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: 00.065.0.02.002. Virus accession number: 65002002. Obsolete virus code: 65.0.2.0.002; superceded accession number: 65020002.

Name, Synonyms and Lineage

ICTV approved acronym: AYV. Virus is an ICTV approved species of the genus 00.065.0.02. Waikavirus; family 00.065. Sequiviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with polyhedral symmetry. The isometric capsid has a diameter of 29 nm. Capsids appear round. The capsomer arrangement is not obvious.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Hemida et al. (1989).

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.52 g cm-3 (B), or 1.27 g cm-3 (T). There are 2 sedimenting component(s) found in purified preparations. A260/A280 ratio is 1.83 (B), or 0.73 (T). The longevity in vitro (LIV) is purified virions in 1 mM CaCl2 or less remain intact for 45 days (at 4°C).

Nucleic Acid

The Mr of the genome constitutes 42% of the virion by weight (B), or 0% of the virion by weight (T). The genome is monopartite, only one particle size is recovered, linear, single-stranded RNA. The complete genome is 10600 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 10600 nucleotides long.

Proteins

Proteins constitute about 58% of the particle weight (B), or 100% of the particle weight (T).

The viral genome encodes structural proteins. Virions consist of 4 structural protein(s).

Lipids

Lipids are not reported.

Translation: Virions are associated with helper virus, but independent from its functions during replication. Virion acts as helper for another virus; a helper for Parsnip yellow fleck virus.

Antigenicity

The virus does not show serological relationships to maize chlorotic dwarf and rice tungro spherical 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).

Class Magnoliopsida (Dicotyledonae)
Subclass ROSIDAE.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is not transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Cavariella aegopodii. Virus is transmitted in a semi-persistent manner; can facilitate the vector transmission of another virus (parsnip yellow fleck virus).

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 Umbelliferae. The following species were susceptible to experimental virus infection: Anthriscus cerefolium, Anthriscus sylvestris, Coriandrum sativum.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Bupleurum rotundifolium, Daucus carota, Eryngium planum, Pastinaca sativa, Pimpinella anisum, Trinia glauca.

Diagnostic Hosts

Diagnostic host species and symptoms:

Anthriscus cerefolium — systemically infected leaves faintly chlorotic, then reddish purple and slightly distorted; plants stunted.

Coriandrum sativum — slight yellowing of systemically infected leaves; plants stunted.

Diagnostic host: insusceptible host species Bupleurum rotundifolium, Daucus carota, Eryngium planum, Pastinaca sativa, Pimpinella anisum, Trinia glauca.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Anthriscus cerefolium.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Anthriscus cerefolium (W).

References to host data: Murant and Goold (1968).

Histopathology: Virus can be best detected in phloem. Virions are found in the cytoplasm.

Cytopathology: Inclusions are not present in infected cells.

Geographical Distribution

The virus spreads in Eurasia. The virus occurs in the United Kingdom.
