The complete nucleotide sequence of prune dwarf ilarvirus RNA-1.

The sequence of prune dwarf ilarvirus (PDV) RNA-1 has been determined; it consists of 3,374 nucleotides and contains a single open reading frame of 3,168 nucleotides. The putative translation product is 1,055 amino acids in length with a calculated molecular mass of 118.9 kDa. Both the nucleic acid and the translated amino acid sequences show stronger homology to the corresponding RNA-1 and ORF-1 of apple mosaic ilarvirus and alfalfa mosaic alfamovirus than to spinach latent mosaic ilarvirus or citrus leaf rugose ilarvirus. These findings are consistent with the inclusion of alfalfa mosaic virus in the ilarvirus genus. The reported sequence of PDV RNA-1 and its single ORF conform to the genomic organization typical of the Bromoviridae family.
