Prune dwarf virus (PDV), a pathogen of stone fruit trees worldwide, shows a great variability in its biological, serological and molecular properties. The coat protein sequences of ten PDV variants from different stone fruit tree species in Turkey were determined. The sequence for each variant was 657 nucleotides in length. The phylogenetic analyses of the sequences of the Turkish variants and of additional sequences of other PDV variants from international databases indicate the existence of four groups of PDV variants: one contains cherry variants that differs in group specific conserved amino acids; a second contains one apricot and cherry variants, most members of the group being Turkish variants; a third contains mixed variants from cherry, peach, plum trees and an almond tree; and a fourth contains only variants from almond trees. Based on their hosts, we propose the nomenclature of these groups as cherry I, cherry II, mixed and almond groups, respectively. © 2008 Blackwell Verlag.
