Draft Genome Sequence Resources of Three Strains (TOS4, TOS5, and TOS14) of Infecting Different Host Plants in the Newly Discovered Outbreak in Tuscany, Italy.

An outbreak of was discovered in late 2018 in northern Italy affecting several plant species. Multilocus sequence typing analyses detected the presence of strains clustering in subsp. and harboring a hitherto uncharacterized sequence type, ST87. Three cultured strains (TOS4, TOS5, and TOS14) were subjected to high-throughput sequencing and the draft genomes assembled. Phylogenetic analysis conclusively indicated that they belong to the subspecies . The genetic information generated for these newly discovered strains further supports the evidence that sequence types are associated with the emergence of in Europe, posing major challenges for predicting the main threatened European and Mediterranean crops and plant species.
