查询词典 phylogenetical

Based on the morphological and physio-biochemical characteristics, combining with the phylogenetical analyses of 16S rDNA sequence, the EMs were identified as follows: stains CB〓 and FB〓 as Cellulomonas sp.

Sequence analysis and phylogenetical study showed that this cDNA contained 778 nucleotides, with a 627 bp open reading frame flanked with a 44 bp 5' UTR and a 107 bp 3' UTR. The encoded 208 amino acids housefly Attacin shared a high similarity of 50%~70% with that of the other dipterous insects. In addition, the phylogenetical analysis also indicated that the Attacin from housefly was in the same branch with those of other species, suggesting that they come from the same ancestor.

家蝇Attacin的cDNA全长778 bp，其中包括627 bp的开放式读码框，44 bp的5ˊ末端非编码区(5ˊUTR)和107 bp的3ˊ末端非编码区(3ˊUTR)，相应的蛋白产物含208个氨基酸；与其他双翅目昆虫的Attacin具有很高的相似性，约50%～70%；以邻接法(Neighbor-Joining，NJ)所构建的系统关系表明家蝇的Attacin与其他双翅目昆虫的Attacin起源于共同的祖先。

With the phylogenetical methods, we compared the ancient Turfan with modern Xinjiang and four Central Asian populations in order to detect their relationship.

我们对新疆地区的古代人群的遗传距离、核酸多样性和平均配对差异与东亚、欧洲和中亚的现代群体进行了比较。

The ITS sequences contain many variable sites and phylogenetical informative sites among related species of genus Vigna and phylogenetic relationships among species could be established succesfully.

美洲来源的聚为一类，它们的遗传距离较远，大多在20％左右，遗传多样性较高，位于系统树的最基部，可能为较原始起源的种。

Pteridophytes have a longer evolutionary history and have endured greater losses of phylogenetical information than spermatophytes. Therefore, reconstructing the evolutionary history of pteridophytes has been a challenge to systematists.

蕨类植物是一群非常古老的植物，在其漫长的演化历史中丢失了大量的系统发生信息，因此重建其系统演化关系是蕨类植物学家所面临的重要任务之一。

Molecular identification was done for YL001 and YL002 strain, the complete 16S rRNA sequence was amplified and cloned; Sequence and phylogenetical analysis were studied with parameters determination.

对YL001和YL002菌株进行分子鉴定，PCR扩增并克隆其16SrRNA全序列，对其全序列进行了序列测定及系统进化分析，并采用参数测定法对其培养特性进行了初步研究。

Bacterial diversity of sediment in shrimp pond was analyzed by using PCR-DGGE technique, the Shannon-wiener index is 3.4971, the Richness is 41 and the Evenness is 0.94171; 17 dominant bands were excised from DGGE profile of surface sediment bacteria in shrimp pond and the V3 region of 16S rRNA gene was cloned and sequenced followed by phylogenetical analysis.

对虾池表层沉积物细菌多样性进行分析，得出该沉积环境细菌多样性指数为3.4971，丰度为41，均匀度指数为0.94171；对DGGE图谱上的特征条带进行切割回收和克隆测序后得到了优势菌的信息。

Phylogenetic analysis showed that the proteobacteria were the dominant group both in the sediments and waters,γ-proteobacteria and δ-proteobacteria were dominant in the sediments,α-proteobacteria were dominant in the water. However, all subphyla of proteobacteria presented phylogenetical divergence at the two sites.

各站位中主要为变形菌门，沉积物中γ-Proteobacteria和δ-Proteobacteria亚门占优势，水中则以α-Proteobacteria亚门占优势，但各亚门微生物在两个站位中存在明显系统发育学分歧。
