摘要

Objective

Peach bacterial spot, caused by Xanthomonas arboricola pv. pruni (Xap), poses a significant threat to the global peach industry. Studies have indicated that 41 Xap strains isolated from various peach cultivars in China exhibit moderate genetic differentiation, clear specificity to peach cultivars, and limited geographical differentiation. The genomic information of 36 Xap strains isolated from different countries has been deposited to the NCBI genome database; However, complete genome sequences for Xap strains identified in China remain lacking. In this study, the whole genome of the Xap 9-4 strain, isolated from diseased peach leaves in China, was assembled and annotated.

Data description

The genomic data of the Xap 9-4 strain was sequenced using the Illumina and PacBio platforms. The whole genome of Xap 9-4 consisted of a 5,174,371 bp circular chromosome and a 41,329 bp circular plasmid, encoding 4,660 protein-coding genes, 201 ncRNAs, 643 repeat regions and 7 prophages. Approximately 94.82% of the proteins were annotated. Phylogenic analysis revealed minimal genetic variation among Xap strains isolated from different countries. These findings will expand the genomic resources for Xap and provide a foundation for further studies on genetic diversity and pathogen-host interaction mechanisms.
