Nomenclature

ICTV decimal code

79.0.P.DE.17

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Dodonaea viscosa - pendulous `witches brooms' formed of abnormally long proliferated branches, the leaves on which are small and chlorotic.

Transmission

Virus not transmitted by mechanical inoculation.

Geographical distribution

Spreads in the USA (Hawaii).

Susceptible host species

• Dodonaea viscosa

Families containing susceptible hosts

• Sapindaceae (1/1)

Purification method

Borth et al. (1990).

Physical and biochemical properties

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 700 nm; 16 nm wide.

Features of the genome

1 virus specified dsRNA species found in infected cells. Size of largest virus specified dsRNA 3 kbp.

Taxonomy and relationships

(ungrouped)

Comments and References

General comments

The symptoms in Dodonaea viscosa resemble those induced by mycoplasma-like organisms (MLO) in other hosts. Although no MLO were detected in affected plants, further work is necessary to elucidate the etiology of the disease.
