Nomenclature

ICTV decimal code

57.0.1.DE.11

Host range and symptoms

Natural host range and symptoms

Symptoms persist and vary seasonally. Symptoms leaf mottling.
• Polianthes tuberosa - irregular foliar mottling.

Transmission

Spread in infected vegetative planting material. Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in New Zealand.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains many virions. Electron microscopy: negatively-stained virions from cut leaf edges, better than sap extracts.

Purification method

Horner and Pearson (1988).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 749 nm; 15 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations. A₂₆₀/A₂₈₀ ratio 1.038.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves, mesophyll and meristems; in cytoplasm. Inclusions present in infected cells; are unusual in shape; stacked plates (laminated aggregates) thought to be parts of cylindrical or pinwheel inclusions; they do not contain virions.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically unrelated virions

Tulip breaking virus.
