Strand inequality in terms of expression-dependent synonymous single-nucleotide polymorphism in the Escherichia coli chromosome

The paper analyzes synonymous SNPs in E. coli to show strand and expression-dependent mutation patterns, demonstrating transcription-induced mutagenesis contributes to strand inequality.

Polymorphism at four-fold degenerate site, but not at the intergenic regions, explains nucleotide compositional strand asymmetry in bacteria

The paper examines polymorphism in intergenic regions and four-fold degenerate sites in bacterial genomes to explain nucleotide compositional strand asymmetry, finding that FFS polymorphisms, not IRs, explain the asymmetry.
