INCREASE OF TOTAL GLUTATHIONE AS A RESPONSE TO CD INDUCED STRESS IN A CHILEAN ENDEMIC BRYOPHYTES (THUIDIUM SP.)

Bryophytes collected from the IV Region of Chile, were treated with CdCl2 to stimulate the synthesis of phytochelants. After cadmium treatment, total peptides were extracted from the plants and were analyzed using HPLC to search for the presence of phytochelatin molecules. Chromatography results sho...
