Sources of host-range data

Physical and biochemical properties

Properties of particles in sap

TIP: 60 °C. LIV: 4 days (at 25-28ºC). DEP: log₁₀ minus 4. Leaf sap contains few virions.

Purification method

Ladipo et al. (1976).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 820 nm. Axial canal obscure. Basic helix obscure.

Cytopathology

Virions found in leaves; in cytoplasm. Inclusions present in infected cells; are pinwheels; they do not contain virions. Other cellular changes: masses of endoplasmic reticulum, microbodies, lipid droplets, mitochondria and abnormal vesicles in cytoplasm.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Dioscorea green-banding, groundnut eyespot, zucchini yellow mosaic and an unnamed potyvirus from tomato in Taiwan.

Virus(es) with serologically unrelated virions

Datura Colombian, henbane mosaic, pepper mottle, pepper veinal mottle, tomato (Peru), potato A, potato Y, tobacco etch and wild potato mosaic viruses.
