Review on Cyanobacterial Studies in Portugal: Current Impacts and Research Needs
Applied Sciences, 2021 Cyanobacteria have long been associated with harmful effects on humans, animals and aquatic biota. Cyanotoxins are their most toxic metabolite. This review summarizes the current research, impacts and future needs in cyanobacterial studies undertaken in ...

Subcellular Alterations Induced by Cyanotoxins in Vascular Plants—A Review
Plants, 2021 Phytotoxicity of cyanobacterial toxins has been confirmed at the subcellular level with consequences on whole plant physiological parameters and thus growth and productivity.

Phylogenomic and Pangenomic Assessment of a Mediterranean Strain of Raphidiopsis raciborskii Extends Knowledge of the Global Distribution and Characteristics of a Potentially Toxigenic Cyanobacterium. [PDF]
Environ Microbiol RepThe potentially toxigenic cyanobacterium Raphidiopsis raciborskii has spread to temperate regions and produces massive blooms. This study reports the first taxonomic and functional metagenomic assessment of a strain from the Mediterranean, thus filling a significant gap in global distribution.

Microorganisms, 2021 The escalating occurrence of toxic cyanobacterial blooms worldwide is a matter of concern. Global warming and eutrophication play a major role in the regularity of cyanobacterial blooms, which has noticeably shifted towards the predomination of toxic ...

Toxins, 2021 The review summarizes the available knowledge on toxins and their producers from rather disparate algal assemblages of aeroterrestrial, airborne and other versatile extreme environments (hot springs, deserts, ice, snow, caves, etc.) and on phycotoxins as

The toxic effects of meta-tyrosine are related to its misincorporation into the proteome and to altered metabolism in cyanobacteria. [PDF]
FEBS JThis study reveals that meta‐tyrosine (m‐Tyr), a nonproteinogenic analog of aromatic amino acids, disrupts protein synthesis and photosynthesis in cyanobacteria by being misincorporated by Phenylalanyl‐tRNA synthetase (PheRS) into essential proteins. Through molecular, biochemical, and proteomic analyses in Synechocystis, the research shows that m‐Tyr ...

Review of Cyanotoxicity Studies Based on Cell Cultures
Journal of Toxicology, 2022 Cyanotoxins (CTs) are a large and diverse group of toxins produced by the peculiar photosynthetic prokaryotes of the domain Cyanoprokaryota. Toxin-producing aquatic cyanoprokaryotes can develop in mass, causing “water blooms” or “cyanoblooms,” which may ...

Cylindrospermopsin: occurrence, methods of detection and toxicology [PDF]
Journal of Applied Microbiology, 2012 Cyanobacteria are aquatic micro-organisms that pose a great threat to aquatic ecosystems by the production of dense blooms, but most importantly by the production of secondary metabolites, namely the cyanotoxins. One of these is cylindrospermopsin (CYN), a hepatotoxic polyketide-derived alkaloid with well-known associated cases of animal mortalities ...
