The University of Guelph is a mid sized, comprehensive University that is generally regarded as Canada's agricultural university and outstanding in the field of life sciences. Our university motto is actually, "Changing lives, improving life." Add the words, "using synthetic biology" to that motto and you've got a university which was made to participate in iGEM.
This is our first year in the competition, although it is hoped that it will take root here and become a creative outlet for students to use competition as a primer for research and development that will help sustainably and profoundly help the world's biological science tackle problems of food, medicine, and material production that we face. Maybe it will even give our careers credibility, jump starts, and enthusiasm? Initial funding for the team was provided for us by the Gordon Nixon Leadership Award, which was won by our iGEM superman David earlier this year. Subsequent partnerships and sponsors have given us products to work with (NEB and IDT), an operating budget (Departments of Plant Agriculture, Graduate Student Association, and Molecular Cellular Biology), and lab equipment and space (Dr. Manish Raizada). It has been hard to organize and bushwhack through a totally new realm, but we hope next year we'll get funding for paid positions and University recognized course credit to help ensure this adventure in synthetic biology will continue and benefit future groups of grad students and undergrads.

| Plants and animals are found to contain huge numbers of bacteria and fungi that help with nutrient absorption, produce beneficial compounds, fight off pathogens, or often are even pathogens themselves. We are interested in taking advantage of some of these microbes to deliver transgenic payloads for the benefit or modification of the host organism. These might be called GM endosymbionts. On the human side, we would like to introduce the carotendoid metabolic genes from a well studied soil microbe called Erwinia urodevora into human probiotic microbes which will survive and colonize the intestine for stable production of the essential human nutrient, pro-vitamin A. Time permitting, we will attempt to enhance carotenoid accumulation by increasing plasma membrane sink by overexpression of the fumarate reductase operon. Millions of humans suffer from vitamin A deficiencies across the world, resulting in blindness and death which could be mitigated by symbitic production of this important vitamin. In an exciting partnership with iGEM Calgary Ethics, they are helping us explore issues associated with this technology and potential target markets which might benefit from our project.
A more basic project will focus on RNAi signal delivery by a corn plant endosymbiont to silence corn genes. Most euaryotes react to double stranded RNA by copying it and chopping up any mRNA with the same sequence, while prokaryotes do not seem to posses the same response. Since bacteria like K. pneumonii live in large stable populations within corn plants, it is believed that as individual bacteria grow, die and lyse within the plant host, they will release RNAi transcripts into the sensitive host during the entire life cycle of the plant, which will silence the targeted gene and show a phenotype indicating gene function. Bacterial Induced Gene Silencing (BIGS) will be a useful, quick, and stable alternative for plant functional genomic research. |
