Abstract:
The RNA genome of papaya mosaic virus is 6656 nucleotides long [excluding the poly(A) tail] with six open reading frames (ORFs) more than 200 nucleotides long. The four nearest the 5' end each overlap with adjacent ORFs and could code for proteins with Mr 176307, 26248, 11949 and 7224 (ORFs 1 to 4). The fifth ORF produces the capsid protein of Mr 23043 and the sixth ORF, located completely within ORF1, could code for a protein with Mr 14113. The translation products of ORFs 1 to 3 show strong similarity with those of other potexviruses but the ORF 4 protein has only limited similarity with the other potexvirus ORF 4 proteins of 7K to 11K.
