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 ...

Life, 2020 The filamentous cyanobacterium Anabaena sp. PCC 7120 produces, during the differentiation of heterocysts, a short peptide PatS and a protein HetN, both containing an RGSGR pentapeptide essential for activity.

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.

Directional RNA deep sequencing sheds new light on the transcriptional response of Anabaena sp strain PCC 7120 to combined-nitrogen deprivation [PDF]
, 2011 Background: Cyanobacteria are potential sources of renewable chemicals and biofuels and serve as model organisms for bacterial photosynthesis, nitrogen fixation, and responses to environmental changes. Anabaena (Nostoc) sp.

Differentiation in Nostoc muscorum: Nitrogenase Is Synthesized in Heterocysts [PDF]
Proceedings of the National Academy of Sciences, 1973 Cellular differentiation can be observed in certain filamentous blue-green algae after transfer of the cells from medium containing NH 4 + or NO 3 - to nitrogen-free medium.

HETEROCYST DIFFERENTIATION AND POLARITY IN CALOTHRIX [PDF]
New Phytologist, 1978 SUMMARYWhen grown in a nitrogen‐free medium Calothrix brevissima West has a basal heterocyst followed by a filament of cells of decreasing size. In a nitrate medium, the alga does not form heterocysts but partial polarity, i.e. tapering of the filaments, remains.

A combinatorial strategy of alternative promoter use during differentiation of a heterocystous cyanobacterium [PDF]
, 2017 Heterocystous cyanobacteria such as Nostoc sp. are filamentous photosynthetic organisms that, in response to nitrogen deficiency, undergo a differentiation process transforming certain, semi-regularly spaced cells into heterocysts, devoted to nitrogen ...

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.

Cyt c6-3: A new isoform of photosynthetic Cyt c6 exclusive to heterocyst-forming cyanobacteria [PDF]
, 2017 All known cyanobacteria contain Cyt c6, a small soluble electron carrier protein whose main function is to transfer electrons from the Cyt b6 f complex to PSI, although it is also involved in respiration.
