摘　　要：低温是影响植物生长发育以及植被分布的重要环境因子。目前,低温信号研究中比较清楚的是CBF依赖的低温信号途径。该文总结了近年来有关CBF的研究成果,详细介绍了CBF家族成员在植物耐寒性中的重要作用,着重分析与讨论CBF介导的低温调控网络及一系列复杂调控机制。理解CBF的复杂作用机制有助于了解植物中CBF介导的冷信号如何平衡耐寒性与生长发育,进而有助于耐寒作物的培育。Cold stress is an important environmental factor that affects plant growth and development as well as plant distribution. The CBF-dependent cold signaling pathway has been extensively studied. In this review, we summarize the latest advances in research of CBF genes, revealing the important role of CBFs in freezing tolerance and in chilling resistance of plants. The understanding of the CBF regulatory mechanism network at multiple levels will provide new insights into how CBF-mediated cold signaling balances tolerance and growth in plants, which may help to improve coldstress tolerance in crops.
