Data collated by A.T. Jones, 1987. Checked 1989.

Nomenclature

Synonyms

probably raspberry yellow mosaic virus.

Acronym

RYNV

ICTV decimal code

07.0.1.T.DE.1

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Rubus strigosus (red raspberry) - chlorotic netting of leaf veins.
• R. procerus (Himalayan blackberry) - chlorotic netting or yellow chlorosis, or no symptoms.
• R. occidentalis (black raspberry) - chlorotic netting of leaf veins. N.B. the virus usually occurs mixed with other aphid-borne viruses, and these induce mosaic diseases of red and black raspberry.

Transmission

Transmitted by a vector; an insect; Aphididae. Transmitted in a semi-persistent manner. Virus lost by the vector when it moults; not transmitted congenitally to the progeny of the vector; not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by pollen.

Ecology and control

Studies reported by Stace-Smith and Jones (1978).

Geographical distribution

Spreads in the Eurasian region and the North American region.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Rubus idaeus, R. occidentalis, R. procerus - vein netting.
• Fragaria vesca - downcurling of leaves, then necrosis of petiole, wilting and plant death.
• Rubus macraei - vein netting.

Maintenance and propagation hosts

Rubus macraei, R. idaeus, R. occidentalis.

Susceptible host species

• Fragaria vesca
• Rubus idaeus
• Rubus macraei
• Rubus occidentalis
• Rubus procerus
• Rubus strigosus

Families containing susceptible hosts

• Rosaceae (6/6)

Sources of host-range data

Stace-Smith and Jones (1978); Jones and Badenoch (1982).

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions. Electron microscopy: 2% AM (pH 6.5).

Particle morphology

Virions bacilliform; not enveloped; 80-150 nm in length; 25-31 nm wide.

Replication

Replication does not depend on a helper virus.

Cytopathology

Virions found in leaves, mesophyll, epidermis and vascular parenchyma; in cytoplasm. Inclusions absent from infected cells. Other cellular changes: cell wall outgrowths and parallel arrangements of long tubules.

Taxonomy and relationships

Probably Badnavirus
