Clover proliferation phytoplasma: ‘Candidatus Phytoplasma trifolii’
International Journal of Systematic and Evolutionary Microbiology, 2004Clover proliferation phytoplasma (CPR) is designated as the reference strain for the CP phylogenetic group or subclade, on the basis of molecular analyses of genomic DNA, the 16S rRNA gene and the 16S–23S spacer region. Other strains related to CPR include alfalfa witches'-broom (AWB), brinjal little leaf (BLL), beet leafhopper-transmitted virescence ...

The possibility to grow phytoplasmas in complex media as the mycoplasmas was ruled out for more than 40 years due to the inconsistency of the first isolation trials. The use of micropropagated infected periwinkle shoots first and tissues infected directly from the fields on artificial media was recently confirmed.

Phytoplasmas are associated with diseases in several hundreds of cultivated herbaceous and woody plants. Their impact in agriculture and the periodical outbreak of worrying epidemics make very important, besides precise laboratory-based diagnosis, the direct in-field recognition of phytoplasma disease symptoms. Even if some symptoms are typical of this

Phytoplasma Proteomic Analysis
2012Proteome analysis is becoming a powerful tool in the functional characterization of organisms, and takes a broad, comprehensive, systematic approach to understanding biology. Following the sequencing of the phytoplasma genomes, the next step is to characterize the expressed proteome of phytoplasmas to acquire the verification and functional annotation ...

A summary of the research carried out on phytoplasma-associated diseases 50 years after their discovery is presented. The great majority of the research was devoted to classification and differentiation of these prokaryotes by molecular and bioinformatic tools applied to specific phytoplasma genes. The availability of a robust classification system has

Candidatus phytoplasma Rubi (witches'-broom phytoplasma disease).
2021Abstract RUS is of considerable economic importance, especially in areas where outbreaks occur. It has been described as a serious and widespread problem of raspberry in the former Soviet Union (see van der Meer (1987) for references). After the First World War, the disease became disastrous in raspberry areas in southern parts of The ...

The present chapter focuses on phytoplasmas and phytoplasma diseases affecting stone, pome, and small fruit worldwide. An outlook is also provided on other fruit tree species growing mainly in tropical and subtropical areas that are oftern infected by phytoplasma diseases usually associated with crop losses or loss of fruit quality and marketability.
