Abstract
By comparing potential and actual risks in both fields of agriculture, with or without GMOs, we need a clear view of the similarities and differences. Raamsdonk (1993) has given a scheme of gene flow, whether natural or influenced by human activity. It clearly shows that most pathways of gene flow are both natural and also strongly influenced by agriculture and breeding. But there is one notable exception: Transformation is something quite new. It is now possible to jump over the limits of species, genera and even families and orders in a much easier way. Let’s not forget that there is something universal about the sequences used for transformation and often lay persons are puzzled by expressions like “a fish gene” for instance. They have not the knowledge how to judge the novelty of such transformation. But this statement also counts for the experts: position effects and pleiotropic effects after transformation have to be considered in all cases, this is why we need to think about new risk assessment methods for genetic engineering. But we should always be aware of the fact that classical breeding is also dealing with the introduction of genes to a crop plant. The big difference is that these genes introduced in classical breeding are always belonging to some relatively close parents, transformation is always done in the relatively narrow environment of interbreeding species groups. But again we have to consider all cases in classical breeding, where single gene mutations or the change of only a small number of genes has dramatically changed morphology, growth and yield of a crop, especially in the case of maize and wheat. Considering the possible escape of transgenes to wild relatives there are parallels between classical breeding and genetic engineering regarding the processes of vertical gene flow, but the results may be different in the case of a possible escape of a novel transgene having new ecological potential.
