Abstract
We developed a generic method for high-throughput cloning in bacteria that are less amenable to conventional DNA manipulations. The method involves ligation-independent cloning in an intermediary Escherichia coli vector, which is rapidly converted via vector-backbone exchange (VBEx) into an organism-specific plasmid ready for high-efficiency transformation. We demonstrated VBEx proof of principle for Lactococcus lactis, but the method can be adapted to all organisms for which plasmids are available.
