‘Genetic modification is now taking on a new appearance. Although if you were to read many reports announcing arrival of the new technique it would sound as if it is an entirely new and separate process.
Because plants are able to “turn off” their genes through RNA interference in order to block protein translation – researchers are now attempting to weaponize this trait and genetically engineer crops that can produce specific RNA fragments that begin the process of RNA interference to shut down a specific gene which is necessary for life and reproduction.
This RNA fragment production would be set to begin upon ingestion by insects. it would then kill or sterilize the insects who have eaten the crop. The new RNA interference modification was recently reviewed in Trends in Biotechnology in the journal’s special issue on Environmental Biotechnology.’
