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 ...

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. ...
