Cloning of phzIR from the endophytic Pseudomonas sp. G5 and its expression in Escherichia coli
内生菌Pseudomonas sp. G5 phzIR基因的克隆与表达

We isolated a new strain of endophytic Pseudomonas G5 from the stems of Chinese parsley(Coriandrum sativum L.),and it is tentatively identified as Pseudomonas aurantiaca according to analysis of the entire substrate utilization profiles using BIOLOG MicrostationTM system(BIOLOG,Inc,Hayward CA).An array of evidence established that many Gram-negative bacteria employ Quorum sensing(QS) system to regulate gene expression in response to cell density using small diffusible signal molecules,N-acyl homoserine lact...
