(Submitter supplied) Streptococcus pneumoniae (pneumococcus) is a major human respiratory pathogen and a leading cause of bacterial pneumonia worldwide. Small regulatory RNAs (sRNAs), which often act by post-transcriptionally regulating gene expression, have been shown to be crucial for the virulence of S. pneumoniae and other bacterial pathogens. Over 170 putative sRNAs have been identified in S. pneumoniae TIGR4 strain (serotype 4) through transcriptomic studies, and a subset of these sRNAs have been further implicated in regulating pneumococcal pathogenesis. more...

(Submitter supplied) In Staphylococcus aureus, hundreds of small regulatory or small RNAs (sRNAs) have been identified, yet this class of molecule remains poorly understood and severely understudied. sRNA genes are typically absent from genome annotation files, and as a consequence, their existence is often overlooked, particularly in global transcriptomic studies. To facilitate improved detection and analysis of sRNAs in S. more...

(Submitter supplied) Next-generation sequencing technologies have dramatically increased the rate at which new genomes are sequenced. Accordingly, automated-annotation programs have become adept at identifying and annotating protein coding regions, as well as common and conserved RNAs. Additionally, RNAseq techniques have advanced our ability to identify and annotate regulatory RNAs (sRNAs), which remain significantly understudied. more...

(Submitter supplied) Deep sequencing was implemented to study the transcriptional landscape of Mycobacterium avium TMC724. High-resolution transcriptome analysis identified the transcription start points for 652 genes. One third of these coincided with the start codons and therefore belong to leaderless transcripts, whereas the rest of the transcripts had 5' UTRs with the mean length of 83 nt. In addition, the 5' UTRs of 6 genes contained SAM-IV and Ykok types of riboswitches. more...

(Submitter supplied) In recent years, the Gram-negative bacterium Acinetobacter baumannii has garnered considerable attention for its unprecedented capacity to rapidly develop resistance to antibacterial therapeutics. This is coupled with the seemingly epidemic emergence of new hyper-virulent strains.

(Submitter supplied) We have deep sequenced the small transcriptome of Escherichia coli growing in LB and in MOPS, in exponential and stationary phase, and analyzed the resulting reads by a novel pipeline STARPA (Stable RNA Processing Product Analyzer). Our analysis reveals over 14,000 small transcripts enriched during both growth stages. RNA samples were collected from total RNA pools or from crude ribosome pools and then size selected by electrophoresis to limit the products to 20-300nt.

In this study the transcriptional response of Pseudomonas putida KT2440 to oxidative, osmotic, and membrane stress conditions at two time points was investigated via identification of differentially expressed mRNAs and sRNAs. A total of 440 small RNA transcripts were detected, where 10% correspond to previously annotated sRNAs, 40% are novel intergenic transcripts and 50% are novel transcripts antisense to annotated genes. more...

(Submitter supplied) Regulatory RNAs (sRNAs) are now considered as major players in many physiological and adaptive responses in pathogenic bacteria. sRNAs have been extensively studied in Gram-negative bacteria, but less information is available in Gram-positive pathogens. There is a spread of multidrug-resistant (MDR) opportunistic organisms, grouped as “ESKAPE” pathogens, which comprise enterococci, a leading cause of hospital-acquired infections and outbreaks with emergence of MDR isolates, especially vancomycin-resistant Enterococcus faecium (VREF). more...

(Submitter supplied) Investigation of whole genome gene expression to identify overlooked sRNAs and sORFs. Background The completion of numerous genome sequences has introduced an era of whole-genome study. However, many real genes, including small RNAs (sRNAs) and small ORFs (sORFs), are missed in genome annotation. In order to improve genome annotation, we sought to identify novel sRNAs and sORFs in Shigella, the principal etiologic agents of bacillary dysentery or shigellosis. more...

(Submitter supplied) By using a novel high-throughput method, named chemical inference of RNA structures (CIRS-seq), that uses dimethyl sulfate (DMS), and N-cyclohexyl-N'-(2-morpholinoethyl)carbodiimide metho-p-toluenesulfonate (CMCT) to modify RNA residues in single-stranded conformation within native RNA secondary structures, we investigated the structural features of mouse embryonic stem cell (ESC) transcripts. Our analysis revealed an unexpected higher structuring of the 5' and 3' untranslated regions (UTRs) compared to the coding regions, a reduced structuring at the Kozak sequence and stop codon, and a three-nucleotide periodicity across the coding region of messenger RNAs. more...
