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: 00.057.0.81.016. Virus accession number: 57081016. Obsolete virus code: 57.0.1.T.016; superceded accession number: 5701t016.
NCBI Taxon Identifier NCBI Taxonomy ID: 171230.

Name, Synonyms and Lineage

ICTV approved acronym: CeYMV. Virus is a tentative member 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 750 nm.

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 133 S20w. The thermal inactivation point (TIP) is at 55°C. The longevity in vitro (LIV) is 6 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 4.

Nucleic Acid

The Mr of the genome constitutes 5.5% of the virion by weight. 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

Proteins constitute about 94.5% of the particle weight.

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

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to celery mosaic 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 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, Umbelliferae. The following species were susceptible to experimental virus infection: Apium graveolens, Chenopodium amaranticolor, Chenopodium quinoa, Coriandrum sativum, Petroselinum crispum.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Caryophyllaceae, or Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, Gramineae, or Leguminosae-Caesalpinioideae, Leguminosae-Papilionoideae, Malvaceae, or Solanaceae, Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Abelmoschus esculentus, Beta vulgaris, Brassica campestris ssp. chinensis, Brassica juncea, Brassica oleracea var. botrytis, Brassica oleracea var. capitata, Calendula officinalis, Capsicum annuum, Cassia occidentalis, Chenopodium murale, Conium maculatum, Cucumis melo, Cucumis sativus, Cucurbita pepo, Dahlia pinnata, Datura stramonium, Daucus carota, Dianthus caryophyllus, Glycine max, Gomphrena globosa, Helianthus annuus, Lactuca sativa, Lycopersicon esculentum, Nicandra physalodes, Nicotiana debneyi, Nicotiana glutinosa, Nicotiana tabacum, Physalis floridana, Pisum sativum, Raphanus sativus, Solanum nigrum, Sonchus oleraceus, Spinacia oleracea, Vigna unguiculata, Zea mays, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Apium graveolens, Coriandrum sativum, Petroselinum crispum — systemic leaf chlorosis.

Chenopodium amaranticolor, C. quinoa — local lesions; no systemic infection.

Diagnostic host: insusceptible host species Conium maculatum, Datura stramonium, Glycine max, Gomphrena globosa, Nicotiana tabacum.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Apium graveolens, Coriandrum sativum, Petroselinum crispum.

Assay Hosts

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

References to host data: De Olivera and Kitajima (1981).

Histopathology: Virus can be best detected in leaves and mesophyll. Virions are found in the cytoplasm and nucleus.

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm and nucleus. Cytoplasmic inclusions are viroplasma and pinwheels. Inclusions are are fibrous proteinaceous nuclear inclusions.

Geographical Distribution

The virus occurs in Brazil.
