1、中国海洋大学硕士学位论文皱纹盘鲍(Haliotisdiscushannai)外套膜耐维生素E缺乏消减cDNA文库的构建及相关基因的克隆姓名:刘晶申请学位级别:硕士专业:水生生物学指导教师:麦康森20070601皱纹盘鲍(Haliotisdiscushannai)外套膜耐维生素E缺乏消减cDNA文库的构建及相关基因的克隆中文摘要本文利用抑制消减杂交技术(suppressionsubtractivehybridization,SSH)来构建消减文库的方法,克隆维生素E缺乏时皱纹盘鲍(Haliotisdiscushannai)外套膜差异性表达的基因。我们选取了片段大小不同的48
2、个克隆测序,其中有16个新基因,10个谷胱甘肽转移酶的基因,5个谷胱甘肽过氧化物酶基因,2个过氧化氢酶基因,3个羟基类固醇脱氢酶基因,4个酪氨酸激酶基因,1个类甲状腺过氧化物酶蛋白基因,3个纤维素酶基因,1个cAMP效应元件结合蛋白基因,3个贝壳生物矿化相关蛋白的基因。并在此基础上,对外套膜消减文库中所得到的与过氧化酶相关的两个基因,类纤维素基因、类钙结合蛋白基因以及两个贝壳蛋白基因的片段,利用RACE技术获得了与过氧化酶相关的两个基因和类钙结合蛋白基因的全长,并获得了类纤维素基因的5’产物和两个贝壳蛋白基因的3’产物,为迸一步研究这些基因在不同维生素水平和不同组织中的表
