Analysis of transfer frequencies using a transfer-constitutive mutant of pTiC58 showed that quorum sensing requires both the opine induction and autoinduction systems. Analysis of lacZ fusions determined that quorum-sensing results from TraR and AAI activating transfer gene expression only at high cell densities. The bacteria measure their density by sensing the concentration of AAI in the growth medium. Made available in DSpace on 2015-09-28T15:17:49Z (GMT).
