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: 00.057.0.81.024. Virus accession number: 57081024. Obsolete virus code: 57.0.1.T.024; superceded accession number: 5701t024.
NCBI Taxon Identifier NCBI Taxonomy ID: 282712.

Name, Synonyms and Lineage

Synonym(s): daphne chlorotic mosaic Y virus. ICTV approved acronym: DVY. Virus is an ICTV approved species of the genus 00.057.0.01. Potyvirus; 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 733 nm and a width of 13 nm. Axial canal is indistinct. Basic helix is obscure.

Electron microscopic preparation and references: Reference for electron microscopic methods: Forster and Milne (1976).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 149 S20w. The thermal inactivation point (TIP) is at 65°C. The longevity in vitro (LIV) is 8-10 days (at 20°C). 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 does not show serological relationships to bean yellow mosaic, lettuce mosaic, maize dwarf mosaic, passionfruit woodiness, potato Y, tobacco etch, tamarillo mosaic, turnip mosaic and watermelon mosaic 2 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 a vector. Virus is transmitted by mechanical inoculation.

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, Solanaceae, Thymelaeaceae. The following species were susceptible to experimental virus infection: Chenopodium album, Chenopodium amaranticolor, Chenopodium quinoa, Daphne cneorum, Daphne mezereum, Daphne odora, Daphne retusa, Nicotiana clevelandii, Spinacia oleracea.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Caryophyllaceae, or Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, or Leguminosae-Caesalpinioideae, Leguminosae-Papilionoideae, or Scrophulariaceae, Solanaceae (3 /4). Species inoculated with virus that do not show signs of susceptibility: Antirrhinum majus, Beta vulgaris, Brassica campestris ssp. pekinensis, Cassia occidentalis, Cucumis melo, Cucumis sativus, Cucurbita maxima, Dianthus barbatus, Gomphrena globosa, Matthiola incana, Nicotiana glutinosa, Nicotiana tabacum, Petunia x hybrida, Phaseolus vulgaris, Pisum sativum, Vicia faba, Vigna unguiculata, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium album, C. amaranticolor, Spinacia oleracea — chlorotic and/or necrotic local lesions; no systemic infection.

Chenopodium quinoa — chlorotic local lesions; systemic chlorotic flecks or blotches.

Nicotiana clevelandii — symptomless local infection or etched necrotic rings; symptomless systemic infection.

Diagnostic host: insusceptible host species Cucumis sativus, Gomphrena globosa, Nicotiana tabacum, Phaseolus vulgaris, Vigna unguiculata.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Chenopodium quinoa.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chenopodium amaranticolor (L), C. quinoa (L).

References to host data: Forster and Milne (1976).

Histopathology: Virus can be best detected in leaves and mesophyll. 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. Inclusions do not contain mature virions.

Geographical Distribution

The virus occurs in Australia, the Netherlands, New Zealand (Aotearoa), and the United Kingdom.
