Evidence for the widespread production of DSF family signal molecules by members of the genus Burkholderia by the aid of novel biosensors.

许多细菌利用顺式-2-不饱和脂肪酸，即 DSF（可扩散信号因子）家族信号分子，进行种内和种间通讯，调控生物膜形成、运动性、水解酶产生及毒力因子表达。本研究基于 Burkholderia cenocepacia H111 中 BDSF（伯克霍尔德菌可扩散信号因子）依赖的群体感应回路组件，构建了新型 luxAB 生物发光和 GFP 荧光...
