The aim of the project is to gain an insight into international research on the environmental impact of genetically modified organisms (especially plants) and to identify the gaps in and limits to biological safety research. An initial phase takes up the methodologies used in genetic modification of plants and the associated risks. The project then focuses on general phenomena like hybridisation, horizontal gene transfer and dispersal of genetically modified organisms. New traits transferred to plants and their potential effects (direct and indirect) on the environment and biodiversity are addressed. The project also looks at the emergence of resistance traits and their impact on the use of pesticides.
