tepovirus tepovirus tepovirus is a genus of viruses in the order tymovirales, in the family betaflexiviridae. plants as well as some other root and tuber crops in the andes serve as natural hosts. there are two species in this genus. tepovirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: kitrinoviricota class: alsuviricetes order: tymovirales family: betaflexiviridae subfamily: trivirinae genus: tepovirus taxonomy the following species are assigned to the genus: potato virus t prunus virus 1 structure viruses in tepovirus are non-enveloped, with flexuous and filamentous geometries. the diameter is around 12 nm. genomes are linear, around 6.5kb in length. the genome codes for 3 proteins. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation tepovirusfilamentousnon-envelopedlinearmonopartite 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. plants as well as some other root and tuber crops in the andes serve as the natural host. transmission routes are seed borne and pollen associated. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission tepoviruspome fruits; citrus; pearnoneviral movement; mechanical inoculationviral movementcytoplasmcytoplasmgrafting; propagating material
