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...
A survey in natural olive resources exposed to high inoculum pressure indicates the presence of traits of resistance to Xylella fastidiosa in Leccino offspring
The epidemic spread of the harmful bacterium Xylella fastidiosa causing the “olive quick decline syndrome”, decimating olive trees in southern Italy, in the region of Apulia, prompted investigations to search for olive genotypes harbouring traits of resistance.
New Approaches to Plant Pathogen Detection and Disease Diagnosis
Detecting plant pathogens and diagnosing diseases are critical components of successful pest management. These key areas have undergone significant advancements driven by breakthroughs in molecular biology and remote sensing technologies within the realm of precision...
An integrated strategy for pathogen surveillance unveiled Xylella fastidiosa ST1 outbreak in hidden agricultural compartments in the Apulia region (Southern Italy)
Annual surveillance programs for the plant pathogenic bacterium Xylella fastidiosa are implemented in Europe as part of the preventive phytosanitary strategies enforced to face the emergence of the detrimental infections reported in olives in southern Italy. The...
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...
