RNA-seq to investigate how small RNA ncS27 in Burkholderia cenocepacia regulates uptake and metabolism of carbon compounds

ABSTRACT: Burkholderia cenocepacia small RNA ncS27 was identified by transcriptome profiling. To investigate the function of this small RNA, ncS27 was overexpressed and silenced in trans and the effect of this on the transcriptome was studied. To overexpress ncS27 it was cloned into a vector with a rhamnose inducible promoter. To silence ncS27 it was cloned into the same vector, but in reverse orientation. The vectors were then transformed into B. cenocepacia J2315, creating two mutants. The third mutant in this experiment is a vector control mutant. All three mutants were cultivated in Lennox broth to OD 0.5, then the inducer rhamnose was added. After 30 min of incubation in presence of the inducer the cells were harvested, RNA was extracted and RNA-sequencing performed.

Small non-coding sRNAs have versatile roles in regulating bacterial metabolism. Four short homologous Burkholderia cenocepacia sRNAs strongly expressed under conditions of growth arrest were recently identified. Here we report the detailed investigation of one of these, NcS27. sRNA NcS27 contains a short putative target recognition sequence, which is conserved throughout the order Burkholderiales. This sequence is the reverse complement of the Shine-Dalgarno sequence of a large num ...[more]

Transcriptomic profiling of L-rhamnose utilization in Lmo0753 deletion mutant of Listeria monocytogenes EGDe from human foodborne outbreak associated lineage LII

Project description:Among the three major genetic lineages of L. monocytogenes (i.e. LI, LII, and LIII), LI and LII are predominantly associated with foodborne listeriosis outbreaks, whereas LIII is rarely implicated in human infections. In a previous study, we identified a Crp/Fnr family transcription factor lmo0753 that was highly specific to outbreak-associated LI and LII but absent from LIII. Lmo0753 shares two conserved functional domains including a DNA-binding domain with the well-characterized master virulence regulator PrfA in L. monocytogenes. In this study, we constructed a lmo0753 deletion and complementation mutants of the fully sequenced L. monocytogenes LII strain EGDe. We found that deletion of lmo0753 led to the loss of L-rhamnose utilization in EGDe. Transcriptomic comparison of the EGDe lmo0753 deletion mutant and the wild type incubated in phenol-red medium containing L-rhamnose as the sole carbon source revealed 126 (4.5%) and 546 (19.5%) out of 2,798 genes in the EGDe genome that were up- and down-regulated for more than 2-fold, respectively. Genes involved in biotin biosynthesis, general stress response and rhamnose metabolism were shown to be differentially regulated by Lmo0753. Findings from this study may partially explain why LIII of L. monocytogenes is underrepresented in the environment and rarely associated with human listeriosis outbreaks due to the inability of rhamnose utilization. We report the transcriptomic profile of L. monocytogenes M-NM-^Tlmo0753 LII strain (EGDe) in broth media with L-rhamnose as the sole carbon source. Examination of deletion of Lmo0753 on L-rhamnose utilization in L. monocytogenes. Two biological replicates per WT and M-NM-^Tlmo0753.

BCAM0258 overexpression mutant

Project description:Burkholderia cenocepacia J2315 belongs to the ET12 lineage which has caused outbreaks among cystic fibrosis patients worldwide. Strains belonging to the ET12 lineage are characterized by the presence of the “Burkholderia cepacia epidemic strain marker” (BCESM). This marker is located on a genomic island involved in virulence, but the exact function of many genes in the BCESM region remains unknown. In the present study we investigated the function of three of these genes (BCAM0257, BCAM0258 and BCAM0259). We created overexpression mutants and performed a transcriptome analysis of the toxin (BCAM0258) overexpression mutant.

