Abstract:
We have generated a genomic P1 bacteriophage library using Monterey pine (Pinus radiata) DNA. We first developed a method for isolating from pine tissue the very high molecular weight DNA necessary for the preparation of libraries requiring large inserts. The method involves protoplasting the cells, isolating nuclei and lysis in a high concentration of detergent. Fragments of greater than two megabases in size are produced in solution. Modifications introduced to the protocol for library preparation and for P1 plasmid isolation are described.
