Different PCR protocols have been established for detection of European fruit trees phytoplasmas; however the majority of the procedures for extracting phytoplasma DNA are complex, time consuming, and expensive, with a risk of contamination or loss of target DNA. In present study, a crude extract preparation method previously used to detect other plant pathogens was adapted to samples from appl...

"Candidatus Phytoplasma aurantifolia" is associated with witches' broom disease of lime in Oman and the UAE. A previous study showed that an infection by phytoplasma may not necessarily result in the physical appearance of witches' broom symptoms in some locations in Oman and the UAE. This study investigated whether phytoplasma strains belonging to "Ca. P. aurantifolia" (based on the 16S rRNA g...

In Korea, Japanese chestnut trees (Castanea crenata Sieb. and Zucc.) showing symptoms indicative of witches' broom disease, including abnormally small leaves and yellowing of young leaves, were examined. Since the symptoms were suggestive of a phytoplasma infection, tissues were assayed for phytoplasmas by PCR analysis using a pair of universal primers that amplify a 1.4-kbp phytoplasma 16S rDN...

During the last two decades, over 800 phytoplasma strains have been reported in association with several hundred plant diseases and numerous insect vectors. Research has yielded new knowledge about phytoplasma ecology and phylogenetic relationships. A taxonomic system has emerged, and perspectives on phytoplasma speciation have changed. Guidelines for naming new ‘Candidatus Phytoplasma’ species...

Ribosomal (r) RNA interoperon sequence heterogeneity in the 'Fragaria multicipita' phytoplasma, a member of group 16SrVI, was initially observed in RFLP patterns of rDNA amplified in the polymerase chain reaction (PCR), and was confirmed through sequence analysis of cloned rDNA. Sequences from operons rrnA and rrnB were amplified in PCR primed by primer pair P1/P7 but from only rrnA in PCR prim...

The chromosome sequence of "Candidatus Phytoplasma australiense" (subgroup tuf-Australia I; rp-A), associated with dieback in papaya, Australian grapevine yellows in grapevine, and several other important plant diseases, was determined. The circular chromosome is represented by 879,324 nucleotides, a GC content of 27%, and 839 protein-coding genes. Five hundred two of these protein-coding genes...

To The ediTor Recently, Lin and colleagues have reported a case of pyridoxine-dependent seizures in this journal 1. The diagnosis was based upon the clinical criteria as formulated by Baxter 2. In discussing the case the authors state that the underlying pathophysiology of the disorder is unknown and that no biochemical aids are available in establishing the diagnosis. Indeed, for 50 years pyri...

Global interest on plant-microbe-insect interactions is rapidly growing, revealing the multiple ways in which microorganisms mediate plant-herbivore interactions. Phytopathogens regularly alter whole repertoires of plant phenotypic traits, and bring about shifts in key chemical or morphological characteristics of plant hosts. Pathogens can also cause cascading effects on higher trophic levels, ...

The bacterial genus "Candidatus Phytoplasma" contains a group of insect-transmitted plant pathogens in the class Mollicutes. Here, we report a draft genome assembly and annotation of strain NCHU2014, which belongs to the 16SrII-A subgroup within this genus and is associated with purple coneflower witches' broom disease in Taiwan.
