摘    要:低湿寒害是限制农作物产量和分布的一种全球性的自然灾害。提高农作物的抗寒性具有重要意义。目前随着植物寒害机理、抗寒冻和冷驯化分子机理的深入发展,已研究发现了多种抗寒基因,包括各种抗寒调控基因和各种抗寒功能基因,从而使植物抗寒冻基因工程的研究与应用得以了广泛开展,以期最终有效地提高农作物的抗寒性,增加农业产量。本文综合概述了国内外有关植物抗寒冻基因工程的最新研究方向、进展及成就,并提出了此领域尚存在的一些问题及其前景展望。

关 键 词:抗寒冻  冷驯化  分子机理  抗寒基因  基因工程  植物

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.
Keywords:Cold resistance  Cold acclimation  Molecular mechanisms  Cold_resistant genes    Genetic engineering
