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: 00.077.0.01.018. Virus accession number: 77001018. Obsolete virus code: 77.0.1.0.014; superceded accession number: 77010014.

Name, Synonyms and Lineage

Synonym(s): Plantain mottle virus. ICTV approved acronym: PlMoV. Virus is an ICTV approved species. Virus is of the genus 00.077.0.01. Tymovirus; family 00.077. Tymoviridae.

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped, round with icosahedral symmetry. The isometric capsid has a diameter of 26.7 nm. The capsomer arrangement is clearly visible.

Electron microscopic preparation and references: Reference for electron microscopic methods: Granett (1973).

Physicochemical and Physical Properties

A260/A280 ratio is 8.51 (specific absorbance at 260 nm). The thermal inactivation point (TIP) is at 65°C. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 7-8.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, single-stranded RNA is recovered. The genome has a base ratio of 17 % guanine; 21 % adenine; 34 % cytosine; 28 % uracil.

Proteins

The viral genome encodes structural proteins and non-structural proteins.

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to Andean potato latent, dulcamara mottle, belladonna mottle, ononis yellow mosaic and turnip yellow 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 ROSIDAE.

General Symptoms in Plants Virus affects the photosynthetic system. Symptoms are expressed in the leaf include chlorosis and development of patterns or markings that are visible in the intercostal regions. Intercostal regions show chlorosis. Leaves with mottle.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

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

Experimental Hosts and Symptoms

Under experimental conditions susceptibility to infection by virus is found in several families. Susceptible host species are found in the Family Leguminosae-Papilionoideae, Martyniaceae, Plantaginaceae, Scrophulariaceae, Solanaceae, Tetragoniaceae. The following species were susceptible to experimental virus infection: Antirrhinum majus, Glycine max, Nicotiana clevelandii, Petunia x hybrida, Pisum sativum, Plantago major, Proboscidea jussieu, Tetragonia tetragonioides.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Apocynaceae, or Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, or Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Brassica campestris ssp. pekinensis, Brassica oleracea var. botrytis, Brassica oleracea var. capitata, Capsicum frutescens, Catharanthus roseus, Chenopodium amaranticolor, Chenopodium quinoa, Cucumis sativus, Cucurbita moschata, Cucurbita pepo, Datura stramonium, Gomphrena globosa, Lactuca sativa, Lupinus albus, Lycopersicon esculentum, Nicotiana sylvestris, Nicotiana tabacum, Phaseolus lunatus, Phaseolus vulgaris, Spinacia oleracea, Trifolium pratense, Trifolium repens, Vicia faba, Vigna unguiculata, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Glycine max, Pisum sativum — systemic mottle.

Proboscidea jussieu — necrotic local lesions, systemic mottle.

Plantago major — systemic mottle.

Antirrhinum majus — necrotic ringspots not systemic.

Nicotiana clevelandii — systemic mottle.

Petunia x hybrida, Tetragonia tetragonioides — systemic mottle.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Pisum sativum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Plantago major, Nicotiana clevelandii, Antirrhinum majus.

References to host data: Granett (1973).

Histopathology: Virus can be best detected in all parts of the host plant. Virions are found in the cytoplasm.

Geographical Distribution

The virus occurs in the United States of America (in New York State).
