Name, Synonyms and Lineage

Synonym(s): Commelina yellow mottle virus group. Virus is of 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 95-130 nm, or 60-900 nm and a width of 24-30-35 nm.

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

Physicochemical and Physical Properties

Virions have a buoyant density in CsCl of 1.31 g cm-3. There are 1 sedimenting component(s) found in purified preparations. The sedimentation coefficient is 218-251.5-285 S20w. The thermal inactivation point (TIP) is at 55-57.5-60°C. The longevity in vitro (LIV) is 28-56.5-85 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3-4.

Nucleic Acid

The genome is not segmented and contains a single molecule of circular. The genome is -RT. The genome is double-stranded DNA that forms an open circle. The complete genome is 7200-76000 nucleotides long, is sequenced, complete sequence is about 7200-7600 nucleotides long. The genome has a guanine + cytosine content of 39.6-44.1 %. The genome has terminally redundant sequences. The terminally redundant sequences have direct terminal repeats; are reiterated internally in inverted form.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s).

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 Magnoliopsida (Dicotyledonae) and Liliopsida (Monocotyledonae).

Severity and Occurrence of Disease

Host: Signs and symptoms persist, or vary seasonally, or disappear soon after infection.

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation, or not transmitted by mechanical inoculation; transmitted by grafting, or not transmitted by grafting; not transmitted by contact between hosts; transmitted by seeds, or not transmitted by seeds; transmitted by pollen to the seed, or not transmitted by pollen.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aleyrodidae, Aphididae, Cicadellidae, Pseudococcidae. Virus is transmitted in a semi-persistent manner, or in a persistent manner; retained when the vector moults, or lost by the vector when it moults; does not replicate in the vector; not transmitted congenitally to the progeny of the vector; requires, for vector transmission, a helper virus.
