ICTV Virus Taxonomy Profiles

The family Botourmiaviridae includes viruses with a mono- or multi-segmented positive-sense RNA genome that infect plants and filamentous fungi. The family includes the genera Ourmiavirus (plant viruses), Botoulivirus, Betabotoulivirus, Magoulivirus, Scleroulivirus, Betascleroulivirus, Gammascleroulivirus, Deltascleroulivirus, Epsilonscleroulivirus, Penoulivirus, Rhizoulivirus and Betarhizoulivirus (fungal viruses). This summary is based on the International Committee on Taxonomy of Viruses (ICTV) Report on the family Botourmiaviridae, which is available at ictv.global/report/botourmiaviridae.

Phasmaviridae is a family for negative-sense RNA viruses with genomes of about 9.7–15.8 kb. These viruses are maintained in and/or transmitted by insects. Phasmavirids produce enveloped virions containing three single-stranded RNA segments that encode a nucleoprotein (N), a glycoprotein precursor (GPC), and a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Phasmaviridae, which is available at ictv.global/report/phasmaviridae.

Members of the family Fimoviridae are plant viruses with a multipartite negative-sense enveloped RNA genome (−ssRNA), composed of 4–10 segments comprising 12.3–18.5 kb in total, within quasi-spherical virions. Fimoviruses are transmitted to plants by eriophyid mites and induce characteristic cytopathologies in their host plants, including double membrane-bound bodies in the cytoplasm of virus-infected cells. Most fimoviruses infect dicotyledonous plants, and many cause serious disease epidemics. This is a summary of the ICTV Report on the family Fimoviridae, which is available at ictv.global/report/fimoviridae.

Hantaviridae is a family for negative-sense RNA viruses with genomes of about 10.5–14.6 kb. These viruses are maintained in and/or transmitted by fish, reptiles, and mammals. Several orthohantaviruses can infect humans, causing mild, severe, and sometimes-fatal diseases. Hantavirids produce enveloped virions containing three single-stranded RNA segments with open reading frames that encode a nucleoprotein (N), a glycoprotein precursor (GPC), and a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Hantaviridae, which is available at ictv.global/report/hantaviridae.

Filoviridae is a family of negative-sense RNA viruses with genomes of about 13.1–20.9 kb that infect fish, mammals and reptiles. The filovirid genome is a linear, non-segmented RNA with five canonical open reading frames (ORFs) that encode a nucleoprotein (NP), a polymerase cofactor (VP35), a glycoprotein (GP1,2), a transcriptional activator (VP30) and a large protein (L) containing an RNA-directed RNA polymerase (RdRP) domain. All filovirid genomes encode additional proteins that vary among genera. Several filovirids (e.g., Ebola virus, Marburg virus) are pathogenic for humans and highly virulent. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Filoviridae, which is available at www.ictv.global/report/filoviridae.

Cruliviridae is a family of negative-sense RNA viruses with genomes of 10.8–11.5 kb that have been found in crustaceans. The crulivirid genome consists of three RNA segments with ORFs that encode a nucleoprotein (NP), a glycoprotein (GP), a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain, and in some family members, a zinc-finger (Z) protein of unknown function. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Cruliviridae, which is available at ictv.global/report/cruliviridae.

Jingchuvirales is an order of negative-sense RNA viruses with genomes of 9.1–15.3 kb that have been associated with arachnids, barnacles, crustaceans, insects, fish and reptiles in Africa, Asia, Australia, Europe, North America and South America. The jingchuviral genome has two to four open reading frames (ORFs) that encode a glycoprotein (GP), a nucleoprotein (NP), a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain, and/or proteins of unknown function. Viruses in the order are only known from their genome sequences. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the order Jingchuvirales and on the families Aliusviridae, Chuviridae, Crepuscuviridae, Myriaviridae and Natareviridae, which are available at ictv.global/report/jingchuvirales, ictv.global/report/aliusviridae, ictv.global/report/chuviridae, ictv.global/report/crepuscuviridae, ictv.global/report/myriaviridae and ictv.global/report/natareviridae, respectively.

Mypoviridae is a family of negative-sense RNA viruses with genomes of about 16.0 kb that have been found in myriapods. The mypovirid genome consists of three monocistronic RNA segments that encode a nucleoprotein (NP), a glycoprotein (GP), and a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Mypoviridae, which is available at: ictv.global/report/mypoviridae.

Wupedeviridae is a family of negative-sense RNA viruses with genomes of about 20.5 kb that have been found in myriapods. The wupedevirid genome consists of three monocistronic RNA segments with open reading frames (ORFs) that encode a nucleoprotein (NP), a glycoprotein (GP), and a large (L) protein containing an RNA-directed RNA polymerase (RdRP) domain. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Wupedeviridae, which is available at ictv.global/report/wupedeviridae.

Amnoonviridae is a family of negative-sense RNA viruses with genomes totalling about 10.3 kb. These viruses have been found in fish. The amnoonvirid genome consists of 10 segments, each with at least 1 open reading frame (ORF). The RNA1–3 ORFs encode the three subunits of the viral polymerase. The RNA4 ORF encodes a nucleoprotein. This is a summary of the International Committee on Taxonomy of Viruses (ICTV) Report on the family Amnoonviridae, which is available at ictv.global/report/amnoonviridae.
