Parts construction:
Origins of TetO Array are from pDAG479 of D. Lane (Toulouse 2 University).

Cloning plan of TetO array construction

We characterize it with arabinose-induced YFP:TetR Wild Type from pFX234 plasmid of F-X Barre and D. Lane (Kinetics of plasmid segregation, Molecular Microbiology, 2004).

Microscopy of double transformated pFX234 / Biobricked TetO Array E. Coli:
In order to do this characterization, we took pictures of different plasmids containing only TetO array (K606026); TetR + YFP (pFX234); TetO + TetR + YFP (K606026 and pFX234). In each case we made a control by non inducing the promoter with arabinose. Cells were grown at 37°C and induced at least 45min.

tetO array : 37°C
tetO / TetO array induced without arabinose on E. Coli .	tetO / TetO array induced without arabinose on E. Coli .
tetO / TetO array induced with 0,2% arabinose on E. Coli .	tetO / TetO array induced with 0,2% arabinose on E. Coli .

TetR:YFP : 37°C
tetR:YFP / TetR-YFP induced without arabinose on E. Coli .	tetR:YFP / TetR-YFP induced without arabinose on E. Coli .
tetR:YFP / TetR-YFP induced with 0,2% arabinose on E. Coli .	tetR:YFP / TetR-YFP induced with 0,2% arabinose on E. Coli .

The pictures of TetO show no YFP activity, which is normal because there is no YFP sequence in these plasmids.
The TetR-YFP construct which constitutes the transmitter part, occasionally shows gross aggregated YFP. This is not what we expected at first, but that does not prevent us to characterize the full construct.
