Polychlorinated biphenyls (PCBs) are persistent organic pollutants damaging to human health and the environment. Techniques to indicate PCB contamination in planta are of great interest to phytoremediation.
PCBs can be divided into two groups:dioxin-like PCBs and non-dioxin-like PCBs. In mammalian cells DL-PCBs are recognized by the aryl hydrocarbon receptor (AHR) system, while NDL-PCBs are recognized by pregnane Ⅹ receptor (PXR) system. Monitoring of DL-PCBs in transgenic plants carrying the mammalian ...
