Transition to quorum sensing in an Agrobacterium population: A stochastic model. by Andrew B Goryachev, Da-Jun Toh, Keng Boon Wee, Travis Lee, Hai-Bao Zhang, Lian-Hui Zhang

“…We construct a model describing the Ti plasmid quorum-sensing gene network and demonstrate that it behaves as an "on-off" gene expression switch that is robust to molecular noise and that activates the plasmid conjugation program in response to the increase in autoinducer concentration. …”
