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: 00.056.0.01.026. Virus accession number: 56001026. Obsolete virus code: 00.056.0.71.002.; 56.0.1.DE.02; superceded accession number: 56071002; 5601de02.
NCBI Taxon Identifier NCBI Taxonomy ID: 28354.

Name, Synonyms and Lineage

The taxon has the accepted ICTV name.

Virus is an ICTV approved species of the genus 00.056.0.01. Potexvirus in the family 00.056. Flexiviridae.

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 length of 490-530 nm and a width of 11 nm. Axial canal is indistinct.

Electron microscopic preparation and references: Reference for electron microscopic methods: Solovyev et al. (1994).

Nucleic Acid

The Mr of the genome constitutes 6% of the virion by weight. The genome is monopartite, only one particle size is recovered of linear, positive-sense, single-stranded RNA. Minor species of non-genomic nucleic acid are also found in virions. The encapsidated nucleic acid is mainly of genomic origin, but virions may also contain subgenomic RNA. The complete genome is 6128 nucleotides long. Sequence is fully and partially sequenced. Complete sequence is 6128 nucleotides long. Sequence has the accession number
[S61526] Em(40)_vi:S61526 Gb(84)_vi:S61526 triple block genes: putative helicase...13 kda putative membrane-associated protein Plantago
[Z21647] Em(40)_vi:PARNASQ Gb(84)_vi:PARNASQ P.asiatica mosaic virus genomic RNA. 2/94 6,128bp. 2 sequences.

The genome has an intergenic poly (A) region at 3' terminus.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 94% of the particle weight.

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

Structural Proteins: Reference to method of preparation: Solovyev et al., 1994.

Non-Structural Proteins: Virus-coded non-structural proteins have been isolated and 1 non-structural protein(s) are found (170 kDa).

Lipids

Lipids are not reported.

Transcription: The virus codes for 5 ORF(s).

Sub-genomic RNA is present in infected cells; encoding the coat protein.

Coding Strategy of Segment 1: Sequence has a gene block. Sequence has triple gene block sequence (TGB). Encodes proteins involved in cell to cell movement.

General Symptoms in Plants Symptoms mosaic.

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation.

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in many families. Susceptible host species are found in the Family Plantaginaceae. The following species were susceptible to experimental virus infection: Plantago asiatica.

Host:
Experimentally infected hosts mainly show symptoms of mosaic.
