The 16S rDNA sequence of the 4 strains were aligned with the 16S rDNA sequences of other species in genus Burkholderia,and the polygenetic tree was produced by using a Clustal V and treeview software.The results showed that P.cocovenenans subsp.farinofermentans was in a high homology with Burkholderia gladioli and Burkholderia cocovenenans, and they formed an independent phylogenetic clustal of genus Burkholderia.Key words: P.cocovenenans subsp.farinofermentans,16S rDNA sequcence,phylogeny

树状图及不同菌种之间的同源性比值：椰酵假单胞菌(P.cocovenenans subsp.farinofermentans)与唐菖蒲伯克霍尔德氏菌、椰毒伯克霍尔德氏菌的亲缘关系非常近，与其它菌种的亲缘关系相对较远，椰酵假单胞菌、唐菖蒲伯克霍尔德氏菌和椰毒伯克霍尔德氏菌可归属于一个独立的系统发育系。

The Lyb genes were novel members of Y-box gene family containing a conserved cold-shock domain with two RNA binding motifs (RNP-1 and RNP-2). Moreover, phylogenetic analysis revealed that there was only one type of Y-box gene before the emergence of gnathostomata. By contrast, the Y-box gene were divided into three groups, YB1, YB2, and CSDA during evolution of jawed vertebrates.

此外， 从Swiss-Prot下载了经实验验证过的Y-box蛋白序列数据，结合实验克隆得到的Lyb基因所编码的氨基酸序列构建系统发育树，发现Y-box基因在有颌类出现以前只有一种类型，有颌类出现以后， Y-box基因分化成YB1、YB2和CSDA三种类型。

Phylogenetic analysis based on gyrB gene is consistent with those of 16S rDNA tree and provided a better discrimination within the species of Gordonia compared to 16S rRNA gene. The present study demonstrates that gyrB gene analysis will aid in describing novel species belonging to the genus Gordonia.

本研究利用上述两基因序列相似度初步判定4株本土Gordonia新菌种之分类地位，其中分离株CC-AB07经由生理生化特性及化学组成分析，已确认为本土Gordonia新菌种。

Phylogenetic assay indicated that this gene differed from the known germin-like proteins from gramineous family.

系统进化分析表明该基因片段与已知的来自禾本科的萌发素蛋白分属不同的进化分支，很可能是新的小麦萌发素蛋白成员。

The phylogenetic tree based on 610bp EF-1αsequence reveals that at least four lineages of F.graminearum existed on gramineous crops in China.

同时我国禾本科作物上的F.graminearum还有可能存在着更多的谱系。

The phylogenetic tree based on 610bp EF-1αsequence reveals that at least four lineages of F.graminearum existed on gramineous crops in China.

谱系2是我国首次报道的进化群，这一发现完成了谱系2在世界上从南美经尼泊尔向我国传播，进而进入韩国的这样一条传播路径。

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。

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。
