Roles of DNA Adenine Methylation in Regulating Bacterial Gene Expression and Virulence [PDF]

Infection and Immunity, 2001
DNA methylation provides a mechanism by which additional information is imparted to DNA, and such epigenetic information can alter the timing and targeting of cellular events ([47][1]). DNA methylation occurs throughout the living world, including bacteria, plants, and mammals. Until recently,

Control of Bacterial Sulfite Detoxification by Conserved and Species-Specific Regulatory Circuits

Frontiers in Microbiology, 2019
Although sulfite, a by-product of the degradation of many sulfur compounds, is highly reactive and can cause damage to DNA, proteins and lipids, comparatively little is known about the regulation of sulfite-oxidizing enzyme (SOEs) expression.

Integration of the Salmonella Typhimurium Methylome and Transcriptome Reveals That DNA Methylation and Transcriptional Regulation Are Largely Decoupled under Virulence-Related Conditions

mBio, 2022
Despite being in a golden age of bacterial epigenomics, little work has systematically examined the plasticity and functional impacts of the bacterial DNA methylome.

The gut environment regulates bacterial gene expression which modulates susceptibility to bacteriophage infection

Cell Host & Microbe, 2022
Abundance and diversity of bacteria and their viral predators, bacteriophages (phages), in the digestive tract are associated with human health. Particularly intriguing is the long-term coexistence of these two antagonistic populations. We performed genome-wide RNA sequencing on a human enteroaggregative Escherichia coli isolate to identify genes ...

Mechanism of Gene Regulation by a Staphylococcus aureus Toxin

mBio, 2016
The virulence of many bacterial pathogens, including the important human pathogen Staphylococcus aureus, depends on the secretion of frequently large amounts of toxins. Toxin production involves the need for the bacteria to make physiological adjustments

The Major RNA-Binding Protein ProQ Impacts Virulence Gene Expression in Salmonella enterica Serovar Typhimurium

mBio, 2019
The protein ProQ has recently been discovered as the centerpiece of a previously overlooked “third domain” of small RNA-mediated control of gene expression in bacteria.

Use of Bacterial Quorum-Sensing Components to Regulate Gene Expression in Plants   [PDF]

Plant Physiology, 2006
Abstract We describe an efficient inducible system to regulate gene expression in plants based on quorum-sensing components found in Gram-negative bacteria such as Agrobacterium tumefaciens. These bacteria monitor their own population density by utilizing members of the N-acyl homoserine lactone family as inducers and a transcriptional ...

Expression profiles of XIK1 and OsSWEET14 genes in parental and back‐ crossing rice lines after Xanthomonas oryzae pv. oryzae infection

Indonesian Journal of Biotechnology
Oryza sativa L. ssp. indica (RD47 cultivar) is a major commercial rice variety known for its highly stable yields. However, it is highly susceptible to bacterial blight disease caused by Xanthomonas oryzae pv. oryzae (Xoo).
