摘要:

新兴的基因编辑技术CRISPR/Cas9推动功能基因组学研究和作物遗传改良进程然而,在转化及后续突变鉴定过程,转基因植株的筛选工作通常效率较低且费时费力本研究开发了一种高效的可视化标记系统——可视化大豆编辑系统(VSES:Visual Soybean Editing System)。该系统通过Cas9表达载体与一个由组成型启动子驱动的DsRed2标记表达盒相整合,从而能够直观地筛选转基因大豆植株。VSES系统具有三个显著优势:1)增强DsRed2表达使携带Cas9的种子在自然光下即可通过种皮颜色实现裸眼可视2在苗期即可通过茎叶颜色快速区分转基因植株;3)将荧光标记表达盒与基因编辑载体整合,经测序验证不影响CRISPR/Cas9系统的基因编辑效率。该系统解决了传统筛选方法效率低和耗时长的技术瓶颈,为大豆基因编辑研究提供了便捷的技术支撑。
