Abstract

Several of the leafhopper- and planthopper-borne diseases we now know to be caused by viruses that belong to the Reoviridae were studied for many years without their etiological agents being recognized (Lyon, 1910; Fukushi, 1931; L.N. Black, 1944; Biraghi, 1949; Fenaroli, 1949). It was only after the development of suitable purification procedures and other techniques that the viruses were isolated and characterized. The first plant Reoviridae to be purified and studied were wound tumor virus (WTV) in America and rice dwarf virus (RDV) in Japan. It was shown that both had polyhedral particles about 70 nm in diameter (Brakke et al., 1954; Fukushi and Kimura, 1959). More sophisticated electron-microscopic studies established the similarity of WTV and RDV particles to those of reovirus (Bils and Hall, 1962; Fukushi et al., 1962; Vasquez and Tournier, 1962). The similarity was further highlighted when it was demonstrated that these viruses all contained double-stranded RNAs (ds-RNAs) (L.M. Black and Markham, 1963; Gomatos and Tamm, 1963a, b; Miura et al., 1966). Subsequent studies revealed that a number of other viruses with reoviruslike particles from vertebrates, insects, and plants contained dsRNA. Verwoerd (1970) recommended that they be classified in one group, for which he suggested the name diplornaviruses. However, it soon became clear that this name was inappropriate (Wood, 1973), since a number of viruses with dsRNA the particles of which were unlike those of reovirus were isolated from fungi and bacteria (Matthews, 1982). Furthermore, small viruslike polyhedral particles, symptomlessly carried by plants and referred to as cryptic viruses, have also recently been shown to contain dsRNA (Lisa et al., 1981).
