Phytophthora Toehold w/ GFP Reporter
Design
The construction of a disease-specific biosensor required us to find a gene unique to the pathogen. When the switch turns on and GFP is expressed, we can confirm that the specific pathogen is present. For the detection of Phytophthora cryptogea, Lambert iGEM focused on the X24 gene. This gene was selected because it was required for pathogenicity and was unique to the species of interest. Biosafety note, the trigger sequence is not the full transcript sequence and therefore poses limited biosafety. We obtained the sequence via UniProt, an online database of protein sequences. Lambert iGEM used the code from Takahashi et. al provided by Megan McSweeney from the Styczynski Lab at the Georgia Institute of Technology to design the switch and trigger sequences on NUPACK. The team selected the pair from NUPACK with the lowest normalized ensemble defect (NED) to maximize the chances of successful compatibility. Once we obtained the sequences for the toehold pair, we constructed the toehold and trigger via SnapGene.
