Horizontal gene transfer among host-associated microbes
Horizontal gene transfer is an important evolutionary force, facilitating bacterial diversity. It is
thought to be pervasive in host-associated microbiomes, where bacterial densities are high …

Open questions in the social lives of viruses
Social interactions among viruses occur whenever multiple viral genomes infect the same
cells, hosts, or populations of hosts. Viral social interactions range from cooperation to …

The defense island repertoire of the Escherichia coli pan-genome
It has become clear in recent years that anti-phage defense systems cluster non-randomly
within bacterial genomes in so-called “defense islands”. Despite serving as a valuable tool …

A Vibrio cholerae viral satellite maximizes its spread and inhibits phage by remodeling hijacked phage coat proteins into small capsids
Phage satellites commonly remodel capsids they hijack from the phages they parasitize, but
only a few mechanisms regulating the change in capsid size have been reported. Here, we …
