The Heterocyst-Specific NsiR1 Small RNA Is an Early Marker of Cell Differentiation in Cyanobacterial Filaments
(2014)
Differentiation of single cells along filaments of cyanobacteria constitutes one of the simplest developmental patterns in nature. In response to nitrogen deficiency, certain cells located in a semiregular pattern along ...

Heterocyst-Specific Transcription of NsiR1, a Non-Coding RNA Encoded in a Tandem Array of Direct Repeats in Cyanobacteria
(Elsevier, 2010)
In response to nitrogen deficiency, some cyanobacteria develop heterocysts, a terminally differentiated cell type, specialized for the fixation of atmospheric nitrogen. In Nostocales, this differentiation process is ...

NsrR1, a Nitrogen stress-repressed sRNA, contributes to the regulation of nblA in Nostoc sp. PCC 7120
(Frontiers Media, 2018-09-24)
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 ...

The sRNA NsiR4 is involved in nitrogen assimilation control in cyanobacteria by targeting glutamine synthetase inactivating factor IF7
(National Academy of Sciences, 2015)
Glutamine synthetase (GS), a key enzyme in biological nitrogen assimilation, is regulated in multiple ways in response to varying nitrogen sources and levels. Here we show a small regulatory RNA, NsiR4 (nitrogen stress-induced ...

Dynamics of transcriptional start site selection during nitrogen stress-induced cell differentiation in Anabaena sp. PCC7120
(National Academy of Sciences (U.S.), 2011)
The fixation of atmospheric N2 by cyanobacteria is a major source of nitrogen in the biosphere. In Nostocales, such as Anabaena, this process is spatially separated from oxygenic photosynthesis and occurs in heterocysts. ...

Identification of conserved and potentially regulatory small RNAs in heterocystous cyanobacteria
(Frontiers Media S.A., 2016)
Small RNAs (sRNAs) are a growing class of non-protein-coding transcripts that participate in the regulation of virtually every aspect of bacterial physiology. Heterocystous cyanobacteria are a group of photosynthetic ...
