Title: Evolutionary Impacts Caused by Transgene Flow into Rice Wild Relatives

Abstract: The potential ecological and evolutionary risks caused by transgene escape from crops to wild relative species through gene flow have aroused tremendous debates over environmental biosafety issues worldwide. Previous studies indicate that transgene flow frequencies and fitness effects are the keys to determining ecological consequences. In this seminar I will provide a short introduction to the status of GE crops in China, including crops and traits being grown widely and in the pipeline. After that, I will present a case study of fitness effect of transgenes in wild rice and weedy rice based on our long-term field research in China. The result revealed different ecological and evolutionary impact of transgenes in these species case-by-case. Findings from this study also provide insights about functional genes with a strong selective advantage on the adaptive evolution of wild relative species during the hybridization-introgression process.
