victorivirus victorivirus victorivirus is a genus of viruses, in the family totiviridae. filamentous fungi serve as natural hosts. there are 14 species in this genus. victorivirus capsid structure of helminthosporium victoriae virus 190s (hvv190s) cryo-em of hvv190s virions. virus classification (unranked): virus realm: riboviria kingdom: orthornavirae phylum: duplornaviricota class: chrymotiviricetes order: ghabrivirales family: totiviridae genus: victorivirus structure viruses in victorivirus are non-enveloped, with icosahedral geometries, and t=2 symmetry. the diameter is around 40 nm. genomes are linear, around 4.6-6.7kb in length. the genome has 2 open reading frames. genusstructuresymmetrycapsidgenomic arrangementgenomic segmentation victorivirusicosahedralt=2non-envelopedlinear life cycle viral replication is cytoplasmic. entry into the host cell is achieved by virus remains intracellular. replication follows the double-stranded rna virus replication model. double-stranded rna virus transcription is the method of transcription. translation takes place by rna termination-reinitiation. the virus exits the host cell by cell to cell movement. filamentous fungi serve as the natural host. genushost detailstissue tropismentry detailsrelease detailsreplication siteassembly sitetransmission victorivirusfunginoneunknownunknowncytoplasmcytoplasmunknown taxonomy the genus victorivirus includes the following species: aspergillus foetidus slow virus 1 beauveria bassiana victorivirus 1 chalara elegans rna virus 1 coniothyrium minitans rna virus epichloe festucae virus 1 gremmeniella abietina rna virus l1 helicobasidium mompa totivirus 1-17 helminthosporium victoriae virus 190s magnaporthe oryzae virus 1 magnaporthe oryzae virus 2 rosellinia necatrix victorivirus 1 sphaeropsis sapinea rna virus 1 sphaeropsis sapinea rna virus 2 tolypocladium cylindrosporum virus 1
