Xylella fastidiosa subsp. multiplex strain:Alm_Lz_1 Genome sequencing and assembly. Xylella fastidiosa subsp. multiplex strain:Alm_Lz_1

A novel isolate (Alm_Lz_1) of X. fastidiosa was isolated from an almond tree in a new outbreak of Xylella fastidiosa emerged in late 2021 in the Italian region of Lazio. From multilocus sequence type analysis (MLST) Alm-Lz-1 had the same ST of the bacterial isolates recovered in the outbreak discovered in late 2018, in the neighbor region of Tuscany (approx. 30-50 km apart). In both outbreaks, bacterial isolates were found to harbor the ST87 and to be genetically related to strains of the subspecies multiplex. Whole genome sequencing and assembly of the strain Alm-Lz-1 cultured from an infected almond tree sampled in the outbreak was obtained to perform comparative genomic studies aiming at defining the relatedness of this new outbreak with those previously reported from Italy and worldwide, contributing to understanding the pathway of introduction and the host plants under risk in the outbreak area.
