Isolate Description

Location: Puerto Rico.

Host of Isolate and Habitat Details
Source of isolate: Canavalia maritima.

Classification

This is a description of a plant virus at the species level.

ICTVdB Virus Code: 00.057.0.81.013. Virus accession number: 57081013. Obsolete virus code: 57.0.1.T.013; superceded accession number: 5701t013.

Name, Synonyms and Lineage

ICTV approved acronym: CnMMV. Virus is a tentative member of the genus 00.057.0.01. Potyvirus; family 00.057. Potyviridae .

Virion Properties

Morphology

Virions consist of a capsid. Virus capsid is not enveloped. Capsid/nucleocapsid is elongated with helical symmetry. The capsid is filamentous.

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

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 55-60°C. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 3.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered.

Proteins

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

Lipids

Lipids are not reported.

Antigenicity

The virus does not show serological relationships to bean yellow mosaic and bean common 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).

Transmission and Vector Relationships

Virus is transmitted by a vector. Virus is transmitted by mechanical inoculation.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Aphis craccivora, A gossypii, Myzus persicae. Virus is not transmitted by Dactynotus ambrosiae.

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 Chenopodiaceae, Leguminosae-Papilionoideae. The following species were susceptible to experimental virus infection: Canavalia maritima, Chenopodium album, Chenopodium amaranticolor, Chenopodium quinoa, Glycine max, Phaseolus lunatus, Phaseolus vulgaris, Spinacia oleracea, Vicia faba, Vigna angularis, Vigna radiata, Vigna unguiculata.

Host:
Experimentally infected hosts mainly show symptoms of mosaic.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Cucurbitaceae, or Leguminosae-Caesalpinioideae, Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Capsicum annuum, Cassia occidentalis, Cucumis sativus, Datura stramonium, Gomphrena globosa, Medicago sativa, Nicotiana glutinosa, Nicotiana tabacum, Phaseolus vulgaris, Pisum sativum, Trifolium pratense, Trifolium repens, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Canavalia maritima — systemic mosaic, mottling and leaf malformation.

Phaseolus vulgaris cvs Bountiful, Top Crop, Vigna unguiculata cv. Early Ramshorn. Diagnostic host: insusceptible host species Phaseolus vulgaris cv. Green Refugee, Vigna unguiculata cv. Blackeye.

References to host data: Rodriguez et al. (1975).

Histopathology: Virus can be best detected in all parts of the host plant. 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 pinwheels.

Geographical Distribution

The virus occurs in Puerto Rico.
