A newly discovered genomic island enriched for glycosyltransferase genes in ErEurope. a Genome-wide counts of the GT2, GT4, and GT32 families by subspecies. b Annotated open reading frames of the GT-enriched part of a representative example of the genomic island specific to ErEurope. c Comparative genomic analysis of the genomic island (“Materials and methods”). The top five ErEurope strains contain the genomic island, whereas the bottom five do not. Colored segments connecting pairs of genes indicate orthologous genes inferred using progressiveMauve [33]. d GC content along the four contigs from ErEurope strains containing the ErEurope genomic island (“Materials and methods”). YSZC12003_37103 is not shown here because another genomic insertion would misalign the sequences. e Pairwise genetic distances between strains using orthologous genes from the genomic island are lower than those based on core genes. All 56 ErEurope strains with fully extracted genomic island are considered here
