Starting from construct C1, we designed an integrative plasmid that codes for LuxA and LuxB under the genomic transaldolase promoter (Pta). This time we decided to use the reverse complement of kanamycin resistance gene so both LuxAB and the resistance gene end at a double terminator sequence. You can check the problems we had with the standard kanR-double terminator (P1003+B0014) in our lab notebook.

C11.jpg

C1.1
Integrative plasmid designed for the expression of RFP under synechocystis psbAB promoter also with a kanamycin resistance cassette for selection in cyanobacteria. The construct is flanked by neutral recombination sites RS1 and RS2, homologous to synechocystis chromosome.

C1.2
This integrative plasmid is designed for the expression of RFP under synechocystis psaA2 promoter with a kanamycin resistance cassette for selection in cyanobacteria. The construct is flanked by neutral recombination sites RS1 and RS2, homologous to synechocystis chromosome.

C21.jpg

C2.1
Construct designed from pPMQAK1 expression plasmid, which replicates both in E. coli and cyanobacteria and is biobrick-compatible. It codes for RFP under synechocystis psbAB promoter.

C22.jpg

C2.2
Construct designed from pPMQAK1 expression plasmid, which replicates both in E. coli and cyanobacteria and is biobrick-compatible. It codes for RFP under synechocystis psaA2 promoter.

C31.jpg

C3
Construct designed from pPMQAK1 expression plasmid, which replicates both in E. coli and cyanobacteria and is biobrick-compatible. It codes for RFP under synechocystis psbAB promoter and cuts out the whole Ccdb toxin gene.

C4.jpg

C4
Expression plasmid for the expression of LuxA and LuxB genes under psbAB promoter.

C5.jpg

C5
Integrative plasmid designed to integrate LuxA and LuxB and a kanamycin resistance cassette downstream the 3' end of the transaldolase gene whose mRNA levels where seen to oscillate in a circadian manner peaking at hour 14, just after dusk. It is expect the same for LuxAB mRNA levels.


C6
Starting from construct C1, we designed an integrative plasmid that codes for LuxA and LuxB under the genomic transaldolase promoter (Pta). This time we decided to use the reverse complement of kanamycin resistance gene so both LuxAB and the resistance gene end at a double terminator sequence. You can check the problems we had with the standard kanR-double terminator (P1003+B0014) in our lab notebook.
