Physical and biochemical properties

Properties of particles in sap

Leaf sap contains many virions.

Purification method

Marinho et al. (1985).

Particle morphology

Virions isometric; not enveloped; 30 nm in diameter; angular in profile; without a conspicuous capsomere arrangement.

Physical properties

One sedimenting component in purified preparations. A₂₆₀/A₂₈₀ ratio 1.39.

Biochemical properties

Virions contain 20 % nucleic acid; 80 % protein.

Genome consists of RNA; single-stranded; linear.

Features of proteins

Virion protein(s) one; M_r 31000; coat protein.

Cytopathology

Virions found in all parts of the host plant; in cytoplasm and in cell vacuoles. Inclusions absent from infected cells.

Taxonomy and relationships

(ungrouped)

Virus(es) with serologically unrelated virions

Purple granadilla and maize rayado fino viruses and ilarviruses, sobemoviruses, cucumoviruses, comoviruses and tymoviruses.
