The genome segments of DpRV, a commensal reovirus of the wasp Diadromus pulchellus (hymenoptera)

Abstract

The complete nucleotide sequences of five double-stranded RNA genome segments of the Diadromus pulchellus reovirus (DpRV) have been determined. They consist of 985, 1240, 1318, 1652, and 4230 bp. Each segment contains at least one putative open reading frame encoding 33-, 40-, 45-, 49-, and 148- kDa proteins, respectively. The proteins have no significant similarities with sequences in data banks. Analysis of these segments and of two other previously published segments revealed the presence of degenerate consensus inverted repeats at both ends (5'-rCAAUUUUnnACU…AGUAAAAAAAUnrG-3'). The biological, structural, and genomic features of DpRV suggest that this virus is related to members of the Orthoreovirus genus. © 1995 Academic Press, Inc.
