Taxonomic History and State of Knowledge of the Marine Species in Nostocales (Cyanoprokaryote) From the Mexican Atlantic [PDF]

Ecology and Evolution
Cyanoprokaryotes are organisms that perform oxygenic photosynthesis. One of the most diverse orders is Nostocales, whose species are characterized by the presence of heterocytes.

Unexpected Genetic Diversity of Nostocales (Cyanobacteria) Isolated from the Phyllosphere of the Laurel Forests in the Canary Islands (Spain) [PDF]

Microorganisms
A total of 96 strains of Nostocales (Cyanobacteria) were established from the phyllosphere of the laurel forests in the Canary Islands (Spain) and the Azores (Portugal) using enrichment media lacking combined nitrogen.

Hapalosiphonacean cyanobacteria (Nostocales) thrived amid emerging embryophytes in an early Devonian (407-million-year-old) landscape [PDF]

iScience, 2023
Summary: Cyanobacteria have a long evolutionary history, well documented in marine rocks. They are also abundant and diverse in terrestrial environments; however, although phylogenies suggest that the group colonized land early in its history ...

Akinete formation under nitrogen limitation in an invasive cyanobacterium [PDF]

Frontiers in Microbiology
Invasive species are a global problem threatening the function of ecosystems. Besides prominent species, microbial invaders are considered as “invisible” and have spread over almost all continents.

First observation of genus Komarkiella in Iranian saline soils [PDF]

Scientific Reports
Cyanobacteria are key elements of saline soils, particularly in the formation of vast surface crusts in arid regions and mine spoil wastes. These microorganisms are also abundant in areas that subjected to periodic wetting and submergence.

Analysis of gut microbiota in rheumatoid arthritis patients. Disease-related dysbiosis and modifications induced by etanercept [PDF]

, 2018
A certain number of studies were carried out to address the question of how dysbiosis could affect the onset and development of rheumatoid arthritis (RA), but little is known about the reciprocal influence between microbiota composition and ...

Cylindrospermopsin: A Decade of Progress on Bioaccumulation Research

Marine Drugs, 2010
Cylindrospermopsin (CYN) is rapidly being recognised as one of the most globally important of the freshwater algal toxins. The ever-expanding distribution of CYN producers into temperate zones is heightening concern that this toxin will represent serious
