title: Genetic evidence for subunits in the fertility repressor produced by F-like R factors.
abstract: Repressor-negative mutants derived from R 100 were tested for genetic complementation. The results indicate that the active repressor is a multimer. The properties of an unusual repressor mutant are also discussed.
