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: 00.017.0.02.005. Virus accession number: 17002005. Obsolete virus code: 17.0.1.T.3.05; superceded accession number: 1701t305.
NCBI Taxon Identifier NCBI Taxonomy ID: 31713.

Name, Synonyms and Lineage

ICTV approved acronym: LIYV. Virus is an ICTV approved species of the genus 00.017.0.02. Crinivirus in the 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 with a length of 1800-2000 nm and a width of 13-14 nm.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Duffus et al. (1986).

Nucleic Acid

The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, positive-sense, single-stranded RNA. The complete genome is 15311 nucleotides long. The RNA-1 is fully sequenced, complete sequence is 8118 nucleotides long and encodes methyltransferase and RNA-dependent RNA polymerase genes. Sequence has the accession number [U15440] Em(43)_vi:Li15440 Gb(89)_vi:Liu15440 gi:64198.

RNA-2 is fully sequenced, complete sequence is 7193 nucleotides long and encodes heat-shock protein, coat protein, and duplicated coat protein genes has the accession number [U15441] Em(43)_vi:Li15441 Gb(89)_vi:Liu15441 gi:641984.

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 beet pseudoyellows virus.

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.

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

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in many families (45 ssp. in 15 families). Susceptible host species are found in the Family Caryophyllaceae, Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, Leguminosae-Papilionoideae, Malvaceae, Solanaceae, Tropaeolaceae, Umbelliferae. The following species were susceptible to experimental virus infection: Beta macrocarpa, Beta vulgaris, Brassica campestris ssp. pekinensis, Brassica campestris ssp. rapa, Capsella bursa-pastoris, Carthamus tinctorius, Chenopodium capitatum, Chenopodium murale, Chenopodium quinoa, Cichorium endiva, Citrullus lanatus, Cucumis melo, Cucumis sativus, Cucurbita maxima, Cucurbita moschata, Cucurbita pepo, Daucus carota, Dianthus caryophyllus, Helianthus annuus, Lactuca sativa, Malva parviflora, Nicotiana clevelandii, Petunia x hybrida, Pisum sativum, Raphanus sativus, Sonchus oleraceus, Spinacia oleracea, Trifolium subterraneum, Tropaeolum majus, Zinnia elegans.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Alliaceae, Compositae, Cruciferae, or Labiatae, Leguminosae-Papilionoideae, Malvaceae, Pedaliaceae, or Solanaceae, Umbelliferae (1 /2). Species inoculated with virus that do not show signs of susceptibility: Abelmoschus esculentus, Allium cepa, Bellis perennis, Brassica campestris ssp. napus, Brassica oleracea var. botrytis, Capsicum annuum, Coriandrum sativum, Cyamopsis tetragonoloba, Datura metel, Datura stramonium, Gossypium hirsutum, Lycopersicon esculentum, Medicago sativa, Nicandra physalodes, Nicotiana tabacum, Ocimum basilicum, Phaseolus vulgaris, Physalis floridana, Sesamum indicum, Vicia faba.

Diagnostic Hosts

Diagnostic host species and symptoms:
Beta vulgaris, Chenopodium quinoa, Lactuca sativa, Brassica campestris ssp. pekinensis, Citrullus lanatus, Cucumis melo, Cucumis sativus, Trifolium subterraneum, Malva parviflora, Nicotiana clevelandii — severe chlorosis, and/or reddening, rolling, vein-clearing and brittleness of leaves; stunting. Diagnostic host: insusceptible host species Capsicum annuum, Nicotiana tabacum, Phaseolus vulgaris, Vicia faba, Datura stramonium.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Lactuca sativa, Malva parviflora, Nicotiana clevelandii.

Assay Hosts

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