According to BLAST results in GenBank, molecular phylogenetic tree (Paup 4.0), and the morphological, physiological and biochemical characters, the strain was preliminarily identified as a Streptomyces.

在GenBank中进行BLAST 相似性分析，利用Paup 4.0 构建系统发育树，并结合形态特征、培养特征及生理生化特征，确定此菌可以划分为链霉菌属，且与嗜热淀粉酶链霉菌S。

Siltp expresses in stem, leaves and grains. Using software PAUP to analyze evolution of LTP from 17 different plants, phylogenetic tree allows the conclusion that LTP has four groups. Differentiation happened earlier in wheat,while in the other monocots such as maize, millet,barley and rice happened later.

利用软件PAUP对17种植物的LTP进行进化分析，从进化系统树可以看出LTP有4个分支，其中，小麦发生分化较早，其它几种单子叶植物如玉米、谷子、大麦和水稻分化较晚，说明发生了早期的基因复制事件。

On the base of the constructing phylogenetic tree using PAUP 4.0, MP and NJ (neighbor-joining) trees of diverse pectate and pectin lyases showed that pectate lyases from plant, pectin lyases from fungi and pectate lyases from bateria belong to different groups, respectively. The pectate lyase A of Aspergillus nidulans is more closely related to plant pectate lyases than to pectin lyase from fungi and pectate lyases from bacteria. The pectin lyase from Pseudomonas syringae is more closely related to fungi pectin lyases than other lyases.

构建的MP树和NJ树(neighbor-joining)显示：来自植物的果胶酸裂解酶、真菌的果胶酸酯裂解酶、细菌的果胶酸裂解酶分别可聚为一个独立的类群；相对于细菌果胶酸裂解酶和真菌果胶酸酯裂解酶而言，构巢曲霉的果胶酸裂解酶A和植物的果胶酸裂解酶之间有较近的亲缘关系；细菌Pseudomonas syringae的果胶酸酯裂解酶和真菌的果胶酸酯裂解酶之间的亲缘关系较近。

The evolutionary relationships were investgated by comparing the results from molecular data alone or molecular data combined morphological characters using different analysis methods: maximum parsimony by PAUP(superscript *) 4.0 and Bayesian inference by MrBayes 3.0B4. Base composition and ti/tv of 28S rDNA D2 regions were analyzed by PAUP(superscript *) 4.0. The results showed that GC content of the 28S rDNA D2 gene sequences of subfamily Euphorinae ranges from 40.00% to 49.25%. Transversion frequency of sequence variable sites among species of Euphorinae was higher than that of transition. The subfamily Euphorinae was proved to be a paraphyletic group with close relationship to subfamilies Neoneurinae and Cenocoelinae; only two tribes, Meterorini and Microctonini, were proved to be monophyletic groups; Centistini, Cosmophorini, Euphorini and Dinocampini were paraphyletic groups; the basal position of tribe Meterorini within Euphorinae was partially supported by our phylogenetic trees, and tribe Microctonini was proved to be a group at the top of the trees.

结果表明：优茧蜂亚科的28S rDNA D2基因序列片段的GC%含量在40.00%~49.25%之间变动，而对于碱基替代情况来讲，优茧蜂亚科各个成员间序列变异位点上颠换大于转换；不同的分析和算法所产生的系统发育树都表明目前根据形态定义出的优茧蜂亚科Euphorinae不是一个单系群，而是一个与蚁茧蜂亚科Neoneurinae和高腹茧蜂亚科Cenocoelinae混杂在一起的并系群；在优茧蜂亚科内部，悬茧蜂族Meterorini和食甲茧蜂族Microctonini（排除猎户茧蜂属Orionis）为单系群，而宽鞘茧蜂族Centistini、大颚茧蜂族Cosmophorini、优茧蜂族Euphorini、瓢虫茧蜂族Dinocampini为并系群；悬茧蜂族Meterorini在优茧蜂亚科Euphorinae内位于基部位置的观点得到部分的支持，同时食甲茧蜂族Microctonini被判定为相对进化的类群。

Interestingly, the phylogenetic analysis of HSP70 revealed that planarian had a closer relationship to vertebrates, but far from to other invertebrates such as D. melanogaster and C. elegans.

有趣的是， HSP70亲缘关系分析表明：涡虫更靠近脊椎动物，而与无脊椎动物果蝇和线虫相距较远。

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.
