Classification

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

ICTVdB Virus Code: 00.071.0.01.009. Virus accession number: 71001009. Obsolete virus code: 71.0.1.0.009; superceded accession number: 71010009.

Name, Synonyms and Lineage

Synonym(s): Opuntia Sammons' virus. ICTV approved acronym: SOV. Virus is an ICTV approved species. Virus is of the genus 00.071.0.01. Tobamovirus; 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. The capsid is rod-shaped, straight with a clear modal length with a length of 317 nm and a width of 18 nm. Axial canal is distinct. Basic helix is obvious.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Wetter: clarify with chloroform—butanol (1:1 v/v), precipitate with 4% polyethylene glycol and 4% NaCl, resuspend and subject to several cycles of differential centrifugation.

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 196 S20w. A260/A280 ratio is 1.33.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to Odontoglossum ringspot, Tomato mosaic, tobacco mosaic, ribgrass mosaic, tobacco mild green mosaic, pepper mild mottle, Sunn-hemp mosaic, Frangipani mosaic and Cucumber green mottle mosaic viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in few families. Susceptible host species are found in the Family Cactaceae, Chenopodiaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Opuntia engelmannii.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium quinoa, C. murale, C. amaranticolor — local lesions; not systemic.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Chenopodium quinoa, C. murale, C. amaranticolor.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chenopodium quinoa (L), C. murale (L), C. amaranticolor (L).

References to host data: Wetter and Paul (1967).

Geographical Distribution

The virus occurs in the United States of America.
