Abstract: Low temperature is one of the important environment factors affecting agriculture, especially in higher altitudes and cool areas. In the recent years, with the plant cold-resistant genetic engineering development, we have made great progress in researches of cold resistance. This paper gives a general statement about the recent development of plant cold-resistant genes from cold regulated gene, structural genes (including fatty acid desaturation metabolism enzyme gene and antioxidative enzyme gene etc.) and regulatory genes (AP2/EREBP 、NAC、MYB 、WRKY and bZIP transcription factors), aiming to provide some useful information and ideas to researchers who work on plant breeding and the mechanism of cold-resistance. As research continues, we hope that we can develop new multiple resistance plant breeds.
