The complete genome of “ Candidatus Phytoplasma fraxini” AshY1 from the ash yellows group

Citation
Böhm et al. (2024). Microbiology Resource Announcements 13 (7)
Names
Ca. Phytoplasma fraxini
Abstract
ABSTRACT The complete genome of “ Candidatus Phytoplasma fraxini” AshY1, originating from Fraxinus americana in North America, was assembled using long reads from single-molecule real-time sequencing technology. The chromosome of 598 kb provides insights into the effector repertoire of a phytopathogenic bacterium from the 16SrVII phytoplasma group.

Pentastiridius leporinus (Linnaeus, 1761) as a Vector of Phloem-Restricted Pathogens on Potatoes: ‘Candidatus Arsenophonus Phytopathogenicus’ and ‘Candidatus Phytoplasma Solani’

Names
Arsenophonus Ca. Arsenophonus phytopathogenicus Ca. Phytoplasma Ca. Phytoplasma solani
Abstract
In Germany, the phloem-sucking planthopper Pentastiridius leporinus (Hemiptera: Cixiidae) currently represents the epidemiological driver for the spread of the syndrome “Basses Richesses” in sugar beets, which results in a reduced sugar content and an economic loss for the farmers. This disease is associated with the γ-proteobacterium ‘Candidatus Arsenophonus phytopathogenicus’ and the Stolbur phytoplasma ‘Candidatus Phytoplasma solani’. Recently, P. leporinus was found in potato fields in Germa

Genome Comparison of ‘Candidatus Phytoplasma rubi’ with Genomes of Other 16SrV Phytoplasmas Highlights Special Group Features

Citation

Names
Ca. Phytoplasma rubi Ca. Phytoplasma ziziphi
Abstract
Phytoplasmas are associated with important bacterial diseases, causing severe symptoms in agricultural and ornamental crops. ‘Candidatus Phytoplasma rubi’, associated with the Rubus stunt in raspberries (Rubus idaeus) and blackberries (Rubus subgenus Rubus), causes shortened internodes, elongated sepals, proliferation, phyllody, and virescence. The recently published genome of ‘Ca. P. rubi’ RS enabled a comprehensive genomic comparison to the complete genomes of 16SrV phytoplasmas, comprising st

Complete Genome of “ Candidatus Phytoplasma rubi” RS, a Phytopathogenic Bacterium Associated with Rubus Stunt Disease

Citation
Duckeck et al. (2023). Microbiology Resource Announcements 12 (5)
Names
Ca. Phytoplasma rubi
Abstract
The phytoplasma “ Candidatus Phytoplasma rubi” is associated with Rubus stunt disease. The complete genome was determined by assembling Oxford Nanopore Technologies system-derived long reads, with short-read polishing with Illumina reads. The genome of strain RS, from Germany, is organized in one circular chromosome with a length of 762 kb.

Revision of the ‘Candidatus Phytoplasma’ species description guidelines

Citation
Bertaccini et al. (2022). International Journal of Systematic and Evolutionary Microbiology 72 (4)
Names
Ca. Phytoplasma
Abstract
The genus ‘Candidatus Phytoplasma’ was proposed to accommodate cell wall-less bacteria that are molecularly and biochemically incompletely characterized, and colonize plant phloem and insect vector tissues. This provisional classification is highly relevant due to its application in epidemiological and ecological studies, mainly aimed at keeping the severe phytoplasma plant diseases under control worldwide. Given the increasing discovery of molecular diversity within the genus ‘Ca. Phytoplasma’,

Widespread occurrence of ‘Candidatus Phytoplasma ulmi’ in elm species in Germany

Abstract
Abstract Background ‘Candidatus Phytoplasma ulmi’ is the agent associated with elm yellows and has been categorised in the European Union as a quarantine pathogen. For central and northern European countries, information on the occurrence and distribution of the pathogen and its impact on elms is scarce, so a survey of native elm trees has been conducted in Germany. Results About 6500 samples from Ulmus minor, Ulmus l

Abstract
Abstract Background: Candidatus Phytoplasma ulmi' is the agent associated with elm yellows and has been categorised in the European Union as a quarantine pathogen. For central and northern European countries, information on the occurrence and distribution of the pathogen and its impact on elms is scarce, so a survey of native elm trees has been conducted in Germany. Results: About 6,500 samples from Ulmus minor , Ulmus laevis and Ulmus glabra , were collected nationwide. Phytoplasma dete
