植物抗冻基因研究进展

Progress in the Studies of Plant Antifreeze Gene

低温是作物生长一大限制因素,许多作物不能在低温下生长或者容易受到冻害,所以通过基因工程的方法,转入抗冻基因,是扩大作物生长区域,稳定作物产量的有效办法。目前通过对植物抗冻基因在抗冻机理、研究技术、应用等方面的研究,已经取得了一定的成果。综述抗冻基因的来源、抗冻机理、研究技术,并做适度的展望。

The temperature is a major crop growth constraints,and many crops can not grow at low temperatures,or susceptible to damage,so through genetic engineering methods,we could impor antifreeze gene into crop.This method could expand the crop area and make the yield stability.The current through the antifreeze gene in antifreeze mechanism,research techniques,application of research,has achieved some results.This article reviewed the source of antifreeze genes,antifreeze mechanism,research techniques,and moderate outlook.
