Role of diversity-generating retroelements for regulatory pathway tuning in cyanobacteria

BMC Genomics, 2020
Background Cyanobacteria maintain extensive repertoires of regulatory genes that are vital for adaptation to environmental stress. Some cyanobacterial genomes have been noted to encode diversity-generating retroelements (DGRs), which promote protein ...

Ariadnema polymorpha gen. et sp. nov. (Scytonemataceae, Cyanobacteria): A new heterocytous cyanobacterium with true and false branching from ruins in the Brazilian Atlantic Forest

Journal of Phycology, EarlyView.
Abstract A novel heterocytous Cyanobacterium, Ariadnema polymorpha gen. et sp. nov., was observed in the northern Brazilian Atlantic Forest (BAF), a globally significant biodiversity hotspot that has microbiome diversity yet to be explored. Isolated from ancient sugarcane mill ruins within the BAF, the new genus (strain CCAPE130) exhibits a unique ...

Thiamin (vitamin B1) content in phytoplankton and zooplankton in the presence of filamentous cyanobacteria

Limnology and Oceanography, 2018
Top predators in several aquatic food webs regularly display elevated reproductive failure, caused by thiamin (vitamin B1) deficiency. The reasons for these low‐thiamin levels are not understood and information about the transfer of thiamin from the ...

Identification and characterization of novel filament-forming proteins in cyanobacteria [PDF]

Scientific Reports, 2019
Abstract Filament-forming proteins in bacteria function in stabilization and localization of proteinaceous complexes and replicons; hence they are instrumental for myriad cellular processes such as cell division and growth. Here we present two novel filament-forming proteins in cyanobacteria.

A Phosphorylation‐Dependent Partner‐Switching‐Like Module Regulates a Glycosyltransferase Required for Heterocyst Polysaccharide Layer Formation in Anabaena sp. Strain PCC 7120

Molecular Microbiology, EarlyView.
The glycosyltransferase All4160 is regulated by the reversible phosphorylation of Ser74. The kinase Alr3423 phosphorylates and inactivates All4160, while the SpoIIE‐like phosphatase HenR restores its activity through dephosphorylation. A nonphosphorylatable variant of All4160 bypasses the need for HenR, which demonstrates that a phosphorylation ...

Of mice and men—The emerging oral–gut–brain axis of health and disease

Periodontology 2000, EarlyView.
Abstract Objectives Oral health's inextricable links to systemic health are highlighted by the emerging oral–gut–brain axis and other well‐known axes. There is growing evidence of a complex oral–gut–brain axis linking mouth and gut microbiomes with the central nervous system.

Structural Diversity of Bacterial Communities Associated with Bloom-Forming Freshwater Cyanobacteria Differs According to the Cyanobacterial Genus. [PDF]

PLoS ONE, 2015
The factors and processes driving cyanobacterial blooms in eutrophic freshwater ecosystems have been extensively studied in the past decade. A growing number of these studies concern the direct or indirect interactions between cyanobacteria and ...

Limited response of a spring bloom community inoculated with filamentous cyanobacteria to elevated temperature and pCO2

Botanica Marina, 2018
Temperature and CO2 levels are projected to increase in the future, with consequences for carbon and nutrient cycling in brackish environments, such as the Baltic Sea.

Exploitation of Filamentous and Picoplanktonic Cyanobacteria for Cosmetic Applications: Potential to Improve Skin Structure and Preserve Dermal Matrix Components

Marine Drugs, 2020
The use of natural products in skin care formulations gained interest as a concern for modern societies. The undesirable side effects of synthetic compounds, as well as the associated environmental hazards, have driven investigation on photosynthetic ...
