Abstract
The nucleotide sequences of cDNA clones corresponding to the 3'' OH end of papaya mosaic virus RNA have been determined. The 3''-terminal sequence obtained was 900 nucleotides in length, excluding the poly(A) tail, and contained an open reading frame capable of giving rise to a protein of 214 amino acid residues with an Mr of 22,930. This protein was identified as the viral capsid protein. The 3'' non-coding region of PMV genome RNA was about 121 nucleotides long [excluding the poly(A) tail] and homologous to the complementary sequence of the non-coding region at the 5'' end of PMV RNA. A long open reading frame was also found in the predicted 5'' end region of the negative strand.
