Bacteria live under constant assault by bacteriophages and have evolved a diverse array of
defense strategies. CRISPR-Cas systems are prokaryotic adaptive immune systems that rely …

Molecular genetics has taught us new ways to think about bacterial genomes and how they
change during evolution. We have elucidated the structure of genetic determinants that …

A transposable element, or transposon, is a discrete segment of DNA that can move
between non-homologous DNA sites in a host cell. The movement of a transposable …

Mobile genetic elements (MGEs) have played a fundamental role in the evolution of complex
organisms, driving innovation through competition, collaboration and co-option …

Bacterial species and communities play foundational roles in human health and
therapeutics, in vital ecological and environmental processes, and in industrial applications …

RESULTS Effect of MOI and RecD on transposition frequency. Figure 1 represents the

Transposable elements (TEs) are genomic parasites that proliferate within host genomes,
and can also invade new species. The P-element, a DNA-based transposable element …

This chapter talks about four different families of transposable DNA elements and describes
how transposon‐mediated recombination molds the organization of the bacterial …

Transposition is a DNA rearrangement in which a mobile DNA element inserts into target
sites in a host genome. Although insertions may occur into many different sites, transposons …
