Mallotus japonicus with witches' broom disease were observed in J eollabuk‐do, K orea. A phytoplasma from the infected leaves was identified, based on the 16S rDNA , 16S‐23S intergenic spacer region, and fragment of rp operon and tuf gene sequences. The 16S rDNA sequences exhibited maximum (99.7%) similarity with Iranian lettuce phytoplasma, the rp operon sequences exhibited 100% similarity with G oldenrain stunt phytoplasma, and the tuf gene sequences exhibited 99.8% similarity with Japanese spurge yellows phytoplasma. Results of the sequence analysis and phylogenetic studies confirmed that the phytoplasma associated with M . japonicus in K orea was an isolate of A ster Y ellows group (subgroup16SrI‐B).
