查询词典 clade

The phylogeny of the genus Machilus was analysed by means of Bayesian Inference of nrDNA ITS sequences . Our results indicated that Machilus is a monophyletic clade within the Persea group, and its persistent and spreading to reflexed tepals on fruit are an important character for its generic delimitation against the related genera Phoebe, Alseodaphne and Persea .

应用nrDNA Internal Transcribed Spacer 序列，使用Bayesian 分析法对樟科润楠属的系统学问题进行了初步探讨，结果表明润楠属在鳄梨属群中本身作为一独立分支，是一个自然的单系类群；由于其花被裂片果期宿存且强烈反转与同产自亚洲的楠属和油丹属存在清晰界线。

The phylogenetic tree indicated that the Trametes group was separated from other groups and most strains of Trametes versicolor formed a single clade with a high percentage support.

该树状图显示，栓菌属类群与其他属类群明显分开，Trametes versicolor聚类到一个高支持率的独立分支。

For years a debate raged in the medical community over whether a person could be reinfected (also known as same clade superinfection) even after developing antibodies.

多年来，一个医学争论一直在进行，到底感染者是否会再感染，甚至在产生抗体后。

The phylogenetic analysis based on the amino acids of invertebrate and vertebrate S19 proteins showed that the amphioxus protein was at the base of a clade of vertebrate S19 proteins, indicating that amphioxus is not only the sister group of extant vertebrates but also the basal lineage of chordates.

另外，AmphiS19与脊椎动物各S19蛋白在氨基酸水平上的相似性几乎是等同的。这些结果表明文昌鱼不仅是脊椎动物的姊妹类群，而且是脊索动物谱系进化过程中的基部类群。

The remaining species form a well-supported clade, which in turn can be divided into smaller groups.

余下的物种形成一个良好的支持分支，这反过来又可以分为较小的团体。

It is a major clade of evolutionary developmental biology or evo-devo.

在拟南芥根部，编码AP2-结构域转录因子的两个PLETHORA基因能维持干细胞的活性。

In CC clade,in which rice is planted in two seasons,C suppressalis has three to four generations per year.

而且，二化螟的遗传分化大致与其在3大地理区域内每年发生的代次相一致。

We used mitochondrial cyt-b gene to conduct phylogenetic reconstruction, nested clade analysis and mismatch distributions of this frog.

我们利用cyt-b基因构建了单元型的系统发生树，进行了巢式统计分析和种群的歧点分布分析。

As the first assembled chromosome from a member of the grass clade and the first non-Arabidopsis plant chromosome reported, it is a very important contribution to plant biology and as such is worthy of publication in Nature.

作为首次发表的来源于谷类作物组装的，非拟南芥植物的完整植物染色体，这篇文章对于植物生物学有着非常重要的贡献，是应当在《自然》杂志上发表的。

It has been put forward that there exists single Ball point and double Ball points on the symmetrical connecting-rod curves of equilateral mechanisms.

从鲍尔点的形成原理出发，分析对称连杆曲线上鲍尔点的产生条件，提出等边机构的对称连杆曲线上有单鲍尔点和双鲍尔点。
