Classification

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

ICTVdB Virus Code: 00.057.0.81.036. Virus accession number: 57081036. Obsolete virus code: 57.0.1.T.036; superceded accession number: 5701t036.
NCBI Taxon Identifier NCBI Taxonomy ID: 291286.

Name, Synonyms and Lineage

ICTV approved acronym: EuRV. 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.

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.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

General Symptoms in Plants Symptoms chlorotic spots, leaf and flower malformation.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

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 Chenopodiaceae, Euphorbiaceae. The following species were susceptible to experimental virus infection: Chenopodium quinoa, Euphorbia loricata, Euphorbia milii, Euphorbia milii x E. lophogona.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Solanaceae, Tetragoniaceae. Species inoculated with virus that do not show signs of susceptibility: Datura stramonium, Gomphrena globosa, Nicotiana clevelandii, Nicotiana glutinosa, Tetragonia tetragonioides.

Diagnostic Hosts

Diagnostic host species and symptoms:

Euphorbia milii x E. lophogona — chlorotic spots, leaf and flower malformation.

Chenopodium quinoa Danish isolate — local white rings, not systemic.

Euphorbia milii — chlorotic ringspots.

Diagnostic host: insusceptible host species Datura stramonium, Gomphrena globosa, Nicotiana clevelandii, N. glutinosa, Tetragonia tetragonioides.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Euphorbia milii, E. milii x E. lophogona.

Histopathology: Virus can be best detected in leaves and epidermis. 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.

Geographical Distribution

The virus is found, but with no evidence of proliferation, in Germany and Denmark.
