Molecular circuit of heterocyst differentiation in cyanobacteria

Journal of Basic Microbiology, 2020
Differentiation commitment is one of the most complex mechanisms to study in biological science. One of the model systems used for understanding differentiation complexity is heterocyst development in cyanobacteria.

The Making of a Heterocyst in Cyanobacteria.

Annual Review of Microbiology, 2022
Heterocyst differentiation that occurs in some filamentous cyanobacteria, such as Anabaena sp. PCC 7120, provides a unique model for prokaryotic developmental biology. Heterocyst cells are formed in response to combined-nitrogen deprivation and possess a

HetF defines a transition point from commitment to morphogenesis during heterocyst differentiation in the cyanobacterium Anabaena sp. PCC 7120

Molecular Microbiology, 2023
The filamentous cyanobacterium Anabaena sp. PCC 7120 is able to form heterocysts for nitrogen fixation. Heterocyst differentiation is initiated by combined‐nitrogen deprivation, followed by the commitment step during which the developmental process ...

The reduction in water volume favors filamentous cyanobacteria and heterocyst production in semiarid tropical reservoirs without the influence of the N:P ratio.

Science of the Total Environment, 2021
Predictions of more frequent and intense toxic cyanobacterial blooms in the future arise due to the synergistic effects of eutrophication combined with climate change.

Heterocyst formation in cyanobacteria

Current Opinion in Microbiology, 2000
When deprived of combined nitrogen, many filamentous cyanobacteria develop a one-dimensional pattern of specialised nitrogen-fixing cells, known as heterocysts. Recent years have seen the identification and characterisation of some of the key genes and proteins involved in heterocyst development and spacing, including the positive regulator HetR and ...

Endosymbiotic heterocystous cyanobacteria synthesize different heterocyst glycolipids than free-living heterocystous cyanobacteria

Phytochemistry, 2013
The heterocysts of limnetic nitrogen-fixing filamentous cyanobacteria contain unique glycolipids in their cell wall that create the distinctive gas impermeability of the heterocyst cell wall as well as serve as biomarker lipids for these microbes.
