Cell wall-deficient bacteria referred to as L-forms have lost the ability to maintain or build a rigid peptidoglycan envelope. We have generated stable, non-reverting L-form variants of the Gram-positive pathogen Listeria monocytogenes, and studied the cellular and molecular changes associated with this transition. Stable L-form cells can occur as small protoplast-like vesicles and as multinucleated, large bodies. They have lost the thick, multilayered murein sacculus and are surrounded by a cyt ...[more]

CSL ChIP-seq

Project description:The expression of a large proportion of the fission yeast genome changes periodically with the cell cycle. Several key transcription factors have been identified that regulate these oscillating and interdependent waves of gene expression. However, for a significant number of cell cycle-regulated genes the regulator(s) driving these oscillations remain unknown. Cbf11 and Cbf12, the fission yeast CSL transcription factors, have been implicated in the regulation of cell cycle progression, yet the details of their functioning are poorly understood. Using a combination of transcriptome profiling and genome-wide mapping of CSL-DNA interactions we have identified a comprehensive set of CSL-regulated genes. Our data indicate that Cbf11 and Cbf12 contribute directly and indirectly to the regulation of periodically expressed genes in fission yeast. We show that during S phase/cytokinesis Cbf11 directly activates the transcription of several periodic genes required in the cell to prevent catastrophic mitosis. In agreement with these findings, multiple aspects of cell cycle progression are perturbed when CSL cellular levels are genetically manipulated. We have identified Cbf11 as a novel cell cycle phase-specific activator of genes required for proper coordination of cell and nuclear division, and prevention of catastrophic mitosis in fission yeast.

Transcription profiling of Salmonella enterica serotype SL1344 wildtype, pSf-R27sfh and pSf-R27 at stationary and exponential growth phases, to investigate the role of the Sfh protein encoded by transmissible plasmids and involved in human typhoid

Project description:The Sfh protein is encoded by self-transmissible plasmids involved in human typhoid and is closely related to the global regulator H-NS. We have found that Sfh provides a stealth function that allows the plasmids to be transmitted to new bacterial hosts with minimal effects on their fitness. Introducing the plasmid without the sfh gene imposes a mild H-NS- phenotype and a severe loss of fitness due to titration of the cellular pool of H-NS by the A+T-rich plasmid. This stealth strategy seems to be used widely to aid horizontal DNA transmission and has important implications for bacterial evolution.

Transcription profiling of wild type and ZakA and GskA knock-out Dictyostelium discoideum to investigate the Zak1-GSK-3 signalling pathway

Project description:GskA, the Dictyostelium GSK-3 orthologue, is modified and activated by the dual-specificity tyrosine kinase Zak1 and the two kinases form part of a signalling pathway that responds to extracellular cAMP. We identify potential cellular effectors for the two kinases by analysing their null mutants. There are proteins and mRNAs that are altered in abundance in only one or other of the two mutants, indicating that each kinase has some unique functions. However, proteomic and micro-array analysis respectively identified 3 proteins and 37 genes that are similarly mis-regulated in both mutant strains. The positive correlation between the array data and the proteomics data is consistent with the Zak1-GskA signalling pathway functioning by directly or indirectly regulating gene expression. The discoidin 1 genes are positively regulated by the pathway while the abundance of the H5 protein is negatively regulated. Two of the targets, H5 and discoidin 1, are well-characterised markers for early development, indicating that the Zak1-GskA pathway plays a role in development earlier than previously observed.

Transcription profiling of wild type and mutant fission yeast exposed to different intensities of H202 and two other oxidants

Project description:We studied transcriptional responses of the fission yeast Schizosaccharomyces pombe to different intensities of H2O2 stress as well as two other oxidants: menadione sodium bisulfite and tert-butyl hydroperoxide. DNA microarrays were used to study the changes in expression profiles and the transcriptional regulation. We compare and contrast global expression and regulation of different intensities of H2O2 stress and different oxidants. The transcriptional response to low doses of H2O2 is very similar to menadione sodium bisulfite and the genes were controlled primarily by the transcription factor Pap1. The transcriptional response to medium and high doses of H2O2 is very similar to tert-butyl hydroperoxide and the genes were mostly regulated by the stress-activated MAP kinase Sty1p and the transcription factor Atf1p. We also compare global regulation of oxidative stress genes in fission and budding yeasts and discuss evolutionary implications.

