European Strains Can Cause Symptoms in Blueberry.

Strains of the bacterial pathogen subspecies () and () isolated from symptomatic almond and olive plants in Spain and Italy were used in this study. Because of the risk of host jump and considering the importance of southern highbush blueberry production in Spain, we tested a small set of these strains for their potential to infect and cause disease symptoms in blueberries under greenhouse experiments. IVIA5901 (isolated from almonds in Alicante, Spain) caused symptoms similar to those caused by AlmaEm3 (isolated from blueberries in Georgia, U.

Two subsp. Strains Isolated from Almond in Spain Differ in Plasmid Content and Virulence Traits.

The plant-pathogenic bacterium is a major threat to agriculture and the environment worldwide. Recent devastating outbreaks in Europe highlight the potential of this pathogen to cause emergent diseases. subsp.

is a vascular plant pathogenic bacterium native to the Americas that is causing significant epidemics and economic losses in olive and almonds in Europe, where it is a quarantine pathogen. Since its first detection in 2013 in Italy, mandatory surveys across Europe revealed the presence of the bacterium also in France, Spain, and Portugal. Combining Oxford Nanopore Technologies and Illumina sequencing data, we assembled high-quality complete genomes of seven subsp.

Infection Reshapes Microbial Composition and Network Associations in the Xylem of Almond Trees.

represents a major threat to important crops worldwide including almond, citrus, grapevine, and olives. Nowadays, there are no efficient control measures for , and the use of preventive measures and host resistance represent the most practical disease management strategies. Research on vessel-associated microorganisms is gaining special interest as an innate natural defense of plants to cope against infection by xylem-inhabiting pathogens.

Divergent abiotic spectral pathways unravel pathogen stress signals across species.

Plant pathogens pose increasing threats to global food security, causing yield losses that exceed 30% in food-deficit regions. Xylella fastidiosa (Xf) represents the major transboundary plant pest and one of the world's most damaging pathogens in terms of socioeconomic impact. Spectral screening methods are critical to detect non-visual symptoms of early infection and prevent spread.

Detection of in almond orchards by synergic use of an epidemic spread model and remotely sensed plant traits.

The early detection of () infections is critical to the management of this dangerous plan pathogen across the world. Recent studies with remote sensing (RS) sensors at different scales have shown that -infected olive trees have distinct spectral features in the visible and infrared regions (VNIR). However, further work is needed to integrate remote sensing in the management of plant disease epidemics.

is an economically important plant pathogenic bacterium of global importance associated, since 2013, with a devastating epidemic in olive trees in Italy. Since then, several outbreaks of this pathogen have been reported in other European member countries including Spain, France, and Portugal. In Spain, the three major subspecies (subsp.

Emergence of a Plant Pathogen in Europe Associated with Multiple Intercontinental Introductions.

Pathogen introductions have led to numerous disease outbreaks in naive regions of the globe. The plant pathogen has been associated with various recent epidemics in Europe affecting agricultural crops, such as almond, grapevine, and olive, but also endemic species occurring in natural forest landscapes and ornamental plants. We compared whole-genome sequences of subspecies from America and strains associated with recent outbreaks in southern Europe to infer their likely origins and paths of introduction within and between the two continents.

Draft Genome Resources of Two Strains ("ESVL" and "IVIA5901") of Xylella fastidiosa Associated with Almond Leaf Scorch Disease in Alicante, Spain.

An outbreak of Xylella fastidiosa subsp. multiplex sequence type ST6 was discovered in 2017 in mainland Spain affecting almond trees. Two cultured almond strains, "ESVL" and "IVIA5901," were subjected to high throughput sequencing and the draft genomes assembled.

Draft Genome Sequence of Xylella fastidiosa subsp. Strain IVIA5235, Isolated from Prunus avium in Mallorca Island, Spain.

We report the complete annotated genome sequence of the plant-pathogenic bacterium Xylella fastidiosa subsp. strain IVIA5235. This strain was recovered from a cherry tree in Mallorca, Spain.
