What is it about?
We have unraveled the first plant specific pathway to detoxify polychlorinated biphenyls (PCBs) and related persistant toxicants. For this purpose, we integrated functional and structural studies in poplar and thale cress, two models in plant biology. Our results open new paths to improve the phytoremediation of PCBs, a task for which poplar trees are naturally well endowed. The alternative conventional cleanup methods are far more expensive and less environmentally friendly.

Why is it important?
PCBs are persistent organic pollutants with serious effects on human health and the biosphere. They are still being released from polluted sites and pervade the food web despite bans and restrictive international legislation. Phytoremediation offers a solar-powered and cost-efficient alternative to conventional remediation. To unlock the full potential of this technology, we need a better understanding of how plants deal with pollutants. We define here the first clear-cut plant pathway for biphenyl/PCB degradation.
