Chinaberry witches'broom, Ziziphus jujube witches'broom, Mulberry dwarf disease, JWB and Paulownia witches' broom phytoplasmas were identified by comparative studies of PCR amplify of phytoplasmal 16SrDNA、23rDNA and ribosomal protein gene, heteroduplex mobility assay, RFLP of PCR-amplified products (16S rDNA), cloning and sequence analysis of 16SrDNA and rp gene. An efficient procedure for rapid identification and differentiation of phytoplasmas was established, which could identify and differentiate phytoplasma collected from field.
