查询词典 phylogenetic

In biological systematics as a whole, phylogenetic analyses have become essential in researching the evolutionary tree of life.

从生物分类学总体上看，在对生命进化树的研究中，系统发生分析已成为必不可少的要素。

Spermatogenesis of teleost and its prospective application in the study of phylogenetic development.

硬骨鱼类精子发生及其在系统演化研究中的应用前景

Phylogenetic trees including all β-actin cds or 3 UTR of teleost fishes were constructed respectively, which indicate that teleost β-actin can be classified into four types, and the β-actin cloned from the rice field eel here is type II.

基于目前已知的全部鱼类的β-actin cds和3'UTR，我们分别构建了进化树。结果它们都一致支持将鱼类的β-actin基因划分为四类。黄鳝的β-actin基因属于其中的第二类。

We have amplified partial sequences of MADS1, MOC1 (MONOCULM1), and TB1 (teosinte branched 1) genes from 42 bamboo species. Molecular and phylogenetic analyses were performed and the application to bamboo evolution and classification were assessed.

本研究采用PCR扩增的方法从16属42种竹类植物中扩增到了MADS1、MOC1(MONOCULM1)和TB1(teosinte branched1)部分基因序列，并对这些序列进行了详尽的序列分析与分子进化分析，着重探讨了它们在竹类植物系统进化与分类中的应用。

A tree diagram used to illustrate phylogenetic relationships .

表示动植物史关系的一种树形。

表示动植物种类史关系的一种树形图表。

Although ubiquitous, the taxonomy and phylogenetic relationships of fish trypanosome s are uncertain.

在自然条件下，锥虫经吸血水蛭传播广泛寄生于各种海水和淡水鱼类，但鱼类锥虫的分类和系统发育关系并不清楚。

Despite early morphological descriptions of the Mexican trout, many populations remain completely undescribed and their phylogenetic relationships have only recently been analyzed using modern molecular genetic techniques.

尽管墨西哥鳟早期形态描述，许多民众仍完全过的亲缘关系和它们刚被运用现代分子遗传学分析技术。

Phylogenetic analysis of 23 HEV71 isolates showed that during the first half of 2005, viruses belonging to 3 subgenogroups, C1, C4, and a previously undescribed subgenogroup, C5, cocirculated in southern Vietnam.

对分离的23个肠病毒71型病毒株做物种族谱种系分析显示，在2005上半年，流行的肠病毒71型病毒株基因型属於3个亚型， C1 、C4、，和一先前未被发现的C5新亚型，在越南南部流行。

The primers of ITS-1 and ITS-2 proved to be very universal in a large variety of mollusc species. The potential uses of the 2 sequences for genetic variation studies and phylogenetic research in scallop species were discussed too.

这两个变异性较大的序列在扇贝种群中应用潜力很大，可广泛用于种内群体间遗传变异研究、种质鉴别及系统学研究。

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。
