Design genetic circuits

We have thus far focused our attention on signaling molecules used in quorum sensing systems of bacteria. The ones we will be using are as shown below:
　 *Inducer ⇒（synthesize) Signal molecule ⇒ Receptor 

* LuxI ⇒　    3OC6HSL　     　⇒ LuxR → positive regulation
* LasI ⇒　　AI-1(3OC12HSL) 　⇒　LasR → positive regulation
* CinI  ⇒  　3OH,C14:1-HSl  　⇒　CinR → positive regulation
* RhlI ⇒　　AI-1(C4HSL)  　　 ⇒　RhlR → positive regulation
* AgrB synthesizes AIP from AgrD ⇒ AIP diffuses and attaches to AgrC ⇒ AgrC phosphorylates 
and activates AgrA which then promotes transcription at P2 and P3 promoters.

 From now on,We have to do what I mention below
 1.Investigate other cell-cell comunication systems (besides those used in quorum-sensing).
 2.Check to ensure that system components are working properly.
 3.Create new systems or implement additional cell functions.
 4.Investigate the possibility and extent of cross talk between various signaling molecules.
