查询词典 Paulownia

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.

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.
