The ribonuclease E regulator RebA is essential for diazotrophic growth in the cyanobacterium Anabaena PCC 7120 [PDF]

mLife
Ribonuclease E (RNase E) is central to bacterial RNA metabolism. In cyanobacteria, its activity is inhibited by RebA, a key mechanism for controlling cell morphology.

The Heterocyst-Specific Small RNA NsiR1 Regulates the Commitment to Differentiation in Nostoc

Microbiology Spectrum, 2022
Heterocysts are specialized cells that filamentous cyanobacteria differentiate for the fixation of atmospheric nitrogen when other nitrogen sources are not available.

Distinct cell division features in Anabaena, a multicellular cyanobacterium [PDF]

Journal of Bacteriology
Filamentous cyanobacteria such as Anabaena display a distinct multicellular organization in the bacterial kingdom. In the filament, the cells share a common periplasm and continuous peptidoglycan sacculus and outer membrane.

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

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

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,

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.
