We tried to clarify uptake mechanisms of persistent organic pollutants, such as dioxins, by Cucurbitaceae family. Transporting proteins in xylem sap and organic acids in root exudates were responsible for its uptake to plants. Expression of genes related to uptake in plants led to dioxin accumulation in the aerial parts of plants. These results showed that phytoremediation systems for persistent pollutants are developed by the use of functions derived from Cucurbitaceae family.

本文试图阐明葫芦科植物对二恶英等持久性有机污染物的吸收机制。木质部汁液中的蛋白质和根系分泌物中的有机酸是植物吸收的主要途径。植物吸收相关基因的表达导致二恶英在植物地上部分的积累。这些结果表明，持久性污染物的植物修复系统是利用葫芦科植物的功能开发的。
