The integration of autonomous transmissible plasmids into the chromosome ofEscherichia coliK12

Abstract
SUMMARY: The highly selective technique of integrative suppression has been used to determine the ability of autonomous transmissible plasmids to integrate into theE. colichromosome.All theF-like transmissible plasmids appear to be able to integrate, suppress the initiation defect and formHfr-type donor strains. However, there is no evidence of integration with theI-like transmissible plasmids examined.
