NsrR1, a Nitrogen stress-repressed sRNA, contributes to the regulation of nblA in Nostoc sp. PCC 7120 [PDF]
, 2018 Small regulatory RNAs (sRNAs) are currently considered as major post-transcriptional regulators of gene expression in bacteria. The interplay between sRNAs and transcription factors leads to complex regulatory networks in which both transcription factors

Antimicrobial and Cytotoxic Activities of Biogenic Nanoparticles Produced by Cyanobacteria. [PDF]
ChembiochemThe article reviews the green synthesis of biogenic nanoparticles produced by cyanobacteria, highlighting their antimicrobial and cytotoxic properties. These nanoparticles, formed intra‐ or extracellularly, show activity against Gram‐positive and Gram‐negative bacteria as well as fungi and can induce apoptosis in tumor cells.

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 (
