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.

Hybrid sequencing reveals the genome of a Chrysochromulina parva virus and highlight its distinct replication strategy [PDF]

BMC Genomics
Chrysochromulina parva (C. parva) is a eukaryotic freshwater haptophyte algae found in lakes and rivers worldwide. It is known to be infected by viruses, yet knowledge of the diversity and activity of these viruses is still very limited.

Covariance of Marine Nucleocytoplasmic Large DNA Viruses with Eukaryotic Plankton Communities in the Sub-Arctic Kongsfjorden Ecosystem: A Metagenomic Analysis of Marine Microbial Ecosystems [PDF]

Microorganisms, 2023
Nucleocytoplasmic large DNA viruses (NCLDVs) infect various marine eukaryotes. However, little is known about NCLDV diversity and their relationships with eukaryotic hosts in marine environments, the elucidation of which will advance the current ...

Functional Profiling and Evolutionary Analysis of a Marine Microalgal Virus Pangenome [PDF]

Viruses, 2023
Phycodnaviridae are large double-stranded DNA viruses, which facilitate studies of host–virus interactions and co-evolution due to their prominence in algal infection and their role in the life cycle of algal blooms.

Phaeoviruses Present in Cultured and Natural Kelp Species, Saccharina latissima and Laminaria hyperborea (Phaeophyceae, Laminariales), in Norway [PDF]

Viruses, 2023
Phaeoviruses (Phycodnaviridae) are large icosahedral viruses in the phylum Nucleocytoviricota with dsDNA genomes ranging from 160 to 560 kb, infecting multicellular brown algae (Phaeophyceae).

New Isolates of Betachloroviruses Shed Light on the Diversity and Biological Complexity of an Unexplored Group of Giant Algal Viruses [PDF]

Viruses
The majority of giant algal viruses belong to the family Phycodnaviridae, class Algavirales, phylum Nucleocytoviricota. Among them, the genus Chlorovirus is the most studied, with three recognized groups based on genomics and host range, although many ...

Metavirome Insights into the Diversity and Potential Pathogenic Infection of Chlamys farreri in the Coastal Seas of the Republic of Korea [PDF]

Pathogens
Chlamys farreri is primarily cultivated in Japan, China, and South Korea. Although mass mortality of scallops has been occurring recently, likely caused by high temperatures or infectious diseases, the underlying cause remains unclear.

Evolution and Phylogeny of large DNA viruses, Mimiviridae and Phycodnaviridae including newly characterized Heterosigma akashiwo virus

Frontiers in Microbiology, 2016
Nucleocytoplasmic DNA viruses are a large group of viruses that harbor double-stranded DNA genomes with sizes of several hundred kbp, challenging the traditional concept of viruses as small, simple ‘organisms at the edge of life’.
