Expression analysis of Salmonella enterica serovar Typhimurium strain SL1344 with and without plasmid R27

ABSTRACT: Investigation of gene expression level changes in Salmonella Typhiumurium SL1344 (R27) compared to the wild-type SL1344 strain when grown at different growth temperatures and growth phases. A 24 microarray study was performed using total RNA recovered from three separate wild-type cultures of SL1344 and three separate cultures of SL1344 (R27) grown to exponential and stationary phase at 25oC and 37oC. Each microarray measured the expression level of 4,527 genes from Salmonella Typhimurium SL1344 chromosome, 103 genes from plasmid pSLT, 100 genes from plasmid pRSF, 14 genes from plasmid pCOL1B and 207 genes from plasmid R27. Seven probes were present per transcript, with two-fold technical redundancy.

Identification of Sfh and H-NS binding sites in the Salmonella Typhimurium genome

Project description:The global regulator H-NS represses transcription in gram negative bacteria. Sfh is a homologue of H-NS and is encoded by plasmid pSfR27. Sfh provides a 'stealth' function that allows pSfR27 to be transmitted to a new host without disrupting the competitive fitness of the new host We used ChIP-on-chip to profile Sfh (3xFLAG-tagged) and H-NS binding sites in Salmonella Typhimurium strain SL1344 and found that Sfh provides its 'stealth' function by targeting a sub-set of H-NS bound genes that display reduced levels of H-NS occupancy with the SL1344 chromosome upon acquisition of plasmid pSfR27 Identification of Sfh binding sites in strains SL1344 (pSfR27) and SL1344 hns (pSfR27) as well as identification of H-NS binding sites in strains SL1344, SL1344 (pSfR27), and SL1344 (pSfR27) sfh

Cappable-seq analysis of the Salmonella Typhimurium SL1344 transcriptome with overexpression of MarA, SoxS, Rob or RamA

Project description:Cappable-seq was used to map transcription start sites globally in Salmonella Typhimurium SL1344. In addition to naturally occurring plasmids pSLT and pCol1B9, the cells carry derivatives of plasmid pAMNF, or pAMNM, that drive low level constitutive expression of epitope tagged MarA, SoxS, Rob or RamA derivatives.

Cappable-seq analysis of the Salmonella Typhimurium SL1344 transcriptome

Project description:Cappable-seq was used to map transcription start sites globally in Salmonella Typhimurium SL1344. In addition to naturally occurring plasmids pSLT and pCol1B9, the cells carry plasmid pAMNF. The latter can be used for low level constitutive expression of a transcription factor of interest, though in these experiments no such ectopic transcription factor expression was used.
