Project overview
We control the timing of gene expression by using multiple signaling devices.
To this end,we utilize molecules associated with Quorum sensing, a phenomenon that allows bacteria to communicate with each other.Our project uses two classes of bacteria: senders and receivers. Senders produce signaling molecules, and Receivers are activated only after a particular concentration of this molecule is reached.Although different quorum sensing species have slightly different signaling molecules, these molecules are not completely specific to their hosts and cross-species reactivity is observed.Communication using non-endogenous molecules is less sensitive,and requires a higher signal concentration to take effect.
This results in slower activation of receivers.
