Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Hippeastrum hybridum, H. equestre, Eucharis grandiflora - chlorotic streaking of leaves and flower stalks.

Transmission

Transmitted by a vector; an insect; Aphis fabae, A. gossypii, Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Geographical distribution

Spreads in the former Czechoslovakia, Fiji, Japan, the Netherlands, South Africa, the UK, and the USA.

Experimental host range

Sources of host-range data

Brants and van den Heuvel (1965); Jayasinghe and Dijkstra (1979).

Physical and biochemical properties

Properties of particles in sap

TIP: 60 °C (in Hippeastrum hybridum sap). LIV: 2 days (in H. hybridum sap). DEP: log₁₀ minus 4. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains few virions.

Purification method

Brunt (1973); Jayasinghe and Dijkstra (1979).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 782 nm; 12 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 153 S. Density 1.31 g cm^-3 in CsCl (unfixed). A₂₆₀/A₂₈₀ ratio 1.21 (corrected for scattering).

Biochemical properties

Virions contain 4.5 % nucleic acid; 95.5 % protein; 0 % lipid.

Features of proteins

Virion protein(s) one; M_r 32000. Method of preparation: Brunt et al. (1975).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm (as membrane-associated aggregates). Inclusions present in infected cells; are pinwheels and unusual in shape; and bundles near the nucleus. Other cellular changes: chloroplasts being smaller in infected cells.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically unrelated virions

Bean yellow mosaic, carnation vein mottle, clover yellow vein, iris mild mosaic, lettuce mosaic, tobacco etch, potato Y and turnip mosaic viruses. Reported relationships with other potyviruses have not been confirmed (Brunt and Phillips, unpublished results).

Comments and References

General comments

Gomphrena globosa and Tetragonia tetragonioides have been reported as local lesion hosts of hippeastrum mosaic virus, but are not, however they are susceptible to hippeastrum latent virus, a carlavirus which is closely related to nerine latent and carnation latent viruses, and which frequently occurs, together with hippeastrum mosaic virus, in hippeastrums.
