Abstract

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 is considered a quarantine pathogen. Since its first detection in 2013 in Italy, mandatory surveys to search for Xf across Europe revealed the presence of three Xf subspecies (fastidiosa, multiplex and pauca) in different outbreaks occurring in France, Spain, and Portugal. Xf subspecies sandyi and morus have not been associated to epidemic outbreaks in Europe; however, subspecies sandyi has been detected in intercepted plants imported from Costa Rica and Honduras. By combining data from the Oxford Nanopore Technologies and Illumina sequencing platforms, we obtained complete genomes for Xf strains CO33 and CFBP8478. Both strains belong to the subspecies sandyi and were isolated from coffee plants intercepted in Europe that were imported from Costa Rica. These two genome resources increase the scarce number of Xf genomes available belonging to the subspecies sandyi which is crucial for comparative genomic analysis and population studies of this important plant pathogenic bacterium.

Background Olive is one of the most cultivated species in the Mediterranean Basin and beyond. Despite being extensively studied for its commercial relevance, the origin of cultivated olive and the history of its domestication remain open questions. Here, we present a...
