Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.027.0.01.006. Virus accession number: 27001006. Obsolete virus code: 27.0.1.0.006; superceded accession number: 27010006.

Name, Synonyms and Lineage

ICTV approved acronym: SrCSV. Acronym(s): SgCSV. Virus is an ICTV approved species. Virus is of the genus 00.027.0.01. Furovirus; not assigned to a family.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. Virus preparations contain more than one particle component. The capsid is rod-shaped, straight with a clear modal length; with a length of 140 and 260 nm and a width of 20 nm. Axial canal is distinct.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Kendall et al. (1988).

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. Minor species of non-genomic nucleic acid are not found in virions. The complete genome is 9700 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 6200 nucleotides long, is sequenced and complete sequence is about 3500 nucleotides long. The 3'-terminus has no poly (A) tract. The multipartite genome is divided among more than one type of particle.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s).

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to wheat soil borne mosaic virus.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).

Class Liliopsida (Monocotyledonae)
Subclass COMMELINIDAE; Order Poales;
Family Poaceae. Virus found in Sorghum bicolor, Sorghum sudanense, Sorghum vulgare.

Transmission and Vector Relationships

A fungal vector is suspected. Virus is transmitted by mechanical inoculation.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Chenopodiaceae, Gramineae, Solanaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium quinoa, Nicotiana clevelandii, Sorghum bicolor, Zea mays.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium amaranticolor — chlorotic local lesions.

C. quinoa — ringspots.

Zea mays — elongated chlorotic spots.

Nicotiana clevelandii — yellowing and necrotic local lesions.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Zea mays.

Geographical Distribution

The virus is found, but with no evidence of proliferation, in Kansas, but not reported from other states in the U.S.A.
