Nomenclature

ICTV decimal code

79.0.P.DE.18

Host range and symptoms

Natural host range and symptoms

Symptoms vary seasonally. Symptoms leaf rolling and stunting in spring.
• Vitis vinifera, V. thunbergii - leaf rolling and stunting.

Transmission

Transmitted by a vector and means not involving a vector; an insect; Arboridia apicalis; Cicadellidae. Not transmitted by Myzus persicae. Transmitted in a persistent manner. Virus not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed.

Ecology and control

Studies reported by Yamashita: control by vector insect control and use of virus-free stock for grafting.

Geographical distribution

Spreads in Japan.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show leaf rolling and stunting.

Diagnostically susceptible host species and symptoms

• Vitis vinifera cv. Campbell Early, V. thunbergii - leaf rolling and stunting.

Maintenance and propagation hosts

Vitis vinifera cv. Campbell Early.

Susceptible host species

• Vitis thunbergii
• Vitis vinifera

Insusceptible host species

• Brassica oleracea var. botrytis
• Brassica oleracea var. capitata
• Chenopodium amaranticolor
• Chenopodium quinoa
• Cucumis sativus
• Datura stramonium
• Glycine max
• Gomphrena globosa
• Lycopersicon esculentum
• Nicotiana glutinosa
• Nicotiana rustica
• Nicotiana tabacum
• Petunia × hybrida
• Phaseolus vulgaris
• Physalis floridana
• Raphanus sativus
• Solanum melongena
• Tetragonia tetragonioides
• Vigna unguiculata

Families containing susceptible hosts

Families containing insusceptible hosts

• Amaranthaceae (1/1)
• Chenopodiaceae (2/2)
• Cruciferae (3/3)
• Cucurbitaceae (1/1)
• Leguminosae-Papilionoideae (3/3)
• Solanaceae (8/8)

Sources of host-range data

Hatamoto et al. (1982).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Namba et al. (1981 and 1986).

Particle morphology

Virions isometric; not enveloped; 25 nm in diameter; angular in profile; without a conspicuous capsomere arrangement.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves and phloem; in cytoplasm. Inclusions present in infected cells; are unusual in shape; are small vesicles containing fibrous material in the cytoplasm and vacuole. Other cellular changes: phloem necrosis, development of small vesicles and the accumulation of starch grains in chloroplasts in the mesophyll cells.

Taxonomy and relationships

(ungrouped)

Best tests for diagnosis

Induction of characteristic symptoms in Vitis vinifera cv. Campbell Early and Vitis thunbergii and leafhopper transmission.
