The TraR and TraI proteins of Agrobacterium tumefaciens mediate cell-density-dependent expression of the Ti plasmid tra regulon. TraI synthesizes the autoinducer pheromone N-(3-oxooctanoyl)-L-homoserine lactone (3-oxo-C8-HSL), while TraR is an 3-oxo-C8-HSL-responsive transcriptional activator. We have compared the abilities of 3-oxo-C8-HSL and

Conjugal transfer of Agrobacterium tumefaciens Ti plasmids is regulated by quorum sensing via TraR and its cognate autoinducer, N-(3-oxo-octanoyl)-L-homoserine lactone. We isolated four Tn5-induced mutants of A. tumefaciens C58 deficient in TraR-mediated activation of tra genes on pTiC58DeltaaccR. These mutations
