I + × I + crosses were studied, using various Coll plasmids. Exclusion due to presence of Coll in recipients was removed by starvation, with production of I – phenocopies. Superinfection immunity prevented normal replication of transferred genes: thus, Itrp + donated to an I + trp– recipient led to formation of abortive recombinants.
