Intercellular communication in the fern endosymbiotic cyanobacterium Nostoc azollae [PDF]

mBio
The water fern Azolla spp. harbors as an endobiont the N2-fixing, filamentous, heterocyst-forming cyanobacterium Nostoc azollae. N. azollae provides the fern with fixed nitrogen permitting its growth in nitrogen-poor environments.

Evolution of multicellularity genes in Cyanobacteria in the lead up to the great oxidation event [PDF]

Communications Biology
Cyanobacteria, considered responsible for the Great Oxidation Event (GOE) that shaped the Earth for the evolution of complex life, are among the most morphologically diverse prokaryotic phyla.

The Role of Mre Factors and Cell Division in Peptidoglycan Growth in the Multicellular Cyanobacterium Anabaena

mBio, 2022
Bacteria in general serve two main tasks: cell growth and division. Both processes include peptidoglycan extension to allow cell expansion and to form the poles of the daughter cells, respectively.

Cytochrome c_M Is Probably a Membrane Protein Similar to the C Subunit of the Bacterial Nitric Oxide Reductase

Applied Sciences, 2021
Cytochrome cM was first described in 1994 and its sequence has been found in the genome of manifold cyanobacterial species ever since. Numerous studies have been carried out with the purpose of determining its function, but none of them has given place ...

Interactions of PatA with the Divisome during Heterocyst Differentiation in Anabaena

mSphere, 2020
The Anabaena organismic unit is a filament of communicating cells. Under conditions of nitrogen scarcity, some cells along the filament differentiate into heterocysts, which are specialized in the fixation of atmospheric N2 and provide the vegetative ...

Sustaining Rice Production through Biofertilization with N₂-Fixing Cyanobacteria

Applied Sciences, 2021
Current agricultural productivity depends on an exogenous nutrient supply to crops. This is of special relevance in cereal production, a fundamental part of the trophic chain that plays a vital role in the human diet.

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 ...

The Inorganic Nutrient Regime and the mre Genes Regulate Cell and Filament Size and Morphology in the Phototrophic Multicellular Bacterium Anabaena

mSphere, 2020
The model cyanobacterium Anabaena sp. PCC 7120 exhibits a phototrophic metabolism relying on oxygenic photosynthesis and a complex morphology. The organismic unit is a filament of communicated cells that may include cells specialized in different ...

The Nitrogen Stress-Repressed sRNA NsrR1 Regulates Expression of all1871, a Gene Required for Diazotrophic Growth in Nostoc sp. PCC 7120

Life, 2020
Small regulatory RNAs (sRNAs) are post-transcriptional regulators of bacterial gene expression. In cyanobacteria, the responses to nitrogen availability, that are mostly controlled at the transcriptional level by NtcA, involve also at least two small ...
