Annexin B1 and arthropod formed an independent branch in the species phylogenetic tree; nemathelminth, plant, Ayes and vertebrate formed a branch; pprotozoa, cnidaria, amphibia and chordate formed another branch.

在物种进化上，Annexln B1和节肢动物为1支，新杆线虫、植物、鸟类和脊椎动物为1支，原虫、腔肠动物、两栖类和脊索动物为1支。

The results of phylogenetic analysis indicated that various L-GalDH sequences were clustered into three groups.

系统进化分析结果表明不同来源的L-GalDH基因聚为3类。

After analysis of multiple sequences alignment, phylogenetic tree and similarity of sequences, it was shown that Ac-ASP has similar relation with Am-ASP, and shared high homology with other Hymenopteran and Coleopteran. From above analysis, we firmly suggest Ac-ASP1 and Ac-ASP2 belong to OBPs family and Ac-ASP3 belong to CSPs family.

通过多序列联配、系统发育树及序列相似性分析，Ac-ASP除与西方蜜蜂Am-ASP亲缘关系较近(相似性达到80％以上)外，与其它膜翅目以及鞘翅目的OBPs及CSPs也有一定的亲缘关系(相似性达到30～60％)，且Ac-ASP1和Ac-ASP2应为OBPs，Ac-ASP3则应为CSPs； 4。

While the divergence of homologous genes from different species is in well congruent with phylogenetic relationship of those species.

不同物种的同一种基因的聚类关系能较好地反映物种间的系统发育关系。

The origin analysis on the source of hosts and terrains was carried out on the base of homology tree and phylogenetic tree founded in 19 isolates on their CP gene nucleotide sequences. The result showed that the gene types and clusters of Cucumber green mottle mosaic virus were not obviously related to the two factors.

对包括该分离物在内的19个CP基因核苷酸序列进行同源性比较和系统进化树构建，并结合寄主来源及地域来源进行LHP的起源分析，结果表明黄瓜绿斑驳花叶病毒不同分离物的序列分群和进化关系与上述两个因素无明显关系。

In this study, we wanted to discuss the consequences and potential of the CO1 gene as a marker for phylogenetic reconstruction and DNA barcoding of this endemic cyprinid group.

本研究将验证线粒体CO1基因在东亚特有类群中进行DNA条形码研究的可行性，并且拟基于线粒体CO1基因序列探讨东亚特有鲤科鱼类的系统发育关系。

To assess support for the monophyly of East Asian endemic cyprinid taxa, we used the mitochondrial CO1 gene sequences for phylogenetic reconstruction of the family Cyprinidae.

2为探讨东亚特有鲤科类群的单系性以及其内部物种的系统发育关系，本研究将实验获得的线粒体CO1基因序列与GenBank中下载的序列相结合构建鲤科鱼类的系统发育树。

Although the monophyly of Cultrins was strong supported, the relationships of each groups in East Asian endemic Cyprinid taxa were not well resolved. The result indicated that the mitochondrial CO1 gene sequence provided less phylogenetic information to resolve the relationship of this East Aisan cyprinid group.

但基于线粒体CO1基因序列的系统发育分析，东亚特有类群内部各分类单元的相互关系依然没有得到很好的解决，结果表明线粒体CO1基因无法提供足够的系统发育信息来解决东亚特有鲤科鱼类内部类群的系统发育关系。

Comparisons of mitochondrial gene arrangements of decapod suggested that rearrangement of the four gene-block found in Eriocheir is informative for high level phylogenetic study of decapod.

十足目动物线粒体基因排列顺序的比较研究显示，在绒螯蟹中发现的4基因块的重排，对十足目高级阶元的系统发生研究是有用的信息。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
