Nomenclature

Acronym

CpBDV

ICTV decimal code

57.0.1.T.017

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Cicer arietinum - small chlorotic brittle leaves, axillary buds activated but stunted giving bushy dwarf symptoms.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show mosaics, mottles, ringspots or necrosis.

Diagnostically susceptible 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.

Diagnostically insusceptible host species

Arachis hypogaea, Cucumis sativus, Nicotiana glutinosa, Pisum sativum cv. Bonneville, Phaseolus vulgaris cv. Top Crop.

Maintenance and propagation hosts

Cicer arietinum.

Assay hosts (Local lesions or Whole plants)

Sources of host-range data

Anjaiah et al. (1989).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Anjaiah et al. (1989).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 700-720 nm; 13-15 nm wide. Axial canal obscure.

Physical properties

One sedimenting component in purified preparations.

Biochemical properties

Genome consists of RNA; single-stranded; linear. Total genome size 10 kb. Genome unipartite; largest (or only) genome part 10 kb. Genomic nucleic acid isolated by Anjaiah et al. (1989).

Features of proteins

Virion protein(s) one; M_r 32500 (, sometimes degraded to 29000); virion coat protein. Method of preparation: Anjaiah et al. (1989).

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Azuki bean mosaic, peanut mottle and soybean mosaic virus; peanut stripe and blackeye cowpea mosaic are more distantly related.

Virus(es) with serologically unrelated virions

Bean yellow mosaic virus.

Best tests for diagnosis

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 potyvirus (Kaiser et al., 1988) also infects chickpea, and bean yellow mosaic and beet western yellow luteovirus are found in chickpea in other parts of the world. Serological and host range tests distinguishes readily between these viruses.
