Cold stress is one of the major environmental factors that affect the geological distribution and seasonal growth of the plants. Being exposed to low non-freezing temperature would increase plants’resistance to freezing temperature by a process called cold acclimation. During cold acclimation,plants sense the environmental low temperature,initiate cold signal transduction pathways and change the expression of genes that are critical for plants to survive the freezing temperature. In this review,we focused on recent progresses regarding our understanding of cold signal transduction mechanisms,which including the newly discovered cold signaling components CHILLING-TOLERANCE DIVERGENCE 1(COLD1)and OPEN STOMATA1(OST1);transcriptomic studies of C-REPEAT BINDING FACTORS (CBFs)triple mutant created by CRISPR/Cas9 technology and proteomic study of early cold regulated proteins etc. Based on these results,a cold signal transduction model is summarized.%低温胁迫能限制植物地理分布并影响作物产量，但是在适宜的低温条件下处理一段时间后植物就可以获得更强的抗冷和抗冻能力，这个过程称为冷驯化。在冷驯化的过程中，植物感知环境低温，通过一系列信号传导事件调节耐冷相关基因的表达，提高植物的耐冷性。介绍了目前冷信号传导机制研究的一些新进展：包括新发现的冷信号传导途径的上游组分 CHILLING-TOLERANCE DIVERGENCE 1（COLD1）和 OPEN STOMATA1（OST1）；对冷信号途径中关键转录因子 C-REPEAT BINDING FACTORS（CBFs）进行 CRISPR/Cas9敲除后的转录组测序结果以及短时间冷胁迫处理的蛋白质组学研究结果等。并且根据这些研究进展，总结了一个冷信号传导途径的模式图。
