Classification

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

ICTVdB Virus Code: 00.017.0.02.008. Virus accession number: 17002008. Obsolete virus code: 17.0.1.T.DE.6; superceded accession number: 1701tde6.
NCBI Taxon Identifier NCBI Taxonomy ID: 52135.

Name, Synonyms and Lineage

Virus is an ICTV approved species of the genus Crinivirus; family 00.017. Closteroviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous, flexuous with a length of 850-900 nm and a width of 12 nm.

Electron microscopic preparation and references: Reference for electron microscopic methods: Duffus (1995).

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to Beet pseudo yellows virus, Lettuce infectious yellows and Cucurbit yellow stunt virus.

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 a vector. Virus is not transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aleyrodidae; Trialeurodes vaporariorum. Virus is not transmitted by Bemisia ssp.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in several families. Susceptible host species are found in the Family Compositae, Solanaceae. The following species were susceptible to experimental virus infection: Lactuca sativa, Lycopersicon esculentum, Petunia x hybrida, Solanum tuberosum, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:
Lycopersicon esculentum — interveinal yellowing, necrosis and stunting.

Geographical Distribution

The virus occurs in possibly Italy and the United States of America.

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Closteroviridae at the meeting in San Diego, March 1998, to change the position of the taxon. The proposal has been approved at the meeting of the Executive Committee in San Diego, 1998, the taxon has been designated as Species (in the newly created Genus Crinivirus).
