For over 100 years, endosymbiotic theories have figured in thoughts about the differences
between prokaryotic and eukaryotic cells. More than 20 different versions of endosymbiotic …

This review summarizes recent aspects of (di) nitrogen fixation and (di) hydrogen
metabolism, with emphasis on cyanobacteria. These organisms possess several types of the …

The cyanobacterial phylum encompasses oxygenic photosynthetic prokaryotes of a great
breadth of morphologies and ecologies; they play key roles in global carbon and nitrogen …

Photosynthesis evolved in eukaryotes by the endosymbiosis of a cyanobacterium, the future
plastid, within a heterotrophic host. This primary endosymbiosis occurred in the ancestor of …

High and changing salt concentrations represent major abiotic factors limiting the growth of
microorganisms. During their long evolution, cyanobacteria have adapted to aquatic habitats …

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 …

Chloroplasts are cytoplasmic organelles and the sites of photosynthesis in eukaryotic cells.
Advances in structural biology and comparative genomics allow us to identify individual …

In eukaryotes, DNA is exchanged between endosymbiosis-derived compartments
(mitochondria and chloroplasts) and the nucleus. Organelle-to-nucleus DNA transfer …

Oxygenic photosynthesis evolved at least 2.4 Ga; all oxygenic organisms use the ribulose
bisphosphate carboxylase-oxygenase (Rubisco)–photosynthetic carbon reduction cycle …

Cyanobacteria forged two major evolutionary transitions with the invention of oxygenic
photosynthesis and the bestowal of photosynthetic lifestyle upon eukaryotes through …
