Classification

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

ICTVdB Virus Code: 00.000.4.00.003. Virus accession number: 00400003. Obsolete virus code: 00.079.0.74.001.; 79.0.P.4.DE.1; superceded accession number: 79074001; 790p4de1.

Name, Synonyms and Lineage

Virus is unclassified. Virus is not assigned to a genus; not assigned to a family.

Virion Properties

Morphology

Virions are not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is bacilliform with a length of 42 nm, 49 nm, or 76 nm and a width of 18 nm.

Electron microscopic preparation and references: Reference for electron microscopic methods: Fargette et al. (1991).

Physicochemical and Physical Properties

There are 3-4 sedimenting component(s) found in purified preparations. The thermal inactivation point (TIP) is at 55°C. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3.

Nucleic Acid

The Mr of the genome constitutes 25% of the virion by weight. The genome is segmented, tripartite (segements are distribute among 3 particle types of different size), and consists of three segments of single-stranded RNA. The complete genome is 9700 nucleotides long. The RNA-1 is sequenced, and complete sequence is about 3940 nucleotides long. RNA-2 is sequenced and complete sequence is about 3030 nucleotides long. RNA-3 is sequenced and complete is 2730 nucleotides long.

Proteins

Proteins constitute about 75% of the particle weight.

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to Alfalfa mosaic virus.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation.

Vector Transmission: Virus is not transmitted by Myzus persicae.

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 Amaranthaceae, Chenopodiaceae, Compositae, Euphorbiaceae, Leguminosae-Papilionoideae, Solanaceae, Tetragoniaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Gomphrena globosa, Manihot esculenta, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana rustica, Nicotiana tabacum, Petunia x hybrida, Phaseolus vulgaris, Senecio cruentus, Tetragonia tetragonioides.

Host:
Experimentally infected hosts mainly show symptoms of systemic chlorosis.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Apocynaceae, Compositae, Cruciferae, or Cucurbitaceae, Leguminosae-Papilionoideae, Solanaceae, Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Apium graveolens, Brassica campestris ssp. rapa, Catharanthus roseus, Coriandrum sativum, Cucumis sativus, Datura stramonium, Daucus carota, Lactuca sativa, Lycopersicon chilense, Lycopersicon esculentum, Nicotiana debneyi, Pastinaca sativa, Physalis floridana, Pisum sativum, Vicia faba, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium amaranticolor — slight distortion of young systemically infected leaves.

Chenopodium murale, C. quinoa — chlorotic or necrotic local lesions; systemic necrosis.

Gomphrena globosa, Tetragonia tetragonioides — chlorotic or necrotic local lesions; symptomless systemic infection.

Nicotiana benthamiana — symptomless or faint systemic mottle.

Nicotiana clevelandii, N. rustica, N. tabacum cv. Samsun,

Phaseolus vulgaris, Senecio cruentus — symptomless systemic infection. Diagnostic host: insusceptible host species Cucumis sativus, Datura stramonium, Nicotiana debneyi, Physalis floridana, Vigna unguiculata.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Chenopodium quinoa.

Assay Hosts

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

References to host data: Aiton et al. (1988).

Geographical Distribution

The virus occurs in Cote d'Ivoire.
