Sequence analysis showed that the amplified 16S rDNA fragment was closely related to those in the 16Sr Ⅰgroup, with a homology rate of more than 99 %. This fragment had maximum homology, upto 100 %, with those of Ash witches' broom, Epilobium phyllody, and Chinaberry witches' broom phytoplasma strain Jiangxi.
