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: 00.057.0.01.019. Virus accession number: 57001019. Obsolete virus code: 57.0.1.0.019; superceded accession number: 57010019.
NCBI Taxon Identifier NCBI Taxonomy ID: 91613.

Name, Synonyms and Lineage

Synonym(s): Datura Colombian virus. ICTV approved acronym: CDV. Virus is an ICTV approved species. Virus is 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 ~28 721 nm.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Kahn and Bartels (1968).

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 55-60°C. The longevity in vitro (LIV) is 6 days (or more at 20-25°C in crude sap). Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5.

Nucleic Acid

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

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to henbane mosaic and tobacco etch viruses. The virus does not show serological relationships to potato A and Y viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

Severity and Occurrence of Disease

Host: Signs and symptoms persist, or disappear soon after infection.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation; transmitted by grafting.

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 Amaranthaceae, Solanaceae. The following species were susceptible to experimental virus infection: Datura candida, Datura metel, Datura sanguinea, Datura stramonium, Gomphrena globosa, Gomphrena globosa var. rubra, Nicotiana tabacum, Solanum demissum x S. tuberosum.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Capsicum annuum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Datura metel — wilting and death.

Nicotiana tabacum cv. Virginia — chlorotic and necrotic spots.

Nicotiana tabacum cv. Samsun — chlorotic or necrotic spots, veinal necrosis.

Solanum demissum x S. tuberosum 'A-6' — necrotic spots.

Datura stramonium — chlorotic spots, occasionally.

Gomphrena globosa var. rubra — red bordered local lesions.

Diagnostic host: insusceptible host species Capsicum annuum.

Maintenance and Propagation Hosts

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

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Datura metel (W, Nicotiana tabacum cv. Samsun (W).

References to host data: Kahn and Bartels (1968).

Geographical Distribution

The virus occurs in Colombia.
