GVA

ICTV decimal code

76.0.1.T.003

Host range and symptoms

Natural host range and symptoms

Vitis vinifera - leaf rolling, reddening of leaf margins and petioles, and localised swelling and cracking of stems (probably Kober stem grooving disease).

Transmission

Transmitted by a vector; an insect; Pseudococcus longispinus, Planococcus citri, P. ficus; Pseudococcidae. Virus transmitted by mechanical inoculation.

Geographical distribution

Found, but with no evidence of spread, in France, Italy, Israel, Switzerland, South Africa, Tunisia and Yemen.

Diagnostically susceptible host species and symptoms

• Nicotiana benthamiana, N. clevelandii - narrow leaflets, vein-banding of systemically infected leaves, followed by mottling and puckering.
• Vitis vinifera - leaf rolling and reddening (in autumn).

Diagnostically insusceptible host species

Chenopodium amaranticolor, C. quinoa, Cucurbita pepo, Cucumis sativus, Nicotiana glutinosa, N. rustica, N. tabacum, N. rustica, Phaseolus vulgaris, Pisum sativum.
