黄色条纹蛋白(Yellow stripe-like protein,YSL)是广泛存在于植物中的重金属吸收、转运蛋白,主要参与植物Fe3+的吸收及对Fe2+、Zn2+、Cu2+、Ni2+和Mn2+等金属离子的转运.目前,对于黄色条纹蛋白在植物体内的表达模式,亚细胞定位以及突变体等方面的研究揭示了其在植物生长发育过程中的作用.综述了近年来关于YSL基因在植物中的研究进展,旨为研究植物吸收铁的作用机理及生物强化谷物籽粒中的铁含量奠定基础.%YSL(yellow stripe-like protein)are widely present in plants for the absorption and transporter of heavy metal. They are mainly involved in the absorption of Fe3+ and the transport of metal ions such as Fe2+,Zn2+,Cu2+,Ni2+ and Mn2+. At present,the research on the expression pattern,subcellular localization and the mutant of YSL in plants reveals its role in plant growth and development. In this paper, the research progress of YSL genes in plants in recent years are reviewed,which aims to lay the foundation for studying the mechanism of plant absorbing iron and the iron content in cereal grains by the biological enhancement.
