Findings show the Extremadura outbreak stems from a virulent ST1 lineage closely related to American populations, underscoring the need for reinforced genomic surveillance in Europe.

Pathogenicity tests confirmed systemic infection and symptom development. Also phage susceptibility suggests potential for biocontrol.

Comparative genomics showed strong core-genome conservation and similar prophage repertoires, pointing to a recent introduction with limited local diversification. All Iberian isolates displayed chromosomal integration of plasmid 🧬 pXFSL21, the first documented case in Xff 🆕

A new outbreak of Xylella fastidiosa (Xff) has emerged in Extremadura, Spain in 2024. PCR, MLST, and whole genome sequencing revealed the exclusive presence of lineage Xff-ST1 in wild hosts and the vector Philaenus spumarius

The Bacteriology, Virology, and Mycology groups of @GVAivia took part in the 6th Meeting of the GEDDI Group-@SEFitopatologia, presenting 10 studies that showcase the strength and diversity of our research in plant health.
An inspiring experience!
