Abstract:

The possible impacts of transgene flow on environment and human health is one of the safety issues of GMC (genetically

modified crops) concerned by the scientific community and public. Although existing technologies (such as distance or

flowering time isolation and physical barrier, etc.) may limit or reduce transgene flow, however, it is not able to avoid the

gene flow fundamentally. In recent years, the development of a new strategy to control transgene flow via biological

containment has become a hot spot internationally. Current biological containments of gene flow include chloroplast

transformation, male sterility, seed sterility, cleistogamy, apomixes,transgene mitigation, gene split and gene deletion,

etc.

Key words:  gene flow, biological containment
