Integrative DNA methylome and transcriptome analysis reveals DNA adenine methylation is involved in Salmonella enterica Typhimurium response to oxidative stress.

ABSTRACT:

Importance

The intracellular pathogen Salmonella enterica serovar Typhimurium (S. Typhimurium) comes across a wide variety of stresses from entry to dissemination, such as reactive oxygen species. To adapt itself to oxidative stress, Salmonella must adopt various and complex strategies. In this study, we revealed that DNA adenine methyltransferase was essential for S. Typhimurium to survive in hydrogen peroxide. We then screened out oxidative stress-responsive genes that were potentially regulated by DNA methylation in S. Typhimurium. Our results show that the DNA methylome is highly stable throughout the genome, and the coupled change of m6A GATC with gene expression is identified in only a few positions, which suggests the complexity of the DNA
