查询词典 phylogenetic development

Descriptions of single new species may be accepted if accompanied by significant information on zoogeography, ecology, phylogenetic relationships, or other biological concerns.

如含有在动物地理、生态学、系统发生关系或在生物学其它方面具有显著意义的信息，可接受有关单个新种的简短描述。

该基因片段具有其它植物GA20氧化酶基因中存在的保守区；同时，与多种单子叶植物的GA20氧化酶基因的核苷酸和氨基酸序列的同源性在80％和75％以上。

Seven major bacterial isolates were obtained and purified. Their 16S rRNA genes were amplified by PCR for sequencing and their identities were determined with homology comparisons. Five of the seven isolates belong to Actinomycetales including Kocuria KD139, Rhodococcus KD140, Rhodococcus KD142, Arthrobacter KD230, and Arthrobacter KD232; one is classified as Bacillus d KD178; and another one as Stenotrophomonas KD237. The phylogenetic tree was also constructed based on the analysis of 16S rRNA gene sequences.

通过对分离菌株的16S rRNA基因序列进行分析，发现其中5株细菌分别属于放线菌目的考克氏菌属(KD139)、红球菌属(KD140和KD142)和节杆菌属(KD230和KD232)， 1株细菌属于杆菌目的芽胞杆菌d属(KD178)，另外1株细菌属于黄色单孢菌目的寡食单胞菌属(KD237)；同时我们构建了系统进化树，确定分离菌株的相对进化地位。

Sequence comparison shows that MuMADS2 belongs to the AGAMOUS subfamily. Furthermore, phylogenetic analysis suggests that MuMADS2 is most likely a class DMADS-box gene.

将MuMADS2与其它植物来源的MADS-box基因进行序列比较发现，MuMADS2属于MADS-box基因的AGAMOUS亚族的D世系。

The phylogenetic analysis based on the sequences in this region indicated that the y-type HMW glutenin subunits of Agropyron elongatum species were different from other subunits, whereas the x-type subunits of them were most closely related to that from the B genome.

推测四倍体长穗偃麦草中的E1基因组可能起源于二倍体的E基因组。与来自小麦族的A、B、D和G基因组部分亚基基因的启动子序列比较表明，小麦族的这一区域在进化上是相当保守的，不同基因组来源的序列同源性都在90%以上。

This paper reviewed the application of nuclear ribosomal DNA internal transcribed spacer region sequences in phylogenetic study of angiosperms at intra\|inter genera or family levels in recent years at home and abroad. Combined with the research of Chinese \%Alpinia \%Roxb.

本文就近年来国内外有关被子植物核糖体DNA中的内转录间隔区序列在植物属内、近缘属间乃至科内系统发育研究中的应用，结合作者在中国姜科山姜属 AlpiniaRoxb 。

The vertebrate TSHβ protein sequences had been used to construct Neighbor-joining and Maximum parsimony phylogenetic tree. As analyzed, Andrias davidianus derived from amphibia firstly, which could reflect its original evolutionary status.

采用邻接法和最大简约法对部分脊椎动物TSHβ氨基酸序列构建分子系统树，结果显示有尾目大鲵为两栖动物中较早分化的一支，表明其进化地位较原始。

In addition, the reconstructed phylogenetic tree based on cDNA and DNA sequences encoding C-terminal non-repetitive region of MaSp1 (Major ampullate spidroin-1) also showed that Deinopoidea and Araneoidea are not sister groups.

另外，依据编码大壶状腺丝蛋白-1(MaSp1)C末端非重复氨基酸序列区段的核酸序列重建的系统发生树也证实圆网蛛类并非单系发生。

The comparison of sequences showed that the determined sequence was most similar to those in GenBank (AF016546)(similarity level, 97.9%), Phylogenetic analysis indicated that the resulting sequence was more similar to those of Mycoplasma spp.(homo!ogy level, about 70%), but was farther from Anaplasma spp.( homology level, about 50%).

系统发育分析表明，所测序列与支原体属病原代表种的序列接近，同源性约为70%，而与无浆体科病原代表种的序列相差较远，同源性约为50%。

There was high level of confidence on anopheline phylogenetic relationship reconstructed by combining nuclear genes with mitochondrial genes.

该文还介绍了建立在基因组计划基础上的全新学科——系统发育基因组学。

阿基坦法国西南部一个历史地区，位于比利牛斯山和加隆河之间，在1137年阿基坦的埃莉诺与国王路易斯七世结婚之后阿基坦公国加入法国，但当她再嫁英国亨利二世后，其归属权便受到争议

There are moments when I look at the smiling , happy faces of my expectant staff and wonder how they will cope when confronted by an outraged housemaster along with an unrepentant and recalcitrant bleached blond teenager in 18 years ' time .

有时候，我看着那些满怀期待的员工微笑，幸福的脸，想着当他们遇到一位愤怒的宿舍管理员和一位不知悔改，叛逆，而且将头发染成白色的18岁少年时，他们会如何处理。
