A Model of Filamentous Cyanobacteria Leading to Reticulate Pattern Formation [PDF]
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 ...

Diel expression dynamics in filamentous cyanobacteria [PDF]
mBioFilamentous cyanobacteria of the Nostocaceae family can differentiate into multicellular forms to adapt to environmental stresses, and members can establish symbiosis with various embryophytes.

Quantifying gliding forces of filamentous cyanobacteria by self-buckling [PDF]
eLife, 2023 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 ...

Noise–Seeded Developmental Pattern Formation in Filamentous Cyanobacteria [PDF]
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 ...

Structural mechanics of filamentous cyanobacteria. [PDF]
J R Soc Interface, 2022 Abstract 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 mechanical properties of these rigid structures have contributed to their

Identification of a morphogene required for tapered filament termini in filamentous cyanobacteria. [PDF]
Microbiology (Reading), 2023 Although the photosynthetic cyanobacteria are monophyletic, they exhibit substantial morphological diversity across species, and even within an individual species due to phenotypic plasticity in response to life cycles and environmental signals. This is particularly prominent among the multicellular filamentous cyanobacteria. One example of this is the

Hormogonium Development and Motility in Filamentous Cyanobacteria. [PDF]
Appl Environ Microbiol, 2023 Filamentous cyanobacteria exhibit some of the greatest developmental complexity observed in the prokaryotic domain. This includes the ability to differentiate nitrogen-fixing cells known as heterocysts, spore-like akinetes, and hormogonia, which are specialized motile filaments capable of gliding on solid surfaces.

Identification of Putative Biosynthetic Gene Clusters for Tolyporphins in Multiple Filamentous Cyanobacteria [PDF]
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 ...

The importance of filamentous cyanobacteria in the development of oxygenic photogranules. [PDF]
Sci Rep, 2017 AbstractMicroorganisms often respond to their environment by growing as densely packed communities in biofilms, flocs or granules. One major advantage of life in these aggregates is the retention of its community in an ecosystem despite flowing water.

ON THE DOMINANCE OF FILAMENTOUS CYANOBACTERIA IN SHALLOW, TURBID LAKES [PDF]
Ecology, 1997 The phytoplankton community of eutrophic shallow lakes is often dominated by filamentous cyanobacteria of the family Oscillatoriaceae. In this paper we follow two independent approaches to show that this situation is likely to be one of two alternative stable states of the algal community.
