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: 00.017.0.02.010. Virus accession number: 17002010. Obsolete virus code: 00.017.0.82.010.; 00.017.0.01.002.; 17.0.1.T.3.01; superceded accession number: 17082010; 17001002; 1701t301.
NCBI Taxon Identifier NCBI Taxonomy ID: 43259.

Name, Synonyms and Lineage

Synonym(s): cucumber yellows virus (Yamashita et al., 1979), muskmelon yellows virus (Liu and Duffus, 1990; Lot et al., 1982). ICTV approved acronym: BPYV. Virus is a tentative member of the genus Crinivirus; family 00.017. Closteroviridae.

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.

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA.

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

Beet pseudo-yellows virus seems similar to cucumber yellows virus, from Japan and also transmitted by Trialeurodes vaporariorum, but has a host range restricted to cucurbits and has flexuous virions of c. 1000 nm long (Yamashita et al., 1979).

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 transmitted by a vector. Virus is not transmitted by mechanical inoculation; not transmitted by contact between hosts; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aleyrodidae; Trialeurodes vaporariorum. Virus is transmitted in a semi-persistent manner; does not replicate in the vector; not transmitted congenitally to the progeny of the vector.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in many families. Susceptible host species are found in the Family Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, Geraniaceae, Linaceae, Malvaceae, Portulacaceae, Ranunculaceae, Solanaceae, Umbelliferae, Urticaceae. The following species were susceptible to experimental virus infection: Aquilegia, Beta macrocarpa, Beta vulgaris, Callistephus chinensis, Capsella bursa-pastoris, Chenopodium album, Chenopodium amaranticolor, Chenopodium capitatum, Chenopodium murale, Cichorium endiva, Conium maculatum, Cucumis melo, Cucumis sativus, Cucurbita moschata, Daucus carota, Erodium cicutarium, Geranium dissectum, Lactuca sativa, Linum grandiflorum, Linum usitatissimum, Malva parviflora, Montia perfoliata, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana tabacum, Physalis ixocarpa, Physalis wrightii, Senecio vulgaris, Solanum dulcamara, Sonchus oleraceus, Spinacia oleracea, Taraxacum officinale, Urtica californica, Zinnia elegans.

Host:
Experimentally infected hosts mainly show symptoms of yellowing, reddening, curling.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Compositae, Convolvulaceae, Cruciferae, or Cucurbitaceae, Leguminosae-Papilionoideae, Malvaceae, Solanaceae, or Tetragoniaceae. Species inoculated with virus that do not show signs of susceptibility: Abelmoschus esculentus, Althaea rosea, Citrullus lanatus, Cucurbita pepo, Datura stramonium, Gossypium hirsutum, Helianthus annuus, Ipomoea nil, Ipomoea purpurea, Ipomoea tricolor, Lavatera assurgentiflora, Lycopersicon esculentum, Malva sylvestris, Medicago sativa, Nicandra physalodes, Phaseolus vulgaris, Physalis floridana, Raphanus sativus, Sisymbrium irio, Tetragonia tetragonioides, Thlaspi arvense.

Diagnostic Hosts

Diagnostic host species and symptoms:

Beta vulgaris, Capsella bursa-pastoris, Lactuca sativa — yellowing, thickening, brittleness of leaves.

Taraxacum officinale, Chenopodium capitatum — interveinal reddening and chlorosis.

Linum usitatissimum, Nicotiana glutinosa, Cucumis melo — interveinal yellowing.

Diagnostic host: insusceptible host species Datura stramonium, Lycopersicon esculentum, Physalis floridana, Tetragonia tetragonioides.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Closteroviridae, to change the position of the taxon. The proposal has been approved, the taxon has been removed from the Genus Closterovirus. The taxon has been accepted as species in the Genus Crinivirus.
