Metagenome-derived virus-microbe ratios across ecosystems

Purificacion Lopez-Garcia et al.

Summary: A metagenome-based method was used to estimate the virus-to-microbe ratio, and it was found that viruses may be much less abundant than previously thought, especially in non-aquatic environments.

Mirusviruses link herpesviruses to giant viruses

Morgan Gaia et al.

Summary: DNA viruses have a significant impact on the ecology and evolution of cellular organisms, but their overall diversity and evolutionary paths are still unclear. This study discovered plankton-infecting relatives of herpesviruses in the sunlit oceans, which belong to a new phylum named Mirusviricota. These mirusviruses exhibit chimaeric attributes connecting them to both herpesviruses and giant eukaryotic viruses, and they play a lasting role in the ecology of marine ecosystems and the evolution of eukaryotic DNA viruses.

Giant Viruses Encode Actin-Related Proteins

Violette Da Cunha et al.

Summary: This study reveals the presence and expression of actin-related genes in viral genomes, suggesting that viruses recruited these genes from ancient protoeukaryotic hosts and transferred them to give rise to eukaryotic actins, which could have contributed to the emergence of the modern eukaryotic cytoskeleton.

Systematic evaluation of horizontal gene transfer between eukaryotes and viruses

Nicholas A. T. Irwin et al.

Summary: This study systematically characterized viral-eukaryotic gene exchange, identifying thousands of transfers and revealing their frequency, taxonomic distribution, and predicted functions. The findings highlight the impact of virus-host interactions on evolutionary changes, as well as common strategies employed by viruses to manipulate hosts, such as metabolic reprogramming, proteolytic degradation, and extracellular modification. Additionally, the study implicates genetic exchange in the early evolution and diversification of eukaryotes, particularly through viral-derived glycosyltransferases impacting a wide range of structures.

Recent changes to virus taxonomy ratified by the International Committee on Taxonomy of Viruses (2022)

Peter J. Walker et al.

Summary: This article discusses the changes in virus taxonomy approved by the International Committee on Taxonomy of Viruses (ICTV) in March 2022. The ICTV members voted on 174 taxonomic proposals, all of which were ratified by an absolute majority. The implementation of a new naming rule for virus species has resulted in over 60% of virus species being named in the 'Genus_name species_epithet' format.

Viral origin of eukaryotic type IIA DNA topoisomerases

Julien Guglielmini et al.

Summary: Type II DNA topoisomerases of the family A (Topo IIAs) are present in all Bacteria and eukaryotes. The origin of eukaryotic Topo IIA remains mysterious, but they have close homologs in large viruses and may have been acquired from them. This highlights the important role of viruses in eukaryogenesis and suggests early proto-eukaryotes used a different type of topoisomerase to solve DNA topological problems.

Protist impacts on marine cyanovirocell metabolism

Cristina Howard-Varona et al.

Summary: This study investigated the population-level responses of cyanobacterial viral cells to the presence of protists. The presence of protists did not have a measurable impact on the transcription and endometabolite levels of the viral cells, but it did lead to changes in the intracellular transcription and metabolic responses, as well as increased photosynthetic efficiency.

Phylogeny of the Varidnaviria Morphogenesis Module: Congruence and Incongruence With the Tree of Life and Viral Taxonomy

Anthony C. C. Woo et al.

Summary: Double-stranded DNA viruses of the realm Varidnaviria share homologous major capsid proteins (MCPs) and packaging ATPases (pATPases) and infect hosts from the three domains of life, suggesting a common ancestor. The evolutionary history of Varidnaviria shows complex characteristics, with Sphaerolipoviridae exhibiting divergent MCPs and pATPases grouping with Bamfordvirae. The grouping of Bamfordvirae infecting archaea with those infecting bacteria, in contradiction with the cellular tree of life, presents questions on the validity of Adenoviridae and Helvetiavirae ranking.

The Virophage Family Lavidaviridae

Matthias G. Fischer

Summary: Virophages of the family Lavidaviridae are eukaryotic viruses that rely on coinfecting giant viruses for their propagation, inhibiting the replication of these giant viruses. Their genomes are relatively small and can be found in various aquatic environments globally, with genetic elements shared with other viruses. Further research is needed to answer key questions about their infection cycle, host range, and ecology.
