Host range and symptoms

Natural host range and symptoms

Symptoms persist and vary seasonally.
• Capsicum annuum - mottling and malformed leaves.
• Datura meteloides - mild mottle.
• Solanum sp. - systemic mild mottle.

Transmission

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

Ecology and control

Geographical distribution

Spreads in El Salvador, India, and the USA (Florida, New Mexico, Texas, Arizona and California).

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Capsicum annuum - severe systemic leaf mottling in all susceptible cultivars.
• Capsicum frutescens - necrotic local lesions; systemic leaf necrosis and death of young Tabasco plants.
• Datura meteloides, Lycopersicon esculentum - mild systemic mottling.
• Nicotiana glutinosa, N. tabacum, Physalis floridana - systemic leaf mottling.
• Chenopodium amaranticolor - necrotic local lesions; not systemic.

Features of proteins

Virion protein(s) two (Hiebert and McDonald, 1973).

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves and epidermis; in cytoplasm. Inclusions present in infected cells; are pinwheels and unusual in shape; with striated lamellae.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Potato Y, tobacco etch and pepper veinal mottle viruses, but distantly. Peptide analyses show that the virus has close affinities with potato Y virus (D. Shukla, unpublished information).

Virus(es) with serologically unrelated virions

Bidens mottle, lettuce mosaic and turnip mosaic viruses.

Best tests for diagnosis

See Nelson et al. (1982).
