CRP-cAMP mediates silencing of Salmonella virulence at the post-transcriptional level [PDF]

, 2018
Invasion of epithelial cells by Salmonella enterica requires expression of genes located in the pathogenicity island I (SPI-1). The expression of SPI-1 genes is very tightly regulated and activated only under specific conditions.

sRNA-mediated activation of gene expression by inhibition of 5'-3’ exonucleolytic mRNA degradation

eLife, 2017
Post-transcriptional control by small regulatory RNA (sRNA) is critical for rapid adaptive processes. sRNAs can directly modulate mRNA degradation in Proteobacteria without interfering with translation.

Isolation, identification, and pathogenic potential of Bacillus cereus from diseased big‐belly seahorse Hippocampus abdominalis

Journal of the World Aquaculture Society, Volume 57, Issue 1, February 2026.
Abstract Members of Bacillus cereus have been documented as important bacterial pathogens in aquaculture. However, scarce information is available on B. cereus isolates as causal pathogens of big‐belly seahorses Hippocampus abdominalis. In the present study, a B. cereus isolate (SH1), recovered from a disease outbreak on a seahorse farm, was identified

The green tea polyphenol EGCG inhibits E. coli biofilm formation by impairing amyloid curli fibre assembly and downregulating the biofilm regulator CsgD via the σE‐dependent sRNA RybB

Molecular Microbiology, 2016
In bacterial biofilms, which are often involved in chronic infections, cells are surrounded by a self‐produced extracellular matrix that contains amyloid fibres, exopolysaccharides and other biopolymers.

The FsrA‐Mediated Iron‐Sparing Response Regulates the Biosynthesis of the Epipeptide EPE in Bacillus subtilis

Molecular Microbiology, Volume 125, Issue 2, Page 108-122, February 2026.
Under iron‐limited conditions, FsrA base‐pairs with the intergenic region between epeX and epeE, enhancing epeE translation and triggering EPE production. Toxin‐mediated cell lysis releases nutrients, including iron, which can be taken up by surviving cells.

Temperature-dependent sRNA transcriptome of the Lyme disease spirochete

BMC Genomics, 2017
Transmission of Borrelia burgdorferi from its tick vector to a vertebrate host requires extensive reprogramming of gene expression. Small regulatory RNAs (sRNA) have emerged in the last decade as important regulators of bacterial gene expression. Despite

Genomic and Effector‐Based Insights Into Austropuccinia psidii–Host Interactions Informing RNAi and Resistance Development

Molecular Plant Pathology, Volume 27, Issue 2, February 2026.
Genomic and effector‐based insights into Austropuccinia psidii—host interactions are informing RNAi treatments and aiding resistance development for myrtle rust disease. ABSTRACT Austropuccinia psidii is a biotrophic basidiomycete and the causal pathogen of myrtle rust.

Identification of four novel small non-coding RNAs from Xanthomonas campestris pathovar campestris

BMC Genomics, 2010
Background In bacteria, small non-coding RNAs (sRNAs) have been recognized as important regulators of various cellular processes. Approximately 200 bacterial sRNAs in total have been reported.
