Revisiting giant virus-host dynamics in brown algae: old stories and new perspectives [PDF]

The EMBO Journal
The recent discovery of widespread giant virus sequences integrated into the genomes of diverse eukaryotes, and in particular marine lineages, has reignited interest in the molecular mechanisms underlying giant virus–host interactions.

Ecosystem retrogression enhances cross‐domain microbial stability and increases the genetic potential for nutrient cycling [PDF]

mLife, Volume 5, Issue 4, Page 486-506, August 2026.
Abstract Ecosystem retrogression drives nutrient depletion, reduced productivity, and profound reorganization of soil microbial communities. Using amplicon sequencing and genome‐resolved metagenomics, we examined how cross‐domain microbial networks and functional gene potential respond to long‐term phosphorus and nitrogen limitation along the well ...

Refining a giant virus lineage: a novel order unifying Mamonoviridae and “Manesviridae,” unveiled by the discovery of furtivovirus [PDF]

Journal of Virology
The evolutionary origins and taxonomic framework of giant viruses related to the family Mamonoviridae and its relative group, including clandestinovirus, remain unclassified due to gaps in genome size and host range between these two groups.

Usurpativirus massiliensis, a new giant virus related to clandestinovirus [PDF]

Virology Journal
Giant virus discovery in 2003 revolutionized the virus paradigm. In 2015, we introduced a new host, Vermamoeba vermiformis, that led to the discovery of Faustovirus, Orpheovirus and two giant viruses (Clandestinovirus and a faustovirus) having distinct ...

Mirusviruses: a complex evolutionary trajectory beyond realms

, 2023
International audienceThe Varidnaviria and the Duplodnaviria are two very large cosmopolitan viral realms, comprising eukaryotic, bacterial, and archaeal viruses. Each is characterized by a distinct virion morphogenesis module and is hypothesized to have

Viral dynamics in a high-rate algal pond reveals a burst of Phycodnaviridae diversity correlated with episodic algal mortality [PDF]

mBio
This study explores virus-host dynamics in a unique environment: an industrial high-rate algal pond (HRAP). A wealth of novel DNA algal viruses are revealed, including members of Nucleocytoviricota “giant viruses” and the enigmatic Preplasmiviricota (e.g.

Infection signatures of multiple Nucleocytoviricota virus lineages in the brown algae Undaria pinnatifida revealed by population-wide genome analysis

Journal of Applied Phycology
Abstract Undaria pinnatifida is a large brown algae native to the northwest Pacific. It has been introduced to numerous countries and is listed among the world’s 100 worst invasive species. However, it is also edible and produces various bioactive compounds, making it commercially important.

20 years of research on giant viruses [PDF]

npj Viruses
Some twenty years ago, the discovery of the first giant virus, Acanthamoeba polyphaga mimivirus (now mimivirus bradfordmassiliense species), paved the way for the discovery of more than 10 new families of protist-infecting DNA viruses with unexpected ...
