Data collated by T. Inouye, 1981. Revised 1989.

Nomenclature

ICTV decimal code

79.0.P.DE.34

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Glycine max - chlorotic spots, mild mottling.

Transmission

Transmitted by a vector; an insect; Myzus persicae; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation; transmitted by seed (22-70% in Glycine max cultivars).

Geographical distribution

Spreads in Japan.

Experimental host range

Several (3-9) families susceptible.

Diagnostically susceptible host species and symptoms

• Chenopodium amaranticolor - chlorotic local lesions; systemic mosaic.
• Spinacia oleracea - necrotic and chlorotic local lesions; systemic chlorotic spotting and vein-clearing.
• Cucumis sativus - chlorotic local lesions or latent.
• Glycine max, Pisum sativum - systemic mosaic.
• Vigna radiata, V. unguiculata - necrotic local lesions; systemic vein-clearing and necrotic spotting.
• Nicotiana glutinosa, N. tabacum - systemic mosaic.

Diagnostically insusceptible host species
