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.

论文以本实验室报道的生长于矿山上的铜超富集植物鸭跖草和生长于正常土壤中的鸭跖草为试验材料，分别运用溶液培养法、ICP-AES元素测定技术、差速离心法和化学试剂逐步提取法、抑制消减杂交技术、RAPD技术研究了矿山和非矿山两种生境鸭跖草对铜的耐性和吸收积累的差异，两种生境鸭跖草在铜胁迫下养分吸收和积累的差异，两种生境鸭跖草在铜胁迫下生理反应的差异，以及铜在鸭跖草细胞内的分布及结合形态研究，矿山鸭跖草差异表达的cDNA克隆，铜对鸭跖草种群遗传分化的影响，从这几个方面探讨了矿山鸭跖草对铜的耐性机理。

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.
