中国波翅青尺蛾属分类研究(鳞翅目:尺蛾科:尺蛾亚科)

波翅青尺蛾属Thalera世界共记录6种和5亚种。中国已知3种和3亚种,本文记述5种和3亚种,其中包括采自四川巴塘1新种淡波翅青尺蛾Thalera simpliria sp.nov.和1新纪录种。文中给出了中国波翅青尺蛾属分种检索表和新种的成虫及外生殖器图。淡波翅青尺蛾,新种Thalera simpliria sp.nov.(图2,3,6,7）新种与Th.lacerataria Graeser,1889相似,但有以下不同：新种前翅外缘在M1与M3之间的缺刻极浅;前后翅外线较圆滑：♂外生殖器抱器瓣基部的三角形骨化片细尖,囊形突较细,钩形突较短粗;♀外生殖器后阴片有一方形弱骨化区域。     

甘肃中部汝尺蛾属和幅尺蛾属新种记述(鳞翅目:尺蛾科, 花尺蛾亚科)

甘肃中部的连城林区地处祁连山东麓,青藏高原东北角,山高林密,尺蛾种类十分丰富。近年在尺蛾区系调查中,已采集并鉴定近200种,其中大部分为青藏区种类或古北界广布种。下述甘肃中部汝尺蛾属Rheumaptera Hǖbner和幅尺峨属Photoscotosia Warreen 4新种模式标本保存在中国科学院动物研究所。

中国尺蛾科新记录属——泽尺蛾属及其一新记录种记述（鳞翅目：尺蛾科：灰尺蛾亚科）

系统修订了中国绮夜蛾属的种类,将中国记录的11种订正为10种。其中,原记录的白缘绮夜蛾A.nivipicta经鉴定为大理石绮夜蛾A.marmoralis的误订名,迭绮夜蛾A.disrupta被鉴定为斑绮夜蛾A.sexpunctata的同物异名。检视标本均存放于中国科学院动物研究所标本馆。     

Quadruplexes of human telomere DNA analogs designed to contain G:A:G:A,G:G:A:A,and A:A:A:A tetrads

Replacement of two to four guanines by adenines in the human telomere DNA repeat dG₃(TTAG₃)₃ did not hinder the formation of quadruplexes if the substitutions took place in the terminal tetrad bridged by the diagonal loop of the intramolecular antiparallel three‐tetrad scaffold, as proved by CD and PAGE in both Na⁺ and K⁺ solutions. Thermodynamic data showed that, in Na⁺ solution, the dG₃(TTAG₃)₃ quadruplex was destabilized, the least by the two G:A:G:A tetrads, the most by the G:G:A:A tetrad in which the adenosines replaced syn‐guanosines. In physiological K⁺ solution, the highest destabilization was caused by the 4A tetrad. In K⁺, only the unmodified dG₃(TTAG₃)₃ quadruplex rearranged into a K⁺‐dependent quadruplex form, none of the multiple adenine‐modified structures did so. This may imply biological consequences for nonrepaired A‐for‐G mutations. © 2010 Wiley Periodicals, Inc. Biopolymers 93: 880–886, 2010.
