Classification

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

ICTVdB Virus Code: 00.056.0.81.011. Virus accession number: 56081011. Obsolete virus code: 56.0.1.T.011; superceded accession number: 5601t011.
NCBI Taxon Identifier NCBI Taxonomy ID: 315713.

Name, Synonyms and Lineage

Synonym(s): nandina (?) virus. ICTV approved acronym: NaMV. Virus is a tentative member. Virus is of the genus 00.056.0.01. Potexvirus in the family 00.056. Flexiviridae.

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 length of 471 nm. Axial canal is indistinct. Basic helix is obscure.

Electron microscopic preparation and references: Reference for electron microscopic methods: Zettler et al. (1980).

Physicochemical and Physical Properties

A260/A280 ratio is 1.35.

Nucleic Acid

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

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

The viral genome encodes structural proteins and non-structural proteins. Virions consist of 1 structural protein(s).

Lipids

Lipids are not reported.

Transcription: The virus codes for 5 ORF(s).

Coding Strategy of Segment 1: Sequence has a gene block. Sequence has triple gene block sequence (TGB). Encodes proteins involved in cell to cell movement.

Antigenicity

The virus does not show serological relationships to clover yellow mosaic, Cymbidium mosaic, hydrangea ringspot, papaya mosaic, potato X and white clover 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 MAGNOLIIDAE;
Family Nandinaceae (~Berberidaceae). Virus found in Nandina domestica (heavenly bamboo) [TaxID 41776].

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is transmitted by mechanical inoculation.

Vector Transmission: Virus is not transmitted by Myzus persicae.

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 Amaranthaceae, Apocynaceae, Chenopodiaceae, Leguminosae-Caesalpinioideae, Nandinaceae, Solanaceae. The following species were susceptible to experimental virus infection: Cassia occidentalis, Catharanthus roseus, Chenopodium amaranticolor, Chenopodium quinoa, Gomphrena globosa, Nandina domestica, Nicotiana benthamiana, Nicotiana megalosiphon, Spinacia oleracea.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Caricaceae, Chenopodiaceae, Compositae, or Cruciferae, Cucurbitaceae, Gramineae, Leguminosae-Papilionoideae, or Scrophulariaceae, Solanaceae, Tetragoniaceae, Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Antirrhinum majus, Beta vulgaris, Brassica oleracea var. capitata, Capsicum annuum, Carica papaya, Crotalaria spectabilis, Cucumis sativus, Dahlia pinnata, Datura stramonium, Glycine max, Gynura aurantiaca, Hordeum vulgare, Lactuca sativa, Lathyrus odoratus, Lycopersicon esculentum, Melilotus albus, Nicotiana glutinosa, Nicotiana rustica, Nicotiana tabacum, Nicotiana x edwardsonii, Pastinaca sativa, Phaseolus vulgaris, Physalis floridana, Pisum sativum, Solanum melongena, Tetragonia tetragonioides, Trifolium pratense, Trifolium repens, Vigna unguiculata, Zinnia elegans.

Diagnostic Hosts

Diagnostic host species and symptoms:

Gomphrena globosa, Chenopodium amaranticolor, Cassia occidentalis — local lesions; not systemic.

Nicotiana benthamiana, N. megalosiphon — systemic mottling and malformation.

Chenopodium quinoa, Spinacia oleracea — local lesions; then systemic chlorosis. Diagnostic host: insusceptible host species Cucumis sativus, Datura stramonium, Nicotiana glutinosa, N. tabacum, Phaseolus vulgaris.

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):
Gomphrena globosa (L).

Histopathology: Virus can be best detected in leaves, mesophyll and the epidermis. Virions are found in the cytoplasm.

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm. Inclusions are aggregated virions. Inclusions contain mature virions.

Geographical Distribution

The virus occurs in the United States of America (in California).
