Transposable elements (TEs) are ubiquitous in both prokaryotes and eukaryotes, and the
dynamic character of their interaction with host genomes brings about numerous …

Paleovirology is the study of ancient viruses and how they have coevolved with their hosts.
An increasingly detailed understanding of the diversity, origins, and evolution of the DNA …

Accessory genes are variably present among members of a species and are a reservoir of
adaptive functions. In bacteria, differences in gene distributions among individuals largely …

Endosymbiosis with chemosynthetic bacteria has enabled many deep-sea invertebrates to
thrive at hydrothermal vents and cold seeps, but most previous studies on this mutualism …

Horizontal gene transfer (HGT) disseminates genetic information between species and is a
powerful mechanism of adaptation. Yet, we know little about its underlying drivers in …

The genomes of eukaryotes are full of parasitic sequences known as transposable elements
(TEs). Here, we report the discovery of a putative giant tyrosine-recombinase-mobilized DNA …

Flavivirids (family Flaviviridae) are a group of positive-strand ribonucleic acid (RNA) viruses
that pose serious risks to human and animal health on a global scale. Here, we use flavivirid …

Background Genomic regions that remain poorly understood, often referred to as the dark
genome, contain a variety of functionally relevant and biologically informative features …

Mavericks are virus-like mobile genetic elements found in the genomes of eukaryotes.
Although Mavericks encode capsid morphogenesis homologs, their viral particles have not …

Non-retroviral endogenous viral elements (nrEVEs) are widely dispersed throughout the
genomes of eukaryotes. Although nrEVEs are known to be involved in host antiviral …
