Unravelling HetC as a peptidase-based ABC exporter driving functional cell differentiation in the cyanobacterium Nostoc PCC 7120 [PDF]

Microbiology Spectrum
The export of peptides or proteins is essential for a variety of important functions in bacteria. Among the diverse protein-translocation systems, peptidase-containing ABC transporters (PCAT) are involved in the maturation and export of quorum-sensing or

Spatio-temporal coherence of circadian clocks and temporal control of differentiation in Anabaena filaments [PDF]

mSystems
Circadian clock arrays in multicellular filaments of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 display remarkable spatio-temporal coherence under nitrogen-replete conditions.

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

Terminal heterocyst differentiation in the Anabaena patA mutant as a result of post-transcriptional modifications and molecular leakage

bioRxiv, 2021
The Anabaena genus is a model organism of filamentous cyanobacteria whose vegetative cells can differentiate under nitrogen-limited conditions into a type of cell called heterocyst.

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.

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.

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.