Aspergillus niger RhaR, a regulator involved in L-rhamnose release and catabolism

Project description:The genome of the filamentous fungus Aspergillus niger is rich in genes encoding pectinases, a broad class of enzymes that have been extensively studied due to their use in industrial applications. The sequencing of the A. niger genome provided more knowledge concerning the individual pectinolytic genes, but relatively little is still known about the regulatory genes involved in pectin degradation. Understanding regulation of the pectinolytic genes provides a tool to optimize the production of pectinases in this industrially important fungus. This study describes the identification and characterization of one of the activators of pectinase-encoding genes, RhaR. Inactivation of the gene encoding this regulator resulted in down-regulation of genes involved in the release and catabolism of L-rhamnose from the pectinolytic substructure rhamnogalacturonan I. We aim to discover differencial expressed genes in A.niger wild type strain N402 and M-NM-^TrhaR mutant while growing on rhamnose as carbon source. Biological duplicates were made for both strain at the growth of 2 hours, Affymetrix microarray experiments were performed on these samples.

RNA-sequencing based analysis of Listeria monocytogenes 10403S::ÎBCHL Prha-sigH and ÎBCHL Prha

Project description:In this study, RNA-seq was used to compare the transcriptomes of Listeria monocytogenes 10403S::ÎBCHL Prha-sigH and ÎBCHL Prha. RNA-seq was performed on ÎBCHL Prha-sigH and ÎBCHL Prha RNA samples representing three independent biological replicates at log phase in Brain Heart Infusion (BHI) broth under rhamnose induction. Indexed and purified cDNA libraries (6 libraries including 3 replicates for 2 strains) were loaded together onto an independent flow cell without any other samples; sequencing was carried out by running Hiseq 2500 (single-end, 150-bp per read). Reads alignment was carried out using the Burrows-Wheeler Aligner (BWA). Differential expression of genes in different strains was statistically assessed using the BaySeq method. To identify sigH-dependent promoters, a new method of moving sliding windows of 50 nt along the whole genome was used to compare the normalized RNA-seq coverage (NRC) between the two strains. Using the standard whole gene differential expression analysis, significant upregulation of 5 genes in 4 operons was found in the sigH overexpressing strain. While with the sliding windiow analysis, 2 additional ÏH-dependent promoters were identified. Our results show that three ÏH-dependent transcritption units that encode competence proteins, including the comEABC , comGABCDEFG and coiA. Transcriptome profiles of L. monocytogenes 10403S::ÎBCHL Prha-sigH and ÎBCHL Prha were generated by deep sequencing, in triplicate, using Illumina Hiseq 2500.

RNA-seq analysis of Clostridium beijerinckii DSM 6423 at early exponential, acetogenic, and solventogenic growth phase on rhamnose compared to glucose

Project description:This experiment aim was to characterize the catabolism of L-rhamnose of Clostridium beijerinckii DSM 6423 by transcriptomic analysis, generating new insights and knowledge on utilization of L-rhamnose for production of chemicals, including Isopropanol, Butanol, Ethanol (IBE) and 1,2-propandiol. These analysis on cultures grown on L-rhamnose compared to D-glucose grown cultures showed upregulation of the L-rhamnose-related clusters and genes, and lower expression of the solventogenic genes, which was reflected in the products formed.

In vivo functional analysis of L-rhamnose metabolic pathway in Aspergillus niger: a tool to identify the potential inducer of RhaR

Project description:The genes of the non-phosphorylative L-rhamnose catabolic pathway have been identified for several yeast species. In Pichia stipitis, all L-rhamnose pathway genes are organized in a cluster, which is conserved in Aspergillus niger, except for the lra-4 ortholog (lraD). The A. niger cluster also contains the gene encoding the L-rhamnose responsive transcription factor (RhaR) that has been shown to control the expression of genes involved in L-rhamnose release and catabolism. In this paper, we confirmed the function of the first three putative L-rhamnose utilisation genes from A. niger through gene deletion. We explored the identity of the inducer of the pathway regulator (RhaR) through expression analysis of the deletion mutants grown in transfer experiments to L-rhamnose and L-rhamnonate. Reduced expression of L-rhamnose-induced genes on L-rhamnose in lraA and lraB deletion strains, but not on L-rhamnonate (the product of LraB), demonstrate that the inducer of the pathway is of L-rhamnonate or a compound downstream of it. Reduced expression of these genes in the lraC deletion strain on L-rhamnonate show that it is in fact a downstream product of L-rhamnonate. This work showed that the inducer of RhaR is beyond L-rhamnonate dehydratase (LraC) and is likely to be the 2-keto-3-L-deoxyrhamnonate.
