摘要:
DNA from a temperate phage ρ{variant}11 and chromosomal DNA of Bacillus subtilis 168 were digested with endonuclease EcoRI and then ligated with T4 polynucleotide ligase. The ligated DNA fragments were used to transform a lysogenic strain, B. subtilis spoA12 lys21 hisA1 leuA8 ρ{variant}11, and Lys+, His+ or Leu+ transformants were selected. The cells of each type were then mixed, grown and treated with mitomycin C; the induced phages were tested for abilities abilities to form plaques and to transduce the auxotrophic marker. Various types of plaque-forming or defective phages which transduce hisA or lys marker at considerably high frequencies were thus obtained. © 1979.
