Homology modeling of 3-D structure of two AChE from L.entomophila were constructed using H.sapiens(1p0i:A) native BuChE structure and Drosophila melanogaster(1d×4:A) native AChE structure as templates,respectively,by SWISS-MODEL.The catalytic triad were found and denoted in the 3-D structure of AChE from L. entomophila referring to T.californica.2.2 Gene cloning ofβ-actin and mRNA expression levels of two AChE genes from L. entomophilaBecause no reference gene has ever been used in Real Time PCR for L.entomophila in GeneBank,a fragment ofβ-actin gene was cloned from L.entomophila(GenBank Accession No.: FJ041117).It consists of 822 bp encoding a protein of 273 amino acids residues.

利用蛋白质结构同源建模工具，分别以人丁酰胆碱酯酶(1p0i：A)和果蝇乙酰胆碱酯酶(1d×4：A)的蛋白晶体结构为模板，对嗜虫书虱2个AChE的三维结构进行同源建模，并在三维结构中发现了AChE的酶解活性位点，证明嗜虫书虱体内也存在2个AChE基因。2.2嗜虫书虱β-actin基因克隆及乙酰胆碱酯酶基因mRNA表达水平研究目前关于嗜虫书虱的分子生物学研究较少，在GenBank中没有可用作内参基因的序列，因此本研究从嗜虫书虱体内克隆获得β—actin基因片段(GenBank登录号：FJ041117)，该片段长度为822 bp，编码273个氨基酸残基，同源性比对分析表明该片段与其它昆虫的β—actin基因具有很高的同源性。

The term"homeodomain"has evolved to define a class of protein domains that has recognizable similarity to a 60 amino acid motif (encoded by 180 bp homeobox sequences) originally recognized in three Drosophila homeotic and segmentation proteins. The homeodomains that have been tested contain sequence-specific DNA binding activities and are part of larger proteins that function as transcriptional regulators.

其中一类转录因子通过同源域结合特定的DNA序列，这种特殊的转录因子都包含一个同源盒，它有180bp序列可以编码DNA结合同源域，称同源盒基因（Homeobox gene，Hox gene），带有同源框的基因经过转录产生带有同源域的蛋白质。

Until now, the genes related to apoptosis of Bombyx mori which have logged in NCBI includes the BmP109, BmIap, BmCdc2, BmIce, BmIce2, BmIcad and 6G1 gene. Thereinto, the apoptotic function of the homologic genes of BmIce in Homo sapiens, drosophila and C.elegans have been identified. The aim of this study was to identify the function of the interleukin-1 beta converting enzyme of Bombyx mori, BmIce.

目前已在NCBI上登录克隆序列的家蚕细胞凋亡相关基因有：含Bcl-2家族同源域BH结构域的BmP109，凋亡抑制因子BmIap，生存因子途径中的BmCdc2，家蚕白介素转换酶BmIce和BmIce2，caspase活化的DNA酶抑制剂BmIead基因和30k蛋白中的6G1基因。

Using synchro drosophila as material, pouring purslane liquid or hydroxyketone of different density into substrate,after culturing,anti-decrepit effect can be observed.

用同步果蝇为材料，在培养基中添加不同浓度的马齿苋水提液或醇水提液，观察到了马齿苋的抗衰老效应，并且可以影响果蝇幼虫期的长短及果蝇的繁殖力。

When the frequency of codon usage of citrus was compared to Homo sapiens, Drosophila melanogaster, Saccharomyces cerevisiac and Escherichia coli, we found that the codon preference is considerably different between citrus and non-plant species. While compared to Arabidopsis thaliana, Lycopersicon esculentum, Oryza sativa and Musa acuminata, we found that the codon preference was identical in dicotyledons, but was different between citrus and monocotyledon, Oryza sativa and Musa acuminate.

将柑橘的密码子使用频率与人、果蝇、酵母和大肠杆菌等不同种类模式生物比较后发现，柑橘密码子的偏爱性与不同种类生物有不同程度的差异；但将柑橘的密码子使用频率与拟南芥、番茄、水稻和尖叶蕉等不同种类的植物相比，发现柑橘密码子的偏爱性与同为双子叶植物的拟南芥、番茄完全一样，而与水稻、尖叶蕉这2种单子叶植物均有较大的差异。
