摘　　要：HAP(NF-Y或CBF)是一类重要的转录因子,可以与CCAAT框结合并控制基因的表达,广泛分布于酵母、哺乳动物及植物细胞中。在哺乳动物和植物细胞中,HAP复合体包括3个不同的亚基:HAP2/NF-YA/CBF-B、HAP3/NF-YB/CBF-A及HAP5/NF-YC/CBF-C。HAP3转录因子在植物胚胎发育、叶绿素生物合成、花期调控等方面有重要作用。介绍植物HAP3转录因子结构特点、生物学功能等方面的最新研究进展。The Nuclear Factor Y（HAP or CBF）protein is one kind of important transcription factors which occur in yeasts,mammals and plants.It can bind to the CCAAT box and regulate the expression of target genes.In mammals and plants,HAP complex includes three subunits named HAP2（NF-YA or CBF-B）,HAP3（NF-YB or CBF-A）and HAP5（NF-YC or CBF-C）.The HAP3 subunits control diverse developmental processes in flowering plants such as embryonic development,chloroplast biogenesis and flowering control.This paper was mainly focused on the structure of HAP3 subunit and advances of its biological functions.
