Nomenclature

Acronym

TVDV

ICTV decimal code

39.0.1.T.012

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Nicotiana tabacum - malformation of leaf veins. Tobacco vein-distorting and tobacco mottle viruses together causes tobacco rosette disease.

Transmission

Transmitted by a vector; an insect; Myzus persicae, Acyrthosiphon (Aulacorthum) solani; Aphididae. Transmitted in a persistent manner. Virus can help the vector transmission of another virus (tobacco mottle (?) umbravirus); not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants.

Ecology and control

Studies reported by Smith (1946a,b).

Geographical distribution

Spreads in Zimbabwe.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

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

Maintenance and propagation hosts

Nicotiana tabacum, N. glutinosa, N. sylvestris.

Assay hosts (Local lesions or Whole plants)

Nicotiana tabacum (W).

Susceptible host species

• Datura stramonium
• Lycopersicon esculentum
• Nicotiana glutinosa
• Nicotiana sylvestris
• Nicotiana tabacum

Families containing susceptible hosts

• Solanaceae (5/5)

Sources of host-range data

Smith (1946a).

Physical and biochemical properties

No data available.

Taxonomy and relationships

Probably Luteovirus

Additional comments on relationships

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

Comments and References

General comments

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