inhibit trypsin-like activity in planktonic herbivorous Daphnia (Cladocera).

The present study underlines the potential importance of the biochemistry of cyanobacteria for the feeding ecology of a planktonic herbivore.

Seasonal shifts in chemotype composition of Microcystis sp. communities in the pelagial and the sediment of a shallow reservoir

In the course of the season the Microcystis community became significantly less diverse in the pelagic, and in November two chemotypes both of which did not contain microcystins accounted for nearly 80% of the colonies, whereas some chemotypes that never accounted for high relative abundances were encountered throughout the season.

Diversity of Peptides Produced by Nodularia spumigena from Various Geographical Regions

Liquid chromatography-tandem mass spectrometry was used to elucidate the structures of non-ribosomal peptides produced by Nodularia spumigena from the Baltic Sea, the coastal waters of southern Australia and Lake Iznik in Turkey and the results obtained were consistent with the published data on the genetic diversity of the Baltic and Australian populations.

Global Metabolomic Characterizations of Microcystis spp. Highlights Clonal Diversity in Natural Bloom-Forming Populations and Expands Metabolite Structural Diversity

To better understand the variations in cyanotoxins production between clones of the Microcystis, the diversity of several strains isolated from the same blooms, from different populations in various geographical area is investigated.

Diversity, Cyanotoxin Production, and Bioactivities of Cyanobacteria Isolated from Freshwaters of Greece

A Nostoc oryzae strain isolated from rice fields capable of producing microcystins (MCs) and a Chlorogloeopsis fritschii strains isolated from the plankton of a lake are reported, suggesting that this species may also occur in freshwater temperate habitats.

High Diversity of Microcystin Chemotypes within a Summer Bloom of the Cyanobacterium Microcystis botrys

This is the first report on microcystin chemotype variation and dynamics in M. botrys, a common bloom-former in Sweden, and it is proposed that environmental conditions may be implicated in determining their composition.



Diversity of Microcystin Genes within a Population of the Toxic Cyanobacterium Microcystis spp. in Lake Wannsee (Berlin, Germany)

It is concluded that the gene product found for most of the microcystin-producing colonies in the lake is rather unspecific and the diversity of microCystin variants in the Lake Wannsee results from activation of various amino acids during micro Cystin biosynthesis in the same genotypes.

Determination of Oligopeptide Diversity within a Natural Population of Microcystis spp. (Cyanobacteria) by Typing Single Colonies by Matrix-Assisted Laser Desorption Ionization–Time of Flight Mass Spectrometry

It could be demonstrated that the typing of single colonies by MALDI-TOF MS may be a valuable tool for ecological studies of the genus Microcystis as well as in early warning of toxic cyanobacterial blooms.

Nonribosomal peptide synthetase genes occur in most cyanobacterial genera as evidenced by their distribution in axenic strains of the PCC

Use of degenerate PCR primers, designed on the basis of conserved sequence motifs in the aminoacyl-adenylation domain of peptide synthetases, revealed the presence of the corresponding genes in the majority of the strains examined, confirmed by a screening of 146 axenic strains from the Pasteur Culture Collection of cyanobacteria.

Natural Variation in the Microcystin Synthetase Operon mcyABC and Impact on Microcystin Production in Microcystis Strains

The results suggest that recombination between imperfect repeats, gene loss, and horizontal gene transfer can explain the distribution and variation within the mcyABC operon.

Genetic diversity and phylogeny of toxic cyanobacteria determined by DNA polymorphisms within the phycocyanin locus

Phenetic and cladistic analyses of the data were used to infer the genetic relatedness and evolution of toxic and bloom-forming cyanobacteria.

rRNA sequences and evolutionary relationships among toxic and nontoxic cyanobacteria of the genus Microcystis.

The clustering of related Microcystis strains, including strains involved in the production of the cyclic peptide toxin microcystin, was consistent with cell morphology, gas vacuolation, and the low G + C contents of the genomes.

Bioactive compounds produced by cyanobacteria

The close similarity or identity in structures between cyanobacterial products and compounds isolated from sponges, tunicates and other marine invertebrates suggests the latter compounds may be derived from dietary or symbiotic blue-green algae.

Application of Real-Time PCR for Quantification of Microcystin Genotypes in a Population of the Toxic Cyanobacterium Microcystis sp

It is concluded that the mean proportion of microcystin genotypes is stable from winter to summer and that Microcystis cell numbers could be used to infer themean proportion of mcy genotypes in Lake Wannsee.

Toxic water blooms from cyanobacteria in lakes and rivers are a worldwide phenomenon. A new technique is presented for the rapid detection of toxic and nontoxic blooms. Matrix-assisted laser

Microginin FR1, a linear peptide from a water bloom of Microcystis species

The structure of microginin FR1 was identified by amino acid analysis, determination of the relative molecular mass by electrospray mass spectrometry, and by NMR to be a linear pentapeptide with a relative molecularmass of 727 which contains a β-amino-α-hydroxy-decanoic acid (Ahda), alanine, N-methyl-leucine, and two tyrosine units.
