RELATEDNESS OF THE NUCLEOTIDE-SEQUENCE OF THE 3'-TERMINAL REGION OF CLOVER YELLOW VEIN POTYVIRUS RNA TO BEAN YELLOW MOSAIC POTYVIRUS RNA

The sequence of the 3'-terminal 1,357 nucleotides of clover yellow vein potyvirus RNA was determined. A coat protein gene was identified and its predicted amino acid sequence deduced. It had 273 residues with a molecular weight of 31,019. The amino acid and nucleotide sequences of the virus were compared with those of five other potyviruses. The homology between these viruses indicated that clover yellow vein virus was a distinct virus, but had a closer affinity to bean yellow mosaic virus than to the four other potyviruses.
