Abstract
SUMMARY: Transfer of citrate utilization (Cit+) was achieved with a plasmid (pCIT354) which is Fi+, has F-like pili and fails to inhibit phage propagation. Transduction of Cit+ was achieved with P1 phage. Results of incompatibility tests with R plasmids indicated that pCIT354 is a self-repressed F-like plasmid.
