Abstract

SUMMARY: Several plaque-forming phage P1 derivatives carrying DNA rearrangements associated with IS elements are described. They have IS, IS and IS inserted in four distinct locations, all of which are non-essential regions for phage P1 propagation. One derivative carries a genome segment, inverted relative to the one in the P1 wild-type genome, between two inverted copies of IS. The inverted DNA segment spans about 23 kb of the 90 kb long P1 genome and it includes the invertible C segment. This phage is as viable as an isomeric P1 which carries the relevant segment in its original orientation. These results are discussed with regard to the genome organization of phage P1.
