ABSTRACT
The definitions of the terms weed, weediness, feral crops, and domestication of crops are discussed and defined in Chapter 2. From the ecologists’ perspective, invasions of weeds into seminatural and natural plant communities are potentially risky (3,4). These problems are not focused on transgenic plants alone. It is just the bad luck of this new and elegant technique that it offers more clarity to the agroecologists, because transgenes can be precisely followed on a long-term basis. It is now emerging through new field research that, according to Sears et al. (45), the present day transgenes (e.g., Bt proteins to create insect resistance) do not have a dramatic impact on ecosystems in the field, while earlier lab studies of Losey et al. (30) and also Hilbeck et al. (21) showing toxic effect are questioned in the light of new studies (38). It will be a future chance to follow transgenes and their fate in agricultural systems. Thus, we will learn about crops and their wild relatives and feral populations.
