Many multicellular cyanobacteria produce specialized nitrogen-fixing heterocysts. During
diazotrophic growth of the model organism Anabaena (Nostoc) sp. strain PCC 7120, a …

Within the wide biodiversity that is found in the bacterial world, Cyanobacteria represents a
unique phylogenetic group that is responsible for a key metabolic process in the biosphere …

Cyanobacteria were the first organisms to use oxygenic photosynthesis for converting
carbon dioxide into useful organic chemicals. However, the chemical industry has …

There are several instances of cellular differentiation in prokaryotes, including the formation
of spores in Bacillus, the fruiting bodies of Myxococcus, and the stalked cells of Caulobacter …

It is an essential and challenging task to unravel protein–protein interactions in their actual
in vivo context. Native gel systems provide a separation platform allowing the analysis of …

Starch is a biologically and commercially important polymer of glucose and is synthesized to
form starch grains (SG s) inside amyloplasts. Cereal endosperm accumulates starch to …

Filamentous, heterocyst-forming cyanobacteria are multicellular organisms in which
individual cells exchange nutrients and, presumably, regulatory molecules. Unknown …

Filamentous cyanobacteria like Anabaena sp. PCC 7120 are able to develop a specialized
cell type named heterocyst from vegetative cells in times of nitrogen starvation. Heterocyst …

Iron uptake in proteobacteria by TonB-dependent outer membrane transporters represents a
well-explored subject. In contrast, the same process has been scarcely investigated in …

Iron uptake is essential for Gram-negative bacteria including cyanobacteria. In
cyanobacteria, however, the iron demand is higher than in proteobacteria due to the function …
