Virus communities are associated with the degradation of recalcitrant carbon during the corpse decay of plateau pika (Ochoton curzoniae)

Grassland Research, Volume 4, Issue 3, Page 281-293, September 2025.
Abstract Background It has been reported that bacteria and fungi play a vital role in soil biogeochemical cycles during the decomposition of animal corpses. However, it is poorly understood how the viral composition and function of grassland soil change during the decay of wild mammal corpses.

Large, double‐stranded DNA viruses tend to suppress phytoplankton populations more effectively than small viruses of diverse genome type

Limnology and Oceanography Letters, Volume 10, Issue 5, Page 745-753, September 2025.
Abstract Viruses infecting aquatic microbes vary immensely in size, but the ecological consequences of virus size are poorly understood. Here we used a unique suite of diverse phytoplankton strains and their viruses, all isolated from waters around Hawai'i, to assess whether virus size affects the suppression of host populations.

The Hologenome of Haliclona fulva (Porifera, Demospongiae) Reveals an Abundant and Diverse Viral Community

Frontiers in Marine Science, 2021
Viruses are among the most abundant biological entities in the ocean, largely responsible of modulating nutrients fluxes and influencing microbial composition and functioning.

Formalin‐fixed paraffin‐embedded (FFPE) samples help to investigate transcriptomic responses in wildlife disease

Molecular Ecology Resources, Volume 25, Issue 5, July 2025.
Abstract Infectious diseases impact numerous organisms. Knowledge of host‐pathogen interactions and host responses to infection is crucial for conservation and management. Obtaining this knowledge quickly is made increasingly possible by a variety of genomic approaches, yet, for many species the bottleneck to understanding this, remains access to ...

Gut Virome of Tibetan Pigs Reveals the Diversity, Composition, and Distribution of Potential Novel Viruses/Variants

Transboundary and Emerging Diseases, Volume 2025, Issue 1, 2025.
As a local breed adapted to the extreme environment of the Tibetan Plateau, Tibetan pigs have not yet been systematically characterized in terms of their gut viral communities. In this study, we applied viral metagenomics to sequence fecal samples from 191 Tibetan pigs (including both healthy and diarrheal individuals) across four farms in Nyingchi ...

The kinetoplastid-infecting Bodo saltans virus (BsV), a window into the most abundant giant viruses in the sea

eLife, 2018
Giant viruses are ecologically important players in aquatic ecosystems that have challenged concepts of what constitutes a virus. Herein, we present the giant Bodo saltans virus (BsV), the first characterized representative of the most abundant group of ...

The effects of stress on gut virome: Implications on infectious disease and systemic disorders

MicrobiologyOpen, Volume 13, Issue 5, October 2024.
Stress conditions can weaken the host's immune system, affecting the entire gut–brain axis. Concurrently, disruptions in the composition of the gut microbiota are associated with exacerbations of diseases. This review explores the complex interplay between stress, gut virome, and the host immune system.

A panoramic view of the virosphere in three wastewater treatment plants by integrating viral‐like particle‐concentrated and traditional non‐concentrated metagenomic approaches

iMeta, Volume 3, Issue 3, June 2024.
Our comparative analysis unveiled the distinct advantages of two methods in capturing the complexity of viral communities and their functions in wastewater treatment plants. The non‐concentrated (NC) metagenomic approach identified a higher number of viral contigs, though it had a lower yield of high‐quality contigs.

Role of the R349 Gene and Its Repeats in the MIMIVIRE Defense System

Frontiers in Microbiology, 2019
MIMIVIRE is a defense system described in lineage A Mimivirus (Mimiviridae family) that mediates resistance against Zamilon virophage. It is composed of putative helicase and nuclease associated with a gene of unknown function called R349, which contains

Dinucleotide biases in the genomes of prokaryotic and eukaryotic dsDNA viruses and their hosts

Molecular Ecology, Volume 33, Issue 6, March 2024.
Abstract The genomes of cellular organisms display CpG and TpA dinucleotide composition biases. Such biases have been poorly investigated in dsDNA viruses. Here, we show that in dsDNA virus, bacterial, and eukaryotic genomes, the representation of TpA and CpG dinucleotides is strongly dependent on genomic G + C content.
