Nucleotide Sequence of Papaya Mosaic Virus RNA Sit, T. L. and Abouhaidar*, M. G. and Holy, S.,, 70, 2325-2331 (1989), doi = https://doi.org/10.1099/0022-1317-70-9-2325, publicationName = Microbiology Society, issn = 0022-1317, abstract= Summary 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 M r 176307, 26248, 11949 and 7224 (ORFs 1 to 4). The fifth ORF produces the capsid protein of M r 23043 and the sixth ORF, located completely within ORF1, could code for a protein with M r 14113. The translation products of ORFs 1 to 3 show strong similarity with those of other potexviruses but the ORF 4 proteinhas only limited similarity with the other potexvirus ORF 4 proteins of 7K to 11K., language=, type=
