查询词典 phylogenetic

The phylogenetic analysis based on the sequences in this region indicated that the y-type HMW glutenin subunits of Agropyron elongatum species were different from other subunits, whereas the x-type subunits of them were most closely related to that from the B genome.

推测四倍体长穗偃麦草中的E1基因组可能起源于二倍体的E基因组。与来自小麦族的A、B、D和G基因组部分亚基基因的启动子序列比较表明，小麦族的这一区域在进化上是相当保守的，不同基因组来源的序列同源性都在90%以上。

本文就近年来国内外有关被子植物核糖体DNA中的内转录间隔区序列在植物属内、近缘属间乃至科内系统发育研究中的应用，结合作者在中国姜科山姜属 AlpiniaRoxb 。

The vertebrate TSHβ protein sequences had been used to construct Neighbor-joining and Maximum parsimony phylogenetic tree. As analyzed, Andrias davidianus derived from amphibia firstly, which could reflect its original evolutionary status.

采用邻接法和最大简约法对部分脊椎动物TSHβ氨基酸序列构建分子系统树，结果显示有尾目大鲵为两栖动物中较早分化的一支，表明其进化地位较原始。

In addition, the reconstructed phylogenetic tree based on cDNA and DNA sequences encoding C-terminal non-repetitive region of MaSp1 (Major ampullate spidroin-1) also showed that Deinopoidea and Araneoidea are not sister groups.

另外，依据编码大壶状腺丝蛋白-1(MaSp1)C末端非重复氨基酸序列区段的核酸序列重建的系统发生树也证实圆网蛛类并非单系发生。

The comparison of sequences showed that the determined sequence was most similar to those in GenBank (AF016546)(similarity level, 97.9%), Phylogenetic analysis indicated that the resulting sequence was more similar to those of Mycoplasma spp.(homo!ogy level, about 70%), but was farther from Anaplasma spp.( homology level, about 50%).

系统发育分析表明，所测序列与支原体属病原代表种的序列接近，同源性约为70%，而与无浆体科病原代表种的序列相差较远，同源性约为50%。

There was high level of confidence on anopheline phylogenetic relationship reconstructed by combining nuclear genes with mitochondrial genes.

该文还介绍了建立在基因组计划基础上的全新学科——系统发育基因组学。

In this study, we discussed the phylogenetic relationships in the Anura groups with the sequences of the 12 proteins encoded in the H-strand and 22 tRNAs of mtDNA from 21 species from GenBank. They all indicated that Anura were divided into the Archaeobatrachia and the Neobatrachia,these results supported the monophyletic origin of Anura.

结合饰纹姬蛙和金线蛙的mtDNA以及GenBank上公布的共21种无尾目的线粒体基因组，本文基于编码重链12个蛋白质的基因和编码22个tRNA的基因分别构建了MP系统树，分析了21种无尾目动物的亲缘关系，结果都显示将无尾目分为两大群，支持无尾目的单系起源。

In Anura, the phylogenetic relationships among the main lineages remained largely debated.

现存两栖纲分为三个目。

The results of the phylogenetic cladograms indicated that Apanteles adoxophyesi Minamikaws and Apanteles angaleti Muesebeck are monophyletic group, Apanteles adoxophyesi Minamikaws % Apanteles angaleti Muesebeck and the remain 8 species make up a monophyletic group or paraphyletic group.

支序系统学研究结果证明安氏绒茧蜂Apanteles angaleti Muesebeck和茶小卷蛾绒茧蜂Apanteles adoxophyesi Minamikawa存在着亲缘关系，并形成单系群，与其它几种绒茧蜂形成姊妹群关系或并系群关系。

Biogeography: according to the distribution and phylogenetic placement of endemic genera, Yunnan and SichuanProvinces of KangdianAncientLand are probable the secondary evolutionary centers for Chinese Apiaceae.

根据各特有属在伞形科中的系统学位置以及地理分布状况，我们推测，地处康滇古陆的云南和四川很可能是中国伞形科植物的次生演化中心。

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。
