Design notes

We cloned synthetic TH into pUAST with restriction endonuclease digestion and T4 ligase igation. Then we construct pSB1C3-UAS-TH and pUAST-UAS-TH. The pSB1C3-UAS-TH is for submission. The pUAST-UAS-TH also with the other two plasmids: pUAST-ple-GAL4 (BBa_K2374005)and pUAST-ple-GAL80ts (BBa_K2374006) are used to do micro-injection into the D.melanogaster. We must combine the three pathways to determine if the system work well. After hybridization screening, we got stable modified fruit fly strains. Finally, we did RT-PCR, qPCR and behavioral experiments to test our system.
The result of our testing on D.melanogaster is displayed below.

Test Results

1. Use Real-time PCR to detect whether the expression of TH is increased at 29°C. It shows that the relative expression of TH in modified fruit flies increased significantly.

2. Detect male-male courtship when raising the temperature. Mating index refers to the relative time that the fruit fly use for mating.
It shows that he mating index of the treated group rises significantly in at 29°C. [time=5minutes, n=5, P<0.01]
