RpoS regulation of gene expression during exponential growth of Escherichia coli K12Tao Dong
Department of Biology, McMaster University, Life Sciences Building, Rm 433, 1280 Main Street West, Hamilton, ON, Canada, L8S 4K1
Mol Genet Genomics 279:267-77. 2008..In summary, the identification of a group of exponential phase genes controlled by RpoS reveals a novel aspect of RpoS function...
Control of RpoS in global gene expression of Escherichia coli in minimal mediaTao Dong
Department of Biology, McMaster University, Life Sciences Building, Rm 433, 1280 Main Street West, Hamilton, ON, L8S 4K1, Canada
Mol Genet Genomics 281:19-33. 2009..Consistent with this, the motility of rpoS mutants was enhanced relative to WT. In conclusion, RpoS and its controlled regulators form a complex regulatory network that mediates the expression of a large regulon in minimal media...
Polymorphism and selection of rpoS in pathogenic Escherichia coliTao Dong
Department of Biology, Life Sciences Building, RM, 433, McMaster University, 1280 Main Street West, Hamilton, ON, L8S 4K1, Canada
BMC Microbiol 9:118. 2009..However, the causes of this polymorphism and consequential physiological effects on gene expression in pathogenic strains are not fully understood...- Global effect of RpoS on gene expression in pathogenic Escherichia coli O157:H7 strain EDL933Tao Dong
Department of Biology Life Sciences Building, RM, 433, McMaster University, 1280 Main Street, West Hamilton, ON L8S 4K1, Canada
BMC Genomics 10:349. 2009..The genomic difference may result in substantial changes in RpoS-regulated gene expression. To test this, we compared the transcriptional profile of wild type and rpoS mutants of the E. coli O157:H7 EDL933 type strain... - Phenotypic diversity caused by differential RpoS activity among environmental Escherichia coli isolatesSarah M Chiang
Life Sciences Building, Rm 433, McMaster University, 1280 Main St West, Hamilton, Ontario, Canada
Appl Environ Microbiol 77:7915-23. 2011..coli. RpoS selection may be an important determinant of phenotypic diversification and, hence, the survival of E. coli in the environment... - Antagonistic regulation of motility and transcriptome expression by RpoN and RpoS in Escherichia coliTao Dong
Department of Biology, McMaster University, Hamilton, ON, L8S4K1 Canada
Mol Microbiol 79:375-86. 2011..These findings unveil a complex regulatory interaction among σ(N) , σ(S) and σ(F) , which modulates motility, nitrogen utilization, stress response and many other cellular functions... - Stationary phase expression of the arginine biosynthetic operon argCBH in Escherichia coliJeevaka P Weerasinghe
McMaster University, Department of Biology, Life Sciences Building, RM, 218, 1280 Main Street West, Hamilton, ON, Canada, L8S 4K1
BMC Microbiol 6:14. 2006..Though control of the pathway in response to arginine limitation is largely modulated by the ArgR repressor, other factors may be involved in increased stationary phase and stress expression... - Role of RpoS in the virulence of Citrobacter rodentiumTao Dong
Department of Biology, Life Sciences Building, Rm 433, McMaster University, 1280 Main Street West, Hamilton, Ontario L8S 4K1, Canada
Infect Immun 77:501-7. 2009..In conclusion, RpoS is important for the stress response and is required for full virulence in C. rodentium... - Role of RpoS in virulence of pathogensTao Dong
McMaster University, Department of Biology, Life Sciences Building, Rm 433, 1280 Main Street West, Hamilton, Ontario L8S 4K1, Canada
Infect Immun 78:887-97. 2010..In this review, we focus on the distinct and niche-dependent role of RpoS in virulence by surveying recent findings in many pathogens...
