最近,CRISPR - Cas(聚集的,有规则间隔的短回文重复序列- CRISPR -相关蛋白)系统已被用于生产抗DNA病毒感染的植物。然而,目前还没有利用CRISPR‐Cas系统直接靶向病毒基因组的植物RNA病毒控制方法。在这里,我们重新编程了来自新弗朗西斯菌的CRISPR - Cas9系统,以赋予本烟和拟南芥植物对RNA病毒的分子免疫。表达黄瓜花叶病毒(CMV)或烟草花叶病毒(TMV)特异性FnCas9和sgRNA的植株表现出明显的病毒感染症状减轻和病毒RNA积累减少。此外,在转基因病毒靶向植物中,这种抗性是可遗传的,后代的病毒积累明显减少。这些数据表明,CRISPR/Cas9系统可用于培育对RNA病毒具有稳定抗性的植物,从而扩大了该技术在农业领域的病毒控制应用。
Recently, CRISPR‐Cas (clustered, regularly interspaced short palindromic repeats–CRISPR‐associated proteins) system has been used to produce plants resistant to DNA virus infections. However, there is no RNA virus control method in plants that uses CRISPR‐Cas system to target the viral genome directly. Here, we reprogrammed the CRISPR‐Cas9 system from Francisella novicida to confer molecular immunity against RNA viruses in Nicotiana benthamiana and Arabidopsis plants. Plants expressing FnCas9 and sgRNA specific for the cucumber mosaic virus (CMV) or tobacco mosaic virus (TMV) exhibited significantly attenuated virus infection symptoms and reduced viral RNA accumulation. Furthermore, in the transgenic virus‐targeting plants, the resistance was inheritable and the progenies showed significantly less virus accumulation. These data reveal that the CRISPR/Cas9 system can be used to produce plant that stable resistant to RNA viruses, thereby broadening the use of such technology for virus control in agricultural field.
