Abstract 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 world’s most damaging terms socioeconomic impact. Spectral screening methods are critical detect non-visual symptoms early infection prevent spread. However, subtle pathogen-induced physiological alterations spectrally detectable entangled with dynamics abiotic stresses. Here,...
Pathogen introductions have led to numerous disease outbreaks in naive regions of the globe. The plant pathogen
The early detection of Xylella fastidiosa (Xf) infections is critical to the management this dangerous plan pathogen across world. Recent studies with remote sensing (RS) sensors at different scales have shown that Xf-infected olive trees distinct spectral features in visible and infrared regions (VNIR). However, further work needed integrate plant disease epidemics. Here, we research how changes picked up by sets RS traits (i.e., pigments, structural or leaf protein content), can help...
Xylella fastidiosa (Xf) is a quarantine plant pathogen in the European Union, recognized as high-priority pest due to its devastating cultural and economic impact on crops, ornamental plants, landscape vegetation. The development implementation of reliable, sensitive, specific diagnostic methods for Xf detection are critical ensure production trade healthy material facilitate effective control measures, primarily aimed at eradication. Despite availability numerous protocols, their parameters...
The bacterium Xylella fastidiosa (Xf) is a plant pathogen that can block the flow of water and nutrients through xylem. Xf symptoms may be confounded with generic stress responses. Here, we assessed changes in biochemical, biophysical photosynthetic traits, inferred using models, Xf-affected almond orchards under rainfed irrigated conditions on Island Majorca (Balearic Islands, Spain). Recent research has demonstrated early detection Xf-infections by monitoring spectral associated pigments,...
Xylella fastidiosa represents a major threat to important crops worldwide including almond, citrus, grapevine, and olives. Nowadays, there are no efficient control measures for X. fastidiosa, the use of preventive host resistance represent most practical disease management strategies. Research on vessel-associated microorganisms is gaining special interest as an innate natural defense plants cope against infection by xylem-inhabiting pathogens. The objective this research has been...
An outbreak of Xylella fastidiosa subsp. multiplex sequence type ST6 was discovered in 2017 mainland Spain affecting almond trees. Two cultured strains, "ESVL" and "IVIA5901," were subjected to high throughput sequencing the draft genomes assembled. Phylogenetic analysis conclusively indicated they belong subspecies multiplex, pairwise comparisons chromosomal showed an average nucleotide identity higher than 99%. Interestingly, two strains differ for presence plasmids pXF64-Hb_ESVL...
The plant-pathogenic bacterium Xylella fastidiosa is a major threat to agriculture and the environment worldwide. Recent devastating outbreaks in Europe highlight potential of this pathogen cause emergent diseases. X. subsp. multiplex ESVL IVIA5901 strains that belong sequence type 6 were isolated from almond orchards within outbreak area Alicante province (Spain). Both share more than 99% chromosomal sequences (average nucleotide identity), but strain harbors two plasmids (pXF64-Hb_ESVL...
We report the complete annotated genome sequence of plant-pathogenic bacterium Xylella fastidiosa subsp. strain IVIA5235. This was recovered from a cherry tree in Mallorca, Spain.
Xylella fastidiosa is an economically important plant pathogenic bacterium of global importance associated, since 2013, with a devastating epidemic in olive trees Italy. Since then, several outbreaks this pathogen have been reported other European member countries including Spain, France, and Portugal. In the three major subspecies (subsp. fastidiosa, multiplex, pauca) detected Balearic Islands, but only multiplex mainland (Alicante). We present first complete genome sequences two Spanish...
Xylella fastidiosa is a vascular plant pathogenic bacterium native to the Americas that causing significant epidemics and economic losses in olive almonds Europe, where it quarantine pathogen. Since its first detection 2013 Italy, mandatory surveys across Europe revealed presence of also France, Spain, Portugal. Combining Oxford Nanopore Technologies Illumina sequencing data, we assembled high-quality complete genomes seven X. subsp. strains isolated from different plants United States,...
Xylella fastidiosa ( Xf) is a vascular phytopathogenic bacterium native to the Americas, known for causing severe diseases and significant economic losses in important crops. In Europe, Xf considered quarantine pathogen. Since its first detection 2013 Italy, mandatory surveys search across Europe have revealed presence of three subspecies fastidiosa, multiplex, pauca) different outbreaks occurring France, Spain, Portugal. sandyi morus not been associated with epidemic Europe; however, has...
Strains of the bacterial pathogen Xylella fastidiosa subspecies multiplex (Xfm) and pauca (Xfp) isolated from symptomatic almond olive plants in Spain Italy were used this study. Because risk host jump considering importance southern highbush blueberry production Spain, we tested a small set these strains for their potential to infect cause disease symptoms blueberries under greenhouse experiments. Xfm IVIA5901 (isolated almonds Alicante, Spain) caused similar those by AlmaEm3 Georgia,...
