In vitro phytoextraction ability of vegetative clones of Populus canescens including two transgenic clones (ggs11 and lg16) was studied in leaf disc cultures. Clone stability was determined by fAFLP (fluorescent labelled amplified fragment length polymorphism). In total, 679 AFLP fragments were identified. Only one of them was different (99.85% genetic similarity). Presence of the gsh1 transgene in the transformed clones (ggs11 and lg16) was detected in PCR reactions using gsh1 specific primers. For the study of phytoextraction activity, leaf discs (8 mm) were exposed to a concentration series of ZnSO4 (10-1 to 10-5 M) incubated on tissue culture media WPM for 21 days. Zn2+ showed phytotoxicity only at high concentrations (10-1 to 10-2 M). Transgenic poplars showed elevated heavy metal (Zn and Cu) uptake compared to the non-transformed clones. These results suggest that transgenic poplars may be suitable for phytoremediation of soils contaminated with Zn2+
