Physical and biochemical properties

Properties of particles in sap

TIP: 60 °C. LIV: 16 days. DEP: log₁₀ minus 4.

Particle morphology

Virions filamentous; usually flexuous; with a clear modal length; of 760 nm.

Cytopathology

Virions found in leaves and mesophyll; in cytoplasm. Inclusions present in infected cells; are pinwheels; they do not contain virions.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically related virions

Bean yellow mosaic and lettuce mosaic viruses.

Virus(es) with serologically unrelated virions

Iris severe mosaic, carnation vein mottle, henbane mosaic and potato Y viruses.

Comments and References

General comments

It is not known whether a primula mosaic virus in the U.S.A. (Tompkins and Middleton, 1941) has any relationship to that described here. The closeness of the serological relationship between primula mosaic and lettuce mosaic viruses (SDI 2-3) suggests that the former could be regarded as a strain of lettuce mosaic potyvirus.
