Abstract

Abstract pIH1972 is a 23.6-Mdal lac + plasmid derived from P1 dlw. This plasmid is stably maintained and it exhibits absolute incompatibility with P1 in RecA bacteria. A cluster of P1- EcoRI DNA fragments 15, 17, 18, 21, and 23 and part of fragments 14 and 5 are identified in the PI DNA region carried by pIH1972. It is suggested that P1 compatibility and plasmid maintenance genes are carried on the identified 10% segment of the P1 genome.
