The paper identifies and analyzes endogenous dsDNA viral elements across eukaryotic genomes, revealing their distribution and associations with specific host lineages and viral taxa.

The paper analyzes viral aminoacyl-tRNA synthetases (aaRSs) in nucleocytoviruses to determine their evolutionary origins and find that some predate the last common eukaryotic ancestor.

The paper discovers a new group of DNA viruses, egoviruses, found in the digestive systems of humans and animals, closely related to poxviruses and suggesting an evolutionary link between gut-infecting viruses and animal pathogens.

The paper investigates viral horizontal gene transfer (vHGT) among nucleocytoviruses and finds it accounts for 28% to 42% of gene gain events in each viral order.
