E. Peerenboom et al., A LARGE DUPLICATION IN THE 3'-UNTRANSLATED REGION OF A SUBPOPULATION OF RNA2 OF THE UK-M ISOLATE OF BARLEY MILD MOSAIC BYMOVIRUS, Virus research, 47(1), 1997, pp. 1-6
The UK-M isolate of the bipartite barley mild mosaic bymovirus (BaMMV
UK-M) cannot be fungally transmitted, and has previously been shown to
have a 1092 nt deletion in the coding region of RNA2. We now report,
using sequence and reverse transcriptase-polymerase chain reaction (RT
-PCR) data, that a subpopulation of BaMMV UK-M RNA2 contains a direct
imperfect sequence repeat of 552 nt in the 3' untranslated region. The
secondary structure of the 3' end of RNA2, and its possible effects o
n replication of the virus, are also discussed. (C) 1997 Elsevier Scie
