57.0.1.0.071

Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms pale green blotches or streaks in leaves. Colour break symptoms in flowers.
• Tulipa spp. - blotching or streaking of leaves. Flower break symptoms indistinguishable from those caused by tulip breaking virus.

Transmission

Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in Australia.

Experimental host range

Several (3-9) families susceptible. Experimentally infected plants mostly show systemic chlorotic mottle and chlorotic local lesions.

Diagnostically susceptible host species and symptoms

• Nicotiana benthamiana - systemic chlorotic mottle.
• Nicotiana clevelandii - systemic chlorotic mottle, sometimes with veinal necrosis.
• Chenopodium amaranticolor, C. quinoa - chlorotic local lesions; not systemic.

Diagnostically insusceptible host species

Beta vulgaris, Brassica campestris, B. campestris ssp. rapa, Cucumis sativus, Lilium formosanum.

Maintenance and propagation hosts

Nicotiana benthamiana, N. clevelandii.

Assay hosts (Local lesions or Whole plants)

Chenopodium amaranticolor (L).

Sources of host-range data

Mowat (1985).

Physical and biochemical properties

Properties of particles in sap

TIP: 50-60 °C. DEP: log₁₀ minus 3. Leaf sap contains few virions (probably).

Purification method

Mowat (1985).

Particle morphology

Virions filamentous; usually flexuous; with a clear modal length; of 720 nm; 12 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations, or two sedimenting components in purified preparations.

Cytopathology

Other cellular changes: interference with pigment formation in petals (Mowat, 1985).

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Bean yellow mosaic virus.

Virus(es) with serologically unrelated virions

Tulip breaking, pepper veinal mottle, tobacco etch and potato Y viruses.

Best tests for diagnosis

Ability to infect Chenopodium amaranticolor, C. quinoa and failure to react with antiserum to tulip breaking virus virions.
