Nomenclature

Acronym

PnCV

ICTV decimal code

49.0.3.T.006

Host range and symptoms

Natural host range and symptoms

• Euphorbia pulcherrima - no symptoms.

Ecology and control

Studies reported by Preil et al. (1982); Paludan et al. (1982).

Geographical distribution

Found, but with no evidence of spread, in Germany.

Susceptible host species

• Euphorbia pulcherrima

Families containing susceptible hosts

• Euphorbiaceae (1/1)

Physical and biochemical properties

Particle morphology

Virions isometric; not enveloped; 28 nm in diameter (may be of two sizes 26 nm and 31 nm diameter); rounded in profile; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 120 S.

Taxonomy and relationships

Possible Alphacryptovirus: Partitiviridae

Additional comments on relationships

As plants may be freed of virus by meristem or cell culture, it may not be a typical cryptovirus (Boccardo et al., 1987).
