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: 00.056.0.01.022. Virus accession number: 56001022. Obsolete virus code: 00.056.0.81.002.; 56.0.1.T.002; superceded accession number: 56081002; 5601t002.
NCBI Taxon Identifier NCBI Taxonomy ID: 35286.

Name, Synonyms and Lineage

ICTV approved acronym: BaMV. Virus is an ICTV approved species 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 with a length of 490 nm and a width of 15 nm. Axial canal is indistinct.

Electron microscopic preparation and references: Virus preparation contains many virions. Reference for electron microscopic methods: Lin et al. (1977).

Physicochemical and Physical Properties

The thermal inactivation point (TIP) is at 65-70°C. Although the titer is dependent on the host, the decimal exponent (DEX) of the dilution end point is usually around 5-6.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered, is fully sequenced, complete sequence is 6366 nucleotides long and encodes capsid protein; movement protein; polymerase. Sequence has the accession number
[D26017] Em(43)_vi:Am1bamvgr Gb(89)_vi:Am1bamvgr bamboo mosaic virus BaMV gRNA gene. 10/94 6,366bp.

GenBank records for nucleotide sequences; complete genome sequences.

Proteins

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

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.

Biological Properties

Natural Host

Domain
Viral hosts belong to the Domain Eucarya.

Domain Eucarya
Kingdom Plantae.

Kingdom Plantae
Phylum Magnoliophyta (Angiosperms, Class Liliopsida (Monocotyledonae).

Class Liliopsida (Monocotyledonae)
Subclass COMMELINIDAE; Order Poales;
Family Poaceae. Virus found in Bambusa multiplex, Bambusa vulgaris.

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

Transmission and Vector Relationships

Virus is not transmitted by a vector. 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 Amaranthaceae, Chenopodiaceae, Gramineae. The following species were susceptible to experimental virus infection: Bambusa beecheyana, Bambusa edulis, Bambusa multiplex, Bambusa oldhamii, Bambusa vulgaris, Chenopodium amaranticolor, Dendrocalamus latiflorus, Gomphrena globosa, Phyllostachys nigra.

Host:
Experimentally infected hosts mainly show symptoms of mosaics, stunting.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Chenopodiaceae, Compositae, Cruciferae, or Gramineae, Leguminosae-Papilionoideae, Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Brassica oleracea var. botrytis, Capsicum annuum, Capsicum frutescens, Chenopodium quinoa, Datura metel, Datura stramonium, Lactuca sativa, Lycopersicon esculentum, Nicotiana glutinosa, Nicotiana tabacum, Oryza sativa, Phaseolus vulgaris, Raphanus sativus, Vigna unguiculata, Zea mays.

Diagnostic Hosts

Diagnostic host species and symptoms:

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

Bambusa vulgaris cv. Vittatu, Dendrocalamus latiflorus cv. Mei-nung — systemic mosaic.

Diagnostic host: insusceptible host species Phaseolus vulgaris, Capsicum annuum, Lycopersicon esculentum, Nicotiana tabacum cv. Turkish, Oryza sativa.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Bambusa multiplex, B. vulgaris, Dendrocalamus latiflorus.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Gomphrena globosa (L), Chenopodium amaranticolor (L), Bambusa vulgaris cv. Vittatu (W), Dendrocalamus latiflorus cv. Mei-nung (W).

References to host data: Lin et al. (1977; 1979).

Histopathology: Virus can be best detected in all parts of the host plant. Virions are found in the cytoplasm (in abundance), or cell vacuole and chloroplast (to which they are attached).

Cytopathology: Inclusions are present in infected cells. Inclusion bodies in the host cell are found in the cytoplasm, or nucleus. Nuclear inclusion bodies are crystals. Cytoplasmic inclusions are crystals. Inclusions do not contain mature virions.

Geographical Distribution

The virus spreads in Australasia and Pacific Islands. The virus occurs in the Philippines and Taiwan. The virus is found, but with no evidence of proliferation, in Brazil.
