Abstract

The nuclear factor-Y (NF-Y) transcription factor, also known as heme-activator protein (HAP) or CCAAT-binding factor (CBF), is a critical transcription factor widely present in eukaryotes. The number of NF-Y subunits has significantly increased in higher plants compared to animals and fungi. The NF-Y complex is composed of three subunits: (1) NF-YA; (2) NF-YB; and (3) NF-YC. NF-YB and NF-YC contain histone fold domains (HFDs), which can interact with NF-YA or other transcription factors, or directly bind to the promoter CCAAT box to regulate the transcription of downstream genes. NF-Y plays a significant role in various plant processes, including growth and development. This review elucidates the structural and functional aspects of NF-Y subunits, identified NF-Y complexes, and their molecular regulatory mechanisms. Understanding these facets of NF-Y provides valuable insights into advancing crop genetic improvement and promoting sustainable agricultural practices.

核因子- y转录因子在植物生长发育中的作用。

核因子- y （NF-Y）转录因子，也被称为血红素激活蛋白（HAP）或ccaat结合因子（CBF），是广泛存在于真核生物中的关键转录因子。与动物和真菌相比，高等植物中NF-Y亚基的数量显著增加。NF-Y复合物由三个亚基组成：(1)NF-YA；(2) NF-YB;(3) NF-YC。NF-YB和NF-YC含有组蛋白折叠结构域（HFDs），可与NF-YA或其他转录因子相互作用，或直接结合启动子CCAAT盒调节下游基因的转录。NF-Y在包括生长发育在内的各种植物过程中起着重要作用。本文综述了NF-Y亚基的结构和功能、已鉴定的NF-Y复合物及其分子调控机制。了解NF-Y的这些方面为推进作物遗传改良和促进可持续农业实践提供了宝贵的见解。

期刊介绍： Functional Plant Biology (formerly known as Australian Journal of Plant Physiology) publishes papers of a broad interest that advance our knowledge on mechanisms by which plants operate and interact with environment. Of specific interest are mechanisms and signal transduction pathways by which plants adapt to extreme environmental conditions such as high and low temperatures, drought, flooding, salinity, pathogens, and other major abiotic and biotic stress factors. FPB also encourages papers on emerging concepts and new tools in plant biology, and studies on the following functional areas encompassing work from the molecular through whole plant to community scale. FPB does not publish merely phenomenological observations or findings of merely applied significance. Functional Plant Biology is published with the endorsement of the Commonwealth Scientific and Industrial Research Organisation (CSIRO) and the Australian Academy of Science. Functional Plant Biology is published in affiliation with the Federation of European Societies of Plant Biology and in Australia, is associated with the Australian Society of Plant Scientists and the New Zealand Society of Plant Biologists.
