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

The GC% landscape of the Nucleocytoviricota. [PDF]
Braz J MicrobiolAbstract Genomic studies on sequence composition count with many different approaches, such as calculating the proportion of guanine and cytosine within a given sequence (GC% content), which can be associated with a variety of aspects of the organism’s biology. In this context, GC% can reveal clues on virus-host relationship and evolution. Here

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

20 years of research on giant viruses [PDF]
npj VirusesSome 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 ...

Adaptation strategies of giant viruses to low-temperature marine ecosystems. [PDF]
ISME JMicrobes in marine ecosystems have evolved their gene content to thrive successfully in the cold. Although this process has been reasonably well studied in bacteria and selected eukaryotes, less is known about the impact of cold environments on the ...

Time of day of infection shapes development of a eukaryotic algal-Nucleocytoviricota virocell. [PDF]
FEMS Microbiol EcolAbstract Aureococcus anophagefferens forms a model host-virus system with the “giant virus” Kratosvirus quantuckense. Studies to define its ribocell (uninfected) and virocell (virus-infected) forms are needed as these states co-occur during algal blooms.

Eukaryotic viruses encode the ribosomal protein eL40 [PDF]
npj VirusesViruses in the phylum Nucleocytoviricota are large, complex and have an exceptionally diverse metabolic repertoire. Some encode hundreds of products involved in the translation of mRNA into protein, but none was known to encode any of the proteins in ...
