Plants under Siege: Investigating the Relevance of '. P. solani' Cixiid Vectors through a Multi-Test Study.

Crop losses caused by the plant pathogenic bacterium ' Phytoplasma solani' (CaPsol) underscore the need to better understand its perplexing epidemiological pathways. (Hemiptera, Cixiidae) is a prominent CaPsol vector with three plant associations in Serbia (/HobsUd; /HobsCa; /HobsCf). Another cixiid planthopper, (Dufour), has been recently confirmed as a noteworthy CaPsol vector.

Prevalence of a ' Phytoplasma solani'-Related Strain Designated as New 16SrXII-P Subgroup over ' Arsenophonus phytopathogenicus' in Sugar Beet in Eastern Germany.

Two phloem-limited pathogens, ' Arsenophonus phytopathogenicus' and ' Phytoplasma solani', threaten sugar beet production in France, Switzerland, and Germany. Previous studies of these pathogens in Germany had focused on its western and southern regions, leaving a knowledge gap about eastern Germany. Despite their importance, this study is the first to investigate phytoplasmas in sugar beet in Saxony-Anhalt, Germany.

A biotroph sets the stage for a necrotroph to play: ' Phytoplasma solani' infection of sugar beet facilitated root rot.

' Phytoplasma solani' (stolbur phytoplasma) is associated with rubbery taproot disease (RTD) of sugar beet ( L.), while is considered the most important root rot pathogen of this plant in Serbia. The high prevalence of .

Epidemiological role of novel and already known 'Ca. P. solani' cixiid vectors in rubbery taproot disease of sugar beet in Serbia.

Rubbery taproot disease (RTD) of sugar beet was recently associated with the plant pathogenic bacterium 'Candidatus Phytoplasma solani' (CaPsol) and reported throughout the Pannonian Plain with variations in severity. Tracing CaPsol epidemiological pathways was performed in the experimental sugar beet field in Rimski Šančevi (Serbia) in 2020-2021, where an RTD outbreak was recently recorded. A molecular epidemiology approach was applied to the study of three RTD occurrence scenarios: epidemic, non-epidemic and 'absence of RTD'.

Multilocus Genotyping of ' Phytoplasma solani' Associated with Rubbery Taproot Disease of Sugar Beet in the Pannonian Plain.

Rubbery taproot disease of sugar beet (RTD), associated with ' Phytoplasma solani', appeared in 2020 on an epidemic scale in northern Serbia and southern Slovakia, situated at opposite edges of the Pannonian Plain. In the affected locations where the disease was assessed, symptomatic sugar beets were analysed for phytoplasma infection. Additionally, multilocus sequence analyses of '.

Rubbery Taproot Disease of Sugar Beet in Serbia Associated with ' Phytoplasma solani'.

Rubbery taproot disease (RTD) of sugar beet was observed in Serbia for the first time in the 1960s. The disease was already described in neighboring Bulgaria and Romania at the time but it was associated with abiotic factors. In this study on RTD of sugar beet in its main growing area of Serbia, we provide evidence of the association between ' Phytoplasma solani' (stolbur phytoplasma) infection and the occurrence of typical RTD symptomatology.

Occurrence and Identification of subsp. and Causing Blackleg in Some Potato Fields in Serbia.

Blackleg outbreaks were noticed on three fields (about 100 ha total) in 2 consecutive years (2018, 2019) in one of the main potato growing areas in Serbia (Bačka region, Vojvodina). The percentage of infected plants reached 40 to 70%, with 10.5 to 44.

Widespread plant specialization in the polyphagous planthopper Hyalesthes obsoletus (Cixiidae), a major vector of stolbur phytoplasma: Evidence of cryptic speciation.

The stolbur phytoplasma vector Hyalesthes obsoletus is generally considered as a polyphagous species associated with numerous wild and cultivated plants. However, recent research in southeastern Europe, the distribution centre of H. obsoletus and the area of most stolbur-inflicted crop diseases, points toward specific host-plant associations of the vector, indicating specific vector-based transmission routes.

Morphology versus DNA barcoding: two sides of the same coin. A case study of Ceutorhynchus erysimi and C. contractus identification.

Genotyping of 2 well-known weevil species from the genus Ceutorhynchus (Coleoptera: Curculionidae) distributed in west Palearctic, C. erysimi and C. contractus, revealed phenotype versus genotype inconsistencies in a set of 56 specimens (25 C.
