X-disease phytoplasma is primarily associated with diseases in Prunus avium (sweet cherry), P. cerasus (sour cherry) and P. persica (peach), although it is occasionally associated with decline in P. dulcis (almond) and may infect plum species (Guerra and Eastwell, 2006). Four X-disease phytoplasma strains are reported: Green Valley (GVX), Napa Valley (NVX), Peach yellow leafroll 1 (WX/PYLR1) and the Seibe strain (Guerra and Eastwell, 2006). The GVX strain is most common. GVX and NVX strains are associated with slightly different symptoms in cherry (Nemeth, 1986).
