Table 1 Summary of the integron distribution in the collection of 73,655 all currently available bacteria whole (complete and draft) genomes identified by I-VIP developed in this study. All sequences in bacteria whole (complete and draft) genomes were annotated into chromosomes and plasmids by NCBI GenBank annotation and curated by PlasFlow. The chromosomes/plasmids of complete genomes annotated by PlasFlow were compared to the GenBank annotation, as indicated in the brackets
