#2003 Comparison of unsprayed conventional cotton crop and Bt GM cotton in Australia

2003

Bacillus thuringiensis (Bt) is a spore-forming bacterium that produces crystal proteins that are toxic to many species of insects. Crops have been modified with short sequences of genes from Bt to express the crystal protein Bt makes. With this method, plants themselves can produce the proteins and protect themselves from insects without any external Bt and/or synthetic pesticide sprays.
