Heterocyst differentiation that occurs in some filamentous cyanobacteria, such as Anabaena
sp. PCC 7120, provides a unique model for prokaryotic developmental biology. Heterocyst …

Cyanobacteria carry out oxygenic photosynthesis, play a key role in the cycling of carbon
and nitrogen in the biosphere, and have had a large impact on the evolution of life and the …

Filamentous, heterocyst-forming cyanobacteria are among the simplest multicellular systems
in Nature. In the absence of combined nitrogen, the filaments consist of vegetative cells that …

Multicellular lifestyle requires cell-cell connections. In multicellular cyanobacteria, septal
junctions enable molecular exchange between sister cells and are required for cellular …

Heterocyst-forming cyanobacteria are multicellular organisms that grow as chains of cells
(filaments or trichomes) in which the cells exchange regulators and nutrients. In this article …

Filamentous cyanobacteria have developed a strategy to perform incompatible processes in
one filament by differentiating specialized cell types, N2-fixing heterocysts and CO2-fixing …

Cyanobacteria were the first oxygenic photosynthetic organisms during evolution and were
ancestors of plastids. Cyanobacterial cells exhibit an extraordinary diversity in their size and …

Cells have to erect and sustain an organized and dynamically adaptable structure for an
efficient mode of operation that allows drastic morphological changes during cell growth and …

In filamentous heterocyst-forming (N2-fixing) cyanobacteria, septal junctions join adjacent
cells, mediating intercellular communication, and are thought to traverse the septal …

Cytochrome c 6 is a soluble electron carrier, present in all known cyanobacteria, that has
been replaced by plastocyanin in plants. Despite their high structural differences, both …
