Abstract: Abstract Operons are a hallmark of the genomic and regulatory architecture of prokaryotes. However, the mechanism by which two genes placed far apart gradually come close and form operons remains to be elucidated. Here, we… read more here.

DOI: 10.1093/nar/gkad017
Abstract: Abstract Bacterial genomes contain an abundance of transposable insertion sequence (IS) elements that are essential for genome evolution and fitness. Among them, IS629 is present in most strains of enterohemorrhagic Escherichia coli O157 and accounts… read more here.

DOI: 10.1128/aem.01279-17
Abstract: ABSTRACT Lactococcus lactis subsp. cremoris strains typically carry many dairy niche-specific adaptations. During adaptation to the milk environment these former plant strains have acquired various pseudogenes and insertion sequence elements indicative of ongoing genome decay… read more here.

Abstract: In this study we examined whether the same nim gene-insertion sequence (IS) element combinations give rise to the same expression levels as they harbor shared IS element-borne promoters. From our quantitative analysis, we found that… read more here.

DOI: 10.3389/fmicb.2023.1110084
Abstract: Deinococcus radiopugnans DY59 (formerly Deinococcus swuensis DY59) is a radiation-resistant bacterium isolated from soil. From the 3.5 Mb genomic DNA sequence of strain DY59 (December 2014), 31 insertion sequence (IS) elements of six IS families including… read more here.
