First Application of IFCB High-Frequency Imaging-in-Flow Cytometry to Investigate Bloom-Forming Filamentous Cyanobacteria in the Baltic Sea

Frontiers in Marine Science, 2021
Cyanobacteria are an important part of phytoplankton communities, however, they are also known for forming massive blooms with potentially deleterious effects on recreational use, human and animal health, and ecosystem functioning.

Quantifying gliding forces of filamentous cyanobacteria by self-buckling [PDF]

eLife, 2022
Filamentous cyanobacteria are one of the oldest and today still most abundant lifeforms on earth, with manifold implications in ecology and economics. Their flexible filaments, often several hundred cells long, exhibit gliding motility in contact with ...

Persistent blooms of filamentous cyanobacteria in a cormorant-affected aquatic ecosystem: Ecological indicators and consequences

Ecological Indicators, 2021
Globally, the establishment of protected reserves contributes positively to species protection but also presents a real threat of unexpected changes. A few reports showed that progressively increasing the number of roosting and breeding cormorants across

Identification of Putative Biosynthetic Gene Clusters for Tolyporphins in Multiple Filamentous Cyanobacteria

Life, 2021
Tolyporphins A–R are unusual tetrapyrrole macrocycles produced by the non-axenic filamentous cyanobacterium HT-58-2. A putative biosynthetic gene cluster for biosynthesis of tolyporphins (here termed BGC-1) was previously identified in the genome of HT ...

Basin-specific changes in filamentous cyanobacteria community composition across four decades in the Baltic Sea

Harmful Algae, 2020
Almost every summer, dense blooms of filamentous cyanobacteria are formed in the Baltic Sea. These blooms may cause problems for tourism and ecosystem services, where surface accumulations and beach fouling are commonly occurring.

Motility in Filamentous Cyanobacteria

Annual Review of Microbiology
Filamentous cyanobacteria are multicellular organisms that perform oxygenic photosynthesis and frequently exhibit surface motility. This review discusses the underlying mechanism facilitating motility in these organisms, with a focus on recent molecular ...

Noise–Seeded Developmental Pattern Formation in Filamentous Cyanobacteria

Life, 2018
Under nitrogen-poor conditions, multicellular cyanobacteria such as Anabaena sp. PCC 7120 undergo a process of differentiation, forming nearly regular, developmental patterns of individual nitrogen-fixing cells, called heterocysts, interspersed between ...

A Model of Filamentous Cyanobacteria Leading to Reticulate Pattern Formation

Life, 2014
The filamentous cyanobacterium, Pseudanabaena, has been shown to produce reticulate patterns that are thought to be the result of its gliding motility. Similar fossilized structures found in the geological record constitute some of the earliest signs of ...

Structural mechanics of filamentous cyanobacteria [PDF]

Journal of the Royal Society Interface, 2022
Filamentous cyanobacteria, forming long strands of connected cells, are one of the earliest and most successful forms of life on Earth. They exhibit self-organized behaviour, forming large-scale patterns in structures like biomats and stromatolites.

The Identification of Filamentous Cyanobacteria Isolated from Neopyropia Germplasm Bank Illustrates the Pattern of Contamination

Journal of Marine Science and Engineering, 2022
The germplasm bank of economic algae provides biological insurance against environmental changes and pressures for the cultivation industry. However, the red algal free-living conchocelis germplasm of Neopyropia was easily contaminated with filamentous ...
