A LuxR-LuxI type regulatory system activates Agrobacterium Ti plasmid conjugal transfer in the presence of a plant tumor metabolite
Open accessAbstract
Conjugal transfer of Agrobacterium octopine-type Ti plasmids is activated by octopine, a metabolite released from plant tumors. Octopine causes conjugal donors to secrete a pheromone, Agrobacterium autoinducer (AAI), and exogenous AAI further stimulates conjugation. The putative AAI synthase and an AAI-responsive transcriptional regulator were found to be encoded by the Ti plasmid traI and traR genes, respectively, and the expression of traR was induced by octopine. The octopine-type traR gene product is highly homologous to the TraR protein recently characterized from a nopaline-type Ti plasmid. TraR and TraI are homologous to the LuxR and LuxI regulatory proteins of Vibrio fischeri, and AAI is similar in structure to the diffusable V. fischeri autoinducer, the inducing ligand of LuxR. TraR activated target genes in the presence of AAI and also activated traR and traI themselves, creating two positive-feedback loops. TraR-AAI-mediated activation in wild-type Agrobacterium strains was dramatically enhanced by culturing on solid media, suggesting a possible role in cell density sensing.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
