Escherichia coli leu(+) episomes were transferred to Salmonella typhimurium. The levels of two leucine-forming enzymes were normal (low) in the resulting merodiploids, suggesting that the putative Samonella leucine repressor recognizes the Escherichia leucine operator.
大肠杆菌亮氨酸(+)附加体被转移到鼠伤寒沙门氏菌中。在产生的部分二倍体中,两种亮氨酸合成酶的水平正常(低),这表明推测的沙门氏菌亮氨酸阻遏物识别大肠杆菌亮氨酸操纵基因。
