Evolution of multicellularity genes in Cyanobacteria in the lead up to the great oxidation event [PDF]
Communications BiologyCyanobacteria, considered responsible for the Great Oxidation Event (GOE) that shaped the Earth for the evolution of complex life, are among the most morphologically diverse prokaryotic phyla.

A new family of bacterial actin-like proteins regulates cell morphology in a filamentous cyanobacterium [PDF]
mSphereActin proteins are common to all domains of life and exhibit ATP-dependent polymerization to form filaments. In bacteria, four families of bacterial actin-like proteins (BALPs) have been identified and characterized.

Harmful Algae, 2016 Summary Bloom-forming cyanobacteria Planktothrix agardhii and P. rubescens are regularly involved in the occurrence of cyanotoxin in lakes and reservoirs. Besides microcystins (MCs), which inhibit eukaryotic protein phosphatase 1 and 2A, several families

A new threat to local marine biodiversity: filamentous mats proliferating at mesophotic depths off Rapa Nui [PDF]
PeerJ, 2021 Mesophotic and deeper habitats (∼40 to 350 m in depth) around Rapa Nui (Easter Island) were investigated using a remotely operated vehicle. We observed extensive fields of filamentous cyanobacteria-like mats covering sandy substrates and mostly dead ...

npj Clean Water, 2022 Filamentous cyanobacteria have substantial niche overlap, and the causal mechanism behind their succession remains unclear. This has practical significance since several filamentous genera are the main producers of the musty odorant 2-methylisoborneol ...

Modeling filamentous cyanobacteria reveals the advantages of long and fast trichomes for optimizing light exposure. [PDF]
PLoS ONE, 2011 Cyanobacteria form a very large and diverse phylum of prokaryotes that perform oxygenic photosynthesis. Many species of cyanobacteria live colonially in long trichomes of hundreds to thousands of cells.

Journal of Phycology, 2021 Cyanobacteria classified as Microcoleus steenstrupii play a significant role as pioneers of biological soil crusts (biocrusts), but this taxon is recognized to constitute a diverse complex of strains and field populations.

Modeling cyanobacteria life cycle dynamics and historical nitrogen fixation in the Baltic Proper [PDF]
Biogeosciences, 2021 Dense blooms of filamentous diazotrophic cyanobacteria are formed every summer in the Baltic Sea. These autotrophic organisms may bypass nitrogen limitation by performing nitrogen fixation, which also governs surrounding organisms by increasing ...

Evolving interactions between diazotrophic cyanobacterium and phage mediate nitrogen release and host competitive ability [PDF]
Royal Society Open Science, 2016 Interactions between nitrogen-fixing (i.e. diazotrophic) cyanobacteria and their viruses, cyanophages, can have large-scale ecosystem effects. These effects are mediated by temporal alterations in nutrient availability in aquatic systems owing to the ...
