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.
