The phage hybrid phi80hy43 derived from a vegetative cross phi80cIhlambda x lambdacIc17 was constructed for discrimination phi80mono- and polylysogens. Molecular structure of this hybrid was established using heteroduplex analysis and restriction endonuclease EcoRI. It is found that the hybrid phi80hy43 represents a phage phi80 containing a foreign piece of DNA between genes cI and 0. The length of this piece of DNA comprises 0.7%, corresponding to the length of cy-cII region of th phage lambda. So it is believed that the hybrid phi80hy43 was formed due to insertion of the lambdacy region with the mutation c17 into phi80hlambda phage genome.
