Differential transcriptional regulation of orthologous dps genes from two closely related heterocyst-forming cyanobacteria.
(Oxford University Press, 2015)
In cyanobacteria, DNA-binding proteins from starved cells (Dps) play an important role in the cellular response to oxidative and nutritional stresses. In this study, we have characterized the cell-type specificity and the ...

Mutual dependence of the expression of the cell differentiation regulatory protein HetR and the global nitrogen regulator NtcA during heterocyst development
(Wiley, 2002)
Heterocyst differentiation in the cyanobacterium Anabaena sp. strain PCC 7120 depends on both the global nitrogen regulator NtcA and the cell differentiation regulatory protein HetR, and induction of hetR upon nitrogen ...

The nitrogen stress-repressed srna nsrr1 regulates expression of all1871, a gene required for diazotrophic growth in nostoc sp. Pcc 7120
(Multidisciplinary Digital Publishing Institute (MDPI), 2020)
Small regulatory RNAs (sRNAs) are post-transcriptional regulators of bacterial gene expression. In cyanobacteria, the responses to nitrogen availability, that are mostly controlled at the transcriptional level by NtcA, ...

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 ...
