Classification

This is a description of a plant virus at the species level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 00.077.0.01.014. Virus accession number: 77001014. Obsolete virus code: 77.0.1.0.152; superceded accession number: 77010152.
NCBI Taxon Identifier NCBI Taxonomy ID: 12153.

Name, Synonyms and Lineage

ICTV approved acronym: OYMV. Virus is an ICTV approved species of the genus 00.077.0.01. Tymovirus; family 00.077. Tymoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 25-30 nm. Capsids appear round. The capsomer arrangement is clearly visible.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Gibbs et al. (1966).

Physicochemical and Physical Properties

There are 2 sedimenting component(s) found in purified preparations. The sedimentation coefficient is of the fastest 114 S20w; of the other(s) are 56 S20w. Isoelectric point pH is 3.84. The thermal inactivation point (TIP) is at 65-70°C. The longevity in vitro (LIV) is 14 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3-5. The infectivity is not changed by treatment with ether.

Nucleic Acid

The Mr of the genome constitutes 34% of the virion by weight. The genome is monopartite. Only one particle size of linear, single-stranded RNA is recovered, is fully and partially sequenced. Sequence has the accession number

[J04375] Em(40)_vi:MTYCG Gb(84)_vi:OYMCG Ononis yellow mosaic virus complete genome. 6/90 6,211bp.
[M15287] Em(40)_vi:TYMTY3OY Gb(84)_vi:OYM3OYMV Ononis yellow mosaic virus 3' end which can form tRNA-like structure. 11/90 131bp.
[M58312] Em(40)_vi:OYMRRLS Gb(84)_vi:OYMRRLS Ononis yellow mosaic virus 3' terminus tRNA-like structure. 8/91 84bp. 3 sequences.
The genome has a base ratio of 15.6 % guanine; 21 % adenine; 34.2 % cytosine; 29.4 % uracil. Reference to nucleotide sequence Ding et al. (1990).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 66% of the particle weight.

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

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to scrophularia mottle is closely related; belladonna mottle and dulcamara mottle more distantly related; eggplant mosaic, Andean potato latent, wild cucumber mosaic and clitoria yellow vein viruses are very distantly related.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Class Magnoliopsida (Dicotyledonae)
Subclass ROSIDAE.

General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include chlorosis and development of patterns or markings that are visible in the intercostal regions. Intercostal regions show chlorosis. Leaves are turning yellow. Leaves with mosaic have yellow mosaic.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is not transmitted by a vector. Virus is transmitted by mechanical inoculation; not transmitted by grafting; not transmitted by seeds; not transmitted by pollen.

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 Leguminosae-Papilionoideae, Solanaceae. The following species were susceptible to experimental virus infection: Datura stramonium, Glycine max, Lycopersicon esculentum (cv. Kondine Red), Nicotiana clevelandii, Ononis repens, Pisum sativum, Trifolium incarnatum, Trifolium repens.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Apocynaceae, or Chenopodiaceae, Cucurbitaceae, Gramineae, Leguminosae-Papilionoideae, Solanaceae, Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Catharanthus roseus, Chenopodium amaranticolor, Chenopodium foetidum, Chenopodium quinoa, Cucumis sativus, Cucurbita pepo, Daucus carota, Gomphrena globosa, Hordeum vulgare, Medicago sativa, Nicotiana debneyi, Nicotiana glutinosa, Nicotiana rustica, Nicotiana tabacum, Pastinaca sativa, Petunia x hybrida, Phaseolus vulgaris, Triticum aestivum, Vicia faba, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Pisum sativum — system mosaic, stunting.

Trifolium incarnatum — systemic mosaic.

Datura stramonium — chlorotic local lesions, not systemic.

Nicotiana clevelandii — chlorotic local lesions, then systemic mottle. Diagnostic host: insusceptible host species Chenopodium quinoa, Phaseolus vulgaris, Vicia faba, Nicotiana glutinosa.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Pisum sativum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Pisum sativum (W), Trifolium incarnatum (W). No local lesion host known.

References to host data: Gibbs et al. (1966).

Histopathology: Virus can be best detected in all parts of the host plant. Virions are found in the cytoplasm.

Geographical Distribution

The virus occurs in the United Kingdom.
