Mathematical study of pattern formation accompanied by heterocyst differentiation in multicellular cyanobacterium. [PDF]

Journal of Theoretical Biology, 2015
The filamentous cyanobacterium, Anabaena sp. PCC 7120, is one of the simplest models of a multicellular system showing cellular differentiation. In nitrogen-deprived culture, undifferentiated vegetative cells differentiate into heterocysts at ~10-cell intervals along the cellular filament.

Cyanoglobule lipid droplet accumulation as a stress response to nitrogen starvation in a non-N2-fixing mutant strain of Anabaena sp. PCC 7120. [PDF]

PLoS ONE
Cyanoglobules are lipid droplets of cyanobacteria that share compositional and functional features with plastoglobules of plant chloroplasts. However, their roles in stress physiology remain poorly defined, particularly in filamentous cyanobacteria. Here,

Functional dissection and evidence for intercellular transfer of the heterocyst‐differentiation PatS morphogen [PDF]

Molecular Microbiology, 2013
SummaryThe 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 inhibition elicited by the cells differentiating into heterocysts. Key to this process is the

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.

R-DeeP/TripepSVM identifies the RNA-binding OB-fold-like protein PatR as regulator of heterocyst patterning. [PDF]

Nucleic Acids Res
RNA-binding proteins (RBPs) are central components of gene regulatory networks. The differentiation of heterocysts in filamentous cyanobacteria is an example of cell differentiation in prokaryotes. Although multiple non-coding transcripts are involved in

Fluorescence spectroscopy study of heterocyst differentiation in Anabaena PCC 7120 filaments.

Microbiology, 2013
Filamentous Anabaena PCC 7120 differentiates nitrogen-fixing specialized cells called heterocysts at regular intervals following removal of combined nitrogen from the medium. Phycobiliproteins are degraded during differentiation. Heterocyst differentiation was followed at the single cell level by using confocal fluorescence microscopy.

FraH is required for reorganization of intracellular membranes during heterocyst differentiation in Anabaena sp. strain PCC 7120. [PDF]

J Bacteriol, 2011
In the filamentous, heterocyst-forming cyanobacteria, two different cell types, the CO2-fixing vegetative cells and the N2-fixing heterocysts, exchange nutrients and regulators for diazotrophic growth. In the model organism Anabaena sp.

mRNA localization and thylakoid protein biogenesis in the filamentous heterocyst-forming cyanobacterium <i>Anabaena</i> sp. PCC 7120. [PDF]

J Bacteriol
Heterocyst-forming cyanobacteria such as Anabaena (Nostoc) sp. PCC 7120 exhibit extensive remodeling of their thylakoid membranes during heterocyst differentiation.
