Physical and biochemical properties

Properties of particles in sap

TIP: 65-70 °C. LIV: 28 days. DEP: log₁₀ minus 6. Infectivity of sap not changed by treatment with di-ethyl ether. Leaf sap contains many virions.

Purification method

Dunn and Hitchborn (1965).

Particle morphology

Virions isometric; not enveloped; 28 nm in diameter; rounded in profile, or angular in profile.

Physical properties

Three sedimenting components in purified preparations; sedimentation coefficient of the fastest 112 S (B); of the other(s) 93 S (M), or 53 S (T). Density 1.41 g cm^-3 in CsCl (M), or 1.46 g cm^-3 in CsCl (B).

Biochemical properties

Virions contain 34 % nucleic acid (B), or 27 % nucleic acid (M), or 0 % nucleic acid (T); 66 % protein (B), or 73 % protein (M), or 100 % protein (T); 0 % lipid.

Genome consists of RNA; single-stranded; linear. Total genome size 11.1 kb. Genome of two parts; largest (or only) genome part the larger 6.5 kb; the 2nd largest 4.6 kb. Genomic nucleic acid isolated by Salazar and Harrison (1978).
