查询词典 phylogenic

The molecular phylogeny and phylogenic differentiation of eight species of the genus Ostrinia from China were studied based on mtDNA-CO Ⅱ gene sequences.

本文利用mtDNA-COⅡ基因序列，研究了中国分布秆野螟属Ostrinta 8种螟虫的分子系统学和系统分化。

In the most rigorous test yet of this hypothesis, Shai Meiri of Imperial College, London, and his colleagues looked at 1,184 island–mainland population pairs both separately and in an analysis that took into account their phylogenic relationships.

伦敦皇家学院的夏末力及其同事们严密证实了这个假说，他们对1，184对大陆人口做了对比分析总结系统发生关系。

Thus, the molecular techniques are becoming more popular in the differentiation of Microcystis.16S rDNA, 16S-23S rDNA ITS and PC-IGS have been used in phylogenic classification of Microcystis, they are common molecular markers of taxonomic researches and a number of results have been carried out.

利用分子生物学技术鉴定微囊藻的种属具有快速而且可靠的优势，因此已成为了分类研究的新趋势。16S rDNA、16S-23S rDNA ITS、PC-IGS等基因序列在微囊藻的分子系统发育方面已有一些研究结果，是目前分类学研究较常用的分子标记，但各自仍存在了一定的问题。

The UPGMA phylogenic tree and principal components analysis result showed that the populations of C. japonica in Japan were closer to C. pauciflora and C. heterosepala than the populations in China did.

主成分分析结果与聚类结果一致，表明C.japonica的日本居群较中国居群与C.heterosepala和C.pauciflora的遗传距离更近，其中本州居群和四国居群居群与它们的关系最近。

NJ and ME algorithms were used to construct phylogenic trees of the sequences, which amplified by gyrB and rpoCl genes.

另外，从结果可以看出两种基因对于区分铜绿微囊藻和惠氏微囊藻均表现出较好的解析度。

The result was consistent with morphology of Pleuronectiformes on the whole.In the topology founded,Scophthalmus maximus and Solea senegalensis formed an independent branch each other and showed far relationship with species of Bothidae and Pleuronectidae,the phylogenic position of Solea senegalensis is accorded with the reported result of analysis made by mitochondrial genome.

运用PAUP软件对15种鲽形目鱼类与另外7种不同种属鱼类进行了分子系统进化树分析，结果与根据传统的形态学和生化特征分类进化地位基本一致，在15种鲽形目鱼类中只有大菱鲆和塞内加尔鳎各自单独形成一个分支且与鲆科和鲽科鱼类相距较远，其中塞内加尔鳎等种类的分类地位与根据线粒体DNA序列分析的系统发生模式基本吻合。

Phylogenic analysis based on entire S1 gene sequences showed that majority isolates clustered together with the close phylogenetic relationships. Therefore, we researched pathogenicity of the selected isolate IBV CK/CH/LDL/05II in this group, Pathogenic study showed that this virus caused 100% morbidity and 54.5% mortality to 15-day-old specific-pathogen-free.The kidneys from the dead chickens showed the predominant gross lesions which were pale, mottled, and swollen. The renal tubules and ureters were distended with excess urates.

经S1基因系统进化树分析发现，本实验所分离的大多数IBV毒株(8/12)分布于同一基因进化群内，并且亲缘关系较近，因此，我们对此群中IBV毒株CK/CH/LDL/05II的致病性进行研究，以10~(5.5)×EID_(50)/0.1ml的病毒接种15日龄的SPF雏鸡，鸡群发病率为22/22(100%)，死亡率为12/22(54.5%)，死亡鸡以肾脏肿大、苍白、外观呈现典型的&花斑肾&，肾小管和输尿管扩张并且有尿酸盐沉积为主要病理变化。

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。
