Synchronous Akinete Germination and Heterocyst Differentiation in Anabaena PCC 7937 and Nostoc PCC 6720

, 1987
Isolates of the filamentous cyanobacteria Anabaena PCC 7937 and Nostoc PCC 6720 were selected in which the germling extruded from the akinete coat at the single cell stage and in which heterocyst differentiation occurred at the two or three cell stage ...

Conserved symbiosis‐associated genes in the cycad Encephalartos natalensis suggest co‐option for cyanobacterial symbiosis

New Phytologist, EarlyView.
The heterocyst‐rich Encephalartos natalensis cyanobacterial zone in coralloid root suggests co‐option of conserved symbiosis‐associated genes. This figure was created in BioRender (BioRender.com/https://BioRender.com/n3qveqc). Summary Plant‐cyanobacterial symbioses have evolved independently at least four times across land plants, yet their underlying ...

The DEAD-box RNA helicase CrhB exhibits pleiotropic functions in the cyanobacterium Anabaena PCC 7120

Water Biology and Security
DEAD-box RNA helicases play critical roles in regulating RNA metabolism and gene expression in both prokaryotes and eukaryotes. In the filamentous, heterocyst-forming cyanobacterium Anabaena PCC 7120, two DEAD-box helicases, CrhB and CrhC, are present ...

Photophobotaxis of single‐celled and filamentous cyanobacteria

Photochemistry and Photobiology, EarlyView.
LED illumination from below induces central accumulation of cyanobacterial species. Abstract Phototaxis refers to an organism's movement toward a light source, while photophobotaxis involves movement into illuminated regions. Although phototaxis in cyanobacteria has been widely studied, photophobotaxis has been investigated in only a few species.

Photosynthesis regulation impacts carbon and nitrogen assimilation in the diazotrophic cyanobacterium Anabaena sp. PCC 7120

New Phytologist, Volume 251, Issue 1, Page 94-110, July 2026.
Model of intercellular functional coordination in Anabaena. Summary Diazotrophic cyanobacteria fix both atmospheric carbon (C) and nitrogen (N) into biomass, but the two assimilation pathways are not compatible. Species like Anabaena sp. PCC 7120 physically separate C and N assimilation in different cell types.

Bakteriopolis: Introducing Microbes to Society

Microbial Biotechnology, Volume 19, Issue 6, June 2026.
Bakteriopolis is a travelling exhibition that brings the invisible microbial world into public spaces. The project is accompanied by a broad communication strategy to engage diverse audiences. ABSTRACT Microorganisms, while being fundamental to life on Earth, are often associated with negative perceptions and global crises.

Functional dissection and evidence for intercellular transfer of the heterocyst-differentiation PatS morphogen

, 2013
The formation of a diazotrophic cyanobacterial filament represents a simple example of biological development. In Anabaena, a non-random pattern of one nitrogen-fixing heterocyst separated by about 10 photosynthetic vegetative cells results from lateral ...

The proteome of the heterocyst cell wall in Anabaena sp. PCC 7120 [PDF]

, 2007
Anabaena sp. PCC 7120 is a filamentous cyanobacterium that serves as a model to analyze prokaryotic cell differentiation, evolutionary development of plastids, and the regulation of nitrogen fixation.
