查询词典 phylogenetic

From the phylogenetic tree constructed for IGF-I, the homology was as high as 95%, which revealed the relative relation between them was more closely than with others and give molecular biology support for the resolution of position and classification of lesser panda.

利用IGF-Ⅰ基因构建的进化树上，大熊猫和小熊猫此基因的同源性达到95%，并且显示小熊猫与大熊猫的亲缘关系与其它哺乳动物相比要近的多，为大熊猫及小熊猫的分类学提供了分子生物学的依据，但这样的结果也许与IGF-Ⅰ在物种间的高度保守性有关，我们认为，对于大小熊猫是否同属一科还需要进一步的研究。

To obtain full-length FKN nucleotide sequences of homonids, including human, chimpanzee, gorilla, orangutan and gibbon and Old World Monkeys, including macaque and leaf monkey and make phylogenetic analysis.

测定人猿超科（人、黑猩猩、大猩猩、红毛猩猩和长臂猿）和旧大陆猴7种高等灵长类FKN全基因序列，探讨其系统进化分析。

The phylogenetic tree was constructed using maximum evolution approach in Mega. The negative selection sites were analyzed by using Datamonkey. There is an apparent 30 bp nucleotides deletion mutation in homonids FKN comparing to that of Old World Monkeys besides other point mutations. Homology of nucleotide sequence between human and chimpanzee, gorilla, orangutan, gibbon, macaque and leaf monkey is 99.2%、98.4%、98.1%、96.5%、95.9% and 93.8% respectively. Homology of amino acid sequence of them is 98.5%、98.0%、97.7%、94.7%、93.7% and 90.5% respectively.

序列分析发现人猿超科较旧大陆猴FKN基因除了有散在的点突变外，还有一明显的30bp的核苷酸缺失突变；人FKN基因序列与黑猩猩、大猩猩、红毛猩猩、长臂猿、猕猴和叶猴的同源性分别是99.2%、98.4%、98.1%、96.5%、95.9%和93.8%，由此推导的氨基酸序列同源性分别是98.5%、98.0%、97.7%、94.7%、93.7%和90.5%；FKN基因进化树表明人与黑猩猩关系更近，FKN基因进化和通常认为的物种进化一致；Datamonkey分析结果显示FKN存在3个负选择位点53Q、84D、239N。

Our previous molecular cloning of snakehead fish GTH cDNAs revealed that the third cysteine residues is absent in shfFSH-β; instead, a positionally shifted cysteine is present at the N-terminus, as found in some phylogenetic related fish.

本研究已选殖鳢鱼脑下垂体GTH cDNAs，发现FSH-β次单元之第三个半胱胺酸并不存在，取而代之在N端有一多的半胱胺酸，由进一步资料分析发现鳢鱼相近鱼种亦有此特性。

The results of dendrogam were consistent with the previous conclusion of morphologic classification and cytotaxonomy, and suggested RAPD was suitable for analysis of phylogenetic relationships among species of Oxya .

聚类图所呈现的种间关系与传统的形态及细胞分类学结果基本一致，5种稻蝗亲缘关系的远近程度得以清楚显示，说明RAPD技术在稻蝗属种间分子系统学研究中具有很好的适用性。

Phylogenetic analyses revealed that there were two mtDNA lineages identified in five goat breeds including Angora goat, Shandonglaiwu black goat, Lubei white goat, Taihang goat and Wuzhumuqin goat. Population genetic structure and population expansion were carried out.

利用线粒体DNA分析安哥拉山羊、山东莱芜黑山羊、鲁北白山羊、太行山羊及乌珠穆沁绒山羊，揭示这5个山羊品种分成A和C 2个支系，并进行了群体结构和群体扩张分析。

Here, we examined the genetic diversity and phylogeographic structure of domestic goats by determining mitochondrial DNA and microsatellite DNA. The genetic diversity of five goat breeds including Angora goat, Shandonglaiwu black goat, Hanshan white goat, Taihang goat and Wuzhumuqin goat was surveyed using twenty-five microsatellite loci, The UPGMA phylogenetic trees constructed with the Dcoa genetic distances between the five goat breeds supported a closer relationship between Hanshan White goat and Wuzhumuqin goat.

利用微卫星和线粒体DNA分析山羊的遗传多样性及系统进化关系，用25个微卫星位点分析了安哥拉山羊、山东莱芜黑山羊、罕山白绒山羊、太行山羊及乌珠穆沁绒山羊这5个山羊品种的遗传多样性，利用共祖遗传距离的UPGMA聚类表明遗传距离和地理距离是一致的，如内蒙的罕山白绒山羊和乌珠穆沁绒山羊聚到一起。
