Transcriptional dynamics during Heliothis zea nudivirus 1 infection in an ovarian cell line from .

Nudiviruses (family ) are double-stranded DNA viruses that infect various insects and crustaceans. Among them, Heliothis zea nudivirus 1 (HzNV-1) represents the rare case of a lepidopteran nudivirus inducing a sexual pathology. Studies about molecular pathological dynamics of HzNV-1 or other nudiviruses are scarce.

Nudiviruses in free-living and parasitic arthropods: evolutionary taxonomy.

The nudiviruses (family: Nudiviridae) are large double-stranded DNA (dsDNA) viruses that infect insects and crustaceans, and have most recently been identified from ectoparasitic members (fleas and lice). This virus family was created in 2014 and has since been expanded via the discovery of multiple novel viral candidates or accepted members, sparking the need for a new taxonomic and evolutionary overview. Using current information (including data from public databases), we construct a new comprehensive phylogeny, encompassing 49 different nudiviruses.

Processing of the capsid proteins of the Betachrysovirus Fusarium graminearum virus-China 9 (FgV-ch9).

While the capsid of viruses in the Alphachrysovirus genus is built of subunits of a single coat protein, the capsid of viruses grouped in the Betachrysovirus genus may consist of subunits of two different proteins. For four of these betachrysoviruses, the detected molecular weights of the putative coat proteins differ from the sizes deduced from the nucleic acid sequence. The origin of these modifications remained unclear and it was hypothesized that the coat proteins undergo unspecific degradation.
