E. Seemuller et al., PERSISTENCE OF THE EUROPEAN STONE FRUIT YELLOWS PHYTOPLASMA IN AERIALPARTS OF PRUNUS-TAXA DURING THE DORMANT SEASON, Journal of phytopathology, 146(8-9), 1998, pp. 407-410
Fluorescence microscopy and PCR as well as graft transmission experime
nts were employed to examine the persistence of the European stone fru
it phytoplasma in the stem of various Prunus taxa during the dormant s
eason. Both approaches revealed that the phytoplasma pathogen persists
in the aerial parts of the trees in all stone fruit taxa examined.
