Abstract
Double-stranded cDNA copies of the satellite RNA of tomato black ring virus (strain S) have been cloned in pBR322 and sequenced. From these data the primary nucleotide sequence of the satellite RNA was deduced; it contains 1375 nucleotides and a poly(A) tail. Only one long open reading frame was found which codes for a protein of mol. wt. 47873. This sequence is flanked by a 5'-terminal sequence of 13 nucleotides and a 3' non-coding region of 87 nucleotides, which contains a sequence that resembles signals for polyadenylation in other RNA molecules.
