Life, 2020 The filamentous cyanobacterium Anabaena sp. PCC 7120 produces, during the differentiation of heterocysts, a short peptide PatS and a protein HetN, both containing an RGSGR pentapeptide essential for activity.

Dating the cyanobacterial ancestor of the chloroplast [PDF]
, 2009 Cyanobacteria have played a pivotal role in the history of life on Earth being the first organism to carry out oxygenic photosynthesis, which changed atmospheric chemistry and allowed the evolution of Eukarya.

Expanding the Direct HetR Regulon in Anabaena sp. Strain PCC 7120 [PDF]
, 2013 In response to a lack of environmental combined nitrogen, the filamentous cyanobacterium Anabaena sp. strain PCC 7120 differentiates nitrogen-fixing heterocyst cells in a periodic pattern. HetR is a transcription factor that coordinates the regulation of

Cellular Innovation of the Cyanobacterial Heterocyst by the Adaptive Loss of Plasticity.
Current Biology, 2019 Cellular innovation is central to biological diversification, yet its underlying mechanisms remain poorly understood [1]. One potential source of new cellular traits is environmentally induced phenotypic variation, or phenotypic plasticity.

Heterocyst and Nitrogenase Development in Anabaena cylindrica [PDF]
Journal of General Microbiology, 1976 The differentiation of filaments of a continuous culture of Anabaena cylindrica after removal of fixed nitrogen has been examined. Rapid development of proheterocysts (4-5 h) and mature heterocysts (14 h) in an ordered sequence was observed; the development of the latter was concomitant with the onset of nitrogenase activity. Commitment times of 2-3 h (

Environmental Microbiology, Volume 28, Issue 2, February 2026.Metatranscriptomic reads from black band disease (BBD) lesions derived from samples collected during the day and night were mapped to near‐complete BBD‐derived metagenome‐assembled genomes to profile diurnal metabolic shifts among key microbial groups. Photosynthesis genes from the cyanobacterium Roseofilum reptotaenium were highly expressed during the

Role of two NtcA-binding sites in the complex ntcA gene promoter of the heterocyst-forming cyanobacterium Anabaena sp. strain PCC 7120 [PDF]
, 2015 Anabaena sp. strain PCC 7120 is a filamentous cyanobacterium that fixes N2 in specialized cells called heterocysts, which differentiate from vegetative cells in a process that requires the nitrogen control transcription factor NtcA.

Ecological, Functional, and Phylogenetic Determinants of Cyanobacterial Biomineralisation
Environmental Microbiology Reports, Volume 18, Issue 1, February 2026.Cyanobacteria contribute to the global carbon cycle by biomineralising CO2 into solid carbonates. Unlike photosynthesis, biomineralisation is a less‐understood, multifaceted and adaptive metabolic process with significant global impact. It involves cell wall structures, genetic factors, and metabolic pathways that enable mineral formation and help ...
