Movement and Persistence of Genes in the Environment

Issues on gene and seed movement go beyond the GM debate, and indeed, the major current research here on geneflow uses non-GM markers. The group combines statistical, molecular, genetic, mathematical and ecological skills to investigate the movement of genetic material and its consequences. It maintains large study areas in Tayside and in England in which it tracks the occurrence and persistence of volunteers, ferals and wild relatives.

Research projects

Research has developed in this topic for more than ten years through a series of projects funded from Europe, the UK and Scotland and from the research councils in collaboration with universities. Our contributions over this period include:

Ecological biosafety and gene flow

We examine their potential roles in cropping systems, their positive and negative environmental effects, the movement of genetic material through pollen and seed and the  means by which GM and other crops might coexist in European agriculture. We combine knowledge of biology, modelling and molecular science to answer some of the most important topical questions in ecological biosafety. All our findings are made public. Members of the group are regularly invited to advise national and international commissions in biosafety and to develop training methods for environmental risk assessment.
