Isolate Description

Location: Zimbabwe.

Host of Isolate and Habitat Details
Source of isolate: Nicotiana tabacum.

Natural host and symptoms
Nicotiana tabacum — malformation of leaf veins. Tobacco vein-distorting and tobacco mottle viruses together causes tobacco rosette disease.

Classification

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

ICTVdB Virus Code: 00.039.0.61.012. Virus accession number: 39061012. Obsolete virus code: 39.0.1.T.012; superceded accession number: 3901t012.
NCBI Taxon Identifier NCBI Taxonomy ID: 192203.

Name, Synonyms and Lineage

ICTV approved acronym: TVDV. Virus has not been assigned to a particular genus. Virus is of the genus 00.039.0.01. Luteovirus in the family 00.039. Luteoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The capsid.

Nucleic Acid

The genome is not segmented and contains a single molecule 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 absent.

Antigenicity

Few of the properties of this virus are known, but some indicate that it is probably a luteovirus (Waterhouse et al., 1988).

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 ASTERIDAE.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

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

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Myzus persicae, Acyrthosiphon (Aulacorthum) solani. Virus is transmitted in a persistent manner; can facilitate the vector transmission of another virus (tobacco mottle (?) virus).

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 Solanaceae. The following species were susceptible to experimental virus infection: Datura stramonium, Lycopersicon esculentum, Nicotiana glutinosa, Nicotiana sylvestris, Nicotiana tabacum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Nicotiana tabacum, N. glutinosa, N. sylvestris, Lycopersicon esculentum, Datura stramonium — leaf vein malformation.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Nicotiana tabacum, N. glutinosa, N. sylvestris.

Assay Hosts

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

References to host data: Smith (1946a).

Geographical Distribution

The virus occurs in Zimbabwe.

Ecology, Epidemiology and Control

Studies reported by Smith (1946a,b).

Comments

This virus was probably the first to be shown to assist the aphid transmission of another virus, tobacco mottle virus (Smith, 1946 a and b).
