| Abstract: | Northern blot analysis with random-primed cDNAs revealed that RNAs 1 and 2 of barley yellow mosaic virus (Ba YMV) isolate M have no extensive base sequence homologies. Both RNAs are needed for infection. RNA 2 is therefore neither a subgenomic nor a, satellite RNA, but rather an essential part of the viral genome. Ba YMV isolate M has thus a bipartite genome. |
