草

The reason is that驱蚊草contains a special "small raw materials", the use of transgenic technology, will have the mosquito genome - the genetic structure of implanted Citronellal "vanilla", using their own unique delivery system as a vector to Shannon Mao aldehyde substances released into the air stream.

原因是驱蚊草含有一种特别的"小原料"，其采用转基因技术，将具有驱蚊基因——香茅醛基因结构植入"香草"，利用其自身独有的释放系统作为载体，将香茅醛物质源源不断释放于空气中。

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.

中文题名鸭跖草对铜的耐性机理和富集特征研究副题名外文题名 Mechanisms of Cu tolerance and accumulation by Commelina communis 论文作者廖斌导师蓝崇钰束文圣学科专业环境科学研究领域\研究方向学位级别博士学位授予单位中山大学学位授予日期2003 论文页码总数128页关键词重金属污染植物修复超富集植物土壤污染铜污染鸭跖草馆藏号BSLW /2003 /X53 /12 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。

The phylogenetic trees supported that Eriocaulaceae be treated as Eriocaulales because this family always been a nature independent group connected with other families. Eriocaulaceae grouped with Commelinaceae, which supported the close relationship and parallel evolution between the two families. Juncaceae was not close to Eriocaulaceae and more primitive. The relationship between Juncaceae and Cyperaceae was closer than that between Juncaceae and Poaceae. Among these families, Poaceae was the most primitive family and far from Eriocaulaceae. Also in Eriocaulaceae, Eriocaulon was supported to be more primitive.

从构建的系统发育树可以得到：①谷精草科独立形成一个植物类群，支持谷精草科独立成为谷精草目；②谷精草科与鸭跖草科聚成一个大的类群，说明两科的亲缘关系较近，并且表现为平行进化；③灯心草科不近缘于谷精草科，与禾本科相比，灯芯草科与莎草科之间存在更近的亲缘关系；④在进化程度上，灯心草科比谷精草科原始；禾本科与谷精草科的亲缘关系最远，并且在这几个科中处于最原始的进化地位；⑤系统树还支持谷精草科内部的系统关系，支持谷精草属在谷精草科中的原始系统位置。
