查询词典 phylogenetic development

Topological structure of the molecular phylogenetic tree, constructed by 16S rRNA gene with Neighbor-Joining method, revealed that all species of Helice from Sesarmidae and two species of Hemigrapsus from Varunidae were clustered into one branch, two species of Sesarma from Sesarmidae were clustered into another one, Grapsus albolineatus from Grapsidae and Plagusia tuberculata from Plagusiidae were formed one absolute branch respectively. The molecular analysis showed that the genus Helice indeed must be considered to be Varunidae, because it formed a monophyletic group with the genus Hemigrapsus yet not the Sesarmidae.

而采用NJ法构建的系统进化树的拓扑结构也显示，所有的厚蟹与属于弓蟹科的肉球近方蟹和绒螯近方蟹聚为一支；属于相手蟹科的2种相手蟹聚为一支；属于方蟹科的白纹方蟹和属于斜纹蟹科的瘤突斜纹蟹又各自成为一支。

Codon partition schemes were compared in phylogenetic analyses at subfamily level for Gyrinidae and at family level for Hydradephaga based on partial mitochondrial COⅠ gene sequences.

利用PAUP和MrBayes软件，对线粒体COⅠ基因序列3个密码子位置的数据模块分别进行了豉甲科和水生肉食亚目在亚科或科水平上的系统发育学分析，结果表明第二密码子数据模块获得了理想的分析结果。

The result of Neighbor-joining molecular phylogenetic tree also indicated that the eggs and the Japanese halfbeak were assembled at the same embranchment, they shared one haplotype, but the eggs were assembled at different embranchments with the other species of Beloniformes so the fish eggs were alienated from them.

NJ分子系统树的聚类结果也显示鱼卵与沙氏下鱵鱼序列聚为一支，他们共享一个单倍型，而与其它颌针鱼目鱼类序列分为两大支，其亲缘关系较远。

The phylogenetic trees of Hamamelidaceae sensu lato were constructed based on the sequences of nrDNA ITS of 49 species, 23 genera, 4 subfamilies.

测定和分析了金缕梅科6亚科、23属，49种植物的rDNA ITS区序列，构建其分子系统树。

The rbcL gene sequences of six species representing five subfamilies of the Hamamelidaceae and the Platanaceae were determined and used in the phylogenetic analysis on the "lower" Hamamelidae sensu Endress (1989) and its allies newly suggested.

测定了悬铃木科和金缕梅科5个亚科的6个代表种的rbcL基因序列，对低等金缕梅类植物及新近提出的相关类群进行了分子系统发育分析，获得4个最简约树。简约树步长为893，其CI值和RI值分别为0.558和0.591。

The newly collected DNA sequence data were analyzed with data collected in the previous studies involving species representing all the above families but the African Myrothamnaceae to address the phylogenetic questions of the"lower"Hamamelidae and the core family Hamamelidaceae.

主要结论包括：传统低等金缕梅类是一个复系类群；金缕梅科也是一个复系类群；ITS序列分析支持将连香树科包含在金缕梅科内，但是，rbcL资料和matK资料不支持将连香树科包含在金缕梅科内。

Finally, the phylogenetic relationship of taxa with complete mitochondrial genome from Hexapoda was reconstructed by concatenated amino-acid sequences of 12 proteins downloaded from GenBank.

通过结合克隆测序方法，降低了实验难度，提高了该策略的通用性和稳定性，从而建立起一套快速、精确地进行昆虫全线粒体基因组测序的实验体系。

A parallel trend with a phylogenetic history is the appearance of more and more histologically differentiated areas of the cerebral cortex.

和种系发展史平行的一项趋势是越来越多组织学上被分化的大脑皮质区域之出现。

系统发育树显示朝鲜碱茅与大麦、小麦遗传距离最近，跨膜结构与亚细胞定位表明为过氧化物体APX。

Phylogenetic analysis indicated that the deduced amino-acid sequences of BH1-BH4 genes were more closely related to B-hordeins from cultivated barley (Hordeum vulgare L.) than to any other prolamins from wild barley and Aegilops tauschii.

系统分析表明：它们推断的氨基酸序列与栽培大麦中的B组醇溶蛋白具有较高的相关性，与野生大麦和山羊草属的醇溶谷蛋白相似性较低。
