Heterocyst‐forming cyanobacteria are filamentous organisms that perform oxygenic
photosynthesis and CO2 fixation in vegetative cells and nitrogen fixation in heterocysts …

Cyanobacteria are prokaryotes that obtain their energy from photosynthesis, using the same
photosystem that is used by plants. They live in diverse environments that are often low in …

Some cyanobacteria are able to reduce atmospheric dinitrogen to ammonia—a process
where oxygen evolved by photosynthetic activity in the same cell is detrimental to nitrogen …

Many filamentous nitrogen-fixing cyanobacteria protect nitrogenase from oxygen in
differentiated cells called heterocysts. Heterocyst development is controlled by the …

A heterocyst is a terminally differentiated cell of cyanobacteria which is specialized in
dinitrogen fixation. Heterocyst differentiation in Anabaena sp. strain PCC 7120 is triggered …

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

In the filamentous cyanobacterium Anabaena sp. strain PCC 7120, a starvation of combined
nitrogen induces differentiation of heterocysts, cells specialized in nitrogen fixation. How do …

N2 fixation is an O2‐sensitive process and some filamentous diazotrophic cyanobacteria
that grow performing oxygenic photosynthesis confine their N2 fixation machinery to …

In Anabaena sp. strain PCC 7120, differentiation of heterocysts takes place in response to
the external cue of combined nitrogen deprivation, allowing the organism to fix atmospheric …

The heterocyst is a specialized cell for nitrogen fixation in the filamentous cyanobacteria,
and its development is triggered by limitation of combined nitrogen in the medium. During …
