Classification

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

ICTVdB Virus Code: 00.057.0.81.055. Virus accession number: 57081055. Obsolete virus code: 57.0.1.T.055; superceded accession number: 5701t055.

Name, Synonyms and Lineage

ICTV approved acronym: MMTV. Virus has not been assigned to a particular genus. Virus is 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, flexuous with a clear modal length with a length of 750 nm and a width of 13 nm. Axial canal is indistinct.

Electron microscopic preparation and references: Reference for electron microscopic methods: Sun et al. (1977).

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 common mosaic, bean yellow mosaic, henbane mosaic, peanut mottle, potato Y, soybean mosaic and tobacco etch viruses.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms).

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation.

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 Chenopodiaceae, Leguminosae-Papilionoideae, Solanaceae. The following species were susceptible to experimental virus infection: Chenopodium amaranticolor, Chenopodium quinoa, Nicotiana glutinosa, Phaseolus acutifolius, Phaseolus vulgaris, Vigna radiata, Vigna unguiculata ssp. sesquipedalis .

Diagnostic Hosts

Diagnostic host species and symptoms:

Chenopodium amaranticolor, C. quinoa — local lesions.

Nicotiana glutinosa, Phaseolus acutifolius, P. vulgaris, Vigna radiata, V. unguiculata ssp. sesquipedalis — systemic leaf chlorosis and deformation.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Vigna radiata, V. unguiculata ssp. sesquipedalis.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Vigna radiata (W), Vigna unguiculata ssp. sesquipedalis (W).

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Cytoplasmic inclusions are pinwheels. Inclusions do not contain mature virions.

Geographical Distribution

The virus occurs in Taiwan.
