生物多样性

019 Bacteria were detected by Miroarray in MBR. Proteobacteria was the predominant phylum. It had 657 OTUs, occupying 64.5% of the total bacteria.

As a whole, study on the six boxH/ACA snoRNA in Schizosacchromyces pombe will be helpful for us to understand the diversity of the functions and structures as well as gene organizations of snoRNA genes, and also provide new evidences for demonstration of the evolvement and origin of snoRNA genes.

粟酒裂殖酵母6个boxH/ACA snoRNA基因的结构和功能研究有助于我们进一步了解snoRNA基因的结构，功能和基因组织的多样性，也为最终阐明真核生物snoRNA基因的起源与进化提供了新的证据。

In addition, the authors suggest:① The research of firs hybridization should be carried out on a large scale in China;② In hybridization, the phylogeny of Abies must be considered, and we should put emphasis on the intro-section hybridization;③ The research on the strobili phenology of firs can ensure the hybridization succeed;④ The research is also important for the hybridization to study the genetic diversity of Abies;⑤ We can use the biotechnology and the knowledge of modern molecular biology to overcome the difficulties of breeding.

作者对我国开展这项研究提出了几点看法：①应大力开展我国冷杉树种间，以及与国外冷杉树种间的杂交研究；②杂交时必须考虑种的系统关系学并以派内杂交为主导方向；③对我国冷杉属树种进行开花结实习性研究；④开展我国冷杉属树种的系统学和遗传多样性研究；⑤结合现代生物技术和分子生物学知识，克服常规杂交中的困难。

Based on the strategy to explore microbial resource from natural environment and the fact that the majority(about 99%) of microbes in diverse environments are unculturable till now by using traditional microbiological methods,scientists try hardrounding the bottleneck to set up novel techniques to culture and study those uncultured microorganism s.

在微生物筛选过程中，99%的未培养微生物是用传统的方法无法分离的，这极大地限制了微生物生态领域中的多样性和利用生物资源等方面的研究。

We used denaturing gradient gel electrophoresis to study the diversity of picoeukaryotes in natural marine assemblages.

This volume reconfirms the diverse and unpredictable roles that non-native species assume as they invade new ecosystems: destruction of vital crops and forests, major damages to ecosystems leading to loss of biodiversity, soil erosion, and water loss.

当他们侵入新生态系统时，这卷再确认非本地种类假装的完全不同和无法预言的角色︰至关重要的庄稼和森林的损坏，主要的对生态系统的损害导致生物 Living beings 多样性，土壤腐蚀和水损失的损失

The most worrying result was the reshuffling of ecological communities-species that live together.

科学家在墨西哥进行研究，因为那里的生物具有多样性，最令人担心的结果是生态群落——居住在一起的物种——的重组。

To protect the identity of orchid cultivar and the right of the breeders, we successfully develop a novel method by the introduction of foreign DNA sequence (27bp) as molecular marker via BioWare low pressure gene gun into Mormodes lawrence and Zygopetalum mackayi. Histochemical GUS transient expression was obtained from aleurone layer and embryo of Zea mays using BioWare low pressure gene gun with acceleration pressure of 50psi. This is the first report on successful transfer into plant tissue using BioWare low pressure gene gun.

本研究的目的为利用核苷酸排列组合之多样性，设计一段27个碱基对序列来代表品种所有者注册资料，经由国人自行研发之生物镓低压基因枪，利用50psi的氦气压力，将设计好DNA序列标志转殖至妖精兰与轭瓣兰品种，使其实生或分生之子代，皆会具有此注册片段，品种权所有者可以具体以PCR或定序分析确认DNA序列标志，作为保障种源权之认证系统。

The diversity of microbial community in acid mine drainage is at low level and samples with similar biogeochemical properties have similar microbial communities.

在古矿井区域酸性矿坑水中微生物群落的多样性很低，生物地球化学特性相近的酸性矿坑水由具有相近的微生物群落组成。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
