Abstract excerpt
An Escherichia coli mutant, ts121, was isolated following random insertional mutagenesis using phage lambda Mu transposition. The mutant phenotype includes inability to form colonies at temperatures above 38 degrees C and inability to propagate phage lambda at all temperatures. A lambda i434 cI- (ts121)+ transducing phage was isolated on the basis of its ability to form plaques on ts121 mutant bacteria. Using...
