降低转基因植物外源基因扩散的分子策略 Molecular Strategies for Decreasing the Gene Flow of Transgenic Plants
转基因植物 基因扩散 分子策略
2008/1/8
摘要
转基因植物可以通过花粉或种子将外源基因转移到其他植物,从而对生态环境造成潜在的危害。如何降低外源基因的扩散已引起了人们的极大关注。目前降低外源基因扩散的方法主要有叶绿体转化、花粉不育、种子不育、闭花受精、无融合生殖、暂时性控制及转基因缓和等。主要对各种方法的原理和优缺点及目前的使用情况进行综述。Abstract: Transgenic plants can transfer foreign...
番茄转录调控因子基因Pti5植物表达载体的构建及其转化烟草的研究Construction of a Plant Expression Vector with Tomato Transcription Factor Gene Pti5 and Studies on Transgenic Tobaccos
Pti5-VP16基因 表达载体 转化 烟草

摘要从载体pBluescript SK+的Nde I位点处插入外源基因片段,构建了含有青鳉(Oryzias latipes)β-肌动蛋白(β-Actin)启动子和绿色荧光蛋白(GFP)标记基因的新表达载体。显微注射实验证实:在青鳉受精卵的单细胞期进行显微注射,标记基因的表达率和胚胎的存活率均较高。对嵌合体的转基因青鳉(F1)进行了两代的杂合体(F2和F3)筛选和一代的纯合体(F4)筛选,获得第4代...
转基因植物中筛选标记基因的利用及消除Using of Selective Marker Gene in Transgenic Plants and Its Removal
转基因植物 筛选标记基因 基因消除
2007/12/31
摘要在基因转移过程中,人们常常使用标记基因来筛选转化细胞或组织。常用的筛选标记基因尤其是抗生素抗性基因的使用往往对环境及植物体的生长发育产生不良影响,且影响基因多重转化。为了消除这些弊端,一种全新的发展策略即获取无选择标记的转基因植物应运而生。本文主要综述转基因植物中有关筛选标记基因及其消除方法。
