Geobacter sulfurreducens and Pseudomonas aeruginosa adapted cocultures SWATH-MS

ABSTRACT: In this study we further investigate the previously observed syntrophic interaction between Geobacter sulfurreducens and Pseudomonas aeruginosa. In early coculture establishment, two genetic variants of G. sulfurreducens emerged that were strongly selected for throughout coculture evolution. Single nucleotide polymorphism (SNP) variants occurred in fabI and tetR genes of G. sulfurreducens. The tetR variants displayed upregulation of adenylate cyclase transporter, CyaE and of RND efflux pump proteins as determined through SWATH-MS proteomics.

mBio 20200407 2

Interactions between microorganisms in mixed communities are highly complex, being either syntrophic, neutral, predatory, or competitive. Evolutionary changes can occur in the interaction dynamics between community members as they adapt to coexistence. Here, we report that the syntrophic interaction between Geobacter sulfurreducens and Pseudomonas aeruginosa coculture change in their dynamics over evolutionary time. Specifically, Geobacter sp. dominance increases with adapta ...[more]

Syntrophic coculture of Syntrophobacter fumaroxidans MPOBT and Geobacter sulfurreducens PCA

Project description:Propionate accumulation is an important bottleneck for anaerobic degradation of organic matter. We hypothesized that propionate conversion by a novel coculture of Syntrophobacter fumaroxidans and Geobacter sulfurreducens can be an alternative strategy for propionate oxidation coupled to Fe(III) reduction. In this study, we successfully cocultured S. fumaroxidans and G. sulfurreducens on propionate and Fe(III). Proteomic analyses of this coculture provided insights into the underlying mechanisms of propionate metabolism pathway and interspecies electron transfer mechanism. Our study can be further useful in understanding syntrophic propionate degradation in bioelectrochemical and anaerobic digestion systems.

small RNA-Seq showing transfer of bacterial outer membrane vesicle (OMV) sRNA to host airway epithelial cells

Project description:This study is the first to show transfer of regulatory bacterial sRNAs from bacterial OMVs to host cells. Demonstration of transfer of bacterial sRNA from Pseudomonas aeruginosa OMVs to host cells in two cell types. RNA isolated from PA14 OMV exposed primary human bronchial epithelial cells or CFBE41o- bronchial epithelial cells as well as unexposed control cells was analyzed by small RNA-Seq. Primary cell exposures were performed on two donors and exposures of CFBE41o- cells were done in triplicate.

Comparative Profiling of Pseudomonas aeruginosa Strains Reveals Differential Expression of Novel Unique and Conserved Small RNAs

Project description:Pseudomonas aeruginosa is a highly adaptable bacterium which thrives in a broad range of ecological niches and can infect multiple hosts as diverse as plants, nematodes and mammals. In humans, it is an important opportunistic pathogen. This wide adaptability correlates with its broad genetic diversity. In this study, we used a deep-sequencing approach to explore the complement of small RNAs (sRNAs) in P. aeruginosa as the number of such regulatory molecules previously identified in this organism is relatively low, considering its genome size, phenotypic diversity and adaptability. We have performed a comparative analysis of PAO1 and PA14 strains which share the same host range but differ in pathogenicity, PA14 being considerably more virulent in several model organisms. Altogether, we have identified more than 150 novel candidate sRNAs and validated a third of them by Northern blotting. Interestingly, a number of these novel sRNAs are strain-specific or showed strain-specific expression, strongly suggesting that they could be involved in determining specific phenotypic traits. 2 cDNA samples (enriched for different size ranges ) from each of two strains of Pseudomonas aeruginoasa (PAO1 and PA14) were sequenced with the Roche 454 technology

Expression profile of Pseudomonas aeruginosa ÎgcsR PAO1 using RNA-Seq

Project description:The TyrR-like enhancer-binding protein GcsR (or PA2449) was shown to regulate the expression of genes required for glycine metabolism. In order to define the regulon of GcsR we compared the transcriptome of a gcsR deletion mutant of P. aeruginosa PAO1 with that of the wild-type using RNA-Seq. Strains were grown under glycine rich conditions (peptone broth) and their transcriptomes were compared using RNA-Seq.

Proteomics of Pseudomonas aeruginosa PAO1 and PA14

Project description:Recent studies have shown that the concentrations of proteins expressed from orthologous genes are often conserved across organisms, and to a greater extent than the abundances of the corresponding mRNAs. However, such studies have not distinguished between evolutionary (e.g., sequence divergence) and environmental (e.g., growth condition) effects on the regulation of steady-state protein and mRNA abundances. Here we systematically investigated the transcriptome and proteome of two closely related Pseudomonas aeruginosa strains, PAO1 and PA14, under identical experimental conditions, thus controlling for environmental effects. For 703 genes observed by both shotgun proteomics and microarray experiments, we find that the protein-to-mRNA ratios are highly correlated between orthologous genes in the two strains, to an extent comparable to protein and mRNA abundances. In spite of this high molecular similarity between PAO1 and PA14, we found that several metabolic, virulence, and antibiotic resistance genes are differentially expressed between the two strains, mostly at the protein but not at the mRNA level. Our data demonstrate that post-transcriptional regulation is important for understanding the discordance between mRNA and protein abundance.

Molecular Mechanisms of Master Regulator VqsM mediating Quorum-sensing and Antibiotic Resistance in Pseudomonas aeruginosa

Project description:The Pseudomonas aeruginosa quorum-sensing (QS) systems contribute to bacterial homeostasis and pathogenicity. Although the AraC family transcription factor VqsM has been characterized to control the production of virulence factors and QS signaling molecules, its detailed regulatory mechanisms still remain elusive. Here, we report that VqsM directly binds to the lasI promoter region, and thus regulates its expression. To identify additional targets of VqsM in P. aeruginosa PAO1, we performed chromatin immunoprecipitation followed by high-throughput DNA sequencing (ChIP-seq) which detected 48 enriched loci harboring VqsM-binding peaks in P. aeruginosa genome. The direct regulation of these genes by VqsM has been confirmed by Electrophoretic mobility shift assays (EMSAs) and quantitative real-time polymerase chain reactions (qRT-PCR). A VqsM-binding motif is found by using MEME suite and verified by footprint assays in vitro. In addition, VqsM directly binds to the promoter regions of antibiotic resistance regulator NfxB and the master type III system regulator ExsA. Notably, the vqsM mutant displayed more resistance to two types of antibiotics and promoted bacterial survival in a mouse model, compared to the wild type PAO1 strain. Collectively, this work provides new cues to better understand the detailed regulatory networks of QS systems, T3SS, and antibiotic resistance.

Project description:The Pseudomonas aeruginosa quorum-sensing (QS) systems contribute to bacterial homeostasis and pathogenicity. Although many regulators have been characterized to control the production of virulence factors and QS signaling molecules, its detailed regulatory mechanisms still remain elusive. Here, we performed chromatin immunoprecipitation followed by high-throughput DNA sequencing (ChIP-seq) on 10 key QS regulators. The direct regulation of these genes by corresponding regulator has been confirmed by Electrophoretic mobility shift assays (EMSAs) and quantitative real-time polymerase chain reactions (qRT-PCR). Binding motifs are found by using MEME suite and verified by footprint assays in vitro. Collectively, this work provides new cues to better understand the detailed regulatory networks of QS systems.
