查询词典 phylogenetic

The polymorphic profile could reflect the polymorphism of the taxa and related taxa. RAPD can provide some molecular proof for Bryaceae's phylogeny. There is no need to study deeply on Phylogenetic relationships of Bryaceae.

可见RAPD可以为真藓科Bryaceae植物的系统发育研究提供分子证据，真藓科Bryaceae植物的系统发育关系有待进一步研究。

The placement of Pohlia, the status of Rhodobryum genera and the phylogenetic relationship of several generas within Bryaceae are conflictive. In this study, the optimum random amplified polymorphic DNA reaction system for Bryaceae was built, then the RAPD profile of Bryaceae was construct.

在真藓科Bryaceae中，丝瓜藓属Pohlia的位置、大叶藓属Rhodobryum属的地位和真藓科Bryaceae内几个属的系统排列关系一直存在争议。

The result from phylogenetic trees created respectively by MP, NJ and UPGMA indicates that Bryaceae and Bryum are not monophyletic. The definition of some groups of Bryaceae and Bryum is doubtful in traditional classification based on morphological data. The analyses approves that Pohlia is more closely related to Mniaceae than Bryaceae, which supports placement of Pohlia in Mniaceae from Bryaceae based on DNA sequence data.

系统发育分析的结果显示：丝瓜藓属Pohlia更接近于提灯藓科Mniaceae而远离真藓科Bryaceae的类群，支持Cox等分子序列证据将丝瓜藓属Pohlia放在提灯藓科Mniaceae的安排；大叶藓属Rhodobryum与真藓属Bryum作为姊妹群存在，不支持Ochi将其作为真藓属Bryum内一个亚属的安排。

Bryozoa is an important group of metazoan animals which has received relatively little attention regarding their origin, phylogenetic relationship with other metazoan phyla and its internal phylogeny.

苔藓动物是后生动物中的一个重要类群。然而，和其它主要后生动物类群相比，长期以来对它的系统学研究却相对滞后。其起源、系统发生地位以及与其它后生动物门类之间、其内部各高级分类群间的谱系发生关系一直存在争议。

According to the phylogenetic analyses, the homologous genes of Buxus belong to their expected clades, showing a position near the base of core eudicots.

另外，根据谱系分析的结果，鉴定出的黄杨花部基因分别属於ABCE 同的基因系群内，位於真双子植物之中。

Parvifolia was 642bp by cloning PCR production and sequencing, and its phylogenetic information might facilitate to provide the direct molecular evidence to clarify its origion and evolution for Buxus sinica var. parvifolia.

珍珠黄杨ITS片段克隆测序后获得的序列长度为642bp，其系统学信息将为珍珠黄杨的起源进化提供有力的分子水平证据。

Multiple sequence alignment and phylogenetic analysis of CVX-NTU and other completely sequenced potexviruses demonstrated that CVX-NTU has a close relationship with potexviruses infecting plants in the family Cactaceae.

将CVX-NTU病毒分离株各个ORF与其它已知序列的同属病毒作胺基酸序列比对及类缘分析，结果显示感染仙人掌科的potexvirus都属同一个分群中，显示彼此的类缘关系较密切。

Therefore, NTU isolate is considered as a new CVX isolate and thus designated as CVX-NTU. Multiple sequence alignment and phylogenetic analysis of CVX-NTU and other completely sequenced potexviruses demonstrated that CVX-NTU has a close relationship with potexviruses infecting plants in the family Cactaceae.

当完成NTU全长度核酸序列的解序工作后，将NTU的各个基因转译成胺基酸序列，与已发表的CVX-Hu胺基酸序列作比对，发现两者的RdRP与CP相同度分别达85%和86%，故认定为一新发现之CVX分离株，并取名为CVX-NTU。

In this study, the spore germination of Lasiosphaera fenzlii and Calvatia gigantea were studied,the optimum fermented conditions were investigated.The anti-inflammation and antibacterial were carried out using the fermentative products. The results were as follows: Molecular identification techniques using DNA showed that samples collected are Lasiosphaera fenzlii and Calvatia gigantean.Using analysis of Internal transcribed sequence and construct phylogenetic trees,results showede that Lasiosphaera fenzlii and Calvatia gigantean have close relationship.

本研究以大秃马勃Calvatia gigantea和脱皮马勃Lasiosphaera fenzlii为研究材料，进行了马勃孢子的萌发条件研究，并以大秃马勃Calvatia gigantea菌种为研究材料，进行了优化培养和发酵液药理实验的初步研究，结果如下：采用DNA分子鉴定技术对采集的样品进行了分子鉴定，结果为大秃马勃Calvatia gigantea和脱皮马勃Lasiosphaera fenzlii。

The phylogenetic relationships of Calycanthaceae were investigated by means of molecular systematics, which was based on three DNA sequences from three genomes, including chloroplast DNA trnL-F, nuclear 18S ribosomal DNA, and mitochondrial matR gene.

本文选取来自于三个基因组—核基因组、线粒体基因组和叶绿体基因组的3个DNA序列片段，对蜡梅科的系统发育进行重建，主要探讨了蜡梅科的系统位置和属间系统演化关系。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
