9th International Symposium on the Biosafety of Genetically Modified Organisms. Session VI: Estimating likelihood and exposure, Part II.

چکیده
Exposure or likelihood of occurrence of an identified hazard is a key factor used by regulators in determining the magnitude of risk. One example of exposure is the amount of gene flow between transgenic crops and their non-transgenic counterparts or their compatible wild relatives. Gene flow itself is not a hazard, but instead represents the exposure of the environment to transgenes and the potentially novel traits that they produce. In assessing the risk presented by transgenes, the amount of gene flow may vary geographically, and depends upon several factors, including climatic conditions, existing pollinators, and day length. The variability in levels of gene flow makes it sensible to make a worst-case assumption when estimating exposure from gene flow; that is, to assume that gene flow and introgression will occur to other compatible populations, particularly wild relatives. Consequently, the most important fact to establish is whether or not gene flow can occur. Determining the precise amount of gene flow and its geographic variation

9th International Symposium on the Biosafety of Genetically Modified Organisms. Session III: Identifying and defining hazards and potential consequences II.
This session examined how effects of GM plants can be distinguished from those of non-GM comparators, how these differences can be measured, and how effects on non-targets and on plant fitness can be assessed. This review focuses on issues concerning plant fitness and invasiveness, and explores how the consequences of changes can be evaluated in terms of their environmental impact for risk asse...
