Classification

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

ICTVdB Virus Code: 00.057.0.81.021. Virus accession number: 57081021. Obsolete virus code: 57.0.1.T.021; superceded accession number: 5701t021.

Name, Synonyms and Lineage

ICTV approved acronym: CriMV. Virus is an ICTV approved species of the genus 00.057.0.01. Potyvirus in the 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 780 nm and a width of 11 nm. Axial canal is indistinct. Basic helix is obscure.

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

Physicochemical and Physical Properties

Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 2-4.

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 Liliopsida (Monocotyledonae).

General Symptoms in Plants Symptoms longitudinal streaking, yellow mosaic and general chlorosis.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

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 Amaryllidaceae. The following species were susceptible to experimental virus infection: Crinum.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Chenopodiaceae, or Cucurbitaceae, Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Capsicum annuum, Chenopodium amaranticolor, Chenopodium quinoa, Cucumis sativus, Datura metel, Datura stramonium, Gomphrena globosa, Lycopersicon esculentum, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana rustica, Nicotiana sylvestris, Nicotiana tabacum, Physalis peruviana, Trifolium subterraneum, Vicia faba, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host: insusceptible host species Chenopodium quinoa, Capsicum annuum, Nicotiana clevelandii, Vicia faba, Lycopersicon esculentum.

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

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Cytoplasmic inclusions are pinwheels. Inclusions are and tubular structures. Inclusions contain mature virions. Other cellular changes include pinwheel and tubular inclusions, large masses of virions, nuclei with invaginations containing mitochondria.

Geographical Distribution

The virus occurs in Australia and Fiji (Brunt, 1980).
