摘要
表达载体的构建在植物基因工程研究中占据重要地位,直接关系到目的基因的表达效果。作者在收集整理前人的工作基础上,比较分析了5种不同载体构建方法的特点,给出了不同载体构建方法的适用性建议,期望能对植物基因工程中的载体构建工作提供有益帮助。在构建多片段连接的小载体的时候推荐用一步克隆法,在构建多片段连接的复杂的大载体时采用相应的复杂载体构建技术,在已获得无选择标记的转基因植株时采用三段T-DNA构建方法构建载体。在做基因功能验证时采用的Gateway技术,非常简单的载体构建可以采用传统的酶切连接的构建方式。现在的主流构建载体方式是利用结合其他手段的Gateway技术,未来载体的发展趋势将是无酶连接。
