Sources of host-range data

Giri and Agrawal (1971).

Physical and biochemical properties

Properties of particles in sap

TIP: 60-65 °C. LIV: 1-2 days. DEP: log₁₀ minus 4. Leaf sap contains many virions. Electron microscopy: 2% PTA-Na, pH 7.

Purification method

Brunt and Stace-Smith (1973).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 720-750 nm; 16 nm wide. Axial canal obscure. Basic helix usually obscure (but sometimes visible in thin sections).

Physical properties

One sedimenting component in purified preparations; sedimentation coefficient 143 S. Density 1.33 g cm^-3 in CsCl.

Features of proteins

Virion protein(s) one; M_r 36600 (degrades to 27400). Method of preparation: Agrawal and Tremaine (1972).

Cytopathology

Virions found in leaves and mesophyll; in cytoplasm. Inclusions present in infected cells; are crystals in the cytoplasm, amorphous X-bodies, pinwheels, and unusual in shape; tubules in the nucleus; they do not contain virions (although long helical structures are found near virus aggregates). Other cellular changes: drastic reduction of leaf lamina.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Pepper veinal mottle virus.

Virus(es) with serologically unrelated virions

Potato virus Y.
