Isolate Description

Location: Andra Pradesh; India.

Host of Isolate and Habitat Details
Source of isolate: Cicer arietinum.

Natural host and symptoms
Cicer arietinum — small chlorotic brittle leaves, axillary buds activated but stunted giving bushy dwarf symptoms.

Reference to Isolation Report
Anjaiah et al. (1989).

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: 00.057.0.81.017. Virus accession number: 57081017. Obsolete virus code: 57.0.1.T.017; superceded accession number: 5701t017.

Name, Synonyms and Lineage

ICTV approved acronym: CpBDV. 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 700-720 nm and a width of 13-15 nm. Axial canal is indistinct.

Electron microscopic preparation and references: Virus preparation contains few virions. Reference for electron microscopic methods: Anjaiah et al. (1989).

Physicochemical and Physical Properties

There are 1 sedimenting component(s) found in purified preparations.

Nucleic Acid

The genome is monopartite. Only one particle size of linear, positive-sense, single-stranded RNA is recovered. The complete genome is 10000 nucleotides long. Genome is sequenced, but only an estimate is available, complete sequence is 10000 nucleotides long. Reference to nucleotide sequence Anjaiah et al. (1989).

Proteins

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

Structural Proteins: Reference to method of preparation: Anjaiah et al. (1989).

Lipids

Lipids are not reported.

Antigenicity

The virus is serologically related to azuki bean mosaic, peanut mottle and soybean mosaic virus; peanut stripe and blackeye cowpea mosaic are more distantly related. The virus does not show serological relationships to bean yellow mosaic virus.

Diagnostics and Reference Collections

The best tests for diagnosis are In India, chickpea may be also infected with alfalfa mosaic, bean yellow mosaic, cucumber mosaic and chickpea stunt viruses. In the U.S.A., chickpea filiform virus (Kaiser et al., 1988) also infects chickpea, and bean yellow mosaic and beet western yellow virus are found in chickpea in other parts of the world. Serological and host range tests distinguishes readily between these 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).

Severity and Occurrence of Disease

Host: Signs and symptoms persist.

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-Caesalpinioideae, Leguminosae-Papilionoideae, Malvaceae, Solanaceae. The following species were susceptible to experimental virus infection: Canavalia ensiformis, Cassia obtusifolia, Chenopodium amaranticolor, Chenopodium murale, Chenopodium quinoa, Cicer arietinum, Cyamopsis tetragonoloba, Gossypium herbaceum, Macrotyloma uniflorum, Nicotiana benthamiana, Phaseolus lunatus, Phaseolus vulgaris (cvs Bountiful, Pinto).

Host:
Experimentally infected hosts mainly show symptoms of mosaics, mottles, ringspots or necrosis.

Experimentally infected insusceptible Hosts: Families containing insusceptible hosts: Cucurbitaceae, Leguminosae-Papilionoideae, or Solanaceae. Species inoculated with virus that do not show signs of susceptibility: Arachis hypogaea, Cucumis sativus, Glycine max, Nicotiana clevelandii, Nicotiana glutinosa, Nicotiana rustica, Petunia x hybrida, Phaseolus lunatus, Phaseolus vulgaris (cv. Top Crop), Pisum sativum, Vigna radiata, Vigna unguiculata.

Diagnostic Hosts

Diagnostic host species and symptoms:

Cicer arietinum — chlorotic bushy dwarf.

Chenopodium amaranticolor, C. murale, Cyamopsis tetragonoloba — chlorotic local lesions; not systemic.

Canavalia ensiformis, Chenopodium quinoa, Gossypium herbaceum, Nicotiana benthamiana, Phaseolus vulgaris cvs Bountiful, Pinto — systemic necrosis.

Macrotyloma uniflorum, Cassia obtusifolia — necrotic local lesions; not systemic.

Diagnostic host: insusceptible host species Arachis hypogaea, Cucumis sativus, Nicotiana glutinosa, Pisum sativum cv. Bonneville, Phaseolus vulgaris cv. Top Crop.

Maintenance and Propagation Hosts

Most commonly used maintenance and propagation host species are Cicer arietinum.

Assay Hosts

Host: Assay hosts (for Local lesions or Whole plants):
Chenopodium amaranticolor (L).

References to host data: Anjaiah et al. (1989).
