Project description:AraC is an Escherichia coli transcription factor that regulates genes in response to the presence/absence of arabinose. We used transcription profiling to determine RNA levels in Escherichia coli K-12 strain MG1655 and MG1655 delta araC grown either in the absence or the presence of arabinose. Thus, we identified known and novel AraC-regulated genes. Data presented here are raw .CEL files as well as fully analysed data using GeneSpring
Project description:We used RNA-seq to determine the effects of AraC and arabinose on RNA levels genome-wide in S. enterica. Wild-type or delta araC mutant cells were grown in both the presence and absence of 0.2% L-arabinose. RNA-Seq libraries from two independent biological replicate samples were sequenced for (i) wild-type cells with no treatment, (ii) wild-type cells treated with arabinose, (iii) delta araC cells with no treatment, (iv) delta araC cells treated with arabinose. Comparisons were made between (i) and (ii) [analysis file name: Salmonella RNA-seq processed WT without arabinose vs WT with arabinose.xls], between (i) and (iii) [analysis file name: Salmonella RNA-Seq proessed no arabinose WT vs no arabinose delta araC.xls], and between (ii) and (iv) [analysis file name: Salmonella RNA-Seq processed arabinose WT vs arabinose delta araC.xls]. All analysis files are available from https://www.ebi.ac.uk/arrayexpress/files/E-MTAB-1901/E-MTAB-1901.additional.1.zip
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.
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.
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.
Project description:We compared RNA levels in wild-type Salmonella enterica serovar Typhimurium with RNA levels in a mutant strain in which the fliA gene was deleted.
Project description:We used RNA-seq to determine differences in RNA levels between wild-type E. coli K-12 and a ΔphoB mutant, each grown in MOPS media with low phosphate (0.2 mM).

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.
