Diversity of phytoplasmas identified in the polyphagous leafhopper Euscelis incisus (Cicadellidae, Deltocephalinae) in Serbia: pathogen inventory, epidemiological significance and vectoring potential
The interactions of E. incisus with phytoplasmas in different ecosystems as a bioindicator of phyToplasma diversity was investigated and leafhoppers successfully transmitted stolbur phy toplasma to exposed Catharanthus roseus plants, indicating their role as a natural vector. Expand
‘Candidatus Phytoplasma solani’ interferes with the distribution and uptake of iron in tomato
‘Candidatus Phytoplasma solani’ infection changes the Fe distribution in tomato leaves, affects the photosynthetic machinery and perturbs the orchestration of root-mediated transport processes by compromising shoot-to-root communication. Expand
Insight into epidemiological importance of phytoplasma vectors in vineyards in South Moravia, Czech Republic
The nested polymerase chain reaction-restriction fragment length polymorphism analyses confirmed Hyalesthes obsoletus as the main BN vector and a significant role of anaceratagallia ribauti should be taken into account based on its occurrence and incidence of infected individuals. Expand
Combined microscopy and molecular analyses show phloem occlusions and cell wall modifications in tomato leaves in response to ‘Candidatus Phytoplasma solani’
A putative callose synthase gene encoding a protein with high similarity to Arabidopsis CalS7, responsible for callose deposition at sieve plates, was upregulated in symptomatic leaves, indicating a modulation in the response to stolbur infection. Expand
Transmission of ‘Candidatus Phytoplasma solani’ by Reptalus quinquecostatus (Hemiptera: Cixiidae)
Observations of adults feeding on grapevines in vineyards consolidate the hypothesis that R. P. quinquecostatus is a specific vector of ‘Ca. solani’ epidemiology, and this planthopper can contribute to maintain an alternative ‘ Ca. solANI’ cycle in weeds even in the absence of H. obsoletus. Expand
A 16SrII-D Phytoplasma strain associated with Tomato Witches'- Broom in Bushehr province, Iran
This is the first report of tomato witches'- broom disease and characterization of its associated phytoplasma in Iran. Expand
Expression of defence genes in stolbur phytoplasma infected tomatoes, and effect of defence stimulators on disease development
Results indicated that the SA-mediated defence response was activated by the stolbur phytoplasma strains PO and C in contrast to the JA-dependent defence pathway which was repressed by strain PO but activated by strain C, suggesting that the two strains might have distinct virulence factors, in agreement with the fact that they induce distinctive symptoms.

A study on the transmission with the seed of stolbur disease in Western Anatolia tomato areas.
The results showed that the role of the seed in spreading of stolbur disease in tomato was not confirmed and total genomic DNA was isolated from seeds and tomato plants and amplified by universal primer sets for phytoplasma. Expand
Experimental proofs regarding the association of cell wall deficient bacteria (mycoplasmalike organisms, phytoplasmas) with grapevine yellows disease in Romania
These results are first experimental proofs regarding the association of stolbur and aster yellows with grape yellows in Romania. Expand
