| 摘 要： | 植物源食物是人类摄入有毒金属元素镉(Cd)和砷(As)的主要途径。深化植物对Cd和As积累途径分子机制的认识,有助于培育可食部分中低有毒金属元素含量的作物新种质。该文基于近年来有关植物Cd和As积累在主要模式植物中所取得的实质性研究进展,对植物介导Cd和As吸收的转运蛋白、As形态和生物转化机制以及控制Cd和As根-地上部转运效率和分配的关键因子等方面的研究进展进行综述,并对未来的研究前景进行了展望。

| Abstract: | Consumption of plant derived food is considered as the main source for intake of toxic element cadmium (Cd) and arsenic (As) in human. Deepening the molecular understanding of the pathways responsible for Cd and As can enable the development of crop varieties with low toxic metal element contents in their edible parts. Based on substantial research progress of Cd and As accumulation in model plants in recent years, transporters mediating the uptake of Cd and As, the speciation and biotransformation mechanisms of As, factors controlling the efficiency of root to shoot translocation and the partitioning of Cd and As through the node have been reviewed and the prospects in this field have also been proposed. |
