Y. shanxianense. The reconstructed phylogenetic results indicate that Sinopotamon yangtsekiense diverge into two clades: one clade characterized by the straight terminal segment of male pleopod 1, the other one characterized by the terminal segment being curved towards dorso-innerly, i.e. tongbaiense curved slightly and shanxianense curved sharply.

重建的系统发生结果显示，长江华溪蟹分化成2个分支，一支代表雄性第1腹肢末节呈平直型的指名亚种支；另一支则代表雄性第1腹肢末节弯向背内方的内弯型支，包括稍向内弯的桐柏亚种和明显内弯的陕县亚种在内。

本课题通过从不同立地条件不同寄主采集分离到20株罗汉松属植物根瘤内生细菌进行分类地位的初步鉴定。

The molecular phylogenetic trees indicated that Oedipodinae is a monophyletic group and this subfamily is a natural one, but Catantopinae and Acridinae are non-monophyletic. Oedipodnae is a relatively primitive group within the Acrididae, whereas the Oxyinae may have diverged later than Oedipodinae, but earlier than most other species of Acridide.

分子系统树表明：斑翅蝗亚科是一单系群，该亚科是一个合法的亚科，但斑腿蝗亚科和蝗亚科都不是单系群；斑翅蝗亚科在蝗科内是一个相对原始的类群，而稻蝗亚科比斑翅蝗亚科相对进化，比蝗科的其他亚科的种类相对原始。

Results Same conservative sites and key catalytic sites existed among SjLDH and LDHs from other species. Similarity of SjLDH compared to CsLDH, TvLDH and HsLDH was 75%, 17%, 58%-60% respectively. Phylogenetic analysis demonstrated that the evolution relation between SjLDH and DmLDH was closer than the relation between SjLDH and CeLDH, the relationship between SjLDH and HsLDH-B,-C was closer than HsLDH-A. Three trans-membrane regions were found, the region of 98aa-106aa in three hydrophilia regions located outside of membrane was inferred as the major antigen epitope. This antigen epitope had significant difference with LDHs from protozoon （ Pf ., Tg ., Tv .） and had 1-3 amino acid residue difference with MmLDH, HsLDH-A,-B,-C, and was the same with CsLDH. One of the key catalytic residues and substrate binding loop were located in this region. Tertiary structure demonstrated that 98aa-106aa was on the surface of the protein and formed a substrate binding loop, other two key catalytic sites were at the position near the loop.

结果 SjLDH与其他物种的同源序列含相同的保守位点及催化活性位点，与华支睾吸虫LDH同源性最高为75％，与阴道毛滴虫LDH同源性最低为17%，与人LDH（HsLDH-A，-B，-C）的同源性为58%~60％； SjLDH与果蝇的进化距离较秀丽隐杆线虫为近，3种人LDH中与HsLDH-B、-C的进化距离较HsLDH-A为近；该蛋白具有3个跨膜区域，3个高亲水性区域，主要的线性表位98aa~106aa位于膜外，与原虫LDH相同区域差异显著，而与其他LDH有1~3个氨基酸的差异，关键催化位点之一及底物丙酮酸结合区域位于该区域，蛋白质同源模建分析表明该区域位于蛋白表面形成环状结构，3个关键催化位点位于该区域或在其附近。

Although Pulsatilla can easily be distinguished from Anemone by the former having a long, plumose beak on the achenes formed by the persistent style, phylogenetic studies have shown that they are probably congeneric.

尽管Pulsatilla 能容易地通过其在瘦果上有宿存花柱形成的长的、羽状喙，与银莲花属区分，系统发育的研究显示它们可能是同属。

Molecular phylogenetic tree constructed by NJ method suggests that African wild dog is the earliest divergent. Wolf, dog, and simien fox which belong to genus Canis are combined into one branch which diverged earlier than raccoon dog, red fox and blue fox. Red fox is more related to blue fox than the other animals.

NJ法构建的分子系统树显示，非洲野犬最先从犬科动物中分化出来；犬属的狼、狗和西门豺等3种为系统树上独立的一支，且其分歧的时间较赤狐、蓝狐和貉早；赤狐和蓝狐具有较近的亲缘关系。
