Permutotetraviridae
Family of viruses
From Wikipedia, the free encyclopedia
Permutotetraviridae is a family of viruses. Lepidopteran insects serve as natural hosts. The family contains one genus that has two species. Diseases associated with this family include: infection outcome varies from unapparent to lethal. It was created by splitting Tetraviridae.[1][2]

Taxonomy
Permutotetraviridae has one genus which contains two species:[2]
- Genus: Alphapermutotetravirus
- Euprosterna elaeasa virus
- Thosea asigna virus
Structure
Viruses in Permutotetraviridae are non-enveloped, with icosahedral geometries, and T=4 symmetry. The diameter is around 40 nm. Genomes are linear, around 5.6kb in length.[1]
| Genus | Structure | Symmetry | Capsid | Genomic arrangement | Genomic segmentation |
|---|---|---|---|---|---|
| Alphapermutotetravirus | Icosahedral | T=4 | Non-enveloped | Linear | Monopartite |
Life cycle
Viral replication is cytoplasmic. Entry into the host cell is achieved by penetration into the host cell. Replication follows the positive stranded RNA virus replication model. Positive stranded RNA virus transcription is the method of transcription. Lepidopteran insectes serve as the natural host. Transmission routes are oral.[1]

Phylogenetic position
A 2020 Yangshan Port metagenomic study found that the Birnaviridae and Permutotetraviridae RdRPs fall into Pisuviricota near the Partitiviridae after correcting for domain permutation. This treatment was supported by the presence of alternative permutations in sampled metagenomes belonging to the same branch.[3]
