Genome-wide transcription start site profiling in biofilm-grown Burkholderia cenocepacia J2315

Project description:Burkholderia cenocepacia is an opportunistic pathogenic bacterium intrinsically resistant to most antibiotics and biocides. The aim of this study is to map transcription start sites and 5'UTRs, and to discover novel non-coding small RNAs expressed in biofilms. The experimental approach used for this study is differential sequencing, where RNA samples are split into two aliquots, one of which is then treated with a 5' monophosphate-dependent exonuclease. Two separate libraries are created from exonuclease-treated and -untreated sub-samples, using illumina sequencing from the 5'end, without fractionation step and without depletion of abundant rRNAs. Transcription start sites can then be identified by comparing exonuclease-treated with untreated RNA-seq libraries.

Expression data from Burkholderia cenocepacia J2315 hfq and hfq2 mutants

Project description:Hfq proteins are RNA chaperones that play a critical role in post-transcription regulation of gene expression. Bacteria of the Burkholderia cepacia complex harbor two distinct and functional Hfq proteins, the Hfq and Hfq2. We have previously performed the functional analysis of Hfq and Hfq2 in the pathogen Burkholderia cenocepacia J2315. In order to examine the impacts of each RNA chaperone on the global transcriptome of B. cenocepacia J2315, we performed comparative transcriptome profile of mutants on the hfq and hfq2 genes, using as reference the wild-type strain. For expression profiling, over-night cultures of the Burkholderia cenocepacia J2315 wild-type strain and the isogenic mutants hfq::Tp and M-NM-^Thfq2 grown in LB medium were diluted to an initial OD640 nm of 0.25 into LB medium. Triplicate samples were cultured at 37M-BM-:C with 250 r.p.m. agitation for 16 h and RNA extracted from the three bacterial isolates.

Response of Burkholderia cenocepacia J2315 to subinhibitory concentration of chlorhexidine

Project description:Burkholderia cenocepacia J2315 was grown in LB broth with and without the presence of the desinfectant chlorhexidine in the subinhibitory concentration of 5mg/L. Four biological replicates for each control and test conditions were performed. The experiment was designed as a direct comparison with dye swap of two replicates.
