Nutrition solution culture, ICP-AES, the differential centrifugation technique and sequential chemical extraction method, suppression subtractive hybridization , RAPD were used in this thesis to study the mechanisms of copper tolerance and accumulation by Commelina communis grown in copper mine deposit which was reported to be a Cu hyperaccumulator, compared with C. communis grown in normal soil. Several aspects were examined, including: difference of copper tolerance and accumulation between C. communis grown in copper mine deposit and that grown in normal soil; difference of growth and nutrient accumunation between C. communis grown in copper mine deposit and that grown in normal soil under copper treatment; physiological differences between between C. communis grown in copper mine deposit and that grown in normal soil under copper treatment; subcellular distribution and chemical forms of Cu in C. communis; identification of cDNA fragments differentially expressed in C. communis grown in copper mine deposit; genetic diversity and copper tolerance of C. communis, tolerance mechanisms to copper in C. communis are discussed.

This conclusion is based on three groups of experiments with detached root tips of wheat seedlings: By following the time course changes of NO synthase , superoxide synthase and ABA accumulation under dehydration stress, we found that ABA accumulation was preceeded by the changes of NOS and superoxide synthase. ABA accumulation induced by dehydtrion stress and osmotic stress can be blocked by NO scanvegers and NOS inhibitors, while only dehydration stress-induced ABA accumulation can be blocked by ROS scanvegers. Exogenous applied NO or ROS induced ABA accumulation in root tips of wheat seedlings, and synergistic effects were found between NO and NO. The in planta expereiments also proved that ROS and NO are involved in water stress-induced ABA accumulation.Ⅱ.
