omegatetravirus omegatetravirus omegatetravirus is a genus of viruses, in the family alphatetraviridae. moths and butterflies serve as natural hosts. there are three species in this genus. infection outcome varies from unapparent to lethal. omegatetravirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: kitrinoviricota class: alsuviricetes order: hepelivirales family: alphatetraviridae genus: omegatetravirus taxonomy the following species are assigned to the genus: dendrolimus punctatus virus helicoverpa armigera stunt virus nudaurelia capensis omega virus structure viruses in omegatetravirus are non-enveloped, with icosahedral geometries, and t=4 symmetry. the diameter is around 40 nm. genomes are linear and bipartite, around 2.5kb in length. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation omegatetravirusicosahedralt=4non-envelopedlinearsegmented 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. translation takes place by leaky scanning. moths and butterflies serve as the natural host. transmission routes are oral. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission omegatetravirusmoths; butterfliesmidgutcell receptor endocytosisbuddingcytoplasmcytoplasmoral
