Classification

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

ICTVdB Virus Code: 00.057.0.81.014. Virus accession number: 57081014. Obsolete virus code: 57.0.1.T.014; superceded accession number: 5701t014.

Name, Synonyms and Lineage

ICTV approved acronym: CtMV. 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 740 nm and a width of 15 nm.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 65°C. The longevity in vitro (LIV) is 4 days (at 20-22°C). Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered.

Proteins

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

Lipids

Lipids are not reported.

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; Acyrthosiphon pisum, Cavariella aegopodii, Myzus persicae.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Chenopodiaceae, Leguminosae-Papilionoideae, Solanaceae, Umbelliferae. The following species were susceptible to experimental virus infection: Apium graveolens, Chenopodium amaranticolor, Chenopodium quinoa, Datura stramonium, Daucus carota, Lycopersicon esculentum, Medicago sativa, Phaseolus vulgaris, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Vigna unguiculata — chlorotic flecks and chlorosis of leaves.

Chenopodium quinoa — local chlorotic lesions.

Geographical Distribution

The virus occurs in Czechoslovakia (former).
