Most importantly, our team are famous for much research on ecology, physiology,molecular phylogenesis of bats at home and abroad, we have gained much originative result in this field, and we firstly found and studied the third piscivorous bat, Myotis ricketti.We provide evidence that the species Myotis ricketti is piscivorous, and close negative relationships were found firstly within Rhinolophidae and Hipposideridae between call frequency and ear length. Some species of taxology status in rhinolophidae were studied by molecular phylogenesis; phylogenesis relationship between rhinolophidae and hipposideridae and different populations of miniopterus schreibersii were also studied; we also studied Social structure of Tylonycteris pachypusa and T. robustula and the isolating mechanisms of ecological niches.

Since polar organic crystals have noncentric structures, the existence of polar axis in the crystals has a significant effect on the molecular arrangement and on the crystal growth.
极性有机晶体在不同的溶剂中具有明显不同的生长习性,主要有两个方面的原因:一是极性有机晶体属非中心对称性晶类,晶体具有极轴,极轴的存在对分子堆积和晶体生长具有重要影响;另一是极性有机晶体的界面结构不同,溶剂与晶体界面的相互作用不同,使得晶体同一面族的生长速率不同,从而导致了晶体习性的改变。

This whole research constitutes two independent projects, that is "Estimating divergence times among subfamilies in Nymphalidae" and "Fine- and landscape-scale spatial genetic structure of cushion rockjasmine, Androsace tapete, across southern Qinghai-Tibetan Plateau", which discussed respectively the application of molecular evolutionary analysis in two aspects of evolutionary biology.
分子进化分析就是利用分子数据来研究进化问题。地球上呈现的生物多样性则是突变和自然选择的产物,是生物进化的结果。生物进化的过程包含有两个面:基因的长期进化和遗传多样性,也就是通常意义上的大进化和小进化。该项目就是以两个不同的实验——即&蛱蝶科各亚科间分歧时间的估计&和&青藏高原垫状点地梅的空间遗传结构分析&——分别探讨了分子进化分析在大小进化两个方面的应用。

Our results suggested that the channel contains two of each subunit and the stoichiometry is apt to 2:2 if hetermeric ASIC channel is a tetramer,while the assembly of ASICs is random,the stoichiometry is not fixed(2:1 and 1:2 coexist)if hetermeric ASIC channel is a trimer.This study provided interesting new data supporting the occurrence of the homomeric and heteromeric assembly of ASICs.
另外,我们还对ASIC异聚体的分子比情况进行了初步的探讨,结果发现如果所形成的ASICs异聚体通道是四聚体,那么每种亚单位有两个,分子比倾向于2∶2;如果是三聚体,则提示ASICs的装配是随意的,分子比是不固定的,2∶1和1∶2这两种情况都存在。

NodD binds to and bends target promoters through anchoring two tandem and individual specific DNA sites. NodD functions as a tetramer, which has a V-shaped main body. Tetrameric NodD is to change its own conformation rather than its oligomeric forms in response to small signal molecules. The specific interaction between each NodD DNA-binding domain and each specific DNA site does not alter itself in spite of naringenin induction, and the induced conformational change is transferred from protein to DNA. Only the DNA conformation incited by induced NodD is competent for RNA polymerase to form the transcriptional open complex. It cannot be excluded that NodD may have protein-to-protein contacts with RNA polymerase, and that the NodD conformational change may also directly contribute to the transcriptional open complex formation. However, the NodD conformational change itself cannot serve as the determinant of the transcriptional molecular switch.
通过研究,我们提出了初步的NodD操纵子激活模型:第一,四聚体是NodD蛋白的功能单位,它通过铆钉两个串联的相对独立的DNA靶位点结合被诱导的启动子;第二,小分子配基的结合是改变NodD四聚体的构象而不是引发不同形式的寡聚体,在我们的模型中,NodD四聚体缩小其V形主体的弯折角,进而缩短其DNA结合功能域的间距;第三,小分子信号的诱导并没有改变NodD的DNA结合域和其DNA靶位点的相互作用,NodD的构象改变由蛋白质经其双铆钉位点传递给DNA;第四,只有诱导状态的NodD激发的DNA构象才能有效地使RNA聚合酶形成转录开放复合物;第五,不排除NodD与RNA聚合酶可能有直接的相互接触位点,不排除NodD构象的改变可能直接有利于RNA聚合酶形成转录开放复合物,但是我们认为NodD构象改变本身不是充当转录激活开关的决定因素。
