METHODS AND COMPOSITIONS TO REDUCE OR ELIMINATE TRMETHODS AND COMPOSITIONS TO REDUCE OR ELIMINATE TRANSMISSIONOF A TRANSGENE ANSMISSIONOF A TRANSGENE

摘要

Genetic constructs and methods are disclosed for the production, maintenance and control of transgenes in transgenic eukaryotic organisms that undergo meiosis in which pollen or sperm can be outcrossed; this includes: transgeni c animals, plant cells, plant tissues and whole plants. More specifically, thi s invention relates to the control of transgene transmission by male and/or female gametes or gametophytes using a gametophytic sterility trait (GST). T he genetic constructs and methodologies of the present invention provide the ability to control the undesired spread of transgenes. In addition, this invention also provides the tools and methodologies to enrich a plant or oth er eukaryotic genome for dispersed and/or stable transposition events.
