Twenty strains of the European stone fruit yellows (ESFY) phytoplasma showed great differences in virulence when examined by graft inoculation of trees on peach, peach hybrid GF 677 and P. Marianna' GF 8/1 rootstocks. The most virulent strains killed

For competitive polymerase chain reaction (PCR), an internal standard DNA template was developed that consisted of a highly conserved, internally deleted 16S rDNA fragment of an aster yellows phytoplasma. The internal standard was calibrated using a

Fluorescence microscopy and PCR as well as graft transmission experiments were employed to examine the persistence of the European stone fruit phytoplasma in the stem of various Prunus taxa during the dormant season. Both approaches revealed that the
