查询词典 phylogenetic development

Molecular phylogenetic analysis showed that the genus Cordyceps was not a natural group, only Neocordyceps of three subgenera of Cordyceps formed a monophyly.

分子系统学分析结果表明，传统形态分类所依据的特征在某种程度上不能反应虫草属的自然进化关系。

With the 39 species nrDNA ITS sequence from Genbank and by using nrDNA ITS sequence information of our study 31 species, a phylogenetic analysis was carried out on 70 species of Paphiopedilum, and then the results have been analyzed with the results from RAPD molecular marker of 30 species, indicated that, we supported Kirasawa's system proposed in 1982 on Paphiopedilum that this genus can be divided into six subgenera.

基于 ITS 序列的数据对兜兰属70个种的研究，结合 RAPD 对于中国兜兰30个种的研究结果进行分析，支持唐沢耕司（1982）所提出的将兜兰属分为6个亚属的观点，其中产于中国的兜兰属植物可以划分为5个亚属；认为巧花兜兰不能并入海伦兜兰中，最多可以作为其变种处理，或者独立成种，隶属于兜兰亚属的 Paphiopedilum 兜兰组；不支持将文山兜兰并入巨瓣兜兰或者同色兜兰中，可以作为是其变种处理，隶属于 Concoloria 组。

The phylogenetic analyses suggested that the YLS of BPH with different virulence belonged to the subphylum Ascornycotina, the class Pyrenomycetes, and had the closest genetic relationship with Hypomyces chrysospermus.

结果显示，褐飞虱3种不同致害性种群体内的YLS同属子囊菌亚门的核菌纲，并与此纲中的Hypomyces chrysospermus亲缘关系相对最近。

Urticae and constituting the phylogenetic tree, we found that they were similar to or completely identical with the wsp gene sequences of some strains of Wolbachia of Ori group in B supergroup.

对序列进行系统发育分析，发现它们全部与B大组Ori组的乳Wolbachia株系十分相近或完全相同。

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。

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。
