c-di-GMP Homeostasis Is Critical for Heterocyst Development in Anabaena sp. PCC 7120

Frontiers in Microbiology, 2021
c-di-GMP is a ubiquitous bacterial signal regulating various physiological process. Anabaena PCC 7120 (Anabaena) is a filamentous cyanobacterium able to form regularly-spaced heterocysts for nitrogen fixation, in response to combined-nitrogen deprivation

Relationships between the ABC-exporter HetC and peptides that regulate the spatiotemporal pattern of heterocyst distribution in Anabaena. [PDF]

PLoS ONE, 2014
In the model cyanobacterium Anabaena sp. PCC 7120, cells called heterocysts that are specialized in the fixation of atmospheric nitrogen differentiate from vegetative cells of the filament in the absence of combined nitrogen.

Heterocyst differentiation in the cyanobacterium Mastigocladus laminosus [PDF]

Journal of Bacteriology, 1984
The morphological and ultrastructural aspects of heterocyst differentiation in the branching, filamentous cyanobacterium Mastigocladus laminosus were examined with light and electron microscopy. The earliest differentiation stages involved cytoplasmic changes, including (i) rapid degradation of carboxysomes, (ii) degradation of polysaccharide granules,

Cyanobacterial cell lineage analysis of the spatiotemporal hetR expression profile during heterocyst pattern formation in Anabaena sp. PCC 7120. [PDF]

PLoS ONE, 2009
Diazotrophic heterocyst formation in the filamentous cyanobacterium, Anabaena sp. PCC 7120, is one of the simplest pattern formations known to occur in cell differentiation.

Control of phycobiliprotein proteolysis and heterocyst differentiation in Anabaena [PDF]

Journal of Bacteriology, 1980
Phycobiliprotein degradation can be initiated in cultures of the cyanobacterium Anabaena by removal of combined nitrogen from the medium. Certain strains of Anabaena differentiate cells specialized for aerobic nitrogen fixation (heterocysts) under such conditions.

Impaired cell-cell communication in the multicellular cyanobacterium Anabaena affects carbon uptake, photosynthesis, and the cell wall

iScience, 2021
Summary: Cell-cell communication is an essential attribute of multicellular organisms. The effects of perturbed communication were studied in septal protein mutants of the heterocyst-forming filamentous cyanobacterium Anabaena sp. PCC 7120 model organism.

Heterocyst Differentiation in Cylindrospermum licheniforme: Studies on the Role of Transcription [PDF]

Microbiology, 1984
Heterocysts of the cyanobacterium Cylindrospermum licheniforme occur at the ends of the filaments. These cells, specialized for aerobic N2 fixation, synchronously differentiate after the fragmentation of filaments grown in a medium free of combined nitrogen.

Functional Dissection of Genes Encoding DNA Polymerases Based on Conditional Mutants in the Heterocyst-Forming Cyanobacterium Anabaena PCC 7120

Frontiers in Microbiology, 2020
The filamentous cyanobacterium Anabaena sp. PCC 7120 develops N2-fixing heterocyst cells under condition of combined-nitrogen deprivation and constitutes an excellent model for studying cell differentiation.

The Role of MreB, MreC and MreD in the Morphology of the Diazotrophic Filament of Anabaena sp. PCC 7120

Life, 2022
The cyanobacterium Anabaena sp. PCC 7120 forms filaments of communicating cells. Under conditions of nitrogen scarcity, some cells differentiate into heterocysts, allowing the oxygen-sensitive N2-reduction system to be expressed and operated in oxic ...
