如何挖掘并利用其中所包含的系统发育信息成为近年来系统发育学的研究热点。

In order to demonstrate its validity,we cormtrcted a phylogenetic hee at last.

为了说明此方法的可靠性，最后对多个物种DNA序列作了相似性分析。

It is a relational database designed to manage and explore information on phylogenetic relationships.

The successive start-up of genome project in recent years has far-reaching impact on present phylogenetic studies.

生物基因组计划的相继启动对系统发育学研究的发展产生了深远影响。

Thus, a phylogenetic tree is based on a hypothesis of the order in which evolutionary events are assumed to have occurred.

因此，系统树是基于对进化事件发生顺序的假设。

Furthermore, phylogenetic analysis also indicated that all the sequences from the same species were clustered to one group.

系统发育分析发现，来源于同一种内的2条序列都被聚为一个类群。

The ITS sequences contain many variable sites and phylogenetical informative sites among related species of genus Vigna and phylogenetic relationships among species could be established succesfully.

美洲来源的聚为一类，它们的遗传距离较远，大多在20％左右，遗传多样性较高，位于系统树的最基部，可能为较原始起源的种。

Phylogenetic analysis showed that the proteobacteria were the dominant group both in the sediments and waters,γ-proteobacteria and δ-proteobacteria were dominant in the sediments,α-proteobacteria were dominant in the water. However, all subphyla of proteobacteria presented phylogenetical divergence at the two sites.

各站位中主要为变形菌门，沉积物中γ-Proteobacteria和δ-Proteobacteria亚门占优势，水中则以α-Proteobacteria亚门占优势，但各亚门微生物在两个站位中存在明显系统发育学分歧。

Mitochondrial gene fragments of COⅠ and Cyt b of 24 species in the subfamily Pierinae and Coliadinae were amplified and sequenced. Combing these with the homologous sequences of 2 species from GenBank and using 2 species of the Satyridae as the outgroups, the molecular phylogenetic trees of these groups were reconstructed with neighbor-joining and bayesian inference methods.

测定了粉蝶科的粉蝶亚科和黄粉蝶亚科14属共24种线粒体COⅠ和Cyt b基因部分序列，并从GenBank中下载了2种粉蝶的同源序列，以眼蝶科的2个物种为外类群，运用NJ法、贝叶斯法分别重建了分子系统树，探讨了它们的系统发生关系。

Chromosome evolution: x= 11 occurred in most genera of Komarovieae through Selineae; other basic chromosome number originated multiple times independently in the subfamily Apioideae; For Pleurospermum and Pimpinella, the basic chromosome number of each coincide with their phylogenetic placement.

从性状演化图上看，整个芹亚科的染色体祖先状态可能为 x= 11或者 x= 6，而且亚科内的大多数类群均保持了 x= 11这一祖征；对于其它基数，一般在芹亚科内多次独立起源，构成各自的自征或者共有衍征；对于多系类群，如棱子芹属和茴芹属，染色体分析的结果很好的支持了他们各自的系统位置。

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。
