系统发育

We can predict the structure and function of new sequence, and analyze the homologous relationship by aligning sequences and constructing phylogenetic tree.

通过多序列比对和系统发育可以预测新序列的结构和功能，分析序列之间的同源关系。

Immunoblot results indicate the antibody can also cross react with the proteins of other silica-accumulated graminaceous plants, while it does not react with the proteins of dicotyledonous plants. These findings indicate that the homologous proteins of SBP117 are widely existed in the graminaceous plantss. This indicated silica accumulated in higher plants posses the character of systematic development.

免疫印迹检测表明此抗体还能与其它累积硅的禾本科植物硅体中的蛋白发生交叉反应，但不能与双子叶植物蛋白反应，这说明与SBP117相似的硅结合蛋白广泛存在于积累硅的禾本科植物之中，硅在高等植物中的积累具有系统发育上的特征。

The application of the RFLP technique in the plant genetie and breeding were summarized in follwing six aspects: lThe construction of linkage genetic maps; 2The application of RFLP Linkage genetic maps in the graminaceous crops;.3Following the tracks and appraisal of the chromosome or.its fragment analyses of the systemtic development; 4The research of the quantitative trait inherit...

本文介绍了RFLP技术的原理及特点，并从六个方面综述了国内外RFLP技术在植物遗传育种中的应用：（1）连锁遗传图谱的构建；（2）RFLP连锁遗传因在禾本科植物中的应用，（3）跟踪、鉴定染色体或其片段、分析系统发育；（4）数量性状遗传的研究；（5）优良性状及抗性材料的筛选；（6）种质资源遗传多样性的研究。

Objective To study the effect of growth hormone and insulin-like growth factor on development of the immune system in childhood.

目的 研究生长激素和胰岛素样生长因子对小儿免疫系统发育的调节作用及其机制。

Heinrich said that in small children when contacted by Goumao into the interior of bacteria, to stimulate their immune systems mature.

海因里希表示，儿童在很小的时候接触由狗毛带入室内的细菌，能够刺激他们的免疫系统发育成熟。

Further morphological observations were performed on the holotype of Leptobotia zebra and other specimens including formalin-fixed museum specimens and newly collected alcohol-fixed ones.

系统发育分析发现斑纹薄鳅并未和薄鳅属的物种聚在一起，而是和中华沙鳅属物种美丽沙鳅聚在一起形成姐妹群。

The phylogeny of hominoid is still an open question.

有关人猿超科的系统发育仍然存在争议。

In molecular phylogebetic tree constructed, we made the Ka / Ks value pairwise comparison of HMGbox flanking sequences both intra- and inter- Hominoid and the Old World m onkey .

通过构建系统发育树，比较旧大陆猴和人猿超科两个类群内和类群间HMG盒侧翼序列K a/Ks的比率。

The ultrasturcture of the spermatozoon of Hyla chinensis was studied in this paper and its significance on the phylogenesis was roughly inquired.

摘 要 研究了中国雨蛙精子的超微结构，并初步探讨其在系统发育上的意义。

This study implies that it is infeasible to reconstruct phylogeny solely by the comparative genomic data.

这项研究暗示着单独依靠比较基因组学的数据来重建系统发育是不可行的。

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。
