Isolate Description

Location: the United States of America (and the U.K).

Host of Isolate and Habitat Details
Source of isolate: Tropaeolum majus.

Natural host and symptoms

Classification

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

ICTVdB Virus Code: 00.057.0.81.058. Virus accession number: 57081058. Obsolete virus code: 57.0.1.T.058; superceded accession number: 5701t058.

Name, Synonyms and Lineage

The taxon is not listed in the current ICTV Report.

ICTV approved acronym: NasMV. Virus is a tentative member. Virus is of the genus 00.057.0.01. Potyvirus in the 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, flexuous with a clear modal length with a length of 750 nm.

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 60°C. The longevity in vitro (LIV) is 2-4 days.

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

Although there is no definite evidence, it is thought that the viruses in Tropaeolum majus in Brazil, South Africa, the U.K. and the U.S.A. are the same (da Graca and Martin, 1977).

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 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 fabae, Dysaphis apifolia, Myzus persicae, Aulocorthum circumflexum, Rhopalosiphum padi. Virus is transmitted in a non-persistent manner.

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 Compositae, Tropaeolaceae. The following species were susceptible to experimental virus infection: Tropaeolum majus, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Tropaeolum majus — severe leaf mosaic.

Zinnia elegans — mild leaf chlorosis.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Tropaeolum majus, Zinnia elegans.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Tropaeolum majus (W).

Geographical Distribution

The virus occurs in Brazil, South Africa, the United Kingdom, and the United States of America.
