Physical and biochemical properties

Properties of particles in sap

TIP: 50 °C. LIV: 0.33 days (at c. 18ºC). DEP: log₁₀ minus 4. Leaf sap contains few virions.

Particle morphology

Virions rhabdo- or bullet-shaped; enveloped; usually straight; with a clear modal length; of 270-350 nm; 45-57 nm wide.

Cytopathology

Virions found in leaves and mesophyll; in cytoplasm (within cisternae of endoplasmic reticulum).
