Evolutionary theory of hybridization-introgression:its implication in environmental risk assessment and research of transgene escape

The commercialization of genetically modified(GM)flee(Oryza sativa)may arouse environmental biosafety concerns, including the impacts of transgenes on non-target organisms and biodiversity,transgene escape and its related ecological conse- quences,and transgenic influences on soil micro-fauna from extensive cultivation of GM flee.

It also analyzes the functional mechanisms and potential impacts,especially their possibilities to prevent transgene escape.

High risks of transgenic escape have been found in some crops.

This minireview describes some mo-lecular strategies for control transgenes escape, including maternal inheritance, male sterility, seed sterility, andincompatible genomes.

This paper,based on the exact Voigt profile we obtained,discusses the resonance escape factors and the transition probabilities of two resonance absorption lines that make up the MgⅡ280nm line for both Gaussian and Lorentzian profile.

Research on the problem of"death caused by escaping"in the crime of traffic accident;

Try to analyze the reason and countermeasure about escaped case for traffic cause trouble;

On"death caused by escape"in the crime of traffic accident;

However,along with the high-speed development,its inevitable sideline product——traffic accident occurs! Facing the increasing escape behaviors of taffic casualities,not only the legislative managements but also the judicial regulations are not very ideal.
