Classification

This is a description of a plant virus at the strain level with data on all virus properties from morphology to genome, replication, antigenicity and biological properties.

ICTVdB Virus Code: 01.062.0.05.003.00.004. Virus accession number: 62005034. Obsolete virus code: 01.062.0.00.338.; 62.U.P.0.038; superceded accession number: 62000338; 62up0038.

Name, Synonyms and Lineage

ICTV approved acronym: PVCV. Acronym(s): PelVCV. Virus is assigned to the species 01.062.0.05.003. Eggplant mottle dwarf virus of the genus 01.062.0.05. Nucleorhabdovirus in the family 01.062. Rhabdoviridae; order 01. Mononegavirales.

Virion Properties

Morphology

Virions consist of an envelope and a nucleocapsid. Virus capsid is enveloped. Virions are bullet-shaped. Virions measure 70 nm in diameter (in sections), or 90 nm in diameter (purified virions, 250 nm in length (in sections), or 175 nm in length (purified virions). Capsid/nucleocapsid is elongated with helical symmetry. The nucleocapsid is uncoiled filamentous, or cylindrical (coiled). Axial canal is distinct; 30-35 nm in diameter. Basic helix is obvious.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 60°C. The longevity in vitro (LIV) is 2 days (at 22-24°C). Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 6.

Nucleic Acid

The genome is not segmented and contains a single molecule of linear single-stranded RNA.

Proteins

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

Replication cycle Virions accumulate in the cell nucleus.

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 ROSIDAE; Order Geraniales.

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 few families. Susceptible host species are found in the Family Amaranthaceae, Geraniaceae, Solanaceae. The following species were susceptible to experimental virus infection: Capsicum annuum, Gomphrena globosa, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana debneyi, Nicotiana glutinosa, Nicotiana megalosiphon, Nicotiana rustica, Nicotiana tabacum, Pelargonium peltatum, Pelargonium zonale, Petunia x hybrida.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Chenopodiaceae, Cucurbitaceae, or Leguminosae-Papilionoideae. Species inoculated with virus that do not show signs of susceptibility: Beta vulgaris, Chenopodium amaranticolor, Chenopodium quinoa, Cucumis sativus, Phaseolus vulgaris.

Diagnostic Hosts

Diagnostic host species and symptoms:

Nicotiana benthamiana, N. clevelandii, N. glutinosa, N. rustica, N. tabacum, N. debneyi, N. megalosiphon, Capsicum annuum, Petunia x hybrida — chlorotic or necrotic local lesions in older plants, but systemic vein clearing, chlorotic vein banding and leaf malformation of seedlings inoculated 4 leaf-stage.

Gomphrena globosa — small red local lesions; not systemic. Diagnostic host: insusceptible host species Chenopodium amaranticolor, C. quinoa, Cucumis sativus, Phaseolus vulgaris, Beta vulgaris.

Maintenance and Propagation Hosts

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

Assay Hosts

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

Histopathology: Virus can be best detected in leaves, mesophyll, vascular parenchyma and the phloem. Virions are found in the cytoplasm and perinuclear space.

Geographical Distribution

The virus occurs in Italy.
