Host range and symptoms

Natural host range and symptoms

• Vicia faba - yellow vein-banding, mottling; symptoms enhanced when co-infecting with pea enation mosaic enamovirus.

Transmission

Transmitted by a vector; an insect; Acyrthosiphon pisum, Myzus persicae; Aphididae. Not transmitted by Aphis fabae. Transmitted in a persistent manner. Virus requires, for vector transmission, a helper virus (pea enation mosaic enamovirus in the field; or bean leaf roll luteovirus in glasshouse tests); transmitted by mechanical inoculation.

Geographical distribution

Spreads in the UK.

Experimental host range

Many (>9) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor, C. quinoa - local chlorotic or necrotic lesions; no symptoms.
• Nicotiana clevelandii, N. glutinosa, Pisum sativum, Trifolium incarnatum, Vicia faba, V. sativa - no local symptoms; systemic mottling.

Susceptible host species

• Chenopodium amaranticolor
• Chenopodium quinoa
• Nicotiana clevelandii
