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.
在具有产气克雷伯菌染色体hut基因和鼠伤寒沙门氏菌附加体hut基因的产气克雷伯菌部分二倍体菌株中,任一物种的阻遏物都可以调控另一物种的hut操纵子。在这两种生物体中,同源阻遏物对左侧hut操纵子施加的阻遏作用都强于异源阻遏物所施加的阻遏作用。
