Preious studies hae shown that a reduction in insulin - like signaling in the neurons extends the lifespan in the worm , caenorhabditis elegans , and the fruit fly , drosophila melanogaster 之前已经有研究证实，减少神经元中胰岛素样信号可以延长蠕虫、新杆状线虫、果蝇及黑腹果蝇的寿命。
Flybase is a database of genetic and molecular data for drosophila . flybase includes data on all species from the family drosophilidae ; the primary species represented is drosophila melanogaster 果蝇库为果蝇遗传和分子数据库，包括果蝇科的各个种类，其中表述的主要类型是黑腹果蝇。
Flybase is a database of genetic and molecular data for drosophila . flybase includes data on all species from the family drosophilidae ; the primary species represented is drosophila melanogaster 果蝇数据库：为果蝇遗传分子研究数据库。包含果蝇科所有种类的资料，其中以黄果蝇为主。
Unlike other methods , which lack penetrating power and can damage the specimen , mpm delivers crisp , clear images , even in thicker tissue samples like drosophila salivary glands 其它方法缺乏穿透力，并且会损害标本， mpm不同，它可以呈现出锐利清晰的图像，即使像果蝇唾液腺组织这样较薄的标本也是这样。
Based on the foundation research of the interaction of virus and host actin , we recombine gfp gene - a reporter gene - with 5c actin gene of drosophila melanogaster , a gfp - actin fusion gene was obtained 本文在总结前人关于病毒与宿主肌动蛋白相互作用的研究的基础上，利用绿色荧光蛋白基因为标记基因，与果蝇肌动蛋白基因5cactin基因融合，构成gfp - actin融合基因。
The nucleotide sequence similarity and the putative amino acid sequence similarity of alpha - amylase gene of bombyx mandarina to those of bombyx mori , spodotera fruiperda , ostrinia nubilalis on 25 and drosophila subobscwa are 90 % , 12 % , 12 % , 5 % and 98 % , 80 % , 78 % , 58 % respectively ）相似性分别为90o 、 12 、 12o 、 50 ，推定氨基酸序列相似性分别为98 、 80 、 78 、 58 ，表明：野桑蚕与家蚕的亲缘关系最近，果蝇与野桑蚕的亲缘关系相对较远。
Found the phenomenon observed in the nematode caenorhabditis elegans for the first time in 1998 , consequently similar processes have been described for drosophila melanogaster , trypanosome , mammals including humans . the mechanism is that sirnas is the mediator , which can induce the risc to the target mrna and degrade it . recently there was great progress in the specific gene therapy and anti - virus , and rnai has been a focus of rna molecular therapy 自1998年fire等在研究线虫时首次发现以来，相继在果蝇、涡虫、锥虫、小鼠及哺乳动物细胞中发现rnai现象。一般认为： rnai第四军医大学硕士学位论文效应作用机制是sirnaskmallinterferinguaduplex ）作为中介分于，引导risc （ rnaiinducingsuppresscomplex ）至靶基因m洲a处，随后核酸内切酶将之降解。
Two specific primers were designed and synthesized based on the conservative sequence contrasted to drosophila and other species mt gene by computer retrieving , which were named primerl and primer2 , the sequence of primer1 was : 5 " caa gtg aat cat ctc agt gc3 " , and that of primer2was : 5 " tgt aga gag aca aga tgc ag 3 " . rt - pcr technique was adoped to synthesizing the first - band of cdna , the second - band of cdna and expanding dna directly only by one step 根据已发表的果蝇以及其它生物的mt基因的保守序列，通过计算机同源检索比较，设计两个扩增引物，命名为引物1和引物2 ，引物1的序列是： 5 ’ caagtgaatcatctcagtgc3 ’ ，引物2的序列是： 5 ’ tgtagagagacaagatgcag3 ’ 。
In this thesis , we studied the effects of acetylation on hsp gene transcription regulation in drosophila melanogaster , in an attempt to disclose the mechanisms of the acetylation in hsp gene inducible transcription , at both the molecular and the chromosomal levels . the main results and conclusions are as followings 本文以黑腹果蝇为实验材料，从不同角度研究了乙酰化修饰与热休克基因表达调控的关系，并对乙酰化修饰在热休克基因的诱导表达中的作用机制进行了探讨，建立了分子水平与染色体水平上的联系。
Two positive clones were sequenced , and the results showed that its nuclcotidc sequence includes an open reading segment which codes for a 45 - amino acids protein and three endonuclcase sites which arc1 bgii , bamh i and bgi ii , this protein was identified as metallothionein based on its characteristic described above and its similarity ( 85 % ) to the mtn gene of drosophila : the 10 cysteine residues present occur in five pairs of cys - x - cys , x is serine , valine , ilistidine or lysine 结果显示：扩增的cdna片段长度为289bp ，其中含有一个编码45个氨基酸的开放阅读框，阅读框所编码的氨基酸中含有10个半胱氨酸，且在序列中均排列成cys - x - cys ，其中x为ser 、 val 、 his或lys 。这些特征说明扩增的基因片段为家蝇mt基因序列的一部分。此基因序列片段与果蝇mtn基因序列的同源性达到85 . 0 ，扩增的基因序列中含有三个内切酶位点bg 、 bam和bg ，这一点也和果蝇mtn基因十分相似。
