According to the domain organization, the GGDEF-EAL containing proteins (pfam database, version 17.0) were classified into A and B types. Six hundreds and five of the 621 proteins were in A type, which was also found in the ancient bacteria Aquifex aeolicus VF5 suggesting that this is the ancestor of the GGDEF-EAL proteins. Phylogenetic analysis of GGDEF- and EAL- containing proteins in the genome of V. vulnificus YJ016 revealed that GGDEF-EAL proteins were clustered. Comparative analysis of domain organization of the clads in the EAL tree allowed identification of several duplication events. The results indicated that most of the GGDEF- and EAL- containing proteins arised by gene duplication.

根据pfam资料库(Version 17.0)，我们整理同时拥有GGDEF和EAL功能性区域的蛋白质，这些蛋白质可以被区分成两种型态，在总数621个GGDEF-EAL中有高达606个是A型态，而且它在古老的细菌Aquifex aeolicus VF5的基因体中也能找到，因此我们推测它可能是GGDEF-EAL的袓先，藉由分析创伤弧菌中所包含之GGDEF和EAL的演化关系，大部份的GGDEF-EAL会群聚在树型相近的位置，进一步比较在EAL树型上有邻近关系的蛋白质序列，根据他们的长度、与所包含的功能区域，我们找到了一些重制的演化痕迹，这样的结果指出，目前看到大多数的GGDEF 和EAL可能都是经过重制产生。

In Genus Culter, genetic distance within species is obviously lower than that between species. And in the phylogenetic trees, all individuals of each species formed a clade. Then the conculsion was that mitochondrial CO1 gene was a good marker in Culter DNA barcoding. The conclusion was the same when the research group turned to Subfamily Cultrinae.

对鲌属物种的DNA条形码研究而言，其种间遗传距离显著地大于种内遗传距离，并且同一物种的不同个体均形成高支持率的单系，说明在鲌属类群中线粒体CO1基因是一个有效的DNA条形码标准基因。

By comparing their sequences with homologues from other plants, it was found that GME genes were highly conserved among plant species, though phylogenetic study showed that all known GMEs could be divided into two distinct groups corresponding to monocots and dicots.

通过逆转录PCR技术从水稻成熟叶片中克隆到两个GME基因的cDNA序列，并与其他植物物种中的GMEs进行比对，结果显示，GME基因在所有植物物种中高度保守，尽管进化树分析表明单子叶植物GMEs和双子叶植物GMEs在进化上相互独立。

Firstly, both cDNAs were isolated from the rice mature leaves using RT-PCR technique. By comparing their sequences with homologues from other plants, it was found that GME genes were highly conserved among plant species, though phylogenetic study showed that all known GMEs could be divided into two distinct groups corresponding to monocots and dicots.

通过逆转录PCR技术从水稻成熟叶片中克隆到两个GME基因的cDNA序列，并与其他植物物种中的GMEs进行比对，结果显示，GME基因在所有植物物种中高度保守，尽管进化树分析表明单子叶植物GMEs和双子叶植物GMEs在进化上相互独立。

Bioinformatics was used to seek the homologous gene of EXT1 in Strongylocentrotus purpuratus which was just discovered and had the correlation to human hereditary multiple exostoses. The sequence, exons, coding protein, physical and chemical characters of EXT1 gene were analyzed. The structure and function of its coding protein were predicted, and the phylogenetic tree for the homologous gene was constructed, which provided certain basis for the future research of human EXT1 gene.

利用生物信息学方法寻找人类遗传多发性外生性骨疣EXT1基因在紫色球海胆中的同源基因，对该基因的序列、外显子信息、编码蛋白及其理化性质进行分析，并预测其编码蛋白的结构与功能，构建其同源基因的系统进化树，旨在为进一步研究人体EXT1基因提供一定的依据。

A phylogenetic tree was reconstructed based on the partial sequences of 16S rDNA and COⅠgenes in eight commercial flatfishes. The parameters of pairwise genetic distance among these flatfishes were calculated.

进一步利用线粒体DNA的16S rDNA、COⅠ基因的部分序列对8种重要海水养殖鱼类的系统进化分析，计算了其种间的遗传距离。

Phylogenetic anlysis shows that AmphiLysC is more related to invertebrate c-type lysozymes than its vertebrate counterparts, and g-type lysozyme is basal to c- and i-type lysozymes, favoring the notion that g-type lysozymes are structurally closest to the lysozyme ancestor.

对不同类型的溶菌酶进行系统进化分析，发现来自不同物种的C型、G型和I型溶菌酶各自聚集成簇，AmphiLysC与无脊椎动物C型溶菌酶聚在一起。

From here, inferring on phylogenetic relationship can be used to further determine the relationship between Taiwan and mainland China's garlics.

As F.graminearum is one of the most important pathogens of wheat head blight in China, 19 strains from cereals were selected for phylogenetic study.

谱系2是我国首次报道的进化群，这一发现完成了谱系2在世界上从南美经尼泊尔向我国传播，进而进入韩国的这样一条传播路径。

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。
