In recent years, the bacterium Xylella fastidiosa has been spreading in almond orchards (causing almond leaf scorch) and in grapevines (causing Pierce's disease) in northern Israel. Sucking insects specialized for xylem sap-feeding transmit this plant...

Phylogenomic analysis of Xylella fastidiosa subsp. pauca strains from olive and almond trees in Argentina
Xylella fastidiosa (Xf) is a Gram-negative bacterium that significantly threatens agricultural crops worldwide. In Argentina, severe symptoms resembling those of olive quick decline syndrome (OQDS) in Italy have been observed in Xf-infected olive orchards, primarily...
Multiple genotypes of a quarantine plant pathogen detected in New Zealand indigenous plants located in a botanical garden overseas
Xylella fastidiosa is a xylem-limited bacterial plant pathogen transmitted by insect vectors. It infects a wide range of plant species and causes devastating diseases. Botanical gardens are global repositories of plant diversity exposed to local biotic and abiotic...
Linking intercontinental biogeographic events to decipher how European vineyards escaped Pierce’s disease
Global change is believed to be a major driver of the emergence of invasive pathogens. Yet, there are few documented examples that illustrate the processes that hinder or trigger their geographic spread. Here, we present phylogenetic, epidemiological and historical...
European Xylella fastidiosa strains can cause symptoms in blueberry
Strains of the bacterial pathogen Xylella fastidiosa subspecies multiplex (Xfm) and pauca (Xfp) isolated from symptomatic almond and olive plants in Spain and Italy were used in this study. Due to the risk of host jump and considering the importance of southern...
Species composition and prevalence of sharpshooters and spittlebugs potential vectors of Xylella fastidiosa in olive orchards of southeastern Brazil
Xylem sap-feeding auchenorrhynchans, e.g. sharpshooters and spittlebugs (Hemiptera: Cicadellinae and Cercopoidea, respectively), are considered potential vectors of the xylem-limited bacterium Xylella fastidiosa, which is associated with olive leaf desiccation...
Performance of outbreak management plans for emerging plant diseases: the case of almond leaf scorch caused by Xylella fastidiosa in mainland Spain
Outbreak response to quarantine pathogens and pests in the European Union (EU) is regulated by the EU Plant Health Law, but the performance of outbreak management plans in terms of their effectiveness and efficiency has been quantified only to a limited extent. As a...
Seasonal Dynamics and Distribution of Xylella fastidiosa in Infected Almond Trees
Xylella fastidiosa (Xf) is a quarantine plant pathogen in the European Union, recognized as a high-priority pest due to its devastating cultural and economic impact on crops, ornamental plants, and landscape vegetation. The development and implementation of reliable,...
