Host range and symptoms

Natural host range and symptoms

• Arachis hypogaea - dark green spots with chlorotic halos and dark green line patterns on leaflets.
• Physalis floridana - mild mosaic leaf symptoms.

Transmission

Transmitted by a vector; an insect; Aphis craccivora; Aphididae. Transmitted in a non-persistent manner. Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in Cote d'Ivoire.

Experimental host range

Several (3-9) families susceptible.

Maintenance and propagation hosts

Sources of host-range data

Dubern and Dollet (1980).

Physical and biochemical properties

Properties of particles in sap

TIP: 44 °C. LIV: 0.125 days (3 hours). DEP: log₁₀ minus 3-4. Leaf sap contains few virions.

Purification method

Dubern and Dollet (1980).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 755 nm; 12.5 nm wide.

Physical properties

One sedimenting component in purified preparations.

Biochemical properties

Virions contain 5.5-6.5 % nucleic acid (from A₂₆₀/A₂₈₀ ratio (Layne 1977)).

Cytopathology

Virions found in all parts of the host plant; in cytoplasm. Inclusions present in infected cells; are pinwheels; they do not contain virions.
