查询词典 phylogenetic development

基于线粒体基因组13个蛋白质编码基因的核苷酸序列及氨基酸序列的联合数据集构建了15种鳞翅目昆虫的系统树，采用BI和ML分析方法建树，所得拓扑结构类似，都显示蚕蛾总科，尺蠖蛾总科和夜蛾总科关系较近，结果与前人研究的结果不完全一致。

In comparison of the NS gene analysis, changes of the amino acid sequences are lesser than those in the HA gene. The phylogenetic analysis of NS gene is not form different linage between B/Taiwan/3143/97 and B/Taiwan/21706/97, and all isolates were closed to each other.

由HA基因序列的比较中发现，新的分离株的突变位置与B/Taiwan/3143/97大部分都类似，但突变点相较之下数目较少；而在演化树的分析中，新的分离株会与B/Taiwan/3143/97聚集，形成一新的群集。

利用传统细菌分类鉴定方法对其形态和生理生化特征进行了研究，发现其与藤黄微球菌的特征相符， 16S rDNA序列分析的结果也表明它与藤黄微球菌的16S rDNA序列的同源性高达99%，因此该菌在系统分类学上属于微球菌属藤黄微球菌。

Don has often been included in Disporum but recent micromorphological, karyological, phytochemical, and molecular phylogenetic studies indicate that separation of the two genera is appropriate.

Don通常被归入Disporum但最新的微形态学、核、植物化学和分子系统学的研究表明把这两个属分开是恰当的。

These individual characters are similar to those of most aquatic plants in monocotyledonous Helodiales and dicotyledonous Nymphaeales, which reflects the phylogenetic relationships of Iris from aquatic plants to xerophil.

这些个体性状与单子叶沼生目和双子叶睡莲目多数水生植物相似，从一定程度上可以反映鸢尾属植物从水生到旱生的系统发生上的关系。

The rate of repetitive sequences was 2.55% and no SINEs, LINEs, LTR anti-transcription elements or DNA transposon elements were found, although one11 microsatellite was found. 2 In the P1 promotor region, sequence homology between the Tibetan sheep and mouflon, goat, cattle and European bison was 99.7%, 94.2%, 85.9% and 86.5%, respectively, while that for exon 1A was 99.0%, 97.0%, 92.7% and 94.6%, respectively. 3 The molecular phylogenetic tree among these species, constructed by the neighborhood joining method based on the sequences of no-coding region of the GHR genes, placed the two Bovinae species on one branch and the three Caprinae species on the other.

在该非编码序列中，重复序列所占比率为2.55%，不存在SINEs、LINEs、LTR类反转录元件和DNA转座子元件，而发现存在一11微卫星位点；(2)在启动子P1区，藏绵羊与摩弗伦羊、山羊、普通牛、欧洲野牛各物种间同源性大小分别为99.7%、94.2%、85.9%、86.5%；而在外显子1A区段，藏绵羊与摩弗伦羊、山羊、普通牛、欧洲野牛各物种间同源性大小分别为 99.0%、97.0%、92.7%、94.6%。
