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: 00.057.0.01.068. Virus accession number: 57001068. Obsolete virus code: 57.0.1.0.068; superceded accession number: 57010068.
NCBI Taxon Identifier NCBI Taxonomy ID: 12228.

Name, Synonyms and Lineage

ICTV approved acronym: TVMV. Virus is an ICTV approved species of the genus 00.057.0.01. Potyvirus in the family 00.057. Potyviridae.

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 clear modal length with a length of 765 nm and a width of 13 nm. Basic helix is obvious.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Sun et al. (1974).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. The thermal inactivation point (TIP) is at 60-70°C. The longevity in vitro (LIV) is 1-2 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 2-3.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered, is fully sequenced and partially sequenced. Sequence has the accession number

[K02991] Em(40)_vi:TVMURF Gb(84)_vi:TVMURF Tobacco vein mottling virus helper component-related P75 gene, partial cds. 4/90 420bp
[S68375] Em(40)_vi:S68375 Gb(84)_vi:S68375 coat protein (3' UTR region, direct repeats) tobacco vein mottling virus (TVMV), variant pXB
[X04083] Em(40)_vi:POTTVMVX Gb(84)_vi:POTTVMVX Tobacco vein mottling virus (TVMV) RNA genome. 9/93 9,472bp. 3 sequences.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Translation: The genome replicates in the cytoplasm.

Antigenicity

The virus does not show serological relationships to bean common mosaic, iris severe mosaic, clover yellow vein, henbane mosaic, peanut mottle, potato Y, soybean mosaic and tobacco etch 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).

Severity and Occurrence of Disease

Host: Signs and symptoms vary cyclically over a few weeks.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation; transmitted by grafting; transmitted by contact between hosts; not transmitted by pollen.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Myzus persicae. Virus is transmitted in a non-persistent manner.

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 Polygonaceae, Solanaceae. The following species were susceptible to experimental virus infection: Datura metel, Lycopersicon esculentum, Nicotiana glutinosa, Nicotiana tabacum, Rumex, Solanum carolinense.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Chenopodiaceae, or Cucurbitaceae, Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Capsicum annuum, Capsicum frutescens, Chenopodium amaranticolor, Cucumis sativus, Datura stramonium, Glycine max, Gomphrena globosa, Nicotiana clevelandii, Phaseolus vulgaris, Pisum sativum, Solanum tuberosum, Trifolium incarnatum, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Lycopersicon esculentum, Nicotiana glutinosa, N. tabacum — chlorotic vein banding.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Nicotiana tabacum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Nicotiana tabacum (W).

References to host data: Sun et al. (1974).

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

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Cytoplasmic inclusions are pinwheels. Inclusions do not contain mature virions.

Geographical Distribution

The virus spreads in North America.
