Plants evolved various mechanisms to cope with metal stress. Cadmium (Cd) exposure specifically induces the synthesis of thiol-rich substances such as phytochelatins. Due to the chemical similarity of Cd and zinc (Zn), similar detoxification mechanisms for both metals are under discussion.

升高的锌浓度不会诱导菠菜 (Spinacia oleracea) 和欧芹 (Petroselinumcrispum) 中的硫醇

植物进化出各种机制来应对金属胁迫。镉 (Cd) 暴露会特别诱导富含硫醇的物质（如植物螯合素）的合成。由于 Cd 和锌 (Zn) 的化学相似性，两种金属的类似解毒机制正在讨论中。
