A broad-host-range in vivo pop-out and amplification system for generating large quantities of 50-to 100-kb genomic fragments for direct DNA sequencing

A prerequisite for sequencing large genomes is to obtain 30- to 150-kb genomic DNA fragments in adequate quantity. Previously, we developed a system which enables one to excise and amplify in vivo such segments directly from the Escherichia coli genome. This system, which employed the yeast Flp/FRTelements for excision and the plasmid R6K-based replication machinery for DNA amplification, permits one to bypass conventional cloning [Pósfai et al....
