Nomenclature

Acronym

CdMV.

ICTV decimal code

57.0.1.0.012

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Elettaria cardamomum - mosaic, possibly the same as the `Katte' or marble disease described in India.

Transmission

Transmitted by a vector; an insect; Pentalonia nigronervosa; Aphididae. Transmitted in a non-persistent manner. Virus not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed.

Geographical distribution

Spreads in Guatemala and India (possibly).

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show mosaic.

Diagnostically susceptible host species and symptoms

• Elettaria cardamomum - systemic mosaic.

Maintenance and propagation hosts

Elettaria cardamomum.

Susceptible host species

• Elettaria cardamomum

Families containing susceptible hosts

• Zingiberaceae (1/1)

Purification method

Gonsalves et al. (1986).

Physical and biochemical properties

Particle morphology

Virions filamentous; not enveloped; usually flexuous; of 700-720 nm. Basic helix obscure.

Biochemical properties

Genome consists of RNA; single-stranded; linear; unipartite.

Features of proteins

M_r 37500 (also fragments of 32200 and 29000); capsid. Method of preparation: Gonsalves et al. (1986).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm. Inclusions present in infected cells; are pinwheels.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Zucchini yellow mosaic, papaya ringspot and several legume potyviruses.
