摘要： Transgenic plant technology provides a powerful tool to improve abiotic stress tolerance of crop plants. However, introgression of stress tolerance genes into weedy relatives may lead to increased potential of their persistence and invasiveness, resulting in undesirable ecological consequences. A variety of gene confinement strategies have been developed to stop unwanted transgene movement. In this review, we discuss some of these strategies, such as male and female sterility, GeneSafe, parthenocarpy, chloroplast transformation and gene deletor technologies. In the case of the gene deletor technology, it may eliminate all transgenes from pollen, seeds, fruits or other organs when their functions are no longer needed or their presence may cause concerns. The gene deletor and other technologies can be useful to reduce unintended dispersal of stress tolerance genes and thus may facilitate commercialization of transgenic crops with enhanced tolerance to abiotic stresses.
