Nomenclature

Acronym

NSPV

ICTV decimal code

13.0.1.T.004

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Nandina domestica - mosaic, leaf cupping and malformation; stem pitting and grooving.

Transmission

Not transmitted by Myzus persicae. Virus not transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Found, but with no evidence of spread, in the U.S.A.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Nandina domestica - reddening and some inward curling of leaves.

Maintenance and propagation hosts

Nandina domestica.

Assay hosts (Local lesions or Whole plants)

Nandina domestica (W).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Ahmed et al. (1982); Lee et al. (1987).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 755 nm (or 1600-1800nm; Lee et al., 1987). Axial canal obscure. Basic helix obvious; pitch of basic helix 3.9 nm.

Physical properties

A₂₆₀/A₂₈₀ ratio 1.22-1.24.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves, meristems and phloem; in nuclei. Inclusions present in infected cells; are amorphous X-bodies; they contain virions.

Taxonomy and relationships

Possible Capillovirus
