Although it's associated with nasty cigarettes, the tobacco plant is also a potential source of vaccines, biofuel and antibiotics. Now, a chemical from the plant is also being used as a bug repellent for crops, which could replace eco-unfriendly insecticides.
Led by Prof. Thomas Brück, a team from the Technical University of Munich isolated the sections of the tobacco plant genome responsible for the formation of CBTol molecules, and then incorporated those into the genome of genetically-modified E. coli bacteria. When fed with wheat bran (obtained as a byproduct from grain mills), those bacteria subsequently produced CBTol.
