草地贪夜蛾SoxC基因敲除后的表型
利用CRISPR/Cas9技术对草地贪夜蛾SoxC基因进行敲除。
步骤(1):根据CRISPR/Cas9技术体系的基本原则,设计草地贪夜蛾SoxC基因的敲除靶位点,包括两个敲除靶位点,以SoxC基因为模板设计合成敲除靶位点sgRNA的引物序列为(SEQ ID NO.3-5):SFsg-F1:5’-TAATACGACTCACTATAGGGGCCTGTACTTGTAGTCGGTTTTAGAGCTAGAAATAGCAAGTTAAAATAA-3’(第一个靶位点上游引物),SFsg-F2:5’-TAATACGACTCACTATAGGCAACACCCCTGTTGTTATGTTTTAGAGCTAGAAATAGCAAGTTAAAATAA-3(第二个靶位点上游引物)’和SFsg-R:5’AAAAGCACCGACTCGGTGCCACTTTTTCAAGTTGATAACGGACTAGCCTTATTTTAACTTGCTATTTC-3’(靶位点共用下游引物),以提取的草地贪夜蛾基因组DNA为模板,扩增反应为50μl体系,扩增程序为:98℃10s,55℃15s,68℃15s,累计35个循环;最后72℃10min。所用的扩增反应试剂盒为PrimeSTARGXL Premix(TakaRa公司产品)。得到的PCR扩增产物用MAXIscriptT7 In Vitro Transcription Kit试剂盒体(Invitrogen公司产品)体外合成sgRNA,合成好的sgRNA测定浓度后于-80℃保存备用。
步骤(2):收集草地贪夜蛾1小时内产的卵,通过显微注射将上述合成的两条sgRNA和Cas9蛋白(Invitrogen公司)的混合液一并注射进每一粒卵中。一共注射200粒卵。进行显微注射时,每条sgRNA的浓度为100ng/ul,Cas9蛋白浓度为300ng/ul,注射量均约为100nl。
步骤(3):所有注射后的卵粒放于养虫室内(温度27±1℃;光周期14h:10h(明:暗);相对湿度65±5%)孵化并单头饲养。
步骤(4):持续观察试虫的生长发育变化,并统计死亡率。结果显示,有169粒卵成功孵化,其中39个个体在幼虫阶段死亡,剩余个体均成功化蛹。化蛹的个体最终只有13个个体羽化正常,其余个体有的在蛹期死亡,有的羽化异常(蛹壳无法完全脱落)并最终死亡(图4),总体死亡率达90%以上;同时在同样条件正常饲养的非基因敲除品系的草地贪夜蛾试虫死亡率在5%以下。
结论:草地贪夜蛾SoxC基因被敲除后,试虫个体无法正常羽化存活,表明SoxC基因在羽化过程中具有重要作用,该基因具有开发成害虫防控药剂靶标的潜力,可用于开发制备防治控制草地贪夜蛾的药物或者试剂。
以上所述仅是本发明的优选实施方式,应当指出:对于本技术领域的普通技术人员来说,在不脱离本发明原理的前提下,还可以做出若干改进和润饰,这些改进和润饰也应视为本发明的保护范围。
