Phytoplasmas are a severe threat to agriculture in many countries causing serious yield losses in a wide range of economically important crops. They exhibit a unique life cycle compared with other plant pathogenic bacteria, which make them difficult to control.

INSECT VECTORS OF PHYTOPLASMAS
Annual Review of Entomology, 2006▪ Abstract Plant diseases caused by, or associated with, phytoplasmas occur in hundreds of commercial and native plants, causing minor to extensive damage. Insect vectors, primarily leafhoppers, planthoppers, and psyllids, have been identified for relatively few phytoplasma diseases, limiting the capacity of managers to make informed decisions to ...

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.

Phytoplasmas is a class of bacteria that is pathogenic to a wide variety of plant species, and was first identified in 1967. It is characterized by its small genome size, ranging from 0.3 to 1.2 micrometers, and polymorphic polymorphism. It is important for agriculture to identify the factors that contribute to its pathogenicity, as well as to identify

Mapping the Phytoplasma Chromosome
2012Physical and genetic mapping of the phytoplasma chromosome can be a useful tool in a genome sequencing project in order to assemble the in silico-predicted contigs robustly. Mapping consists of four distinct steps: preparation of phytoplasma chromosomes from infected plants, single- and double-digestion of chromosomes with rare-cutting restriction ...

Transcriptomic Analyses of Phytoplasmas
2018Transcriptomic analyses addressed to study phytoplasma gene expression may present few difficulties due to the uncultivable nature of these intracellular, obligate pathogens. While RNA extraction from insect vectors does not imply any particular adaptation of the protocols used in most commercial kits, RNA isolation from phytoplasma-infected plants can

Phytoplasma Diseases of Palms [PDF]
, 2018 Palms are native to tropical and subtropical areas of the world and con-tribute to the ecology and economy of many countries. Phytoplasmas which are cell-wall-less prokaryotes are associated with diseases of significant economic importance to palms worldwide.

Phytopathogenic Mollicutes, 2023
The use of ‘Candidatus Phytoplasma’ as provisional taxon is helping both epidemiological studies and quarantine rules settling. A focused search in database evidences discrepancies and problems for strains enclosed in ‘Ca. P. aurantifolia’ and ‘Ca. P. australasia’ that share very often the same geographic distribution in Asian and Australian countries.
