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: 00.071.0.81.017. Virus accession number: 71081017. Obsolete virus code: 71.0.1.T.016; superceded accession number: 7101t016.

Name, Synonyms and Lineage

ICTV approved acronym: MarMV. Virus is a tentative member 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 with a length of 304 nm and a width of 18 nm. Axial canal is distinct.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Fribourg et al. (1987, Fribourg and Nakashima (1984).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations. The thermal inactivation point (TIP) is at 90°C. The longevity in vitro (LIV) is 90 days. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 10 (in Chenopodium quinoa sap).

Nucleic Acid

The genome is not segmented and contains a single molecule of linear positive-sense, single-stranded RNA.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 2 structural protein(s).

Structural Proteins: Reference to method of preparation: Fribourg et al. (1987).

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to Cucumber green mottle mosaic, Frangipani mosaic, Odontoglossum ringspot, tobacco mosaic and ullucus viruses, but distantly. The virus does not show serological relationships to ribgrass mosaic and Sammons' opuntia viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is not transmitted by a vector. Virus is transmitted by mechanical inoculation; transmitted by contact between hosts.

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 Amaranthaceae, Chenopodiaceae, Compositae, Cucurbitaceae, Labiatae, Passifloraceae, Scrophulariaceae, Solanaceae. The following species were susceptible to experimental virus infection: Antirrhinum majus, Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Cucumis sativus, Cucurbita maxima, Cucurbita moschata, Datura stramonium, Gomphrena globosa, Helianthus annuus, Luffa acutangula, Lycopersicon chilense, Lycopersicon esculentum, Nicandra physalodes, Nicotiana benthamiana, Nicotiana glutinosa, Nicotiana tabacum, Passiflora edulis, Physalis floridana, Salvia splendens, Zinnia elegans.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Cruciferae, Cucurbitaceae, or Leguminosae-Papilionoideae, Pedaliaceae, Portulacaceae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Brassica campestris ssp. pekinensis, Cajanus cajan, Capsicum annuum, Capsicum frutescens, Citrullus vulgaris, Clitoria ternatea, Datura metel, Lycopersicon pimpinellifolium, Matthiola incana, Montia perfoliata, Phaseolus acutifolius, Phaseolus vulgaris, Sesamum indicum, Solanum tuberosum, Vigna unguiculata, Vigna unguiculata ssp. cylindrica.

Diagnostic Hosts

Diagnostic host species and symptoms:

Passiflora edulis — systemic leaf mosaic, crinkle.

Nicotiana benthamiana — necrotic local lesions; then systemic line patterns, mosaic.

Chenopodium quinoa, C. amaranticolor, Luffa acutangula — necrotic local lesions; not systemic.

Nicotiana tabacum — necrotic local lesions, necrotic rings and lines; not systemic.

Cucumis sativus, Nicotiana glutinosa — necrotic local lesions; not systemic.

Antirrhinum majus — symptomless local infection; not systemic.

Datura stramonium — chlorotic local lesions; not systemic.

Diagnostic host: insusceptible host species Brassica campestris ssp. pekinensis, Capsicum annuum, Citrullus vulgaris, Phaseolus vulgaris cv. Monroe, Vigna unguiculata.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Nicotiana benthamiana.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chenopodium quinoa (L).

References to host data: Fribourg et al. (1987).

Histopathology: Virus can be best detected in mesophyll, epidermis, vascular parenchyma and xylem. 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 crystals and amorphous X-bodies. Cytoplasmic inclusion bodies are associated with the tonoplast. Inclusions are tonoplast-associated small vesicles. Inclusions contain mature virions (in the crystals), or do not contain mature virions (in the others).

Geographical Distribution

The virus occurs in Peru.

Ecology, Epidemiology and Control

Studies reported by Fribourg et al. (1987).
