ICTV decimal code

57.0.1.T.058

Host range and symptoms

Natural host range and symptoms

Symptoms persist.
• Tropaeolum majus - vein clearing, mottling and slight leaf malformation; occasionally flower breaking.

Transmission

Transmitted by a vector; an insect; Aphis fabae, Dysaphis apifolia, Myzus persicae, Aulocorthum circumflexum, Rhopalosiphum padi; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in Brazil, South Africa, the UK, and the USA.

Experimental host range

Few (<3) families susceptible.

Diagnostically susceptible host species and symptoms

• Tropaeolum majus - severe leaf mosaic.
• Zinnia elegans - mild leaf chlorosis.

Maintenance and propagation hosts

Tropaeolum majus, Zinnia elegans.

Assay hosts (Local lesions or Whole plants)

Tropaeolum majus (W).

Susceptible host species

• Tropaeolum majus
• Zinnia elegans

Families containing susceptible hosts

• Compositae (1/1)
• Tropaeolaceae (1/1)

Physical and biochemical properties

Properties of particles in sap

TIP: 60 °C. LIV: 2-4 days.

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 750 nm.

Taxonomy and relationships

Possible Potyvirus: Potyviridae

Additional comments on relationships

Although there is no definite evidence, it is thought that the viruses in Tropaeolum majus in Brazil, South Africa, the U.K. and the U.S.A. are the same (da Graca and Martin, 1977).
