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.

系统鉴定分析表明，筛选的CB〓和FB〓菌株属于纤维单胞菌属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。
