Nomenclature

Acronym

GCBaV

ICTV decimal code

17.0.1.T.U.03

Host range and symptoms

Natural host range and symptoms

Vitis vinifera - in intolerant cultivars, delayed bud opening, reduced vigour and yield, swelling of trunk and, sometimes, thick and rough spongy bark; woody cylinder of rootstock and/or scion pitted and/or grooved. Some cultivars and rootstocks are tolerant and produce no symptoms.

Transmission

Transmitted by a vector; an insect; Psyllidae. Not transmitted by Planococcus ficus. Virus not transmitted by mechanical inoculation; transmitted by grafting.

Geographical distribution

Spreads in the African region.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Vitis berlandieri × Conderc 1613 (LN33) - swelling of basal internodes due to proliferation of secondary phloem, and stem grooving.
• Vitis berlandieri × V. riparia (Kober SBB) - symptomless.
• Vitis rupestris - stem grooving.

Maintenance and propagation hosts

Vitis vinifera (LN33) and V. rupestris.

Susceptible host species

• Vitis berlandieri × Conderc 1613
• Vitis berlandieri × V. riparia
• Vitis rupestris
• Vitis vinifera

Families containing susceptible hosts

• Vitidaceae (4/4)

Physical and biochemical properties

Particle morphology

Virions filamentous; usually flexuous; of 1400-2000 nm.

Taxonomy and relationships

Possible Closterovirus
