The invention relates to the technical field of gene engineering, in particular to CpCAF1 gene promoters of Chinonanthus praecox(L.) Link and application of the CpCAF1 gene promoters. The invention aims to provide new plant-derived promoter resources for gene engineering improvement of plants. The invention provides Chinonanthus praecox(L.) Link CpCAF1 gene promoters of four different lengths. Thepromoters are constitutive promoters, up regulation of the expression level of downstream genes can be achieved under the induction action of abiotic stress. A reference is provided for related regulation of the adversity stress of Chinonanthus praecox(L.) Link through the study of the promoters, and meanwhile, a new choice is provided for the research of gene engineering of plants. 本发明涉及基因工程技术领域，具体地说，涉及蜡梅CpCAF1基因启动子及其用途。本发明要解决的技术问题是为植物的基因工程改良提供新的植物来源的启动子资源。本发明提供了4种不同长度的蜡梅CpCAFI基因启动子。该启动子为组成型启动子，在非生物胁迫诱导下能上调下游基因的表达量。该启动子的研究为蜡梅逆境胁迫相关调控提供参考，同时也为植物基因工程的研究提供了新选择。
