Our long term goals are to develop plant biosensors that reliably measure changes in the local environment. In the process of developing biosensors, the 2010 Nevada iGEM Team need to develop fundamental promoters, reporters, and plasmids for plants. Therefore, the 2010 Nevada iGEM Team has three goals for this year’s competition. First, we are going to test the validity of utilizing Nicotiana tabacum (NT cells) as a model for the expression of higher plant genes for future iGEM competitions. NT cells are a faster, cheaper, and safer model than traditional plant transformation. These cells can therefore be utilized as a quick proof-of-concept test model before moving synthetic constructs into plants of interest. We also aim to produce an iGEM-compatible plant-specific plasmid, several stress-inducible plant promoters, reporter genes containing Kozak sequences (ribosome binding sites) and terminators that conform to BioBrick standards. Lastly, we hope to measure the induction of these stress promoters in real-time by performing a fluorometry assay in which stress will be applied to NT cells and fluorescent output by a reporter (GFP) will be measured to detail induction in real time. This method has a distinct advantage over microarrays since microarrays are only one ‘snapshot’ in time.
