Abtract

A new potexvirus affecting ornamental allium spp in the Netherlands was identified and characterized at the molecular level. The virus had a single-stranded RNA genome of 7100 bp (excluding the 18 bp poly A tail). The genome organization was found to be typical of members of the genus Potexvirus and consisted of five open reading frames (ORF). Nucleotide and amino acid sequence comparisons with those of known potexvirus members showed that this virus is related to Hosta virus X and Hydrangea ringspot virus. Sequence similarities and phylogenetic relationships suggested that the allium virus is a new and distinct species in the genus Potexvirus and the name, Allium virus X (AlVX) is proposed.
