Based on Phylogenetic analysis of sequences from these 10 phytoplasmas using PAUP (phylogenetic analysis using parsimony) software, these phytoplasmas could be classified into five groups. These phytoplasmas groups and strains were: group 1, sweetpotato witches' broom, mainland China strain of sweetpotato witches' broom, peanut witches' broom and Ipomoea obscura witches' broom; group 2, loofah witches' broom; group 3, elm yellows; group 4, rice yellow dwarf and sugarcane white leaf disease; group 5, New Jersey strain of aster yellows and western strain of aster yellows.

从spacer序列堆衍的亲缘演化树显示这10种植物菌质体可分为5群：第一群，甘薯簇叶病、甘薯簇叶病、花生簇叶病及细花牵牛簇叶病等菌质体；第二群，丝瓜簇叶病菌质体；第三群，榆树黄化病菌质体；第四群，水稻黄萎病及甘蔗白叶病菌质体；第五群，翠菊黄化病菌质体。

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. Its similarity of 16S rDNA sequence is obviously lower than 97 % as compared with other phytoplasma groups.

结果表明，该片段与16Sr I组中的各植原体同源率均达到99 %以上，其中与16Sr I中的白蜡树丛枝（Ash witches'-broom，AWB，AY566302），柳叶菜变叶（Epilobium phyllody，EP，AY101386）和苦楝丛枝江西株系（Chinaberry witches'-broom，CWB-JX，AY859543）的同源率最高，达到100 %，而与其它组的植原体16S rDNA序列的同源率均低于97 %。

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.

通过对桑萎缩病、枣疯病、酸枣丛枝病、泡桐丛枝病和苦楝丛枝病植原体16SrDNA、23SrDNA和核糖体蛋白基因的PCR扩增、异源双链迁移率分析、16SrDNA PCR产物的限制性片段多态性分析以及植原体16SrDNA和rp基因的克隆和序列分析等比较研究，建立了一种快速确定未知植原体种类和分类地位的分子鉴别与鉴定优化程序；此程序可对田间采集的各种植物植原体样品直接进行快速鉴定和鉴别。

The phytoplasmas diseases were investigated in 30 counties and cities of 10 areas in Yunnan Province. There are 12 phytoplasma diseases, including paulownia witches-broom,chinaberry witches-broom, cactus witches-broom, christmas cactus witches-broom, orange little leaf, petunia flat stem and so on were indentified using PCR with universal primers, which amplified phytoplasma 16SrRNA gene and/or ribosomal protein genes. So the kind of phytoplasma diseases in Yunnnan Province were understood. Identified the characteristic of 16SrRNA and rp gene of phytoplasma and the kind, classification and genitic relativity of these strains using RFLP, clonging and sequence analysis (nearly 20 full-length sequences of phytoplasma 16SrRNA and/or rp gene were submitted in GenBank ); The phytoplasma strains isolated from herbage plants were conserved in storeroom. 9 articles were published in the key journals of China and 1 technique invention patent was applied. The net-page about phytoplasma disease was established. 4 graduate student were bringed up.