Transcription profiling of fission yeast Pht1 (H2A.Z) deletion mutants

Project description:Histone variant H2A.Z has a conserved role in genome stability, although it remains unclear how this is mediated. Here we demonstrate that the fission yeast Swr1 1 ATPase inserts H2A.Z (Pht1) into chromatin and Kat5 acetyltransferase (Mst1) acetylates it. Deletion or an unacetylatable mutation of Pht1 1 leads to genome instability, primarily caused by chromosome entanglement and breakage at anaphase. This leads to the loss of telomere-proximal markers, though telomere protection and repeat length are unaffected by the absence of Pht1. Strikingly, the chromosome entanglement in pht1? anaphase cells can be rescued by forcing chromosome condensation before anaphase onset. We show that the condensin complex, required for the maintenance of anaphase chromosome condensation, prematurely dissociates from chromatin in the absence of Pht1. This and other findings suggest an important role for H2A.Z in the architecture of anaphase chromosomes.

Comparative genomic hybridization of strains of Salmonella enterica serovar Enteritidis from Uruguay, other distant geographical regions and other serovars isolated in Uruguay

Project description:Microarray based CGH was conducted over a group of 29 strains of S. Enteritidis spanning different epidemiological periods in Uruguay, plus 6 other S. Enteritidis strains isolated from distant geographical regions. We also included 9 Salmonella enterica strains of other serovars isolated in Uruguay. A S. Enteritidis dispensable genome of 233 chromosomal genes and high extent of variation in virulence plasmid was found. Strains isolated before the epidemic show the highest genomic differences as compared with the PT4 reference strain. Comparison with the gene content of other serovars demonstrate extensive horizontal gene transfer between circulating strains beyond serovar definition. Our results show that the epidemic of S Enteritidis in Uruguay was produced by the introduction of strains closely related to PT4, and corroborate the extensive genetic homogeneity among S. Enteritidis isolates worldwide. Phage SE14 emerges as the only specific region for S. Enteritidis. Genetic differences detected in pre-epidemic strains, mainly associated with the absence of phage SE20, suggest that genetic features encoded in this phage may be related to particular epidemiological behavior.

Transcription profiling of fission yeast timecourse pmh1 mutant

Project description:The fission yeast Mcs6-Mcs2-Pmh1 complex (homologous to metazoan Cdk7-cyclin HMat1) performs dual functions: in cell cycle control, as a CDK-activating kinase; and in transcription by RNA polymerase (Pol) II, as part of TFIIH. It is unknown whether that linkage serves to coordinate gene expression with cell division. Mutants in mcs6 and pmh1 arrest with incomplete cell separation and decreased phosphorylation of the Pol II large subunit. Gene expression profiling by microarray hybridization revealed that a defined subset (~5%) of genes was repressed by Mcs6 complex impairment, whereas the majority was refractory. The repression signature included a cell-cycle cluster implicated in cytokinesis and cell separation, and overlapped with those of the cell-separation mutants sep1, sep10 and sep15 (relative to wild-type cells). The gene sep10 encodes the homolog of a protein found in metazoan Mediator-like complexes, and sep15 encodes an established component of the Mediator. In mcs6 or pmh1 mutants, sep10+, which also encodes a component of the transcriptional machinery, becomes essential for viability. Finally, mcs6+ also interacts genetically with sep1+, which encodes a forkhead transcription factor required for periodic transcription during mitosis and cell division. Thus, the Mcs6 complex (a direct activator of the cell-cycle engine) also helps govern the cell-cycle transcriptional program.
