Abstract

In merodiploid strains of Klebsiella aerogenes with chromosomal hut genes of K. aerogenes and episomal hut genes of Salmonella typhimurium, the repressor of either species can regulate the hut operons of the other species. The repression exerted by the homologous repressor on the left-hand hut operon is, in both organisms, stronger than that exerted by the heterologous repressor.
