Sources of host-range data

Physical and biochemical properties

Properties of particles in sap

Leaf sap contains few virions.

Purification method

Lockhart et al. (1981).

Particle morphology

Virions filamentous; not enveloped; usually flexuous; with a clear modal length; of 754 nm. Axial canal obscure.

Physical properties

One sedimenting component in purified preparations.

Cytopathology

Inclusions present in infected cells; are pinwheels; they do not contain virions.

Taxonomy and relationships

Potyvirus: Potyviridae

Virus(es) with serologically unrelated virions

Bean common mosaic, bean yellow mosaic, bidens mottle, blackeye cowpea mosaic, commelina mosaic, dasheen mosaic, maize dwarf mosaic, papaya ringspot, pepper mottle, potato Y, tobacco etch and watermelon mosaic viruses. It is not known if it is related to potyviruses reported in Commelina diffusa in Guadeloupe (Migliori and Lastra, 1978) and in 12 species of Commelinaceae in Florida, U.S.A. (Baker and Zettler, 1986).
