Taxonomy and relationships

Probably Potyvirus: Potyviridae

Virus(es) with serologically unrelated virions

Tobacco etch virus.

Additional comments on relationships

Datura mosaic virus is a potyvirus, but its relationships with others are uncertain (Hollings and Brunt, 1981).

Best tests for diagnosis

Datura shoestring virus (DSV) differs from DMV in its failure to infect Datura stramonium, D. innoxia and Solanum nigrum. Datura distortion mosaic virus (DDMV) differs from DMV in its failure to induce local lesions in Datura species and in being transmissible by aphids. Datura species are known to be naturally infected by other potyviruses such as datura necrosis virus (DNV) (Badami and Kassanis, 1959), datura Colombian virus (DCV) (Kahn and Bartels, 1968), datura shoestring virus (DSV) (Giri and Agrawal, 1971) and datura distortion mosaic virus (DDMV) (Mali et al., 1985). However, they differ in various properties; DNV infects Lycopersicon esculentum, which is insusceptible to DMV; DCV incites few or no symptoms in Datura stramonium, D. metel and Nicotiana tabacum var. Samsun, is transmitted by Myzus persicae, and has a greater LIV; DMV incites severe symptoms in Datura species, is not transmitted by aphids and has a short LIV; DMV, unlike DSV, induces local lesions in Datura species; DSV, unlike DMV, induces lesions in Nicotiana rustica and does not infect Datura stramonium, D. innoxia and Solanum nigrum. DDMV differs from DMV in being aphid transmitted and able to infect Capsicum annuum but not cause local lesions in Datura species (Mali, 1985). The virion morphology of other Indian viruses infecting Datura (Capoor and Verma, 1948; 1951; Garga, 1958; Verma and Verma, 1963; Yaraguntaiah and Govindu, 1973) is not known.
