Genome-Scale Mapping of Escherichia coli σ54 Reveals Widespread, Conserved Intragenic Binding

Project description:We investigated the effect that intragenic s54 binding sites have on transcripton elongation. In an rpoN deletion we have over-expressed rpoN from a plasmid (with vector only contol) and then looked at changes in transcription elongation around intragenic s54 binding sites by RNA-seq. We are also looking at changes in transcription initiation/elongation at sites of sigma factor overlap.

Sequence Requirements for Cascade Function in a Type I-E CRISPR System: RNA-Seq

Project description:We measured global RNA levels using RNA-seq in cas3 E. coli cells with intact CRISPR arrays or cells with the CRISPR-I array deleted to determine if off-target events driven by endogenous spacers affect local gene expression.

RNA-Seq of wild type E. coli MG1655 versus those with a deletion in the hns gene (Histone-like protein H-NS)

Project description:The aim of the experiment was to determine differences in RNA levels between wild-type E. coli and E. coli with an hns deletion. We used RNA-seq, but to control for variation in sample preparation and sequencing, we combined each E. coli RNA sample with a spike-in Salmonella RNA sample of known concentration. Libraries constructed in duplicate from strains grown with and without Salmonella spike-in to assess absolute genome-wide changes in transcription.This allowed us to normalise RNA levels between samples during data analysis.

SuhB associates with Nus factors to facilitate 30S ribosome biogenesis in Escherichia coli

Project description:This experiment consists of two studies. The first where two independent biological replicates of MG1655, MG1655 thyA suhB::thyA and MG1655 thyA nusB::thyA were each grown in LB to mid-exponential phase. RNA-seq and associated data analysis were performed as described previously (Stringer et al., 2014. PMID 24272778). The second where five cultures of MG1655 thyA suhB::thyA were grown overnight from single colonies at 37 C in LB. 5 L of each overnight culture was spread on LB agar and incubated at 30 C, the non-permissive temperature for suhB mutants. One suppressor mutant colony was selected from each plate. rnc was PCR amplified from colonies using oligonucleotides JW836-JW837, and the PCR products were sequenced to identify the presence, if any, of suppressor mutations. Genomic DNA from a strain with wild-type rnc was prepared using a DNeasy Blood and Tissue Kit (Qiagen). A DNA library was prepared using a Nextera kit (Illumina). The library was sequenced (paired-end reads) using an Illumina MiSeq instrument.

Mapping the Regulatory Network for Salmonella Typhimurium Invasion

Project description:Using RNAseq, the goal of the study is to investigate transcription factor regulation of virulence genes in 14028s Salmonella Typhimurium grown in SPI-1-inducing conditions. Transcription factors were cloned into pBAD24. RNA levels were compared in 14028s Salmonella Typhimurium with the transcription factor-encoding gene deleted, carrying either empty pBAD24, or pBAD24 expressing the transcription factor corresponding to the deletion. The Transcription factors analyzed are HilA, HilC, HilD, SprB, InvF, RtsA and RtsB.

MG1655 Flagellar Regulators RNA-seq

Project description:This experiment contains RNA-seq data for a motile derivative of MG1655 and isogenic strains with deletions of each flagellar regulator: flhD, flhC, and fliA. All strains were grown at 37 degrees C in LB. After RNA purification, ribosomal RNA was removed using RiboZero and a library was made of remaining total RNA.
