description

Concerns have been raised about the possibility of the negative impact of transgenic crops on the environment. If wild plants accidentally pick up transgenes through pollen exchange with genetically modified crops, they could gain new environmental advantages or conversely suffer genetic homogenization and loss of biodiversity. This could cause weeds that might create new problems in farmers' fields and wild habitats and change biological equilibriums. Examples of gene flow are given for several cases of crop/ancestor pairs and two cases of more distantly related species. The main concern is that introgression between transgenic, insect-resistant crops and their wild relatives could lead to a progressive increase of the frequency of insect-resistant plants in wild populations. However, data are presently scarce to establish a firm scenario of the fate of such insect-resistant populations.
