title: Deinococcus radiodurans DNA increases the radiation resistance of Escherichia coli.
abstract: A genomic DNA library of Deinococcus radiodurans DNA has been prepared using the plasmid vector pBR322. The recombinant plasmid was used to transform a more radiation-sensitive organism, Escherichia coli RR1. Following selection of transformed organisms by their ability to grow on ampicillin, radiation-resistant organisms were selected by irradiation with 137Cs gamma radiation. Increased radiation resistance correlates with the presence of a 3-kb fragment of DNA in these cells which is derived from D. radiodurans.
