Commensal Viruses Promote Intestinal Stem Cell Regeneration Following Radiation Damage by Inhibiting Hyperactivation of RIG‐I and Notch Signals

Advanced Science, Volume 12, Issue 37, October 6, 2025.
Ionizing radiation disrupts gut virome and bacteriome. Gut commensal viruses protect against intestinal damage and promote stem cell regeneration by inhibiting hyperactivation of RIG‐I and Notch signaling in stem cells. Fecal virome transplantation (FVT) from healthy donors can serve as a potential therapeutic intervention by enriching phages targeting

Draft genome sequences of Terra1 and Terra2 viruses, new members of the family Mimiviridae isolated from soil

Virology, 2014
Since the discovery of Mimivirus, the founding member of the family Mimiviridae, three lineages, A-C, have been delineated among the mimiviruses of amoebae. To date, all giant viruses with annotated genomes have been isolated from water samples. Here, we describe the genome of two mimiviruses, Terra1 virus and Terra2 virus, which were recovered by co ...

A Next-Generation Sequencing Approach Uncovers Viral Transcripts Incorporated in Poxvirus Virions

Viruses, 2017
Transcripts are known to be incorporated in particles of DNA viruses belonging to the families of Herpesviridae and Mimiviridae, but the presence of transcripts in other DNA viruses, such as poxviruses, has not been analyzed yet.

Lausannevirus Encodes a Functional Dihydrofolate Reductase Susceptible to Proguanil. [PDF]

, 2017
Lausannevirus belongs to the family Marseilleviridae within the group of nucleocytoplasmic large DNA viruses (NCLDVs). These giant viruses exhibit unique features, including a large genome, ranging from 100 kb to 2.5 Mb and including from 150 to more ...

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.

Biogeography of marine giant viruses reveals their interplay with eukaryotes and ecological functions [PDF]

, 2020
海洋巨大ウイルスの地理的分布を全球規模で解明 --海域による特異性が明らかに--. 京都大学プレスリリース. 2020-09-08.Nucleocytoplasmic large DNA viruses (NCLDVs) are ubiquitous in marine environments and infect diverse eukaryotes. However, little is known about their biogeography and ecology in the ocean.

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 ...
