This agent leads to serious damage in apricot and Japanese plum orchards, including decline of infected trees. The consequences are considerable economic losses in production. European plum and cherry are less susceptible to ESFY, although th...

Apple proliferation (AP), pear decline (PD) and European stone fruit yellows (ESFY) are among the most economically important plant diseases that are caused by phytoplasmas. Phylogenetic analyses revealed that the 16S rDNA sequences of strains of each of these pathogens were identical or nearly identical. Differences between the three phytoplasmas ranged from 1.0 to 1.5% of nucleotide positions...
