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: 00.071.0.01.006. Virus accession number: 71001006. Obsolete virus code: 71.0.1.0.006; superceded accession number: 71010006.
NCBI Taxon Identifier NCBI Taxonomy ID: 35281.

Name, Synonyms and Lineage

Synonym(s): tobacco mosaic virus — P11 pepper isolate. ICTV approved acronym: PaMMV. Virus is an ICTV approved species of the genus 00.071.0.01. Tobamovirus; not assigned to a family.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is rod-shaped, straight with a clear modal length.

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

Physicochemical and Physical Properties

The infectivity is retained when deproteinized with phenol or detergent.

Nucleic Acid

The Mr of the genome constitutes 5% of the virion by weight. The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA. The complete genome is 6500 nucleotides long, is partially sequenced, sequenced region is 6500 nucleotides long. Sequence has the accession number [X72586] Gb(84)_vi:PMMVCP Paprika mild mottle virus (Pepper strain P11) coat protein gene and 3' non-coding region. 7/9.. Reference to nucleotide sequence Alonso et al. (1991).

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

Proteins constitute about 95% of the particle weight.

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

Lipids

Lipids are not reported.

Genome Organization and Replication

By itself, genomic nucleic acid is infectious.

Antigenicity

The virus does not show serological relationships to tobacco and Tomato mosaic viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

Class Magnoliopsida (Dicotyledonae)
Subclass ASTERIDAE.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation; possibly transmitted by seeds.

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 Leguminosae-Papilionoideae, Solanaceae. The following species were susceptible to experimental virus infection: Capsicum annuum, Capsicum frutescens, Nicotiana benthamiana, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana sylvestris, Nicotiana tabacum, Petunia x hybrida, Solanum melongena, Solanum pseudocapsicastrum, Trifolium subterraneum.

Host:
Experimentally infected hosts mainly show symptoms of small chlorotic or necrotic local lesions, mosaic and stunting.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Lycopersicon esculentum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Capsicum ssp. with either L+L+ or L1L1 genotypes — mild mottle or mosaic.

Nicotiana benthamiana — mosaic, stunting.

Nicotiana clevelandii — mosaic, malformation.

Solanum pseudocapsicastrum — mosaic.

Diagnostic host: insusceptible host species Lycopersicon esculentum.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Capsicum annuum, Nicotiana benthamiana and N. clevelandii.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Capsicum annuum (W), C. frutescens (L), Nicotiana clevelandii (W), N. sylvestris (L), N. tabacum cv Xanthi (L).

References to host data: Tobias et al. (1982).

Histopathology: Virus can be best detected in leaves. Virions are found in the cytoplasm.

Geographical Distribution

The virus spreads in Eurasia. The virus occurs in the Netherlands.
