This study introduces a new framework for analyzing bacterial epigenomes at population scale. It reveals how epigenetic modifications influence bacterial evolution, stress resilience, and pathogenicity, particularly in horizontally acquired genes.

Area of Science:

Microbiology
Genomics
Epigenetics

Background:

Eukaryotic methylome maps have advanced understanding of development and disease.
Bacterial epigenomes remain largely unexplored despite bacteria's abundance and ecological diversity.

Purpose of the Study:

To develop a strategy for population-scale comparison of bacterial methylomes.
To enable quantitative comparative analysis of bacterial epigenomes.

Main Methods:

Prioritization of enzymatically encoded, conserved, and phylogenetically informative methylation systems.
Reconstruction of population-scale bacterial methylation-informed phylogenies.
Development of a three-metric quantitative framework (MPK, MR, MFR) for methylation data analysis.

Keywords:

biology, computational biology dna methylation epigenetics epigenome epigenomics genetic code genetics quantitative trait locus

Main Results:

First population-scale bacterial methylation-informed phylogenies were reconstructed, recapitulating sequence-based relationships and identifying epi-phylogroups linked to GC content and stress resilience.
A quantitative framework enabled identification of highly methylated core genes in Escherichia coli.
Co-methylation network analysis revealed virulence-enriched modules and epigenetic assimilation of horizontally acquired virulence loci.

Conclusions:

The developed framework allows for locus-resolved, population-scale integration of bacterial methylation data.
Epigenetic modifications contribute to bacterial evolution, fitness, and pathogenicity.
Horizontally acquired virulence loci are epigenetically assimilated into host regulatory circuitry.
