Development of Leptolyngbya sp. BL0902 into a model organism for synthetic biological research in filamentous cyanobacteria

Frontiers in Microbiology
Cyanobacteria have great potential in CO2-based bio-manufacturing and synthetic biological studies. The filamentous cyanobacterium, Leptolyngbya sp. strain BL0902, is comparable to Arthrospira (Spirulina) platensis in commercial-scale cultivation while ...

Variable selection pressures across lineages in Trichodesmium and related cyanobacteria based on the heterocyst differentiation protein gene hetR

, 2005
Due to the irreversible inhibition of nitrogenase by O2, N2 fixation is incompatible with the oxygenic photosynthesis of cyanobacteria. These organisms have therefore evolved various strategies for growing diazotrophically.

Response of a wild type and a non-nitrogen-fixing mutant of Anabaena doliolum towards different amino acids

, 1981
The effects of various amino acids on growth and heterocyst differentiation have been studied on wild type and a heterocystous, non-nitrogen-fixing (het+nif-) mutant of Anabaena doliolum.

Basic regulatory network leading to heterocyst differentiation.

, 2018
In response to combined nitrogen deprivation, the NtcA protein is activated, leading to activation of expression of HetR in some cells. NtcA and HetR undergo mutual amplification, resulting in increased levels of the two regulators.

Nitrogen fixation by a Bangladesh deepwater rice-field calothrix [PDF]

, 1990
In order to study the influence on blue-green algal nitrogenase activity of environmental variables in deepwater rice-fields (DWR), a laboratory study was planned on a DWR isolate of Calothrix (D764).

Immobilization caused physiological and biochemical changes in NaCl-resistant (NaCl^r) mutant strain of diazotrophic cyanobacterium Anabaena variabilis

, 1999
696-700Growth (in term of μ and G), heterocyst differentiation, nitrogenase activity, ammonia production, ammonia uptake, glutamine synthetase (GS) activity, 14CO2 -fixation and Hill activity have been studied in the wild-type Anabaena variabilis ...
