摘要

Vibrio species are recognized as potential causative agents of coral diseases, yet their metabolic capabilities concerning different nitrogen sources, such as urea, have been largely understudied. This study focuses on 18 urea-utilizing Vibrio strains isolated from coral, for which we performed complete genome sequencing using Illumina technology. The average assembled genome size was 5.67 Mb, with an average contig N50 of 0.61 Mb and scaffold N50 of 0.61 Mb. We predicted an average of 5,087 protein-coding genes per genome, with over 95% of these genes successfully annotated for function. Benchmarking Universal Single-Copy Orthologs (BUSCO) analysis revealed an average 98.9% completeness for the Vibrio spp. lineage. Overall, this study provides high-quality genomic data for these Vibrio strains, offering a valuable resource for further research into their evolution, molecular mechanisms of pathogenicity, and their specific roles in the nitrogen cycle of the coral ecosystem.
