Host range and symptoms

Natural host range and symptoms

Symptoms persist. Symptoms curling, dwarfing and chlorosis of tip leaves.
• Solanum tuberosum - upward rolling, narrowing and dwarfing of tip leaflets. Red or purple discoloured leaflet bases. Tubers do not sprout or produce short, thin sprouts.
• Solanum basendopogon, S. basendopogon f. obtusum - mild chlorosis of apical leaves.
• Nicandra physalodes - chlorosis.
• Physalis peruviana - stunting and chlorosis with green leaf veins.
• Datura tatula - vein yellowing, tip leaves curled downward and dwarfed. Severe chlorosis in older infections.

Transmission

Probably transmitted by leafhoppers. Not transmitted by Myzus persicae. Virus not transmitted by mechanical inoculation; transmitted by grafting; not transmitted by contact between plants; not transmitted by seed; not transmitted by pollen.

Geographical distribution

Spreads in Peru.

Experimental host range

Few (<3) families susceptible. Experimentally infected plants mostly show curling, dwarfing and chlorosis.

Diagnostically susceptible host species and symptoms

• Datura tatula, D. stramonium, Nicotiana benthamiana - curling, dwarfing and chlorosis of apical leaves.
• Solanum nigrum - chlorosis.
• Lycopersicon esculentum, Nicandra physalodes - symptomless.

Maintenance and propagation hosts

Nicotiana benthamiana, Datura tatula, D. stramonium, Lycopersicon esculentum.

Assay hosts (Local lesions or Whole plants)

Datura tatula (W), Datura stramonium (W).

Susceptible host species

• Datura stramonium
• Datura tatula
• Lycopersicon esculentum
• Nicandra physalodes
• Nicotiana benthamiana
• Physalis peruviana
• Solanum basendopogon
• Solanum basendopogon f. obtusum
• Solanum nigrum
• Solanum tuberosum

Families containing susceptible hosts

• Solanaceae (10/10)

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Hooker and Salazar (1983).

Particle morphology

Virions geminate, or unusually shaped; trisegmented virions; not enveloped; 17 nm in diameter; up to 52 nm in length; without a conspicuous capsomere arrangement.

Physical properties

Three sedimenting components in purified preparations (usually, but 1 or 2 components seen in some preparations).

Biochemical properties

Genome consists of DNA; single-stranded; circular.

Cytopathology

Virions found in leaves, phloem and companion cells.

Taxonomy and relationships

Possible bigeminivirus: Geminiviridae

Best tests for diagnosis

Serology (ELISA).
