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]

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]
