citrivirus citrivirus citrivirus is a genus of viruses in the order tymovirales, in the family betaflexiviridae. plants serve as natural hosts. there is only one species in this genus: citrus leaf blotch virus. citrivirus virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: kitrinoviricota class: alsuviricetes order: tymovirales family: betaflexiviridae subfamily: trivirinae genus: citrivirus structure viruses in citrivirus are non-enveloped, with flexuous and filamentous geometries. the diameter is around 12 nm, with a length of 960 nm. genomes are linear, around 8.7kb in length. the genome has 3 open reading frames. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation citrivirusfilamentousnon-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 serve as the natural host. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission citrivirusplantsnoneviral movement; mechanical inoculationviral movementcytoplasmcytoplasmunknown
