Since 1990 green biotechnology releases many transgenic plants into the environment by selling genetically modified seeds. Thus organic farmers need to prove today, that their products meet the requirements for organic crops. Usually they pay laboratories to attest that this is the case. The new tools of molecular biology, TAL effectors, combined with our Sporobeads could be an easy and cheap solution for organic agriculture. Farmers could in future use our kit with TALE-''lacZ''-'''Sporo'''beads to detect genetically modified crops themselves. As spores are stable and safe vehicles, they could be send by mail without any considerations. The kit would be suitable for use outside of laboraty. The protocol for this could work as follows:

iGEM Ludwig-Maximilians-Universität München Beadzillus

Team-LMU Photo2.jpg

The LMU-Munich team is exuberantly happy about the great success at the World Championship Jamboree in Boston. Our project Beadzillus finished 4th and won the prize for the "Best Wiki" (with Slovenia) and "Best New Application Project".
