Isolation of a gokushovirus capable of lysogenizing enterobacteria challenges previous notions about the biology of the most prolific phages within the Microviridae and facilitates experimental study in a model organism.

A bioinformatics pipeline has annotated over 2,500 complete genomes of circular DNA viruses belonging to dozens of established and emerging viral families.

Single-cell amplified genome sequencing uncovers virus-host interactions in uncultivated sulfur-oxidizing bacteria with relevance to coupled biogeochemical cycling in marine oxygen minimum zones.

From public microbial genomes, VirSorter revealed 12,498 viral genome sequences that expand the map of the global virosphere and whose analyses improve understanding of viral taxonomy, evolution and virus-host interactions.

The characterization of ancient B19V and HBV genotype A4 viruses circulating during Colonial epidemics provides new insights into the pathogens that were introduced to the Americas after the European colonization.

In triple-layered rotavirus particles, strong interaction between the external and middle layers provides high mechanical strength for protection tasks, while weaker interaction between the middle and inner layers favors transcription.

Chronic bacteriophages are induced by the supplement of polysaccharide in the deep-sea Lentisphaerae strains, and these bacteriophages potentially reprogram host polysaccharide metabolism through the auxiliary metabolic genes.

A phage parasite encodes an external scaffolding protein to pirate and rearrange phage-encoded coat proteins to more efficiently transfer the phage parasite genome to new hosts and limit phage production.

Domestication of endosymbiotic Mollicutes may have resolved nitrogen-recycling challenges for attine ants and enabled the evolutionary derived leaf-cutting ants to fully exploit their herbivorous niches.
