Abstract:Chilling and freezing injusy is one of the global natural disasters which can cause significant loss in plant productivity and limit areas of agricultural production. Hence it is important to improve the cold resistance of crops. Recently, due to the great advances in the researches of molecular mechanisms of cold injury, cold resistance and cold acclimation, many cold_resistant genes have been found, including all kinds of regulatory genes and functional genes. Thus the studies of genetic engineering for cold resistance in plants have also been carried out extensively in the past few years. This paper gives a general statement about recent progresses in the studies of genetic engineering of cold-resistant plants at home and abroad. In addition, some problems remaining in this field and prospects of its main strategies are discussed.
