Prickly ash trees with shortened internodes, proliferation of shoots, phyllody and witches' brooms were observed for the first time in K orea. A phytoplasma was detected in infected trees by polymerase chain reaction amplification of 16S rDNA , 16 S –23 S intergenic spacer region and the fragment of rp operon sequences. The 16S rDNA sequences exhibited maximum (99.6%) similarity with Iranian lettuce phytoplasma, and the sequences of rp operon exhibited maximum (100%) similarity with golden rain phytoplasma. Based on the sequence analysis and phylogenetic studies, it was confirmed that phytoplasma infecting prickly ash trees in K orea belongs to the aster yellows group (subgroup 16 S r I ‐ B ).
