Genomic Analysis of Prophage Distribution in Xylella fastidiosa Reveals Extensive Diversity and Horizontal Gene Transfer
Xylella fastidiosa is a plant-pathogenic bacterium responsible for significant agricultural and environmental impact. Prophages, genetic elements of viral origin integrated into bacterial genomes, play a key role in bacterial evolution by facilitating horizontal gene...
A genomic locus uniquely encoded by blueberry-infecting Xylella fastidiosa strains affects motility and biofilm formation in vitro, and virulence in planta
Xylella fastidiosa (Xf) is an insect-transmitted, xylem-limited bacterial plant pathogen that infects hundreds of plant species. This pathogen causes bacterial leaf scorch in southern highbush blueberry (Vaccinium corymbosum interspecific hybrids) in the southeastern...
First Report of Xylella fastidiosa Infection and Pierce’s Disease in Resistant Grape Cultivars in Texas, United States
All commercially cultivated European grapevines (Vitis vinifera) are considered susceptible to Pierces disease (PD) caused by the xylem-limited bacterium Xylella fastidiosa (Wilcox et al. 2015). PD causes vine losses and is the primary limiting factor to grape...
Complete Genome Sequence Data of Two Xylella fastidiosa subsp. multiplex Strains (ST26) Isolated from Infected Almond and Cherry in Southern Italy
In the framework of the monitoring campaign annually carried out in the Apulia region (southern Italy) to tackle the epidemic of X. fastidiosa subsp. pauca decimating olive trees, an outbreak of Xylella fastidiosa subsp. multiplex was discovered in 2024 with almond...
Diversity and lytic potential of novel phages targeting Xylella fastidiosa subsp. fastidiosa
Xylella fastidiosa is a xylem-limited plant-pathogenic bacterium responsible for several economically significant plant diseases, including Pierce’s disease in grapevine. Current control strategies face significant challenges in completely eradicating this pathogen....
Isolation, Phylogenetic Inferences, and Early Diversification of Xylella fastidiosa subsp. fastidiosa in Cova da Beira Region, Portugal
The introduction of Xylella fastidiosa, a plant pathogen with a broad host range, poses a significant threat to agriculture and natural ecosystems. We analyzed six X. fastidiosa subsp. fastidiosa strains obtained from the Beira Interior region of Portugal, an area...
A pathogen of good taste: genetics of a bacterial host jump of the plant pathogen Xylella fastidiosa from coffee to wine grapes
When pathogens are repeatedly introduced into new environments, host jumps may occur into naïve taxa. Given the magnitude of the global plant trade, this process can lead to frequent disease emergence as interactions between previously isolated pathogens and new plant...
