The invention relates to the technical field of oil crops, in particular to a promoter of a brassica napus oil content related gene BnbZIP16 and application of the promoter. It is found for the first time that the key gene BnbZIP16 for regulating and controlling grease metabolism has two types of promoters, and different types of promoters regulate and control the oil content of rape seeds by regulating and controlling the expression quantity of the gene BnbZIP16 in rape. On the basis, a promoter sequence or a promoter characteristic sequence is taken as a haplotype molecular marker, a high-oil-content rape variety is screened, and rape molecular breeding is realized. 本发明涉及油料作物技术领域，尤其涉及甘蓝型油菜油含量相关基因BnbZIP16的启动子及其应用。本发明首次发现，调控油脂代谢的关键基因BnbZIP16具备两种类型的启动子，不同类型的启动子通过调控BnbZIP16基因在油菜中的表达量，调控油菜种子的油含量。基于此，本发明以启动子序列或启动子特征序列作为单倍型分子标记，筛选高油含量的油菜品种，实现油菜分子育种。
