Physical and biochemical properties

Properties of particles in sap

TIP: 65-66.75-70 °C. LIV: 3-3.25-4 days. DEP: log₁₀ minus 3-4. Infectivity of sap not changed by treatment with di-ethyl ether (1/1). Leaf sap contains few virions (1), or contains many virions (1).

Particle morphology

Virions filamentous; not enveloped; usually straight (1), or usually flexuous (1); with a clear modal length; of 657-664.5-672 nm; 13-13.75-16 nm wide. Axial canal obscure. Basic helix obscure.

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 155-156-158 S. Density 1.307-1.316-1.33 g cm^-3 in CsCl. A₂₆₀/A₂₈₀ ratio 1.04-1.065-1.09.

Biochemical properties

Virions contain 3-4.25-5 % nucleic acid; 95-95.75-97 % protein; 0 % lipid.

Genome consists of RNA; single-stranded.

Features of proteins

Virion protein(s) one; M_r 32600-38800-45000.

Replication

Replication does not depend on a helper virus (1/1).

Cytopathology

Virions found in cytoplasm. Inclusions present in infected cells; are amorphous X-bodies (1), or pinwheels.
