=Morning Meeting=

To do in lab
1. Transform & Selection We transform these following 14 parts today. B0015 Plate 1 23L   S03878 Plate2 16M C0179 Pate 2 8M    C0070 Plate2  12H F1610 Plate2 24G    B0034 Plate1 2M I0462 Plate1 8O     C0078 Plate1 14D C0077 Plate1 14A   I1466 Plate1 23J 2. Breeding 3. Refinement
 * Medium buildng
 * LB
 * LB Amp+
 * LB Kan+
 * Transformation
 * About 16 kinds of parts

To bring

 * Timer
 * Pen
 * Slipper

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. reported by Tadasi Nakamura
