Postsynaptic mechanisms during synaptic plasticity at the Drosophila neuromuscular junction
Synaptic plasticity cells molecules cells nerve muscle
2014/12/11
The ability of established synaptic connections to strengthen and weaken (synapse plasticity) underlies higher order behavior such as learning and memory. Several gaps remain in our understanding of t...
银额果蝇(Drosophila albomicans)B染色体对繁殖的影响
B染色体 繁殖 银额果蝇
2008/2/5
摘要利用遗传背景一致的3类含有不同B染色体数目的银额果蝇(Drosophila a lbomicans)品系,对繁殖的2个参数,即净繁殖量和性比进行了比较研究。结果表明B染色体对净繁殖量有着显著的影响,其影响依赖于B染色体数目的不同而不同;低数目增加其携带者的净繁殖量,而在高含量时有使其携带者净繁殖量下降的趋势。B染色体对繁殖的影响还具有一定的时间分布特征,即3类品系净繁殖量的差异主要集中在雌蝇繁...
摘要测定了金色果蝇复合种(Drosophila auraria species complex)的5个姊妹种(D.auraria、D.biauraria、D.triauraria、D.quadraria和D.subauraria)及其近缘种D.rufa的ITS1片段和COⅡ基因的全序,以及Adh基因的部分序列。以D.rufa、D.melanogaster和D.yakuba为外群,分别用最大简约(M...
中国特有果蝇Drosophila curviceps种亚组在Drosophila immigrans种组中的种系发生地位
果蝇curviceps种亚组 果蝇immigrans种组 ITS1 Adh基因 种系发生
2008/1/26
摘要果蝇immigrans种组中的curviceps种亚组是1992年新建立的中国特有果蝇类群。该种亚组中的物种主要分布在中国大陆和台湾。目前除了形态学水平的研究外,还没有其他证据支持建立该种亚组的合理性及其起源和种系发生地位。为了在DNA分子水平上探讨果蝇curviceps种亚组在果蝇immigrans种组中的种系发生地位,从而为今后更深入地研究中国特有果蝇,甚至为果蝇亚属的进化遗传学提供理论依...
抗果蝇Dxl6蛋白抗体的制备及特异性分析Preparation and Specificity Analysis of Anti-Drosophila Dxl6 Antibody
SR蛋白 果蝇 Dxl6基因 原核表达 抗体制备
2008/1/8
摘要
为了研究果蝇中SR蛋白家族新成员Dxl6的功能，通过RT-PCR得到Dxl6的全长cDNA，并根据Dxl6基因产物的功能区，分别将Dxl6中间区域（Dxl6 middle part, Dxl6MP）、Dxl6 C末端RS结构域（Dxl6 RS domain, Dxl6RSD）序列亚克隆至pGEX-4T-1(His)6C 及pET32a 表达载体中，表达和纯化获得融合蛋白。用纯化的融合蛋白...
Testing the Randomness of the Samples of Body Size in a Replicated Design in Drosophila melanogaster Populations from the Eastern Mediterranean
Drosophila body size randomness
2010/3/26
Strong body size correlates, wing and thorax lengths, of Drosophila melanogaster populations from the Eastern Mediterranean were measured and tested for the presence of autocorrelation, i.e. nonrandom...
Implications of Locus Specific Microevolution Inferred By Genetic Distances Between Two Local Populations of Drosophila melanogaster From Turkey
Allozymes Drosophila melanogaster genetic distance alcohol dehydrogenase
2010/3/29
The standard genetic distances were calculated with 3 allozyme loci in 2 local populations of Drosophila melanogaster from Turkey. One of the distances, i.e. obtained with alcohol dehydrogenase (Adh),...
