Elucidation of molecular mechanisms underlying inhibitory effects of glutathione on cadmium translocation and accumulation in plants

随着人们对食品安全问题的日益关注，建立一种新的降低作物中有害重金属元素镉（Cd）含量的技术已成为一个迫切的问题。在本研究中，我们发现，谷胱甘肽（GSH），这是适用于植物根特异性，抑制镉从根到地上部和镉在地上部的积累。利用这一现象进行研究，以期建立一种新的栽培技术，供实际应用。在本研究中，我们试图阐明这一现象的分子机制。我们发现，这种现象的原因之一是谷胱甘肽，施加到根，激活镉流出他们的根。

Growing interests in food safety make it an urgent issue to establish a new technique to reduce cadmium (Cd), which is one of harmful heavy metal elements, in crop plants. In our research, we found that glutathione (GSH), which was applied to plant roots site-specifically, inhibited Cd translocation from roots to shoots and Cd accumulation in their shoots. It is expected to establish a novel cultivation technique by applying this phenomenon and carrying out some research for practical use. In this research, we tried to elucidate the molecular mechanism of this phenomenon. We found one of the causes for this phenomenon was that glutathione, applied to roots, activated Cd efflux from their roots.
