摘　要：

核因子Y (NF-Y), 又称CCAAT盒结合因子(CBF)或亚铁血红素激活蛋白(HAP), 是一种普遍存在于酵母、哺乳动物及植物等真核生物中的转录因子, 由三种不同的亚基组成, 即NF-YA (CBF-B或HAP2)、NF-YB (CBF-A或HAP3)和NF-YC (CBF-C或HAP5)。近年来的研究发现NF-Y在植物胚胎发育、光合作用、开花时间调控、逆境胁迫响应等诸多方面起重要作用。本文简要阐述植物NF-Y的生化、互作与家族特性、基因表达调控、生物学功能等方面的研究进展。

Abstract:

Nuclear factor Y (NF-Y), also known as CCAAT-binding factor (CBF) or Heme Activator Protein (HAP), is a conserved heterotrimeric complex composed of three subunits, NF-YA (also termed CBF-B or HAP2), NF-YB (CBF-A or HAP3) and NF-YC (CBF-C or HAP5). During the last decade, extensive studies have revealed that subunits of NF-Y complex play important roles in embryonic development, photosynthesis, flowering and stress response. This review summarizes the recent research progress on the biological function of NF-Y in plants.

Key words: NF-Y transcription factors; growth and development; stress response
