Abstract:

Low temperature is one of the most important ecological factors, it effect not only the growth and development but also the areal distribution of the plants. It has the theoretical and practical significance that enhanced the cold tolerance in the cold sensitive plants. Recently, studies on antifreeze protein genes showed that they can enhance the cold tolerance in the sensitive plants obviously. In this paper a review about the present study of antifreeze protein was given in terms of antifreeze protein mechanism, as well as the improvement of the cold tolerance in the plants by transformation of antifreeze protein genes. This paper provided some enlighten on theoretical and some new idea about technology.
