Physalis virginiana as a Wild Field Host of Bactericera cockerelli (Hemiptera: Triozidae) and ‘Candidatus Liberibacter solanacearum’

Citation

Names
“Liberibacter solanacearum”
Abstract
The potato/tomato psyllid, Bactericera cockerelli (Šulc), is among the most important pests of solanaceous crops as a vector of the pathogen ‘Candidatus Liberibacter solanacearum’ (Lso). Lso-infected psyllids often arrive in crop fields from various wild species of Solanaceae and Convolvulaceae, especially those that provide early-season hosts for the vector. Physalis species are perennial plants within the family Solanaceae with often broad geographical distributions that overlap those of B. c

Molecular characterization of ‘Candidatus Phytoplasma phoenicium’ infecting almond (Prunus dulcis) and evaluation of biochemical defenses produced in the plants

Names
Ca. Phytoplasma phoenicium
Abstract
AbstractIncreasing incidences of phytoplasma infestations in Almond trees warrants the better management approach to prevent yield losses. Disease management rely on identification of the pathogen based on molecular profiling. The present study aimed, to identify the phytoplasma agent in almond trees and to measure the biochemical responses it causes in the host. Direct and Nested PCRs performed using phytoplasma specific primer pairs 16S rRNA, detected the presence of phytoplasma agent in sympt

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

Citation
Duduk et al. (2023). Plant Disease 107 (12)
Names
Ca. Arsenophonus phytopathogenicus Ca. Phytoplasma solani
Abstract
Two phloem-limited pathogens, ‘Candidatus Arsenophonus phytopathogenicus’ and ‘Candidatus 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 phytoplasma strain related to ‘Ca. P. solani’ is found p

New Assays for Rapid Detection of Beet Leafhopper-Associated Plant Pathogens, ‘Candidatus Phytoplasma trifolii’, Beet Curly Top Virus, and Spiroplasma citri

Citation
Swisher Grimm et al. (2023). Plant Disease 107 (12)
Names
Ca. Phytoplasma trifolii
Abstract
The beet leafhopper Circulifer tenellus is an important pest of agricultural crops in the United States, where it transmits beet curly top virus, beet leafhopper-transmitted virescence agent phytoplasma, and Spiroplasma citri to numerous crops, affecting yield and quality. Each of these pathogens have been linked to serious disease outbreaks within Washington State in the past century. To mitigate the risk of disease, growers target the beet leafhopper in their insect pest management programs.
