Die Anwendung von Proteinase-Inhibitoren als Bioinsektizide in transgenen Pflanzen - eine bibliographische Studie zur Risikobewertung

All plants possess a certain degree of resistance to insects and so only a limited range of herbivores are able to feed on each individual species. This inherent resistance is based on various defence mechanisms, including a wide range of noxious secondary metabolites produced by the plant. Today insect-resistance transgenes, whether of plant, bacterial or other origin, can be introduced into plants to increase the level of insect resistance, a technology that has dramatically extended the scope of resistance genes available to plant breeders. The first reports of transgenic insect-resistant plants were published in 1987, but technological development has been swift since then. The use of transgenic plants may lead to a reduction in the use of broadspectrum insecticides, thereby extending the useful life of these compounds and reducing the ecological damage they cause.
