'GRIM' and 'killer'
genes. Patents have also been granted to inducible promoters, which can be used to develop transgenic crops, the spraying of which with a chemical or the exposure of which to changed climatic conditions will activate a dormant 'suicide trait' in the insect demaging the crop.
A gene from a fly encoding 'GRIM protein' is an example. AstraZeneca also discovered 'killer genes' towards the same objective.
The use of these promoters will also be in the mutual interest of the seed company and the farmer.
