Isolate Description

Location: England in plants imported from India; India (and isolated in England).

Host of Isolate and Habitat Details
Source of isolate: Solanum jasminoides.

Natural host and symptoms
Solanum jasminoides — symptoms unknown all the naturally infected plants examined also contained potato Y and tobacco wilt viruses.

Reference to Isolation Report
Badami and Kassanis (1959).

Classification

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

ICTVdB Virus Code: 00.057.0.81.028. Virus accession number: 57081028. Obsolete virus code: 57.0.1.T.028; superceded accession number: 5701t028.

Name, Synonyms and Lineage

ICTV approved acronym: DNV. 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 750 nm. Axial canal is indistinct. Basic helix is obscure.

Electron microscopic preparation and references: Virus preparation contains few virions.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 60-65°C. The longevity in vitro (LIV) is 8-12 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 4.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to potato Y and tobacco wilt 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).

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation.

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 Solanaceae. The following species were susceptible to experimental virus infection: Datura tatula, Hyoscyamus niger, Lycopersicon esculentum, Nicotiana glutinosa, Nicotiana tabacum, Physalis floridana, Solanum jasminoides.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Cucurbitaceae, or Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Cucumis sativus, Gomphrena globosa, Phaseolus vulgaris, Solanum tuberosum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Nicotiana tabacum — vein banding and mosaic.

Nicotiana glutinosa — mottling.

Datura tatula — local lesions and necrosis.

Solanum jasminoides — mottling.

Diagnostic host: insusceptible host species Solanum tuberosum, Cucumis sativus, Phaseolus vulgaris, Gomphrena globosa.

Maintenance and Propagation Hosts

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

Assay Hosts

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

Geographical Distribution

The virus occurs in India.
