Host range and symptoms

Natural host range and symptoms

Symptoms none.
• Abelia grandiflora - symptomless.

Transmission

Virus transmitted by mechanical inoculation.

Geographical distribution

Spreads in the North American region; the USA (eastern).

Experimental host range

Physical and biochemical properties

Properties of particles in sap

TIP: 74-78 °C. LIV: more than 50 days. DEP: log₁₀ minus 8-9. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains many virions.

Purification method

Waterworth et al. (1975).

Particle morphology

Virions isometric; not enveloped; 25 nm in diameter; rounded in profile.

Physical properties

Two sedimenting components in purified preparations; sedimentation coefficient of the fastest 114 S (B); of the other(s) 54 S (T). A₂₆₀/A₂₈₀ ratio 1.71; (B).

Biochemical properties

Virions contain 39 % nucleic acid; 61 % protein; 0 % lipid (B).

Genome consists of RNA; single-stranded; linear. Base composition 13.6 % G; 23.8 % A; 33.5 % C; 29.1 % U. Infectivity retained when deproteinised with phenol or detergent.

Taxonomy and relationships
