Comparative genomics of pAKD4, the prototype IncP-1delta plasmid with a complete backbone.

ABSTRACT: Plasmids of the incompatibility group IncP-1 are important agents of horizontal gene transfer and contribute to the spread of antibiotic resistance and xenobiotic degradation within bacterial communities. Even though some prototype plasmids have been studied in much detail, the diversity of this plasmid group was still greatly underestimated until recently, as only two of the five currently known divergent sub-groups had been described. To further improve our insight into the diversity and evolutionary history of this family of broad-host-range plasmids, we compared the complete nucleotide sequence of a new IncP-1delta plasmid pAKD4 to the genomes of other IncP-1 plasmids. Plasmid pAKD4 was previously isolated by exogenous plasmid isolation from an agricultural soil in Norway. Its 56,803bp
