摘要: 铁蛋白(ferritin)是一种铁结合和存储蛋白,广泛存在于动物、植物和微生物体内,是生物体内的一种保守性较高的多功能多亚基蛋白。植物铁蛋白作为专门的贮铁蛋白,是植物光合作用和固氮等生化反应的铁源,不仅调节体内铁的含量,而且是一种重要的胁迫反应蛋白,调控铁生物功能,在植物的发育、抵抗氧化损害等方面发挥重要的作用。本研究从铁蛋白的结构、功能及基因克隆、表达和遗传转化等方面,概述了其在植物分子生物学中的研究进展及其应用情况。

Abstract: Ferritins (iron-binding protein) are ubiquitous iron storage proteins in plants, animals, and microorganisms. They are highly conserved, multi-functional and multi-subunit proteins. Plant ferritin, as a special iron storage protein, is the source of iron for plant biochemical reactions such as photosynthesis and nitrogen fixation. It can regulate iron content and plant biological functions, is an important stress response protein, and plays a key role in plant development and anti-oxidation. This paper summarizes research progress and the applications of ferritin in plant molecular biology in terms of its structure, function, gene cloning, expression and genetic transformation.
