It is now just 20 years since Gomatos and his co-workers at the
Rocke feller University showed that the nucleic acid in reovirus
particles is double-stranded RNA (dsRNA). This discovery created
great excitement, for dsRNA was at that time under intense
investigation as the replicative form of viral genomes consisting
of single-stranded RNA. An equally interesting and important
finding followed soon after: it was found that the reovirus genome
consists, not of a single nucleic acid molecule, but of 10 discrete
"segments," each with its specific sequence content and each
transcribed into its own messenger RNA. It is clear now that these
segments are genes. Not surprisingly, the availability of a viral
genome 10 unlinked genes has permitted some unique lines of in
consisting of vestigation in molecular biology. Mammalian and avian
reoviruses proved to be but the first of several viruses recognized
as sharing Similarity in size and morphology and ge nomes
consisting of 10, II, or 12 separate genes. These viruses are dis
tributed throughout living organisms; among the natural hosts of
mem bers of this virus family are vertebrates, Insects, and plants.
Members of the Reoviridae family differ widely in the virulence
that they exhibit toward their hosts . . For example, the first
discovered mam malian reovirus literally is, as the name signifies,
a "respiratory enteric orphan" virus, that is, a virus unassociated
with disease."
