Physical and biochemical properties

Properties of particles in sap

DEP: log₁₀ minus 2-4. Leaf sap contains many virions.

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 780 nm; 11 nm wide. Axial canal obscure. Basic helix obscure.

Cytopathology

Virions found in leaves, mesophyll and epidermis; in cytoplasm. Inclusions present in infected cells; are pinwheels and unusual in shape; and tubular structures; they contain virions. Other cellular changes: pinwheel and tubular inclusions, large masses of virions, nuclei with invaginations containing mitochondria.

Taxonomy and relationships

Potyvirus: Potyviridae
