埃及伊蚊是基孔肯雅热、黄热病和登革热病毒的有效媒介,每年导致数亿人感染和5万多人死亡。Ae.的诱变作用埃及伊蚊已经与TALEN、ZFN和归巢内切酶建立,这些内切酶需要设计DNA结合蛋白结构域来提供基因组靶序列特异性。在这里,我们描述了使用CRISPR-Cas9系统来产生Ae的位点特异性突变。埃及伊蚊。该系统依赖于RNA-DNA碱基配对来产生靶向性,从而产生高效和灵活的基因组编辑试剂。我们调查了注射混合成分的效率,证明了CRISPR-Cas9通过不同的修复机制产生不同类型突变的能力,并报告了几个基因组座位上稳定的胚系突变。本工作对CRISPR-CAS9在人工智能中的使用进行了详细的探索。埃及伊蚊应适用于以前无法进行基因改造的非模式生物。
The mosquito Aedes aegypti is a potent vector of the chikungunya, yellow fever, and dengue viruses, responsible for hundreds of millions of infections and over 50,000 human deaths per year. Mutagenesis in Ae. aegypti has been established with TALENs, ZFNs, and homing endonucleases, which require the engineering of DNA-binding protein domains to provide genomic target sequence specificity. Here, we describe the use of the CRISPR-Cas9 system to generate site-specific mutations in Ae. aegypti. This system relies on RNA-DNA base-pairing to generate targeting specificity, resulting in efficient and flexible genome-editing reagents. We investigate the efficiency of injection mix compositions, demonstrate the ability of CRISPR-Cas9 to generate different types of mutations via disparate repair mechanisms, and report stable germ-line mutations in several genomic loci. This work offers a detailed exploration into the use of CRISPR-Cas9 in Ae. aegypti that should be applicable to non-model organisms previously out of reach of genetic modification.
