Benchmarking of phylogenetic marker genes for Nucleocytoviricota.

, 2021
(A) Dotplot of protein lengths for each of the 9 marker genes examined in detail. Blue dots represent proteins that were the best hit against marker gene HMMs and likely represent true orthologs, while red dots represent multiple copies of marker genes ...

Echoes in the Deep: Revealing Influenza A Viruses’ Persistence and Microbial Associations in Aquatic Ecosystems

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
Background Influenza A viruses (IAVs) are significant pathogens with complex transmission dynamics in aquatic ecosystems, yet their persistence, evolutionary relationships, and associations with environmental microorganisms remain poorly understood. This study aimed to elucidate the phylogenetic characteristics and ecological associations of IAV in ...

Viral diversity and co‐evolutionary dynamics across the ant phylogeny

Molecular Ecology, Volume 33, Issue 19, October 2024.
Abstract Knowledge of viral biodiversity within insects, particularly within ants, is extremely limited with only a few environmental viruses from invasive ant species identified to date. This study documents and explores the viral communities in ants.

Viral communities in millipede guts: Insights into the diversity and potential role in modulating the microbiome

Environmental Microbiology, Volume 26, Issue 2, February 2024.
Relative abundance of the metagenome‐assembled viral genomes (bottom arch) identified in the hindgut metagenomes and metatranscriptomes of Epibolus pulchripes and Glomeris connexa. The top arch shows the coverage of each viral phylum mapped to the identified metagenome‐assembled viral genomes in transcripts per million.

Genomic adaptation of giant viruses in polar oceans

Nature Communications, 2023
Despite being perennially frigid, polar oceans form an ecosystem hosting high and unique biodiversity. Various organisms show different adaptive strategies in this habitat, but how viruses adapt to this environment is largely unknown.

Genome-resolved year-round dynamics reveal a broad range of giant virus microdiversity

mSystems
Giant viruses are crucial for marine ecosystem dynamics because they regulate microeukaryotic community structure, accelerate carbon and nutrient cycles, and drive the evolution of their hosts through co-evolutionary processes.

Fundamental Difficulties Prevent the Reconstruction of the Deep Phylogeny of Viruses

Viruses, 2020
The extension of virology beyond its traditional medical, veterinary, or agricultural applications, now called environmental virology, has shown that viruses are both the most numerous and diverse biological entities on Earth.

A Functional K⁺ Channel from Tetraselmis Virus 1, a Member of the Mimiviridae

Viruses, 2020
Potassium ion (K+) channels have been observed in diverse viruses that infect eukaryotic marine and freshwater algae. However, experimental evidence for functional K+ channels among these alga-infecting viruses has thus far been restricted to members of ...

Nucleocytoviricota Viral Factories Are Transient Organelles Made by Phase Separation

Phase separation is a common mechanism utilized by viruses to achieve replication, host manipulation and virion morphogenesis. The newly defined phylum _Nucleocytoviricota_ encompass ubiquitous and diverse viruses including _Poxviridae,_ the climate-modulating _Emiliania huxleyi_ virus and the previously termed Nucleocytoplasmic large DNA viruses ...

Climate Change, Giant Viruses and Their Putative Hosts

, 2023
Viruses hold our attention for the horrific impact they have on human health and welfare. However, viruses are a critical part of our ecosystem and facilitate the cycling of carbon and other important nutrients.
