Nomenclature

Synonyms

Tongan vanilla virus.

Acronym

VanMV

ICTV decimal code

57.0.1.T.091

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Vanilla tahitensis, Vanilla pompona - leaf mosaic and malformation.

Transmission

Transmitted by a vector; an insect; Myzus persicae; Aphididae. Transmitted in a non-persistent manner.

Geographical distribution

Found, but with no evidence of spread, in French Polynesia on the islands of Huahine, Raiatea, Tahaa and Tahiti.

Diagnostically susceptible host species and symptoms

• Vanilla pompona - no symptoms in leaves inoculated by aphids but then systemic terminal necrosis and mosaic and malformation.

Susceptible host species

• Vanilla pompona
• Vanilla tahitensis

Families containing susceptible hosts

• Orchidaceae (2/2)

Physical and biochemical properties

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 767 nm. Axial canal obscure. Basic helix obscure.

Cytopathology

Virions found in mesophyll; in cytoplasm. Inclusions present in infected cells; are pinwheels and unusual in shape; scrolls and laminated aggregates.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Bidens mottle and tobacco etch viruses are serologically related to, but distinct from, vanilla mosaic potyvirus in SDS immunodiffusion tests. In tests with dasheen mosaic virus, and its homologous antiserum, bands of precipitate formed that were fully confluent with those of the vanilla potyvirus.
