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

Citation

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.

Acquisition and Transmission of ‘Candidatus Liberibacter solanacearum’ Differs Among Wolbachia-Infected and -Uninfected Haplotypes of Bactericera cockerelli

“Liberibacter solanacearum”
Abstract
‘Candidatus Liberibacter solanacearum’ (Lso) causes disease symptoms and economic losses in potato, tomato, and other solanaceous crops in North America. Lso is transmitted to plants by the potato psyllid, Bactericera cockerelli, which occurs as distinct haplotypes named western, central, and northwestern that differ in the presence or absence of the bacterial endosymbiont, Wolbachia. Previous work showed that all three vector haplotypes can transmit Lso, but it was not clear whether acquisitio

Development of a Loop-Mediated Isothermal Amplification (LAMP) Method to Detect the Potato Zebra Chip Pathogen ‘Candidatus Liberibacter solanacearum’ (Lso) and Differentiate Haplotypes A and B

Abstract
‘Candidatus Liberibacter solanacearum’ (Lso) is the causal agent of zebra chip of potato (Solanum tuberosum), which can significantly reduce potato yield. In this study, a loop-mediated isothermal amplification (LAMP) method for the detection of Lso haplotypes A and B was developed and evaluated. Two sets of LAMP primers named LAMP-A and LAMP-B were designed and tested for specificity and sensitivity. Both LAMP-A and LAMP-B were specific to Lso in in silico analysis using the Primer-Blast tool.

Growth and Yield Performance of Solanum tuberosum Grown from Seed Potatoes Infected with ‘Candidatus Liberibacter solanacearum’ Haplotypes A and B

“Liberibacter solanacearum”
Abstract
Zebra chip (ZC) disease of potato (Solanum tuberosum) is associated with infection by ‘Candidatus Liberibacter solanacearum’ (Lso). Two haplotypes of Lso—A and B—occur in the United States. Lso haplotype B is more virulent than haplotype A, causing greater disease incidence in tubers, more severe symptoms, and greater loss in tuber yield. This study assessed whether tubers from infected plants generate new infected plants the following year. The effects of both Lso haplotypes A and B on tuber r
