Classification

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

ICTVdB Virus Code: 00.015.0.05.004. Virus accession number: 15005004. Obsolete virus code: 15.0.5.0.004; 07.0.1.0.004; superceded accession number: 15050004; 07010004.

Name, Synonyms and Lineage

Synonym(s): canna mottle virus. ICTV approved acronym: CaYMV. Virus is an ICTV approved species. Virus is of the genus 00.015.0.05. Badnavirus in the family 00.015. Caulimoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid is elongated and exhibits icosahedral symmetry. The capsid is bacilliform. The capsid shells of virions are composed of multiple layers. With a length of 120-130 nm and a width of 28 nm.

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

Nucleic Acid

The genome is not segmented and contains a single molecule of circular. The genome is -RT. The genome is double-stranded DNA. The genome has terminally redundant sequences. The terminally redundant sequences have direct terminal repeats; are reiterated internally in inverted form.

Proteins

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

Non-Structural Proteins: The virus codes for an RNA-dependent DNA polymerase.

Lipids

Lipids are not reported.

Transcription: The virus codes for 3 ORF(s).

Translation: Replication involves a reverse transcription step.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).

Class Liliopsida (Monocotyledonae)
Subclass ZINGIBERIDAE.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Cannaceae. The following species were susceptible to experimental virus infection: Canna.

Host:
Experimentally infected hosts mainly show symptoms of chlorosis, mottle.

Diagnostic Hosts

Diagnostic host species and symptoms:

Canna ssp. — systemic veinal mottling and chlorosis.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Canna ssp.

Histopathology: Virus can be best detected in vascular parenchyma. 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 membranous bodies. Inclusions contain mature virions.

Geographical Distribution

The virus occurs in Japan and the United States of America.

Taxonomic Proposals and Changes

A taxonomic proposal has been submitted to the ICTV by the Plant Virus Subcommittee, Study Group for Caulimoviridae at the meeting in Strasburg, April 1997. The proposal has been approved at the meeting of the Executive Committee in Strasburg, 1997, the taxon has been removed from the Species (Badnavirus).
