摘要: 采用CRISPR/Cas9基因编辑技术,分别对烟草(Nicotiana tabacum L.)品种遵烟6号和K326的多酚氧化酶(PPO)家族基因成员LOC107810501进行靶向敲除。结果表明,LOC107810501基因被敲除后,在烟草的阳性编辑单株中未检测到该基因的表达,同时LOC107821546、LOC107786520、LOC107773093、LOC107787563、LOC107805360基因的相对表达量均明显下降。研究获得了低PPO活性的烟草T0突变单株,T1世代测序检测证明突变性状可以稳定遗传。

Abstract: Using CRISPR/Cas9 gene editing technology, the polyphenol oxidase (PPO) family gene member LOC107810501 of tobacco(Nicotiana tabacum L.) varieties Zunyan 6 and K326 was targeted and knocked out. The results showed that after knocking out the LOC107810501 gene, no expression of this gene was detected in the positive edited plants of tobacco. At the same time, the relative expression levels of LOC107821546, LOC107786520,LOC107773093, LOC107787563, and LOC107805360 genes were significantly reduced. The study obtained T0 mutant plants of tobacco with low PPO activity, and T1 generation sequencing confirmed that the mutant trait could be stably inherited.
