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: 00.057.0.81.008. Virus accession number: 57081008. Obsolete virus code: 57.0.1.T.008; superceded accession number: 5701t008.
NCBI Taxon Identifier NCBI Taxonomy ID: 320856.

Name, Synonyms and Lineage

ICTV approved acronym: BiMV. Virus is an ICTV approved species 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 730 nm and a width of 15 nm. Axial canal is indistinct. Basic helix is obscure.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Marinho and Kitajima (1989).

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 55-60°C. The longevity in vitro (LIV) is 5 days. 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.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

Lipids

Lipids are not reported.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Magnoliopsida (Dicotyledonae).

General Symptoms in Plants Symptoms mosaics.

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; transmitted by grafting; not transmitted by seeds.

Vector Transmission:
Virus is transmitted by arthropods, by insects of the order Hemiptera, family Aphididae; Aphis coreopsidis, Myzus persicae, Dactynotus ssp. The principal natural vector(s) are Aphis coreopsidis. Virus is transmitted in a non-persistent manner.

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, Compositae, Leguminosae-Caesalpinioideae, Leguminosae-Papilionoideae, Solanaceae. The following species were susceptible to experimental virus infection: Acanthospermum hispidum, Bidens pilosa, Callistephus chinensis, Cassia occidentalis, Chenopodium amaranticolor, Chenopodium quinoa, Coreopsis lanceolata, Helianthus annuus, Lactuca sativa, Lupinus albus, Lupinus angustifolius, Nicotiana debneyi, Nicotiana glutinosa, Nicotiana rustica, Nicotiana tabacum, Physalis floridana, Pisum sativum, Solanum nigrum, Zinnia elegans.

Host:
Experimentally infected hosts mainly show symptoms of mosaics, local necrotic lesions, local and systemic chlorotic spots.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Amaranthaceae, Chenopodiaceae, Compositae, Cruciferae, Cucurbitaceae, Euphorbiaceae, Gramineae, or Leguminosae-Papilionoideae, Scrophulariaceae, Solanaceae (3 /9), or Tetragoniaceae, Umbelliferae. Species inoculated with virus that do not show signs of susceptibility: Ageratum conyzoides, Antirrhinum majus, Arachis hypogaea, Brassica oleracea var. capitata, Capsicum annuum, Chenopodium capitatum, Chenopodium murale, Citrullus lanatus, Coriandrum sativum, Cucumis melo, Cucurbita maxima, Datura stramonium, Euphorbia heterophylla, Galinsoga parviflora, Glycine max, Gomphrena globosa, Hordeum vulgare, Lycopersicon esculentum, Medicago sativa, Phaseolus vulgaris, Raphanus sativus, Tetragonia tetragonioides, Trifolium pratense, Trifolium repens, Triticum aestivum.

Diagnostic Hosts

Diagnostic host species and symptoms:

Nicotiana tabacum cv. White Burley — chlorotic local and systemic spotting.

Zinnia elegans — systemic mosaic.

Lactuca sativa, Pisum sativum — mosaic.

Helianthus annuus — systemic chlorotic and necrotic spotting, mosaics.

Callistephus chinensis — systemic vein clearing and mosaic.

Acanthospermum hispidum — systemic chlorotic spots.

Bidens pilosa — mosaic and vein banding.

Chenopodium amaranticolor — necrotic local lesions.

C. quinoa — chlorotic local lesions.

Diagnostic host: insusceptible host species Phaseolus vulgaris, Cucurbita maxima, Euphorbia heterophylla, Triticum aestivum, Gomphrena globosa.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Lactuca sativa, Bidens pilosa, Helianthus annuus.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chenopodium quinoa (L), C. amaranticolor (L), Lactuca sativa (W), Helianthus annuus (W).

References to host data: Kuhn et al. (1980).

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. Cytoplasmic inclusions are pinwheels. Other cellular changes include Kuhn et al. (1982).

Geographical Distribution

The virus occurs in Brazil.
