Nomenclature

Synonyms

tomato bushy stunt virus - petunia strain (Martelli et al., 1971).

Acronym

PeAMV (PAMV)

ICTV decimal code

74.0.1.0.012

Host range and symptoms

Natural host range and symptoms

• Petunia × hybrida - yellow stellate spots in leaves, leaf distortion and flower colour breaking.
• Humulus lupulus - yellow mottling and leaf distortion.
• Ligustrum vulgare, Cornus sanguinea - chlorotic leaf spotting.
• Prunus avium - leaf veinal necrosis and distortion, leaves bunched, shoots stunted with bark splitting, fruits with sunken pits.
• Prunus domestica - pox-like markings on fruits.
• Spinacia oleracea - Vein clearing, leaf mottling and distortion and stunting.
• Vitis vinifera - symptoms unknown as the virus only found in mixtures with others.

Transmission

Transmitted by means not involving a vector; probably abiotically in soil. Virus transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in the Eurasian region; Canada, the former Czechoslovakia, Germany, Switzerland, the UK, and the former Yugoslavia.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show local lesions or necrotic lesions.

Susceptible host species

• Cornus sanguinea
• Humulus lupulus
