Nomenclature

Acronym

GLRaV-1, GLRaV-2, GLRaV-3, GLRaV-4, GLRaV-5

ICTV decimal code

17.0.1.T.U.04

Natural host range and symptoms

• Five viruses, designated grapevine leafroll-associated 1,2,3,4 and 5 closteroviruses have been associated with grapevine leafroll disease (Candresse and Martelli, 1995), but none has been fully characterized.
• Vitis vinifera - rolling and discoloration of leaves (reddish-purple in red-fruited, and yellowish in white-fruited cultivars), especially conspicuous in mate summer and early autumn in intolerant cultivars. Symptomless infection in some American Vitis spp. and hybrids.

Transmission

Transmitted by Pseudococcus longispinus, Planococcus ficus (GLRaV-3). Virus transmitted by grafting.

Geographical distribution

Probably distributed worldwide.

Diagnostically susceptible host species and symptoms

Vitis vinifera cvs Cabernet, Pinot Noir, Mission, Gamay - leafrolling and discoloration.

Susceptible host species

• Vitis vinifera

Families containing susceptible hosts

• Vitidaceae (1/1)

Physical and biochemical properties

Particle morphology

Virions filamentous; usually flexuous; of 1800-2200 nm.
