The entire nucleotide sequence and genomic organization of potato aucuba mosaic potexvirus

The entire nucleotide sequence (7057 nucleotides) of cDNA clones of potato aucuba mosaic virus (PAMV) was determined. The genome contains five major putative open reading frames (ORFs), designated from the 5' terminus as encoding putative proteins with M(r) of 187,379 (187 K), 26,326 (26 K), 12,101 (12 K), 8,183 (8 K) and 27,114 (27 K). The genomic organization of PAMV is essentially the same as that of several other potexviruses. The sizes and composition of the proteins encoded by the ORFs are generally similar to those found in other potexviruses. The genome and the capsid protein gene of PAMV, are the largest among the potexviruses sequenced to date.
