The dual lifestyle of genome‐integrating virophages in protists

Annals of the New York Academy of Sciences, 2019
AbstractDNA viruses with efficient host genome integration capability were unknown in eukaryotes until recently. The discovery of virophages, satellite‐like DNA viruses that depend on lytic giant viruses that infect protists, revealed a genetically diverse group of viruses with high genome mobility.

Microalga–virus–virophage coculture reveals co-infection of multi-virophages with a giant virus

Archives of Virology
Virophages parasitize the replication of co-infecting giant viruses within eukaryotic cells, forming tripartite cell-virus-virophage (CVv) systems. Tripartite interactions are well-documented in protozoa, yet comparable systems in algae remain largely unexplored at the experimental level. Here, we report an experimentally validated CVv system involving

Les virophages de Mimiviridae=The Mimiviridae virophages

Les virophages sont des petits virus à ADN possédant une capside icosaédrique de 50-60 nm et un génome de 17 à 26 Kb codant potentiellement pour une vingtaine de gènes. Ils ont été découverts associés à des grands virus à ADN appartenant à l’ordre des Megavirales, pour lesquels leur présence serait délétère.Le premier projet du travail de thèse a été ...

Mimiviridae et virophages

Mimivirus est le 1er virus géant découvert. Quelques années plus tard une nouvelle entité́ biologique a été décrite, les virophages. Si leurs principales caractéristiques sont maintenant bien définies et acceptées, leur position dans le monde viral ainsi que les interactions qu’ils pourraient avoir avec leur virus-hôte sont encore discutées.

Virophages to viromes: a report from the frontier of viral oceanography

Current Opinion in Virology, 2011
The investigation of marine viruses has advanced our understanding of ecology, evolution, microbiology, oceanography and virology. Significant findings discussed in this review include the discovery of giant viruses that have genome sizes and metabolic capabilities that distort the line between virus and cell, viruses that participate in photosynthesis

Virophage replication mode determines ecological and evolutionary changes in a host-virus-virophage system

Abstract Giant viruses can control their eukaryotic host populations, shaping the ecology and evolution of aquatic microbial communities. Understanding the impact of the viruses’ own parasites, the virophages, on their control of microbial communities remains a challenge.

[Prediction of Promoter Motifs in Virophages].

Bing du xue bao = Chinese journal of virology, 2015
Virophages have crucial roles in ecosystems and are the transport vectors of genetic materials. To shed light on regulation and control mechanisms in virophage--host systems as well as evolution between virophages and their hosts, the promoter motifs of virophages were predicted on the upstream regions of start codons using an analytical tool for ...
