Classification

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

ICTVdB Virus Code: 00.015.0.85.001. Virus accession number: 15085001. Obsolete virus code: 15.0.5.T.001; 07.0.01.T.001; superceded accession number: 1505t001; 0701t001.

Name, Synonyms and Lineage

Synonym(s): Aucuba ringspot virus. ICTV approved acronym: AuBV. Virus is a tentative member. Virus is of the genus 00.015.0.05. Badnavirus in the family 00.015. Caulimoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid is elongated and exhibits icosahedral symmetry. The capsid is bacilliform. The capsid shells of virions are composed of multiple layers. With a length of c. 130 nm and a width of 30 nm.

Electron microscopic preparation and references: Virus preparation contains few virions.

Nucleic Acid

The genome is not segmented and contains a single molecule of circular. The genome is -RT. The genome is double-stranded DNA. The genome has terminally redundant sequences. The terminally redundant sequences have direct terminal repeats; are reiterated internally in inverted form.

Proteins

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

Non-Structural Proteins: The virus codes for an RNA-dependent DNA polymerase.

Lipids

Lipids are not reported.

Transcription: The virus codes for 3 ORF(s).

Translation: Replication involves a reverse transcription step.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

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

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between hosts; not transmitted by seeds; not transmitted by pollen.

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 Aucubaceae. The following species were susceptible to experimental virus infection: Aucuba japonica.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Apocynaceae, or Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, Gramineae, or Leguminosae-Papilionoideae, Solanaceae, Tetragoniaceae (1 /1), or Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Beta vulgaris, Brassica campestris ssp. pekinensis, Brassica oleracea var. botrytis, Catharanthus roseus, Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Cucumis melo, Cucumis sativus, Datura stramonium, Daucus carota, Glycine max, Gomphrena globosa, Hordeum vulgare, Lactuca sativa, Lycopersicon esculentum, Nicotiana glutinosa, Nicotiana rustica, Nicotiana tabacum, Oryza sativa, Petunia x hybrida, Phaseolus vulgaris, Pisum sativum, Raphanus sativus, Solanum melongena, Spinacia oleracea, Tetragonia tetragonioides, Trifolium repens, Triticum aestivum, Vicia faba, Vigna unguiculata, Zea mays.

Diagnostic Hosts

Diagnostic host species and symptoms:
Aucuba japonica — yellow spots and mosaic.

Histopathology: Virus can be best detected in the leaves and all parts of the host plant. Virions are found in the cytoplasm.

Cytopathology: Inclusions are not present in infected cells.

Geographical Distribution

The virus is found, but with no evidence of proliferation, in Japan and the U.K.

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Caulimoviridae at the meeting in Strasburg, April 1997. The proposal has been approved at the meeting of the Executive Committee in Strasburg, 1997, the taxon has been removed from the Species (Badnavirus).
