TL;DR: It is shown that the conserved 5′ end of RybB sRNA recognizes multiple mRNAs of Salmonella outer membrane proteins by ≥7-bp Watson–Crick pairing, and is sufficient to guide target mRNA degradation and maintain σE-dependent envelope homeostasis.

TL;DR: The classic MicF sRNA is assigned to the growing class of Hfq‐associated regulators that use diverse mechanisms to impact multiple loci and targets lpxR at both the ribosome binding site and deep within the coding sequence.

TL;DR: In this article, a review of the non-coding RNA world of Salmonella is presented, which covers small RNAs (sRNAs) that act as post-transcriptional regulators of gene expression, novel Salmonellas cis-regulatory RNA elements that sense metabolite and metal ion concentrations (or temperature), and globally acting RNA-binding proteins such as CsrA or Hfq (inactivation of which cause drastic phenotypes and virulence defects).

TL;DR: The first regulatory RNA of an enterobacterial pathogenicity island is identified, and new roles for Hfq and HilD in SPI‐1 gene expression are found, and InvR represses the synthesis of the abundant OmpD porin encoded by the Salmonella core genome.

TL;DR: The finding that expression of either MicA or RybB sRNA protects the cell from the loss of viability experienced when σE activity is inadequate illustrates the importance of the posttranscriptional repression arm of the response.
