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: 00.049.0.03.001. Virus accession number: 49003001. Obsolete virus code: 49.0.3.0.001; superceded accession number: 49030001.
NCBI Taxon Identifier NCBI Taxonomy ID: 292052.

Name, Synonyms and Lineage

Synonym(s): red clover cryptic virus 1. ICTV approved acronym: WCCV-1. Virus is the type species of the genus Alphacryptovirus ; family 00.049. Partitiviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The nucleocapsid is isometric and has a diameter of 30 nm. Capsids appear round.

Nucleic Acid

The Mr of the genome constitutes 25% of the virion by weight. The genome is segmented; bipartite, segements are distributed among 2 particle types of linear, double-stranded RNA. The complete genome is 6500 nucleotides long. The multipartite genome is possible packaged in one particle, but it is not known whether they are packaged together or separately.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes 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).

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation; not transmitted by grafting; transmitted by seeds.

Experimental Hosts and Symptoms

Susceptible host species are found in the Family Leguminosae-Papilionoideae. The following species were susceptible to experimental virus infection: Trifolium repens.

Geographical Distribution

The virus is found, but with no evidence of proliferation, in Japan.

Comments

White clover temperate virus (Natsuaki et al. (1984) is a mixture of white clover cryptic viruses 1, 2 and 3 (Natsuaki et al. (1986).
