Abstract

Sequence data have been determined for 5 members of subgroup 2 of the genus Ilarvirus. These data support the known serological relationships among accepted members of this group and indicate that the ilarvirus Hydrangea mosaic virus (HdMV) is an isolate of Elm mottle virus (EMoV). The close relationships between members of this subgroup, exhibited through the coat proteins coded on RNA 3, extend to the other genomic molecules. Primers designed from the sequences of RNA 1 and RNA 2 of EMoV amplified fragments from all other subgroup 2 viruses but not from other ilarviruses. Although closely related, members of this subgroup occur naturally in distinctly different host species. The possible origins of the viruses are discussed in relation to similarities among the genomic molecules, in particular RNA 3.
