We have detected a small DNA molecule (sa-DNA), 725 nucleotides long, in cauliflower mosaic virus (CaMV)-infected, but not non-infected, turnip leaves. Alkali and RNase A treatments shortened sa-DNA by 100 nucleotides and we conclude that it contains covalently-linked ribonucleotides. This DNA co-purified with cellular polyadenylated RNA. It is complementary to the beta-strand of CaMV DNA and of opposite polarity to RNAs transcribed from the alpha-strand. Hybridisation studies suggest that sa-DNA originates from the large intergenic region (IR1) of the CaMV genome. A small double-stranded DNA with three single-stranded components, which co-purifies with cellular DNA, appears to be related to sa-DNA but lacks detectable ribonucleotides.
