Project description:We mapped the genome-wide binding of C-terminally FLAG-tagged AraC in S. enterica subsp. enterica serovar Typhimurium strain 14028s using ChIP coupled with deep sequencing (ChIP-seq). We identified five putative target loci for AraC: upstream of araB/araC, araE, araJ, STM14_0178, and within sseD.
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:ra11-01_prgh - comparison between salmonella wild type 14028s and salmonella mutant prgh in arabidopsis infection. - What is the transcriptomic reprogramming after Salmonella infection, What is the importance of the T3SS in the plant infection, Are there differences in gene expression between the 2 bacterial strains? What are the functions of these genes, - Seedlings treated with S.Typhimurium 14028 WT and St 14028 prgH mutant.Mock treatment done with equal volume of MgCl2.
Project description:In this study, we have defined the NsrR regulon in Salmonella enterica sv. Typhimurium 14028s using a transcriptional microarray. Wild-type and nsrR mutant S. Typhimurium were grown aerobically to early log-phase (OD600~0.5) at 37C in LB medium. Total RNA was isolated from three independent cultures of both strains and interrogated on a PCR product array representing almost all ORFs.
Project description:Summary: Salmonella enterica serovar Typhimurium strain 14028s transcriptome response to lettuce medium (LM) and lettuce root exudates (LX) to minimal medium (MM). Purpose: Salmonella mRNA profile, when grown in different media was compared to minimal medium to reveal environment specific transcriptional changes. Methods: mRNA profiles were generated using Illumina HiSeq in triplicates. The sequences were analysed using Bowtie2 followed by Cufflinks.

Purpose: Salmonella mRNA profile, when grown in different media was compared to minimal medium to reveal environment specific transcriptional changes. Methods: mRNA profiles were generated using Illumina HiSeq in triplicates. The sequences were analysed using Bowtie2 followed by Cufflinks.
