像锰(Mn)和铁(Fe)这样的金属对新陈代谢是必不可少的，而镉(Cd)对几乎所有的生物都是有毒的。了解这些金属的运输对于培育更好的作物很重要。我们已经确定OsNRAMP5在水稻中参与了锰、铁和镉的运输。OsNRAMP5的表达仅限于根表皮、外真皮和皮层外层以及木质部周围的组织。OsNRAMP5定位于细胞膜，并补充了锰、铁和镉运输缺陷的酵母菌株的生长。OsNRAMP5 RNAi(OsNRAMP5i)植株在根中积累的锰较少，在地上部和木质部汁液中积累的锰和铁较少。OsNRAMP5基因的抑制促进了Cd向地上部的转运，突显了该基因在Cd植物修复中的重要性。这些数据表明，OsNRAMP5参与了水稻体内的锰、镉和铁的运输，对植物的生长发育具有重要意义。
Metals like manganese (Mn) and iron (Fe) are essential for metabolism, while cadmium (Cd) is toxic for virtually all living organisms. Understanding the transport of these metals is important for breeding better crops. We have identified that OsNRAMP5 contributes to Mn, Fe and Cd transport in rice. OsNRAMP5 expression was restricted to roots epidermis, exodermis, and outer layers of the cortex as well as in tissues around the xylem. OsNRAMP5 localized to the plasma membrane, and complemented the growth of yeast strains defective in Mn, Fe, and Cd transport. OsNRAMP5 RNAi (OsNRAMP5i) plants accumulated less Mn in the roots, and less Mn and Fe in shoots, and xylem sap. The suppression of OsNRAMP5 promoted Cd translocation to shoots, highlighting the importance of this gene for Cd phytoremediation. These data reveal that OsNRAMP5 contributes to Mn, Cd, and Fe transport in rice and is important for plant growth and development.
