1. Detection and molecular characterization of cactus witches'-broom disease associated with a group 16SrII phytoplasma in northern areas of China
In July 2010, cacti with typical phytoplasma symptoms were observed in Yangling district, Shaanxi Province, China. Based on amplification of 16S rRNA gene, phytoplasmas were detected by polymerase chain reaction (PCR) driven with universal primer pairs P1/ P7, followed by a nested PCR with universal primer pairs R16F2n/R16R2. Fragments of expected sizes (1.8

2. Molecular characterization and phylogenetic analysis of the phytoplasma agent of the witchesbroom of cassava (Manihot esculenta) in São Paulo State. / Caracterização molecular e análise filogenética do fitoplasma agente do superbrotamento da mandioca (Manihot esculenta) no estado de São Paulo
A mandioca (Manihot esculenta) é uma das principais culturas exploradas no mundo, sendo o Brasil o segundo maior produtor. Cultivada em todas as regiões brasileiras, a mandioca é importante na indústria e na alimentação humana e animal. Em plantios instalados em campo experimental e comercial, nas cidades de Piracicaba/SP e Bragança Paulista/SP, respe

3. Passion fruit proliferation phytoplasma: molecular identification, phylogenetic analysis and proof of pathogenicity / Fitoplasma do superbrotamento do maracujazeiro: identificação molecular, análise filogenética e prova de patogenicidade
Phytoplasmas are cell wall-less prokaryotes and phloem-inhabitants associated with diseases that affect several crops. Passion fruit plant is a tropical species cultivated in various Brazilian regions. Diseases are among factors that may cause damage to this crop and the passion fruit witchesbroom has been revealed as very important one. That disease, associ

4. Mycoplasmalike organisms (MLOs) and distinguish them from other MLOs.
DNA of 10 lines of rice yellow dwarf (RYD) mycoplasmalike organisms (MLOs) from Japan, the Phillippines, and Thailand hybridized with four probes containing chromosomal and six probes containing extrachromosomal DNA of a Tochigi (Japan) line of RYD MLO. One chromosomal probe (RYD9) and all six extrachromosomal probes hybridized with various other MLOs (sugar

5. Genetic Interrelatedness among Clover Proliferation Mycoplasmalike Organisms (MLOs) and Other MLOs Investigated by Nucleic Acid Hybridization and Restriction Fragment Length Polymorphism Analyses
DNA was isolated from clover proliferation (CP) mycoplasmalike organism (MLO)-diseased periwinkle plants (Catharanthus roseus (L.) G. Don.) and cloned into pSP6 plasmid vectors. CP MLO-specific recombinant DNA clones were biotin labeled and used as probes in dot hybridization and restriction fragment length polymorphism analyses to study the genetic interrel

6. Phylogeny of mycoplasmalike organisms (phytoplasmas): a basis for their classification.
A global phylogenetic analysis using parsimony of 16S rRNA gene sequences from 46 mollicutes, 19 mycoplasmalike organisms (MLOs) (new trivial name, phytoplasmas), and several related bacteria placed the MLOs definitively among the members of the class Mollicutes and revealed that MLOs form a large discrete monophyletic clade, paraphyletic to the Acholeplasma
