ChIP analysis unravels an exceptionally wide distribution of DNA binding sites for the NtcA transcription factor in a heterocyst-forming cyanobacterium [PDF]
, 2014 [Background] The CRP-family transcription factor NtcA, universally found in cyanobacteria, was initially discovered as a regulator operating N control.

Effect of glutamine on growth and heterocyst differentiation in the cyanobacterium Anabaena variabilis [PDF]
Journal of Bacteriology, 1986 Mutants of the cyanobacterium Anabaena variabilis that were capable of increased uptake of glutamine, as compared with that in the parental strains, were isolated. Growth of these mutants and their parental strains was measured in media containing N2, ammonia, or glutamine as a source of nitrogen.

Aquatic Conservation: Marine and Freshwater Ecosystems, Volume 35, Issue 10, October 2025.ABSTRACT In the first study on Neogoniolithon species for the Southwestern Atlantic Ocean, based on both molecular (COI‐5P, psbA and SSU rDNA) and morpho‐anatomical data, three taxa were identified for the Brazilian coast, including two new species. DNA‐based species delimitation methods distinguished Neogoniolithon crypticum sp. nov.

The heterocyst differentiation transcriptional regulator HetR of the filamentous cyanobactrium Anabaena forms tetramers and can be regulated by phosphorylation [PDF]
, 2016 Many filamentous cyanobacteria respond to the external cue of nitrogen scarcity by the differentiation of heterocysts, cells specialized in the fixation of atmospheric nitrogen in oxic environments. Heterocysts follow a spatial pattern along the filament

Environmental DNA, 2020 Epiphytes face several constraints regarding nutrient acquisition: They are disconnected from soil minerals and they have to mainly rely on nutrients leached by precipitation and microbes.

New Phytologist, Volume 247, Issue 4, Page 1805-1825, August 2025.Summary Cyanobacteria are major components of biofilms in light‐exposed environments, contributing to nutrient cycling, nitrogen fixation and global biogeochemical processes. Although nitrogen‐fixing cyanobacteria have been successfully used in biofertilization, the regulatory mechanisms underlying biofilm formation remain poorly understood.

Biological Routes for Biohydrogen Production: A Clean and Carbon‐Free Fuel
Biotechnology Journal, Volume 20, Issue 7, July 2025.Graphical Abstract and Lay Summary Biological routes for hydrogen (H2) production are mainly classified into four pathways: 1) direct bio‐photolysis, 2) indirect bio‐photolysis, 3) photo‐fermentation, and 4) dark fermentation. Of these pathways, dark fermentation produces the highest levels of H2 production.
