Increase of glutathione in mine population of Sedum alfredii: A Zn hyperaccumulator and Pb accumulator

Sedum alfredii is a new Zn hyperaccumulator and Pb accumulator found at an old Pb/Zn mine in China. Phytochelatins and other low molecular weight thiols were examined in tissue parts of the mine and control plants of S. alfredii exposed to Zn and Pb using a RP-HPLC pre-column derivatization with monobromobimane (mBBr).
