Salmonella typhimurium but not citrate-utilizing Escherichia coli carrying the Cit plasmid showed positive chemotaxis to tricarboxylic acids, indicating that the Cit plasmid encodes a transport system but not a chemoreceptor for citrate.
携带Cit质粒的鼠伤寒沙门氏菌对三羧酸呈阳性趋化性,但利用柠檬酸盐的大肠杆菌则不然,这表明Cit质粒编码一种转运系统,而非柠檬酸盐的化学感受器。
