Vexillifer and Neophocaena phocaenoides is 15.03%(49/326bp). Two phylogenetic trees, constructed by using sequence data, suggest that Lipotes vexillifer does not share a direct common ancestor with Inia geoffrensis, thus provide molecular evidence in favor of the establishment of family Lipotidae; extant river dolphins might be a group ofes with

系统发育分析结果表明：白暨豚与亚河豚没有直接共同的祖先，从而为白暨豚科的建立提供了有利的分子证据；现存的淡水豚类可能仅是外形上相似的物种群，Muizon1984；1988a

This ecological transition is concordant with the independent phylogenetic analysis and the information from preserved integumentary structures

Using Parantica aglea and Euploea core as the outgroups, the phylogenetic trees of the Nymphalidae taxa in this study were reconstructed with and Bayesian methods based on 16S rDNA, 12S rDNA and their combined sequences. The results showed that the Nymphalinae was not monophyletic; the Junonia should be classified into Hypolimni; the Apaturinae, Byblinae and Nymphalinae were closely related to each other; the Pseudergolinae and Byblinae should be separated from Limenitinae.

分子系统树显示：蛱蝶亚科并非单系群，蛱蝶族中眼蛱蝶属应移入斑蛱蝶族；豹蛱蝶亚科为单系发生；闪蛱蝶和苾蛱蝶亚科与蛱蝶亚科具有较近的系统关系；支持将秀蛱蝶和苾蛱蝶亚科从线蛱蝶亚科中分离出来。

Based on comparison of the chloroplast genomes, the estimated time of divergence between the two populations is consistent with the emergence time of the Kra Isthmus. However, ancient and recent gene flow obscures the phylogenetic relationships between eastern and western haplotypes.

经由单套型在亲缘分析结果显示，在地峡东、西两岸的细蕊红树族群无法呈现良好的解析力，显示古地质事件造成的族群扩张和近代海流造成的长距离基因交流导致此结果。

Through PCR and sequencing, a fragement sequence with lamin gene feature was obtained. It was of of transcriptional activity. In addition, we also cloned and identified giardial DNA topoisomerase gene.Our phylogenetic analysis showed that although Giardia diverged early but not first, thus, it is not as primitive as thought before.

然后进行了核纤层蛋白基因的扩增和鉴定，获得了一个具有明显核纤层蛋白基因特征的基因序列片段，并证明它是表达的且不具内含子；此外还克隆鉴定了作为核骨架重要成分的DNA拓扑异构酶II的基因；在此基础上结合已报导的不同进化地位生物上的数据进行了分子系统学分析，结果显示贾第虫虽然分支较早，但不象过去所认为的那么原始。

The distribution of triterpenoidal saponins in the plants of Ladizabalaceae suggests the phylogenetic relation between Lardizabalaceae and Ranunculoideae of Ranunculaceae.

齐墩果烷型三萜皂甙不仅提示木通科与毛茛科的毛茛亚科的系统联系，而且甙元骨架的氧化水平与科内各属的系统进化也有一定的相关性。

In this paper, we made a brief introduction to the significance of Bayesian inference in the molecular evolution and phylogenetic reconstruction, and its application in the molecular phylogeny of Liliales.

本文简要介绍了贝叶斯推论原理及其在分子进化和系统发育研究中的重要性，并使用该方法对百合目主要类群的系统发育关系进行了重建。

The amino acids sequences alignment confirmed that 145 LRR stucture was highly conserved in all aligned PGIP sequences. The results of phylogenetic analysis showed that BoPGIP1 and PGIP from Brassica napus and Arabidopsis thaliana clustered together firstly, and then came from Gossypium barbadense, Lycopersicon esculentum and Phaseolus vulgaris in turn. The clustering results basically accorded with morphological classification system.

将BoPGIP1氨基酸序列与数据库中的其他植物PGIP进行同源序列比对，构建系统进化树，发现所比对基因都含有LRR结构，在145位点的LRR结构域在所有物种中极其保守；系统树显示，该序列最先与甘蓝型油菜和拟南芥聚类，其次和棉花、番茄和豆科作物的PGIP聚类，基本符合按形态特征分类的亲缘关系。

The Magnoliaceae plants not only have scientific value in study on the origination and system phylogenetic evolution of angiosperm, but also are important components to sustain forest's ecosystem equilibrium and conserve biodiversity.

木兰科植物不仅在研究被子植物起源和系统发育进化中有重要的科学价值，而且在维持森林生态系统平衡和生物多样性保护中也起着重要作用。

And the phylogenetic tree shows that it indeed far from its near species, and belongs to a different branch with the P. mahaleb L..

的pgip基因关系较近，而与寿星桃(P.persica L.var.densa Makino)、桃栽培品种'久保'P.persica

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。
